UNRELEASED

New features

  • feat: Added new tracing API (HIGHLY EXPERIMENTAL) supporting two RPC methods: trace_block and trace_replayBlockTransactions (filecoin-project/lotus#11100)

Improvements

v1.23.3 / 2023-08-01

This feature release of Lotus includes numerous improvements and enhancements for node operators, ETH RPC-providers and storage providers.

This feature release requires a minimum Go version of v1.19.12 or higher to successfully build Lotus. Go version 1.20 is also supported, but 1.21 is NOT.

Highlights

  • Lotus now includes a Slasher tool to monitor the network for Consensus Faults, and report them as appropriate
    • The Slasher investigates all incoming blocks, and assesses whether they trigger any of the three Consensus Faults defined in the Filecoin protocol
    • If any faults are detected, the Slasher sends a ReportConsensusFault message to the faulty miner
    • For more information on the Slasher, including how to run it, please find the documentation here
  • The Ethereum-like RPC exposed by Lotus is now compatible with EIP-1898: https://github.com/filecoin-project/lotus/pull/10815
  • The lotus-miner PieceReader now supports parallel reads: https://github.com/filecoin-project/lotus/pull/10913
  • Added new environment variable LOTUS_EXEC_TRACE_CACHE_SIZE to configure execution trace cache size (filecoin-project/lotus#10585)
    • If unset, we default to caching 16 most recent execution traces. Storage Providers may want to set this to 0, while exchanges may want to crank it up.

New features

Improvements

v1.23.2 / 2023-06-28

This is a patch release on top of 1.23.1 containing the fix for https://github.com/filecoin-project/lotus/issues/10906 This fixes the syncing issue seen by many node operators/SPs, usually when performing actions which would result in msgs staying in their mpool for longer periods of time (ex. PSD) resulting in these msgs being republished multiple times and possibly lowering your peer scores. Please refer to the above issue for more details. We'd recommend everyone to accept this fix to better overall network health

Improvements

  • fix: pubsub: do not treat ErrExistingNonce as Reject

v1.23.1 / 2023-06-20

This is an optional feature release of Lotus. This feature release includes numerous improvements and enhancements for node operators, ETH RPC-providers and storage providers.

☢️ Upgrade Warnings ☢️

If you are upgrading to this release candidate from Lotus v1.22.1, please make sure to read the upgrade warnings section in the v1.23.0 release first.

  • Storage providers: The Lotus-Miner legacy-markets has been disbled by default in this feature release and will be removed in the near term future. Users are adviced to migrate to Boost or other SP markets systems.

Highlights

🛣 Execution Lanes 🛣 This feature release introduces VM Execution Lanes! Execution lanes efficiently divide the workload between system processes (chainsync) and RPC requests. This way syncing the chain will not be at the mercy of responding to users' requests and RPC providers nodes should have less problems catching up.

To take advantage of VM Execution Lanes, you need to set up two environment variables:

  • LOTUS_FVM_CONCURRENCY - read more about how this value should be set to here
  • LOTUS_FVM_CONCURRENCY_RESERVED = 4

🧱 Aggregation / Batching fixes 🔨

Numerous aggregation and batching fixes has been included in the feature release. Large ProveCommitAggregate and PreCommitBatching messages that exceeds the block limit will now automatically be split into smaller messages when sent to the chain.

Additionally we have added a new feature that staggers the amount of ProveCommit messages sent simulatanously to the chain if a storage provider has been aggregating many sectors in ProveCommitAggregate message, but at the time of publishing the BaseFee is below the aggregation threshold. This stagger feature prevents issues where some of the ProveCommit messages fail with the SysErrorOutOfGas message. You can tweak how many messages will be staggered per epoch by changing MaxSectorProveCommitsSubmittedPerEpoch in the sealing section of the config.toml file.

NB: While these fixes are great for the reliability of aggregation and batching on the Lotus side, it has been uncovered that aggregating ProveCommit messages for sectors containing verified deals are currently more expensive then single messages due to an issue on the actors side. We therefore do not reccomend our users to aggregate ProveCommit messages when doing verified deals until that issue has been resolved. You can follow the discussion on resolving the issue on the actors side here.

Unsealing CLI/API

This feature release adds a dedicated lotus-miner sectors unseal command and API, allowing you to unseal specific sealed sectors easily.

New features

  • feat: VM Execution Lanes (filecoin-project/lotus#10551)
    • Adds VM exections lanes, efficiently dividing the workload between system processes and RPC-requests.
  • Add API and CLI to unseal sector (#10626) (filecoin-project/lotus#10626)
    • Adds lotus-miner sectors unseal cmd, and a API-method to unseal a sector.
  • feat: sealing: Split PCA/PCB batches if gas used exceeds block limit (filecoin-project/lotus#10647)
    • Splits ProveCommitAggregate and PreCommitBatch messages into multiple messages if the message exceeds the block limit.
  • Add feature to stagger sector prove commit submission (#10543) (filecoin-project/lotus#10543)
    • Staggers the amount of ProveCommit messages sent simultanously if a storage provider has been aggregating many message, but at the moment of publishing the BaseFee is below the threshold for aggregation to prevent unwanted SysErrorOutOfGas issues.
  • Set default for MaxSectorProveCommitsSubmittedPerEpoch (filecoin-project/lotus#10728)
    • Sets the default amount of ProveCommits submitted per epoch to 20.
  • feat: worker: Ensure tempdir exists (#10433) (filecoin-project/lotus#10433)
    • Ensures that a temporary directory exists on start of a lotus-worker with a custom TMPDIR set.
  • feat: sync: harden chain sync (#10756) (filecoin-project/lotus#10756)
  • feat: populate the index on snapshot import (filecoin-project/lotus#10556)
  • feat:chain: Message Index (HIGHLY EXPERIMENTAL) (filecoin-project/lotus#10452)
    • MVP of a message index that allows us to accelrate StateSearchMessage and related functionality, and eventually accelerate critical chain calls (follow up).
  • feat: Add small cache to execution traces (filecoin-project/lotus#10517)
  • feat: shed: incoming block-sub chainwatch tool (filecoin-project/lotus#10513)

v1.23.0 / 2023-04-21

This is the stable feature release for the upcoming MANDATORY network upgrade at 2023-04-27T13:00:00Z, epoch 2809800. This feature release delivers the nv19 Lighting and nv20 Thunder network upgrade for mainnet, and includes numerous improvements and enhancements for node operators, ETH RPC-providers and storage providers.

☢️ Upgrade Warnings ☢️

Please read carefully through the upgrade warnings section if you are upgrading from a v1.20.X release, or the v1.22.0 release. If you are upgrading from a v1.21.0-rcX these warnings should be familiar to you.

  • Starting from this release, the SplitStore feature is automatically activated on new nodes. However, for existing Lotus users, you need to explicitly configure SplitStore by uncommenting the EnableSplitstore option in your config.toml file. To enable SplitStore, set EnableSplitstore=true, and to disable it, set EnableSplitstore=false. It's important to note that your Lotus node will not start unless this configuration is properly set. Set it to false if you are running a full archival node!
  • This feature release requires a minimum Go version of v1.19.7 or higher to successfully build Lotus. Additionally, Go version v1.20 and higher is now also supported.
  • Storage Providers: The proofs libraries now have CUDA enabled by default, which requires you to install (CUDA)[https://lotus.filecoin.io/tutorials/lotus-miner/cuda/] if you haven't already done so. If you prefer to use OpenCL on your GPUs instead, you can use the FFI_USE_OPENCL=1 flag when building from source. On the other hand, if you want to disable GPUs altogether, you can use the FFI_NO_GPU=1 environment variable when building from source.
  • Storage Providers: The lotus-miner sectors extend command has been refactored to the functionality of lotus-miner sectors renew.
  • Exchanges/Node operators/RPC-providers:: Execution traces (returned from lotus state exec-trace, lotus state replay, etc.), has changed to account for changes introduced by the by the FVM. Please make sure to read the Execution trace format change section carefully, as these are interface breaking changes
  • Syncing issues: If you have been struggling with syncing issues in normal operations you can try to adjust the amount of threads used for more concurrent FMV execution through via the LOTUS_FVM_CONCURRENCY enviroment variable. It is set to 4 threads by default. Recommended formula for concurrency == YOUR_RAM/4 , but max during a network upgrade is 24. If you are a Storage Provider and are pushing many messages within a short period of time, exporting LOTUS_SKIP_APPLY_TS_MESSAGE_CALL_WITH_GAS=1 will also help with keeping in sync.
  • Catching up from a Snapshot: Users have noticed that catching up sync from a snapshot is taking a lot longer these day. This is largely related to the built-in market actor consuming a lot of computational demand for block validation. A FIP for a short-term mitigation for this is currently in Last Call and will be included network version 19 upgrade if accepted. You can read the FIP here.

Highlights

Execution Trace Format Changes

Execution traces (returned from lotus state exec-trace, lotus state replay, etc.), has changed to account for changes introduced by the FVM. Specifically:

  • The Msg field no longer matches the Filecoin message format as many of the message fields didn't make sense in on-chain sub-calls. Instead, it now has the fields To, From, Value, Method, Params, and ParamsCodec where ParamsCodec is a new field indicating the IPLD codec of the parameters.
    • Importantly, the Msg.CID field has been removed. This field is still present in top-level invocation results, just not inside the execution trace itself.
  • The MsgRct field no longer includes a GasUsed field and now has a ReturnCodec field to indicating the IPLD codec of the return value.
  • The Error and Duration fields have been removed as these are not set by the FVM. The top-level message "invocation result" retains the Error and Duration fields, they've only been removed from the trace itself.
  • Gas Charges no longer include "virtual" gas fields (those starting with v...) or source location information (loc) as neither field is set by the FVM.

A note on "codecs": FVM parameters and return values are IPLD blocks where the "codec" specifies the data encoding. The codec will generally be one of:

  • 0x51, 0x71 - CBOR or DagCBOR. You should generally treat these as equivalent.
  • 0x55 - Raw bytes.
  • 0x00 - Nothing. If the codec is 0x00, the parameter and/or return value should be empty and should be treated as "void" (not specified).

SplitStore

This feature release introduces numerous improvements and fixes to tackle SplitStore related issues that has been reported. With this feature release SplitStore is automatically activated by default on new nodes. However, for existing Lotus users, you need to explicitly configure SplitStore by uncommenting the EnableSplitstore option in your config.toml file. To enable SplitStore, set EnableSplitstore=true, and to disable it, set EnableSplitstore=false. It's important to note that your Lotus node will not start unless this configuration is properly set. Set it to false if you are running a full archival node!

SplitStore also has some new configuration settings that you can set in your config.toml file:

  • HotstoreMaxSpaceTarget suggests the max allowed space (in bytes) the hotstore can take.
  • HotstoreMaxSpaceThreshold a moving GC will be triggered when total moving size exceeds this threshold (in bytes).
  • HotstoreMaxSpaceSafetyBuffer a safety buffer to prevent moving GC from an overflowing disk.

The SplitStore also has two new commands:

  • lotus chain prune hot is a much less resource-intensive GC and is best suited for situations where you don't have the spare disk space for a full GC.
  • lotus chain prune hot-moving will run a full moving garbage collection of the hotstore. This commands create a new hotstore before deleting the old one so you need working room in the hotstore directory. The current size of a fully GC'd hotstore is around 295 GiB so you need to make sure you have at least that available.

You can read more about the new SplitStore commands in the documentation.

RPC API improvements

This feature release includes all the RPC API improvements made in the Lotus v1.20.x patch releases. It includes an updated FFI that sets the FVM parallelism to 4 by default.

Node operators with higher memory specs can experiment with setting LOTUS_FVM_CONCURRENCY to higher values, up to 48, to allow for more concurrent FVM execution.

Experimental scheduler assigners

In this release there are four new expirmental scheduler assigners:

  • The experiment-spread-qcount - similar to the spread assigner but also takes into account task counts which are in running/preparing/queued states.
  • The experiment-spread-tasks - similar to the spread assigner, but counts running tasks on a per-task-type basis
  • The experiment-spread-tasks-qcount - similar to the spread assigner, but also takes into account task counts which are in running/preparing/queued states, as well as counting running tasks on a per-task-type basis. Check the results for this assigner on (storage-only lotus-workers here).
  • The experiment-random - In each schedule loop the assinger figures a set of all workers which can handle the task and then picks a random one. Check the results for this assigner on (storage-only lotus-workers here).

Graceful shutdown of lotus-workers We have cleaned up some commands in the lotus-worker to make it less confusing how to gracefully shutting down a lotus-worker while there are incoming sealing tasks in the pipeline. To shut down a lotus-worker gracefully:

  1. lotus-worker tasks disable --all and wait for the worker to finish processing its current tasks.
  2. lotus-worker stop to detach it and do maintenance/upgrades.

CLI speedups

The lotus-miner sector list is now running in parallel - which should speed up the process from anywhere between 2x-10x+. You can tune it additionally with the check-parallelism option in the command. The Lotus-Miner info command also has a large speed improvement, as calls to the lotus legacy market has been removed.

v1.22.1 / 2023-04-23

Important Notice

This is a MANDATORY hotfix release that fixes a consensus-critical bug that was in v1.22.0 -- the necessary fix is https://github.com/filecoin-project/ref-fvm/pull/1750 and it is integrated into lotus via https://github.com/filecoin-project/lotus/pull/10735. You can NOT use 1.22.0 for the nv19 upgrade, you MUST be on 1.22.1 or higher.

About This Release

This is the stable release of Lotus v1.22.1 for the upcoming MANDATORY network upgrade at 2023-04-27T13:00:00Z, epoch 2809800. This release delivers the nv19 Lighting and nv20 Thunder network upgrade for mainnet.

Note that you must be on a go version higher than Go 1.18.8, but lower than Go v1.20.0. We would recommend Go 1.19.7.

The Lighting and Thunder upgrade introduces the following Filecoin Improvement Proposals (FIPs), delivered by builtin-actors v11 (see actors v11.0.0):

  • FIP 0060 - Thirty day market deal maintenance interval
  • FIP 0061 - WindowPoSt grindability fix
  • FIP 0062 - Fallback method handler for multisig actor

Expedited nv19 Lightning ⚡️ rollout

In light of the recent degraded chain quality on the mainnet an expedited nv19 upgrade has been proposed and accepted to roll out the market cron mitigation (FIP0060) that will improve block validation times, and with that the delay in block production that is causing a decrease in the chain quality currently.

With this expedited roll out we want to inform you of some key changes and important dates:

The Lighting and Thunder upgrade now implements the following Filecoin Improvement Proposals (FIPs), delivered by builtin-actors v11 (see actors v11.0.0):

  • FIP 0060 - Thirty day market deal maintenance interval
  • FIP 0061 - WindowPoSt grindability fix
  • FIP 0062 - Fallback method handler for multisig actor

1.20.0 / 2023-02-28

This is a MANDATORY release of Lotus that delivers the Hygge network upgrade, introducing Filecoin network version 18. The centerpiece of the upgrade is the introduction of the Filecoin Virtual Machine (FVM)’s Milestone 2.1, which will allow for EVM-compatible contracts to be deployed on the Filecoin network. This upgrade delivers user-programmablity to the Filecoin network for the first time!

The Filecoin mainnet is scheduled to upgrade to nv18 at epoch 2683348, on March 14th at 2023-03-14T15:14:00Z. All node operators, including storage providers, must upgrade to this release before that time. Storage providers must update their daemons, miners, market and worker(s)/boost. At the upgrade, a short migration will run that converts code actors v9 code CIDs to v10 CIDs, and installs the new Ethereum Address Manager singleton (see below). This is expected to be a lightweight migration that causes no service disruption.

The Hygge upgrade introduces the following Filecoin Improvement Proposals (FIPs), delivered in FVM3 (see FVM v3.0.0) and builtin-actors v10 (see actors v10.0.0):

  • FIP-0048: f4 Address Class
  • FIP-0049: Actor events
  • FIP-0050: API between user-programmed actors and built-in actors
  • FIP-0054: Filecoin EVM runtime (FEVM)
  • FIP-0055: Supporting Ethereum Accounts, Addresses, and Transactions
  • FIP-0057: Update gas charging schedule and system limits for FEVM

Filecoin Ethereum Virtual Machine (FEVM)

The Filecoin Ethereum Virtual Machine (FEVM) is built on top of the WASM-based execution environment introduced in the Skyr v16 upgrade. The chief feature introduced is the ability for anyone participating in the Filecoin network to deploy their own EVM-compatible contracts onto the blockchain, and invoke them as appropriate.

New Built-in Actors

The FEVM is principally delivered through the introduction of the new EVM actor. This actor “represents” smart contracts on the Filecoin network, and includes an interpreter that implements all EVM opcodes as their Filecoin equivalents, and translates state I/O operations to be compatible with Filecoin’s IPLD-based data model. For more on the EVM actors, please see FIP-0054.

The creation of EVM actors is managed by the new Ethereum Address Manager actor (EAM), a singleton that is invoked in order to deploy EVM actors. In order to make usage of the FEVM as seamless as possible for users familiar with the Ethereum ecosystem, this upgrades also introduces a dedicated actor to serve as “Ethereum Accounts”. This actor exists to allow for secp keys to be used in the Ethereum addressing scheme. The last new built-in actor introduced is the Placeholder actor, a thin “shell” of an actor that can transform into either EVM or EthAccount actors. For more on the EAM, EthAccount, and Placeholder actors, please see FIP-0055.

v10 Built-in actor bundles

Bundles for all networks (mainnet, calibnet, etc.) are included in the lotus source tree (build/actors/) and embedded on build, for v10 actors you can find it here. Reminder: Lotus verifies that the bundle CIDs are the right ones upon build & upgrade against the values in build/builtin_actors_gen.go, according to the network you are building. You may also check the bundle manifest CID matches the bundle gen-ed values by running lotus state actor-cids --network-version 18.

The manifest CID & full list of actor code CIDs for nv18 using actor v10 is:

Node Operators

FVM has been running in lotus since v1.16.0 and up, and the new FEVM does not increase any node hardware spec requirement.

With FEVM on Filecoin, we aim to provide full compatibility with the existing EVM ecosystem and its tooling out of the box. Consequently, lotus now provides a full set of Ethereum-styled APIs for developers and token holders to interact with the Filecoin network as well. For full documentation on this new tooling, please see the Lotus docs website.

Enabling Ethereum JSON RPC API

Note that Ethereum APIs are only supported in the lotus v1 API, meaning that any node operator who wants to enable Eth API services must be using the v1 API, instead of the v0 API. To enable Eth RPC, simply set EnableEthRPC to true in your node config.toml file; or set env var LOTUS_FEVM_ENABLEETHRPC to 1 before starting your lotus node.

Eth tx hash and Filecoin message CID

Most of the Eth APIs take Eth accounts and tx has as an input, and they start with 0x , and that is what Ethereum tooling support. However, in Filecoin, we have Filecoin account formats where things start with f (f410 specifically for eth accounts on Filecoin) and the messages are in the format of CIDs. To enable a smooth developer experience, Lotus internally converts between Ethereum address and Filecoin account address as needed. In addition, lotus also keeps a Eth tx hash <> Filecoin message CID map and stores them in a SQLite database as node sees a FEVM messages. The database is initiated and the maps are populated automatically in ~/<lotus_repo>/sqlite/txhash.db for any node that as Eth RPC enabled. Node operators can configure how many historical mappings they wanna store by configuring EthTxHashMappingLifetimeDays .

Events

FIP-0049 introduces actor events that can be emitted and externally observable during message execution. An events.db is created automatically under ~/<lotus_repo>/sqlite to store these events if the node has Eth RPC enabled. Node operators can configure the events support base on their needs by configuration Events configurations.

Note: All three features are new, and we welcome user feedback, please create an issue if you have any enhancements that you’d like to see!

1.19.0 / 2022-12-07

This is an optional feature release of Lotus. This feature release includes the SplitStore beta, the experimental Lotus node cluster feature, as well as numerous enhancments and bugfixes.

Highlights

🟢 SplitStore v2（Beta) 🟢

Splitstore aims to reduce the node performance impact that's caused by the Filecoin's very large, and continuously growing chain datastore by having a hot and cold blockstore. You can find more about the Splitstore implementation here. Splitstore has three basic modes for node operators to configure according to your needs:

  • discard: hotstore only, automatically archive out-of-scope objects that are beyond 4 finalities(3600 epochs).
  • universal: stores all chain data that's beyond 4 finalities into coldstore.
  • messages: only stores on-chain messages into coldstore.

The EnableColdStoreAutoPrune= configuration is being deprecated in this release, as there is only ever one compaction running. We welcome all node operators to try the new feature and let us know here if you have any feedback! There are more configuration one may set, you can read the full documentation about the SplitStoreV2 here: https://lotus.filecoin.io/lotus/configure/splitstore/.

🧪 Node Cluster (EXPERIMENTAL.) 🧪

The Lotus HA node cluster feature allows you to run multiple Lotus daemons for the same lotus-miner increasing resiliency. We welcome all Lotus users to join the early testing for this feature and provide your feedback. Please note that this feature is targeted towards more enterprise users of Lotus and requires at least 3 lotus nodes to be set up in a cluster. Check out the documentation here: https://lotus.filecoin.io/lotus/configure/clusters/

⭐️ SnapDeals Enhancements ⭐️

Numerous SnapDeals related improvements and fixes made it into this release before the code freeze. Some the highlights of the issues that has been fixed in this feature release are:

  • Unable to snap-up a sector again if something went wrong. - This has now been fixed ✅
  • Error messages on loop during an open deadline. - This has now been fixed ✅

New features

  • feat:splitstore:single compaction that can handle prune aka two marksets one compaction (#9571) (filecoin-project/lotus#9571)
    • Introduces a new SplitStore-mode, messages, which will only store on-chain messages. Fixes previously issues with regards to AutoPrune not compacting the coldstore. Link to documentation
  • feat: Raft consensus for lotus nodes in a cluster (filecoin-project/lotus#9294)
    • Adds the experimental node cluster feature.
  • feat: storage: Force exit GenerateSingleVanillaProof on cancelled context (filecoin-project/lotus#9613)
    • GenerateSingleVanillaProof now respects context, which means that it will skip slow to read sectors 🐌 and return a context error. Instead of being blocked forever if storage reads where blocked (e.g disconnected NFS).
  • feat: wdpost: Configurable pre-check timeouts (filecoin-project/lotus#9680)
    • Adds configuration knobs for setting custom amount of time a proving pre-check can take before a sector and partition will be skipped. Link to documentation
  • feat: chain: future proof the from & to address protocols (filecoin-project/lotus#9515)
    • This lets us add new address protocols to go-address without implicitly accepting them in messages on the network.
  • feat: Retrieval into remote blockstores (filecoin-project/lotus#9565)
    • Makes it possible to point retrievals at a network-backed blockstore.
  • feat: Add node uptime rpc / output in info command (filecoin-project/lotus#9436)
    • Adds node uptime stats to the lotus-miner info and lotus info commands
  • feat: wdpost: Add ability to only have single partition per msg for partitions with… (filecoin-project/lotus#9413)
    • Adds a configuration option to have a single partition per PoSt Message for partitions containing recovering sectors.
  • feat: miner paramfetch: Don't fetch param files when not needed (filecoin-project/lotus#9391)
    • A Lotus-Miner processes that has disabled local PoSt / C2 / PR2 does not need the param-files. This makes node startup much faster, reducing downtime by a lot when restarts are needed.
  • feat: client: Add retrieval deal ID and bytes transferred to retrieval output (filecoin-project/lotus#9398)
    • Appends retrieval deal ID and bytes transferred to the retrieval output.
  • feat: dealpublisher: check for duplicate deals before adding (filecoin-project/lotus#9365)
  • feat: Drop active retrieval check (#764) (filecoin-project/go-fil-markets#764)
  • feat(retrievalmarkets): expose GetDynamicAsk (#748) (filecoin-project/go-fil-markets#748)
  • feat: handle retrieval queries for unindexed identity payload CIDs (#747) (filecoin-project/go-fil-markets#747)
  • feat: add a method for validating an address for a network version (#115) (filecoin-project/go-state-types#115)

Improvements

  • fix: miner-cli: Fix lotus-miner proving check (filecoin-project/lotus#9643)
    • Fixes the issue where the lotus-miner proving check command always outputted Error: rg is nil
  • fix: sealing pipeline: Clear CreationTime when starting sector upgrade (filecoin-project/lotus#9642)
    • Fixes the issue where an aborted SnapDeal upgrade could no longer be retried with SnapDeals.
  • fix:sealing-fsm:wait mutable fsm state for immutable sector upgrade error (filecoin-project/lotus#9598)
    • Creating a new WaitMutable state - now if the deadline is open and the sectors are trying finalize they will wait on the worker until the deadline has closed. Important to note that they will not finalize as soon as the deadline closes, they will wait 1h before continuing. Fixes the previous issue where upgraded Snap-sectors for an open deadline cause a lot of error-messages and p_aux issues
  • fix: cli: add beneficiary info to lotus-miner actor control list (filecoin-project/lotus#9632)
    • Adds the beneficiary address to the lotus-miner actor control list output.
  • fix: sealing pipeine: Release assigned deals on snapdeals abort (filecoin-project/lotus#9601)
  • fix: docker: make compatible with arm platform (filecoin-project/lotus#9363)
    • Makes the Dockerfile.lotus compatible with ARM-platforms (e.g Mac M1).
  • fix: post worker sched: Don't check worker session in a busy loop (filecoin-project/lotus#9495)
    • Fixes a looping pattern which could result in a flood of requests between lotus-miner<->lotus-worker, potentially exhausting resources needed to make http requests, that lead to all sorts of random RPC-related issues.
  • fix: miner: init miner's with 32GiB sectors by default (filecoin-project/lotus#9364)
    • Makes the lotus-miner init defualt to 32GiB sectors.
  • fix: store identity CIDs in CARs for online deals (#749) (filecoin-project/go-fil-markets#749)
  • fix: cliutil: Fix URL-based API endpoint parsing

Note to SPs: If you are running into issue with updating your miner node from an earlier release and is failing to restart your miner, check your journalctl and see if you noticed the following error:

New sector storage: <%d>
Nov 19 15:03:43 g0lotus01 lotus-miner[<id>]: ERROR: creating node: starting node: could not build arguments for function "reflect".makeFuncStub (/usr/local/go/src/reflect/asm_amd64.s:28): failed to build *paths.Local: received non-nil error from function "reflect".makeFuncStub (/usr/local/go/src/reflect/asm_amd64.s:28): opening path /media/data1/lotusstorage: path with ID <%d> already opened: '<path>'

If so, this check is introduced via #9032, precisely this line. It's added to prevents double-attaching paths given it's now possible to manipulate paths at runtime. Verify storage.json configs if you encounter this error or remove the undesired depulicated path as you see fit accordingly.

1.18.0 / 2022-11-15

⚠️ Please note that from Lotus v1.17.2&^ will require a Go-version of v1.18.1&^

This is the final release of the upcoming MANDATORY release of Lotus that introduces Filecoin network v17, codenamed the Shark upgrade. Shark upgrade delivers a wave of protocol refinements that will allow for useful smart contracts to be written using the FVM (eg. programmable markets, lending contracts, etc.).

The Filecoin mainnet is scheduled to upgrade to nv17 at epoch 2383680, on Nov 30th on 2022-11-30T14:00:00Z. All node operators, including storage providers, must upgrade to this release before that time. Storage providers must update their daemons, miners, market and worker(s)/boost.

The Shark upgrade introduces the following FIPs, delivered in actors v9:

  • FIP0029 Beneficiary Address for Storage Providers: step towards better lending market for SP
  • FIP0034 Fix PreCommit Deposit Independent of Sector Content: resolves a significant weakening of Filecoin PoRep’s security guarantees
    • ❗Pre-commit deposit will be calculated as the 20-day projection of expected reward earned by a sector with a sector quality of 10 (i.e. full of verified deals), regardless of sector content. The Initial Pledge value, due when the sector is proven, is left unchanged.
  • FIP0041 Forward Compatibility for PreCommit: enables a cleaner and easier transition to Programmable Storage Markets
  • FIP0044 Standard Message Authentication: enable metadata authentication for user defined actor
  • FIP0045 Decoupling Fil+ from Marketplace: DataCap and the 10x QAP is now only associated with how long DATA is wanted to be stored on the network.
    • This is a transitional state to enabling far more efficient and dynamic storage markets on Filecoin network in the future.
    • ⭐️ First Fungible Token Contract - Datacap Actor, on Filecoin! (fungible token standard, token contract library).
    • For storage deal participants (clients and storage providers):
      • PublishStorageDeals/ProveCommit(Aggregate)/ProveReplicaUpdates message that includes verified deals will see a gas usage increase, more details can be found here
      • Term is introduced for defining how long the DataCap is assigned to a piece of data. Anyone who cares about that piece of data may extend the term, which incentives SPs to store the data longer on the network without a new deal/resealing.
      • There is no more diluted verified deal QAP due to deal/sector space time for new sectors that contains verified deals after this upgrade.
      • SPs may enjoy 90 days of extra QAP than deal duration by default, given term_max is always deal duration + 90 days. ❗ We highly recommend all lotus users, especially storage providers, developers and clients to read the FIPs in detail to understand the protocol changes and potential impact to network participants!

Snapshots

The #fil-infra team at PL has launched a brand new Lightweight Filecoin Chain Snapshots Service to support chain management needs for the node operators, check here for the full detail. We are planning to switch the snapshot service listed in lotus docs to the new Lightweight Filecoin Chain Snapshots Service by EOY, and deprecate public support of the current snapshots production. We recommend all users to test and switch the new service ASAP, and if you run into any issue, please report them here and the team would be happy to support you! For the main differences between the old & the new service, checkout the FAQ section here

Migration

We are expecting a heavier than normal state migration for this upgrade due to the amount of the state changes introduced. All node operators, including storage providers, should be aware that two pre-migrations are being scheduled. The first pre-migration will begin at 2022-11-30T12:00:00Z (120 minutes before the real upgrade), the second pre-migration will begin at 2022-11-30T13:45:00Z (7.5 minutes before the real upgrade). The first pre-migration will take up to 1.5hr, depending on the amount of the historical state in the node blockstore and the hardware specs the node is running on. During this time, expect slower block validation times, increased CPU and memory usage, and longer delays for API queries. We recommend node operators (who haven't enbabled splistore universal mode) that do not care about historical chain states, to prune the chain blockstore by syncing from a snapshot 1-2 days before the upgrade. Note to full archival node operators: you may expect a migration that takes up to 20 min upon the upgrade, during this period your node will fall out of sync and your chain service may have some disruption. However, you can expect the node to catch up soon after the migration completes.

v9 Built-in actor bundles

Bundles for all networks(mainnet, calibnet, and etc) are included in the lotus source tree (build/actors/) and embedded on build, for v9 actors you can find it here. Reminder: Lotus verifies that the bundle CIDs are the right ones upon build & upgrade against the values in build/builtin_actors_gen.go, according to the network you are building. You may also check the bundle manifest CID matches the bundle gen-ed values by running lotus state actor-cids --network-version 17.

The manifest CID & full list of actor code CIDs for nv17 using actor v9 is:

v1.17.2 / 2022-10-05

This is an OPTIONAL release of Lotus. This feature release introduces new sector number management APIs in Lotus that enables all the Sealing-as-a-Service and Lotus interactions needed to function. The default propagation delay setting for storage providers has also been changed, as well as numerous other features and enhancements. Check out the sub-bullet points in the feature and enhancement section to get a short description about each feature and enhancements.

Highlights

🦭 SaaS 🦭 New sector management APIs makes it possible to import partially sealed sectors into Lotus. This release implements all SaaS<->Lotus interactions needed for such services to work. Deep dive into the new APIs here: https://github.com/filecoin-project/lotus/discussions/9079#discussioncomment-3652044

⏳ Propagation delay ⌛️ In v1.17.2 the default PropagationDelay has been raised from 6 seconds -> 10 seconds, and you can tune this yourself with the PROPAGATION_DELAY_SECS environment variable. This means you will now wait for 10 seconds for other blocks to arrive from the network before computing a winningPoSt (if eligible). In your lotus-miner logs that means you will see this "baseDeltaSeconds": 10 as default.

⚠️ Please note that Lotus v1.17.2 will require a Go-version of v1.18.1 or higher!

New features

  • feat: sealing: Partially sealed sector import (filecoin-project/lotus#9210)
    • Implements support for importing (partially) sealed sectors which is needed for enabling external sealing services.
  • feat: sealing: Use bitfields to manage sector numbers (filecoin-project/lotus#9183)
    • Needed for Sealing-as-a-Service. Move sector number assigning logic to use stored bitfields instead of stored counters. Makes it possible to reserve ranges of sector numbers, see the sector assigner state and view sector number reservations.
  • feat: env: propagation delay (filecoin-project/lotus#9290)
    • The default propagation delay is raised to 10 seconds from 6 seconds. Ability to set it yourself with the PROPAGATION_DELAY_SECS environment variable.

    • A new lotus info command that prints useful node information in one place.
  • feat: proving: Introduce manual sector fault recovery (#9144) (filecoin-project/lotus#9144)
    • Allow users to declare fault recovery messages manually with the lotus-miner proving recover-faults command, rather than waiting for it to happen automatically before windowPost.
  • feat: api: Reintroduce StateActorManifestCID (filecoin-project/lotus#9201)
    • Adds ability to retrieve the Actor Manifest CID through the api.
  • feat: message: Add uuid to mpool message sent to chain node from miner (filecoin-project/lotus#9174)
  • feat: message: Add retries to mpool push message from lotus-miner (filecoin-project/lotus#9177)
    • Retries to mpool push message API in case of unavailability of the lotus chain node.

Network 17 related features :

    • Makes the command defaults to the current network.
  • fix: ux: Output bytes in lotus client commP cmd (filecoin-project/lotus#9189)
    • Adds an additional line that outputs bytes in the lotus client commP command.
  • fix: sealing: Add information on what worker a job was assigned to in logs (filecoin-project/lotus#9151)
    • Adds the worker hostname into the assignment logs.
  • refactor: sealing pipeline: Remove useless storage adapter code (filecoin-project/lotus#9142
    • Remove proxy code in storage/miner.go / storage/miner_sealing.go, call the pipeline directly instead.

    • configure MaxPartitionsPerPoStMessage in miner configuration setting.

1.16.0 / 2022-06-24

This is a MANDATORY release of Lotus that introduces Filecoin network v16, codenamed the Skyr upgrade.

The network is scheduled to upgrade to nv16 at epoch 1960320, on July 6th at 2022-07-06T14:00:00Z. All node operators, including storage providers, must upgrade to this release (or a later release) before that time. Storage providers must update their daemons, miners, market and worker(s).

Your lotus node will switch from the Legacy VM (that depended on go-based specs-actors) to Filecoin Virtual Machine FVM (that uses Rust-based builtin-actors) atomically upon the upgrade.

The Skyr upgrade introduces the following FIPs, enhancements and bug fixes, delivered in built-actors v8 and ref-fvm v1.0.0:,

🆕 Things you may wanna know

Actor Code CIDs

As stated in FIP-0031- structure of the code cid, system actors' code CIDs will be real content-addressing

For lotus users, we are making the change minimal for you. This means the CODE output when you run lotus state get-actor will now be the actual CID that represents the executable code for the actor, followed by wrapped synthetic id like the ones you've got before, i.e fil/8/system.

Moreover, this also means that in the future, whenever the actor code changes, the CID changes accordingly, and a network upgrade is needed for the network participants to have consensus over what executable code we should use for each system actor.

Built-in actor bundles

As the network introduces FVM, it's also switching from spec-actor (written in GoLang) to built-in actor (written in rust), in which the latter comes with importable bundles. This means, like filecoin proof parameters, node operators now also need to fetch the actor bundles according to the network versions for the nodes to remain operational.

Bundles for all networks(mainnet, calibnet, and etc) are included in the lotus source tree (build/actors/) and embedded on build. Lotus verifies that the bundle CIDs are the right ones upon build & upgrade against the values in build/builtin_actors_gen.go, according to the network you are building. You may also check the bundle manifest CID matches the bundle gen-ed values by running lotus state actor-cids --network-version 16.

The manifest CID & full list of actor code CIDs for nv16 using v8.0.0 is:

    "_manifest":         "bafy2bzacebogjbpiemi7npzxchgcjjki3tfxon4ims55obfyfleqntteljsea"
	"account":          "bafk2bzacedudbf7fc5va57t3tmo63snmt3en4iaidv4vo3qlyacbxaa6hlx6y"

	"verifiedregistry": "bafk2bzaceb3zbkjz3auizmoln2unmxep7dyfcmsre64vnqfhdyh7rkqfoxlw4"

All bundles are also available at https://github.com/filecoin-project/builtin-actors/releases, thus you can also manually download the bundles and place them in the right path.

Note: use customized bundle will risk you to lose sync with the network!

To get Code CIDs:

  • api:StateActorCodeCIDs
  • cli: lotus state actor-cids
  • cli: lotus-shed cid inspect-bundle

Execution Trace

For developers that are dependent on lotus execution trace, you will need to enable LOTUS_VM_ENABLE_TRACING envvar to get the exact execution trace response as before. Without the envvar enabled, Subcall details, DurationandGasCharges` fields will be missing from the new FVM trace.

Deal Proposal Migration

All deal proposals with non-utf8 string as the label in the metadata store will perform a light migration to new format as defined in v1.1.1.

Others

  • Resource manager is now only enabled by default on full daemon node. You can enable it manually for other nodes by setting env var LOTUS_RCMGR to 1.
  • Fix: drand: calculation of round from Filecoin epochs (filecoin-project/lotus#8606)

Dependency Update

1.15.2 / 2022-05-06

This is a highly recommended feature lotus release v1.15.2. This feature release introduces many new features and for SPs, including PoSt workers, sealing scheduler, snap deal queue and so on.

Note: You need to be using go v1.18.1&up from this release onwards.

Highlights

❣️❣️❣️ PoSt Workers ❣️❣️❣️

‼️️Attention - the long-awaited yet highly requested PoSt workers, they are here! And they come in as a combo: you may setup PoSt workers for both winningPoSt or/and windowPoSt worker. You can also setup any number of PoSt workers as long as you have the hardware resources! For more details and learn how to set it up, see the docs here. You can also find early result of the PoSt workers performance by the community here.

In addition, we also added some handy toolings:

  • feat: miner: API/CLI to compute window-post (filecoin-project/lotus#8389)
    • run lotus-miner proving compute window-post to manually trigger a full windowPoSt computation for a specific deadline for full sanity checks.
  • feat: miner cli: Separate proving workers command (filecoin-project/lotus#8379)
    • run lotus-miner proving workers to list all the PoSt workers that's attached
  • feat: miner cli: proving check --faulty, faults in storage list sectors (filecoin-project/lotus#8349)
    • run lotus-miner proving check --faulty to identify the sectors that might be bad.

🔥🔥🔥 Sealing Scheduler Enhancement 🔥🔥🔥

Have you ever got a couple workers but only a few of them are super packed, while the rest are idling waiting for jobs? Now the task can be distributed more evenly with:

🌟🌟🌟 Snap Deal Enhancements 🌟🌟🌟

The Filecoin Network introduced Snap Deal with the network v15 OhSnap upgrade, and lotus shipped v1.14.0 with basic snappy support for SP to use this feature. Since then, we have received good ux feedbacks and bug reports from the community, and we are introducing a couple enhancement for SPs to better leverage this feature.

1.15.1 / 2022-04-07

This is a HIGHLY recommended feature release v1.15.1, especially for node operators and storage providers who want to be a part of the content addressing network of Filecoin and IPFS. This feature release introduces Index Provider, GraphSync v2, and many other latest functionalities, improvements and bug fixes. More importantly, node operator can now enable the FVM(experimental) to sync mainnet!!

Highlights

🔥🔥🔥 FVM (Experimental) 🔥🔥🔥

🌟🌟🌟 Index Provider (Production Ready!) 🌟🌟🌟

More and more useful data is being stored on Filecoin via deals made by clients to Storage Providers. The goal is that this content is discoverable when people need them. To achieve that goal, one of the projects the Bedrock team is working on is building an Indexer Ecosystem, a project that's focus on content addressing on Filecoin, then potentially have interoperability with IPFS in the future and eventually serve the retrieval market. The Indexer Ecosystem high level architecture overview diagram can be found here and a detailed write up about can be found here.

That being said, with this release, lotus Storage Providers can easily become an Index Provider and serve the Indexer Content Addressing System. Index Providers generate advertisements from the deals made by a storage provider and announces the data to the indexer nodes for further processing:

  • To learn more about what is an Index Provider and how to be an Index Provider, read it here in lotus docuementation.
  • An one-off migration is needed in order for a Storage Provider to become an Index Provider and announce the proper formatted index. It's highly recommended for all Index Provider to do a force bulk initialization to enable index announcement on all existing deals.
    • Note that the Initialization places IO workload on your storage system. SP should set a proper concurrency based on your hardware or can stop/start initialization at their wish/convenience as proving deadlines approach and elapse, to avoid IOPS starvation or competition with window PoSt.
  • After the first one-time migration, being an Index Provider barely puts any extra usage on SP's market system.
    • You can find the testing result by SPX fellows here.

We recommend all Storage Providers that are serving deals in the Filecoin network to become a Index Provider, make the data you are storing discoverable for the retrieval market and retrieval clients!

❗️❗️❗️ Dag Migration For New CAR index format in DagStore ❗️❗️❗️

The index provider leverages the latest CARv2 indexing format MultihashIndexSorted, which stores the multihash code as well as the digest of all CIDs in a CAR file. Thus, all Storage Providers SHOULD perform an one-off DAG mirgation to regenerate DagStore CARv2 indices. You have to do it to become an index provider, failing to do so may also impact your future deal making. Follow the instruction here to perform the migration.

1.14.4 / 2022-03-03

This is a highly recommended optional release for storage providers that are doing snap deals. This fix the bug that causes some snap deal sectors are stuck in FinalizeReplicaUpdate. In addition, SPs should be able to force update sectors status without getting blocked by normal shutdown of state machine.

v1.14.3 / 2022-02-28

This is an optional release, that includes a fix to properly register the --really-do-it flag for abort-upgrade.

1.14.2 / 2022-02-24

This is an optional release of lotus, that's had a couple more improvements w.r.t Snap experience for storage providers in preparation of theupcoming OhSnap upgrade.

Note that the network is STILL scheduled to upgrade to v15 on March 1st at 2022-03-01T15:00:00Z. All node operators, including storage providers, must upgrade to at least Lotus v1.14.0 before that time. Storage providers must update their daemons, miners, and worker(s).

Wanna know how to Snap your deal? Check this out!

Bug Fixes

  • fix lotus-bench for sealing jobs (#8173)
  • fix:sealing:really-do-it flag for abort upgrade (#8181)
  • fix:proving:post check sector handles snap deals replica faults (#8177)
  • fix: sealing: missing file type (#8180)

Others

  • Retract force-pushed v1.14.0 to work around stale gomod caches (#8159): We originally tagged v1.14.0 off the wrong commit and fixed that by a force push, in which is a really bad practise since it messes up the go mod. Therefore, we want to retract it and users may use v1.14.1&^.

1.14.1 / 2022-02-18

This is an optional release of lotus, that fixes the incorrect comment of network v15 OhSnap upgrade date. Note the actual upgrade epoch in v1.14.0 was correct.

1.14.0 / 2022-02-17

This is a MANDATORY release of Lotus that introduces Filecoin network v15, codenamed the OhSnap upgrade.

The network is scheduled to upgrade to v15 on March 1st at 2022-03-01T15:00:00Z. All node operators, including storage providers, must upgrade to this release (or a later release) before that time. Storage providers must update their daemons, miners, and worker(s).

The OhSnap upgrade introduces the following FIPs, delivered in actors v7:

It is recommended that storage providers download the new params before updating their node, miner, and workers. To do so:

  • Download Lotus v1.14.0 or later
  • run make lotus-shed
  • run ./lotus-shed fetch-params with the appropriate proving-params flag
  • Upgrade the Lotus daemon and miner when the previous step is complete

All node operators, including storage providers, should be aware that a pre-migration will begin at 2022-03-01T13:30:00Z (90 minutes before the real upgrade). The pre-migration will take between 20 and 50 minutes, depending on hardware specs. During this time, expect slower block validation times, increased CPU and memory usage, and longer delays for API queries.

        • lotus client cat: retrieve and print the data from the network
      • 🌟🌟 The monolith ClientRetrieve method was broken into:
        • ClientRetrieve which retrieves data into the local repo (or into an IPFS node if ipfs integration is enabled)
        • ClientRetrieveWait which will wait for the retrieval to complete
        • ClientExport which will export data from the local node
        • Note: this change only applies to v1 API. v0 API remains unchanged.
      • 🌟 Support for full ipld selectors was added (for example making it possible to only retrieve list of directories in a deal, without fetching any file data)
        • To learn more, see here
  • 🚀🚀 Sealing scheduler enhancements (#7703, #7269), #7714

v1.13.0 / 2021-10-18

Lotus v1.13.0 is a highly recommended feature release for all lotus users(i.e: storage providers, data brokers, application developers and so on) that supports the upcoming Network v14 Chocolate upgrade. This feature release includes the latest functionalities and improvements, like data transfer rate-limiting for both storage and retrieval deals, proof v10 with CUDA support, etc. You can find more details in the Changelog below.

Highlights

  • Enable separate storage and retrieval transfer limits (filecoin-project/lotus#7405)
    • SimultaneousTransfer is now replaced by SimultaneousTransfersForStorage and SimultaneousTransfersForRetrieval, where users may set the amount of ongoing data transfer for storage and retrieval deals in parallel separately. The default value for both is set to 20.
    • If you are using the lotus client, these two configuration variables are under the Client section in ./lotus/config.toml.
    • If you are a service provider, these two configuration variables should be set under the Dealmaking section in /.lotusminer/config.toml.
  • Update proofs to v10.0.0 (filecoin-project/lotus#7420)
    • This version supports CUDA. To enable CUDA instead of openCL, build lotus with FFI_USE_CUDA=1 FFI_BUILD_FROM_SOURCE=1 ....
    • You can find additional Nvidia driver installation instructions written by MinerX fellows here and perf improvements result on PC2/C2/WindowPoSt computation on different profiles here, most people observe a 30-50% decrease in computation time.

v1.11.2 / 2021-09-06

lotus v1.11.2 is a feature release that's highly recommended ALL lotus users to upgrade, including node operators, storage providers and clients.

Highlights

  • 🌟🌟🌟 Introduce Dagstore and CARv2 for deal-making (#6671) (filecoin-project/lotus#6671)
    • lotus miner markets' Dagstore is a component of the markets subsystem in lotus-miner. It is a sharded store to hold large IPLD graphs efficiently, packaged as location-transparent attachable CAR files and it replaces the former Badger staging blockstore. It is designed to provide high efficiency and throughput, and minimize resource utilization during deal-making operations.
      The dagstore also leverages the indexing features of CARv2 to enable plan CAR files to act as read and write blockstores, which are served as the direct medium for data exchanges in markets for both storage and retrieval deal making without requiring intermediate buffers.
    • In the future, lotus will leverage and interact with Dagstore a lot for new features and improvements for deal making, therefore, it's highly recommended to lotus users to go through Lotus Miner: About the markets dagstore thoroughly to learn more about Dagstore's conceptual overview, terminology, directory structure, configuration and so on.
    • Note:
      • When you first start your lotus-miner or market subsystem with this release, a one-time/first-time dagstore migration will be triggered which replaces the former Badger staging blockstore with dagstore. We highly recommend storage providers to read this section to learn more about what the process does, what to expect and how monitor it.
      • It is highly recommended to wait all ongoing data transfer to finish or cancel inbound storage deals that are still transferring, using the lotus-miner data-transfers cancel command before upgrade your market nodes. Reason being that the new dagstore changes attributes in the internal deal state objects, and the paths to the staging CARs where the deal data was being placed will be lost.
      • ‼️Having your dags initialized will become important in the near feature for you to provide a better storage and retrieval service. We'd suggest you to start [forced bulk initialization] soon if possible as this process places relatively high IP workload on your storage system and is better to be carried out gradually and over a longer timeframe. Read how to do properly perform a force bulk initialization here.
      • ⏮ Rollback Alert(from v1.11.2-rcX to any version lower): If a storages deal is initiated with M1/v1.11.2(-rcX) release, it needs to get to the StorageDealAwaitingPrecommit state before you can do a version rollback or the markets process may panic.
    • 💙 Special thanks to MinerX fellows for testing and providing valuable feedbacks for Dagstore in the past month!
  • 🌟🌟 rpcenc: Support reader redirect (filecoin-project/lotus#6952)
    • This allows market processes to send piece bytes directly to workers involved on AddPiece.
  • Extending sectors: more practical and flexible tools (filecoin-project/lotus#6097)
    • lotus-miner sectors check-expire to inspect expiring sectors.
    • lotus-miner sectors renew for renewing expiring sectors, see the command help menu for customizable option like extension, new-expiration and so on.
  • ‼️ MpoolReplaceCmd ( lotus mpool replace`) now takes FIL for fee-limit (filecoin-project/lotus#6927)
  • Drop townhall/chainwatch (filecoin-project/lotus#6912)
    • ChainWatch is no longer supported by lotus.
  • Configurable CC Sector Expiration (filecoin-project/lotus#6803)
    • Set CommittedCapacitySectorLifetime in lotus-miner/config.toml to specify the default expiration for a new CC sector, value must be between 180-540 days inclusive.

1.11.1 / 2021-08-16

Note: for discussion about this release, please comment here

This is a highly recommended but optional Lotus v1.11.1 release that introduces many deal making and datastore improvements and new features along with other bug fixes.

Highlights

  • ⭐️⭐️⭐️lotus-miner market subsystem is introduced in this release! It is highly recommended for storage providers to run markets processes on a separate machine! Doing so, only this machine needs to exposes public ports for deal making. This also means that the other miner operations can now be completely isolated by from the deal making processes and storage providers can stop and restarts the markets process without affecting an ongoing Winning/Window PoSt!
    • More details on the concepts, architecture and how to split the market process can be found here.
    • Base on your system setup(running on separate machines, same machine and so on), please see the suggested practice by community members here.
      • Note: if you are running lotus-worker on a different machine, you will need to set MARKETS_API_INFO for certain CLI to work properly. This will be improved by #7072.
    • Huge thanks to MinerX fellows for helping testing the implementation, reporting the issues so they were fixed by now and providing feedbacks to user docs in the past three weeks!
  • Config for collateral from miner available balance (filecoin-project/lotus#6629)
    • Better control your sector collateral payment by setting CollateralFromMinerBalance, AvailableBalanceBuffer and DisableCollateralFallback.
      • CollateralFromMinerBalance: whether to use available miner balance for sector collateral instead of sending it with each message, default is false.
      • AvailableBalanceBuffer: minimum available balance to keep in the miner actor before sending it with messages, default is 0FIL.
      • DisableCollateralFallback: whether to send collateral with messages even if there is no available balance in the miner actor, default is false.
  • Config for deal publishing control addresses (filecoin-project/lotus#6697)
    • Set DealPublishControl to set the wallet used for sending PublishStorageDeals messages, instructions here.
  • Config UX improvements (filecoin-project/lotus#6848)
    • You can now preview the the default and updated node config by running lotus/lotus-miner config default/updated

1.10.1 / 2021-07-05

This is an optional but highly recommended release of Lotus for lotus miners that has many bug fixes and improvements based on the feedback we got from the community since HyperDrive.

New Features

  • commit batch: AggregateAboveBaseFee config #6650
    • AggregateAboveBaseFee is added to miner sealing configuration for setting the network base fee to start aggregating proofs. When the network base fee is lower than this value, the prove commits will be submitted individually via ProveCommitSector. According to the Batch Incentive Alignment introduced in FIP-0013, we recommend miners to set this value to 0.15 nanoFIL(which is the default value) to avoid unexpected aggregation fee in burn and enjoy the most benefits of aggregation!

Bug Fixes

  • storage: Fix FinalizeSector with sectors in storage paths #6652
  • Fix tiny error in check-client-datacap #6664
  • Fix: precommit_batch method used the wrong cfg.PreCommitBatchWait #6658
  • to optimize the batchwait #6636
  • fix getTicket: sector precommitted but expired case #6635
  • handleSubmitCommitAggregate() exception handling #6595
  • remove precommit check in handleCommitFailed #6634
  • ensure agg fee is adequate
  • fix: miner balance is not enough, so that ProveCommitAggregate msg exec failed #6623
  • commit batch: Initialize the FailedSectors map #6647

1.10.0 / 2021-06-23

This is a mandatory release of Lotus that introduces Filecoin network v13, codenamed the HyperDrive upgrade. The Filecoin mainnet will upgrade, which is epoch 892800, on 2021-06-30T22:00:00Z. The network upgrade introduces the following FIPs:

  • FIP-0008: Add miner batched sector pre-commit method
  • FIP-0011: Remove reward auction from reporting consensus faults
  • FIP-0012: DataCap Top up for FIL+ Client Addresses
  • FIP-0013: Add ProveCommitSectorAggregated method to reduce on-chain congestion
  • FIP-0015: Revert FIP-0009(Exempt Window PoSts from BaseFee burn)

Note that this release is built on top of Lotus v1.9.0. Enterprising users can use the master branch of Lotus to get the latest functionality, including all changes in this release candidate.

Proof batching and aggregation

FIPs 0008 and 0013 combine to allow for a significant increase in the rate of onboarding storage on the Filecoin network. This aims to lead to more useful data being stored on the network, reduced network congestion, and lower network base fee.

Check out the documentation [here]((https://lotus.filecoin.io/storage-providers/advanced-configurations/sealing/#precommitsectorsbatch) for details on the new Lotus miner sealing config options, here for fee config options, and explanations of the new features.

Note:

  • We recommend to keep PreCommitSectorsBatch as 1.
  • We recommend miners to set PreCommitBatchWait lower than 30 hours.
  • We recommend miners to set a longer CommitBatchSlack and PreCommitBatchSlack to prevent message failures due to expirations.

Projected state tree growth

In order to validate the Hyperdrive changes, we wrote a simulation to seal as many sectors as quickly as possible, assuming the same number and mix of 32GiB and 64GiB miners as the current network.

Given these assumptions:

  • We'd expect a network storage growth rate of around 530PiB per day. 😳 🎉 🥳 😅
  • We'd expect network bandwidth dedicated to SubmitWindowedPoSt to grow by about 0.02% per day.
  • We'd expect the state-tree (and therefore snapshot) size to grow by 1.16GiB per day.
    • Nearly all of the state-tree growth is expected to come from new sector metadata.
  • We'd expect the daily lotus datastore growth rate to increase by about 10-15% (from current ~21GiB/day).
    • Most "growth" of the lotus datastore is due to "churn", historical data that's no longer referenced by the latest state-tree.

Future improvements

Various Lotus improvements are planned moving forward to mitigate the effects of the growing state tree size. The primary improvement is the Lotus splitstore, which will soon be enabled by default. The feature allows for online garbage collection for nodes that do not seek to maintain full chain and state history, thus eliminating the need for users to delete their datastores and sync from snapshots.

Other improvements including better compressed snapshots, faster pre-migrations, and improved chain exports are in the roadmap.

WindowPost base fee burn

Included in the HyperDrive upgrade is FIP-0015 which eliminates the special-case gas treatment of SubmitWindowedPoSt messages that was introduced in FIP-0009. Although SubmitWindowedPoSt messages will be relatively cheap, thanks to the introduction of optimistic acceptance of these proofs in FIP-0010, storage providers should pay attention to their MaxWindowPoStGasFee config option: too low and PoSts may not land on chain; too high and they may cost an exorbitant amount!

1.9.0 / 2021-05-17

This is an optional Lotus release that introduces various improvements to the sealing, mining, and deal-making processes.

Highlights

Changes

Fixes

1.8.0 / 2021-04-05

This is a mandatory release of Lotus that upgrades the network to version 12, which introduces various performance improvements to the cron processing of the power actor. The network will upgrade at height 712320, which is 2021-04-29T06:00:00Z.

Changes

1.6.0 / 2021-04-05

This is a mandatory release of Lotus that upgrades the network to version 11, which implements FIP-0014. The network will upgrade at height 665280, which is 2021-04-12T22:00:00Z.

v1 sector extension CLI

This release also expands the lotus-miner sectors extend CLI, with a new option that automatically extends all extensible v1 sectors. The option can be run using lotus-miner sectors extend --v1-sectors.

  • The tolerance flag can be passed to indicate what durations aren't "worth" extending. It defaults to one week, which means that sectors whose current lifetime's are within one week of the maximum possible lifetime will not be extended.

  • The expiration-cutoff flag can be passed to skip sectors whose expiration is past a certain point from the current head. It defaults to infinity (no cutoff), but if, say, 28800 was specified, then only sectors expiring in the next 10 days would be extended (2880 epochs in 1 day).

Changes

1.5.3 / 2021-03-24

This is a patch release of Lotus that introduces small fixes to the Storage FSM.

Changes

1.5.2 / 2021-03-11

This is an hotfix release of Lotus that fixes a critical bug introduced in v1.5.1 in the miner windowPoSt logic. This upgrade is only affecting miner nodes.

Changes

1.5.1 / 2021-03-10

This is an optional release of Lotus that introduces an important fix to the WindowPoSt computation process. The change is to wait for some confidence before drawing beacon randomness for the proof. Without this, invalid proofs might be generated as the result of a null tipset.

Splitstore

This release also introduces the splitstore, a new optional blockstore that segregates the monolithic blockstore into cold and hot regions. The hot region contains objects from the last 4-5 finalities plus all reachable objects from two finalities away. All other objects are moved to the cold region using a compaction process that executes every finality, once 5 finalities have elapsed.

The splitstore allows us to separate the two regions quite effectively, using two separate badger blockstores. The separation means that the live working set is much smaller, which results in potentially significant performance improvements. In addition, it means that the coldstore can be moved to a separate (bigger, slower, cheaper) disk without loss of performance.

The design also allows us to use different implementations for the two blockstores; for example, an append-only blockstore could be used for coldstore and a faster memory mapped blockstore could be used for the hotstore (eg LMDB). We plan to experiment with these options in the future.

Once the splitstore has been enabled, the existing monolithic blockstore becomes the coldstore. On the first head change notification, the splitstore will warm up the hotstore by copying all reachable objects from the current tipset into the hotstore. All new writes go into the hotstore, with the splitstore tracking the write epoch. Once 5 finalities have elapsed, and every finality thereafter, the splitstore compacts by moving cold objects into the coldstore. There is also experimental support for garbage collection, whereby nunreachable objects are simply discarded.

To enable the splitstore, add the following to config.toml:

[Chainstore]
  EnableSplitstore = true

Highlights

Other highlights include:

  • Improved deal data handling - now multiple deals can be adding to sectors in parallel
  • Rewriten sector pledging - it now actually cares about max sealing sector limits
  • Better handling for sectors stuck in the RecoverDealIDs state
  • lotus-miner sectors extend command
  • Optional configurable storage path size limit
  • Config to disable owner/worker fallback from control addresses (useful when owner is a key on a hardware wallet)
  • A write log for node metadata, which can be restored as a backup when the metadata leveldb becomes corrupted (e.g. when you run out of disk space / system crashes in some bad way)

Changes

1.5.0 / 2021-02-23

This is a mandatory release of Lotus that introduces the fifth upgrade to the Filecoin network. The network upgrade occurs at height 550321, before which time all nodes must have updated to this release (or later). At this height, v3 specs-actors will take effect, which in turn implements the following two FIPs:

  • FIP-0007 h/amt-v3 which improves the performance of the Filecoin HAMT and AMT.
  • FIP-0010 off-chain Window PoSt Verification which reduces the gas consumption of SubmitWindowedPoSt messages significantly by optimistically accepting Window PoSt proofs without verification, and allowing them to be disputed later by off-chain verifiers.

Note that the integration of v3 actors was already completed in 1.4.2, this upgrade simply sets the epoch for the upgrade to occur.

Disputer

FIP-0010 introduces the ability to dispute bad Window PoSts. Node operators are encouraged to run the new Lotus disputer alongside their Lotus daemons. For more information, see the announcement here.

Changes

  • #5341 Add a LOTUS_DISABLE_V3_ACTOR_MIGRATION envvar
    • Setting this envvar to 1 disables the v3 actor migration, should only be used in the event of a failed migration

1.4.2 / 2021-02-17

This is a large, and highly recommended, optional release with new features and improvements for lotus miner and deal-making UX. The release also integrates v3 specs-actors, which implements two FIPs:

  • FIP-0007 h/amt-v3 which improves the performance of the Filecoin HAMT and AMT.
  • FIP-0010 off-chain Window PoSt Verification which reduces the gas consumption of SubmitWindowedPoSt messages significantly by optimistically accepting Window PoSt proofs without verification, and allowing them to be disputed later by off-chain verifiers.

Note that this release does NOT set an upgrade epoch for v3 actors to take effect. That will be done in the upcoming 1.5.0 release.

1.1.2 / 2020-10-24

This is a patch release of Lotus that builds on the fixes involving worker keys that was introduced in v1.1.1. Miners and node operators should update to this release as soon as possible in order to ensure their blocks are propagated and validated.

Changes

1.1.1 / 2020-10-24

This is a patch release of Lotus that addresses some issues caused by when miners change their worker keys. Miners and node operators should update to this release as soon as possible, especially any miner who has changed their worker key recently.

Changes

1.1.0 / 2020-10-20

This is a mandatory release that introduces the first post-liftoff upgrade to the Filecoin network. The changes that break consensus are an upgrade to specs-actors v2.2.0 at epoch 170000.

Changes

1.0.0 / 2020-10-19

It's 1.0.0! This is an optional release of Lotus that introduces some UX improvements to the 0.10 series.

This very small release is largely cosmetic, and intended to flag the code that the Filecoin mainnet was launched with.

API changes

  • StateMsgGasCost has been removed. The equivalent information can be gained by calling StateReplay.
  • A GasCost field has been added to the InvocResult type, meaning detailed gas costs will be returned when calling StateReplay, StateCompute, and StateCall.
  • The behaviour of StateReplay in response to an empty tipset key has been changed. Instead of simply using the heaviest tipset (which is almost guaranteed to be an unsuccessful replay), we search now search the chain for the tipset that included the message, and replay the message in that tipset (we fail if no such tipset is found).

Changes

0.10.2 / 2020-10-14

This is an optional release of Lotus that updates markets to 0.9.1, which fixes an issue affecting deals that were mid-transfer when the node was upgraded to 0.9.0. This release also includes some tweaks to default gas values and minor performance improvements.

Changes

0.10.1 / 2020-10-14

This is an optional release of Lotus that updates markets to 0.9.0, which adds the ability to restart data transfers. This release also introduces Ledger support, and various UX improvements.

Changes

0.10.0 / 2020-10-12

This is a consensus-breaking hotfix that addresses an issue in specs-actors v2.0.3 that made it impossible to pledge new 32GiB sectors. The change in Lotus is to update to actors v2.1.0, behind the new network version 5.

Changes

0.9.1 / 2020-10-10

This release fixes an issue which may cause the actors v2 migration to compute the state incorrectly when more than one migration is running in parallel.

Changes

0.9.0 / 2020-10-07

This consensus-breaking release of Lotus upgrades the actors version to v2.0.0. This requires migrating actor state from v0 to v2. The changes that break consensus are:

Changes

0.5.9 / 2020-09-03

This patch includes a hotfix to the GasEstimateFeeCap method, capping the estimated fee to a reasonable level by default.

Changes

0.5.8 / 2020-09-02

Changes

0.5.7 / 2020-08-31

This patch release includes some bugfixes and enhancements to the sector lifecycle and message pool logic.

Changes

0.5.6 / 2020-08-29

Hotfix release that fixes a panic in the sealing scheduler (https://github.com/filecoin-project/lotus/pull/3389).

0.5.5

This patch release introduces a large number of improvements to the sealing process. It also updates go-fil-markets to version 0.5.8, and go-libp2p-pubsub to v0.3.5.

Downstream upgrades

Sector sealing

  • The following improvements were introduced in https://github.com/filecoin-project/lotus/pull/3350.

    • Allow lotus-miner sectors remove to remove a sector in any state.
    • Create a separate state in the storage FSM dedicated to submitting the Commit message.
    • Recovery for when the Deal IDs of deals in a sector get changed in a reorg.
    • Auto-retry sending Precommit and Commit messages if they run out of gas
    • Auto-retry sector remove tasks when they fail
    • Compact worker windows, and allow their tasks to be executed in any order

  • Don't simply skip PoSt for bad sectors (https://github.com/filecoin-project/lotus/pull/3323)

Message Pool

Chainwatch

0.5.4

A patch release, containing a few nice bugfixes and improvements:

  • Fix parsing of peer ID in lotus-miner actor set-peer-id (@whyrusleeping)
  • Update dependencies, fixing several bugs (@Stebalien)
  • Fix remaining linter warnings (@Stebalien)
  • Use safe string truncation (@Ingar)
  • Allow tweaking of blocksync message window size (@whyrusleeping)
  • Add some additional gas stats to metrics (@Kubuxu)
  • Fix an edge case bug in message selection, add many tests (@vyzo)

0.5.3

Yet another hotfix release. A lesson for readers, having people who have been awake for 12+ hours review your hotfix PR is not a good idea. Find someone who has enough slept recently enough to give you good code review, otherwise you'll end up quickly bumping versions again.

  • Fixed a bug in the mempool that was introduced in v0.5.2

0.5.2 / 2020-08-24

This is a hotfix release.

  • Fix message selection to not include messages that are invalid for block inclusion.
  • Improve SelectMessage handling of the case where the message pools tipset differs from our mining base.

0.5.1 / 2020-08-24

The Space Race release! This release contains the genesis car file and bootstrap peers for the space race network.

Additionally, we included two small fixes to genesis creation:

  • Randomize ticket value in genesis generation
  • Correctly set t099 (burnt funds actor) to have valid account actor state

0.5.0 / 2020-08-20

This version of Lotus will be used for the incentivized testnet Space Race competition, and can be considered mainnet-ready code. It includes some protocol changes, upgrades of core dependencies, and various bugfixes and UX/performance improvements.

Highlights

Among the highlights included in this release are:

  • Gas changes: We implemented EIP-1559 and introduced real gas values.
  • Deal-making: We now support "Committed Capacity" sectors, "fast-retrieval" deals, and the packing of multiple deals into a single sector.
  • Renamed features: We renamed some of the binaries, environment variables, and default paths associated with a Lotus node.

Gas changes

We made some significant changes to the mechanics of gas in this release.

Network fee

We implemented something similar to Ethereum's EIP-1559. The Message structure had three changes:

  • The GasPrice field has been removed
  • A new GasFeeCap field has been added, which controls the maximum cost the sender incurs for the message
  • A new GasPremium field has been added, which controls the reward a miner earns for including the message

A sender will never be charged more than GasFeeCap * GasLimit. A miner will typically earn GasPremium * GasLimit as a reward.

The Blockheader structure has one new field, called ParentBaseFee. Informally speaking,the ParentBaseFee is increased when blocks are densely packed with messages, and decreased otherwise.

The ParentBaseFee is used when calculating how much a sender burns when executing a message. Burning simply refers to sending attoFIL to a dedicated, unreachable account. A message causes ParentBaseFee * GasUsed attoFIL to be burnt.

Real gas values

This release also includes our first "real" gas costs for primitive operations. The costs were designed to account for both the time that message execution takes, as well as the space a message adds to the state tree.

Deal-making changes

There are three key changes to the deal-making process.

Committed Capacity sectors

Miners can now pledge "Committed Capacity" (CC) sectors, which are explicitly stated as containing junk data, and must not include any deals. Miners can do this to increase their storage power, and win block rewards from this pledged storage.

They can mark these sectors as "upgradable" with lotus-miner sectors mark-for-upgrade. If the miner receives and accepts one or more storage deals, the sector that includes those deals will replace the CC sector. This is intended to maximize the amount of useful storage on the Filecoin network.

Fast-retrieval deals

Clients can now include a fast-retrieval flag when proposing deals with storage miners. If set to true, the miner will include an extra copy of the deal data. This data can be quickly served in a retrieval deal, since it will not need to be unsealed.

Multiple deals per sector

Miners can now pack multiple deals into a single sector, so long as all the deals fit into the sector capacity. This should increase the packing efficiency of miners.

Renamed features

To improve the user experience, we updated several names to mainatin standard prefixing, and to better reflect the meaning of the features being referenced.

In particular, the Lotus miner binary is now called lotus-miner, the default path for miner data is now ~/.lotusminer, and the environment variable that sets the path for miner data is now $LOTUS_MINER_PATH. A full list of renamed features can be found here.
