v1.13.1-rc2 / 2021-11-02

This is the second release candidate for lotus optional release v1.13.1. More detailed changelog will be updated later.

For release related questions, leave a comment at https://github.com/filecoin-project/lotus/issues/7567.

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

  • 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 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

0.5.6 / 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.
