## VulcanizeDB Super Node APIs
|
||||
The super node exposes a number of different APIs for remote access to the underlying DB.
|
||||
|
||||
|
||||
### Table of Contents
|
||||
1. [Postgraphile](#postgraphile)
|
||||
1. [RPC Subscription Interface](#rpc-subscription-interface)
|
||||
1. [Native API Recapitulation](#native-api-recapitulation)
|
||||
|
||||
|
||||
### Postgraphile
|
||||
The super node stores all processed data in Postgres using PG-IPFS, this includes all of the IPLD objects.
|
||||
[Postgraphile](https://www.graphile.org/postgraphile/) can be used to expose GraphQL endpoints for the Postgres tables.
|
||||
|
||||
e.g.
|
||||
|
||||
`postgraphile --plugins @graphile/pg-pubsub --subscriptions --simple-subscriptions -c postgres://localhost:5432/vulcanize_public?sslmode=disable -s public,btc,eth -a -j`
|
||||
|
||||
|
||||
This will stand up a Postgraphile server on the public, eth, and btc schemas- exposing GraphQL endpoints for all of the tables contained under those schemas.
|
||||
All of their data can then be queried with standard [GraphQL](https://graphql.org) queries.
|
||||
|
||||
|
||||
### RPC Subscription Interface
|
||||
A direct, real-time subscription to the data being processed by the super node can be established over WS or IPC through the [Stream](../../pkg/super_node/api.go#L53) RPC method.
|
||||
This method is not chain-specific and each chain-type supports it, it is accessed under the "vdb" namespace rather than a chain-specific namespace. An interface for
|
||||
subscribing to this endpoint is provided [here](../../libraries/shared/streamer/super_node_streamer.go).
|
||||
|
||||
When subscribing to this endpoint, the subscriber provides a set of RLP-encoded subscription parameters. These parameters will be chain-specific, and are used
|
||||
by the super node to filter and return a requested subset of chain data to the subscriber. (e.g. [BTC](../../pkg/super_node/btc/subscription_config.go), [ETH](../../pkg/super_node/eth/subscription_config.go)).
|
||||
|
||||
#### Ethereum RPC Subscription
|
||||
An example of how to subscribe to a real-time Ethereum data feed from the super node using the `Stream` RPC method is provided below
|
||||
|
||||
```go
|
||||
package main
|
||||
|
||||
import (
|
||||
"github.com/ethereum/go-ethereum/rlp"
|
||||
"github.com/ethereum/go-ethereum/rpc"
|
||||
"github.com/spf13/viper"
|
||||
|
||||
"github.com/vulcanize/vulcanizedb/libraries/shared/streamer"
|
||||
"github.com/vulcanize/vulcanizedb/pkg/eth/client"
|
||||
"github.com/vulcanize/vulcanizedb/pkg/super_node"
|
||||
"github.com/vulcanize/vulcanizedb/pkg/super_node/eth"
|
||||
)
|
||||
|
||||
config, _ := eth.NewEthSubscriptionConfig()
|
||||
rlpConfig, _ := rlp.EncodeToBytes(config)
|
||||
vulcPath := viper.GetString("superNode.ethSubscription.path")
|
||||
rawRPCClient, _ := rpc.Dial(vulcPath)
|
||||
rpcClient := client.NewRPCClient(rawRPCClient, vulcPath)
|
||||
stream := streamer.NewSuperNodeStreamer(rpcClient)
|
||||
payloadChan := make(chan super_node.SubscriptionPayload, 20000)
|
||||
subscription, _ := stream.Stream(payloadChan, rlpConfig)
|
||||
for {
|
||||
select {
|
||||
case payload := <- payloadChan:
|
||||
// do something with the subscription payload
|
||||
case err := <- subscription.Err():
|
||||
// do something with the subscription error
|
||||
}
|
||||
}
|
||||
```
|
||||
|
||||
The .toml file being used to fill the Ethereum subscription config would look something like this:
|
||||
|
||||
```toml
|
||||
[superNode]
|
||||
[superNode.ethSubscription]
|
||||
historicalData = false
|
||||
historicalDataOnly = false
|
||||
startingBlock = 0
|
||||
endingBlock = 0
|
||||
wsPath = "ws://127.0.0.1:8080"
|
||||
[superNode.ethSubscription.headerFilter]
|
||||
off = false
|
||||
uncles = false
|
||||
[superNode.ethSubscription.txFilter]
|
||||
off = false
|
||||
src = []
|
||||
dst = []
|
||||
[superNode.ethSubscription.receiptFilter]
|
||||
off = false
|
||||
contracts = []
|
||||
topic0s = []
|
||||
topic1s = []
|
||||
topic2s = []
|
||||
topic3s = []
|
||||
[superNode.ethSubscription.stateFilter]
|
||||
off = false
|
||||
addresses = []
|
||||
intermediateNodes = false
|
||||
[superNode.ethSubscription.storageFilter]
|
||||
off = true
|
||||
addresses = []
|
||||
storageKeys = []
|
||||
intermediateNodes = false
|
||||
```
|
||||
|
||||
These configuration parameters are broken down as follows:
|
||||
|
||||
`ethSubscription.wsPath` is used to define the SuperNode ws url OR ipc endpoint we subscribe to
|
||||
|
||||
`ethSubscription.historicalData` specifies whether or not the super node should look up historical data in its cache and
|
||||
send that to the subscriber, if this is set to `false` then the super node only streams newly synced/incoming data
|
||||
|
||||
`ethSubscription.historicalDataOnly` will tell the super node to only send historical data with the specified range and
|
||||
not stream forward syncing data
|
||||
|
||||
`ethSubscription.startingBlock` is the starting block number for the range we want to receive data in
|
||||
|
||||
`ethSubscription.endingBlock` is the ending block number for the range we want to receive data in;
|
||||
setting to 0 means there is no end/we will continue streaming indefinitely.
|
||||
|
||||
`ethSubscription.headerFilter` has two sub-options: `off` and `uncles`.
|
||||
|
||||
- Setting `off` to true tells the super node to not send any headers to the subscriber
|
||||
- setting `uncles` to true tells the super node to send uncles in addition to normal headers.
|
||||
|
||||
`ethSubscription.txFilter` has three sub-options: `off`, `src`, and `dst`.
|
||||
|
||||
- Setting `off` to true tells the super node to not send any transactions to the subscriber
|
||||
- `src` and `dst` are string arrays which can be filled with ETH addresses we want to filter transactions for,
|
||||
if they have any addresses then the super node will only send transactions that were sent or received by the addresses contained
|
||||
in `src` and `dst`, respectively.
|
||||
|
||||
`ethSubscription.receiptFilter` has four sub-options: `off`, `topics`, `contracts` and `matchTxs`.
|
||||
|
||||
- Setting `off` to true tells the super node to not send any receipts to the subscriber
|
||||
- `topic0s` is a string array which can be filled with event topics we want to filter for,
|
||||
if it has any topics then the super node will only send receipts that contain logs which have that topic0.
|
||||
- `contracts` is a string array which can be filled with contract addresses we want to filter for, if it contains any contract addresses the super node will
|
||||
only send receipts that correspond to one of those contracts.
|
||||
- `matchTrxs` is a bool which when set to true any receipts that correspond to filtered for transactions will be sent by the super node, regardless of whether or not the receipt satisfies the `topics` or `contracts` filters.
|
||||
|
||||
`ethSubscription.stateFilter` has three sub-options: `off`, `addresses`, and `intermediateNodes`.
|
||||
|
||||
- Setting `off` to true tells the super node to not send any state data to the subscriber
|
||||
- `addresses` is a string array which can be filled with ETH addresses we want to filter state for,
|
||||
if it has any addresses then the super node will only send state leafs (accounts) corresponding to those account addresses.
|
||||
- By default the super node only sends along state leafs, if we want to receive branch and extension nodes as well `intermediateNodes` can be set to `true`.
|
||||
|
||||
`ethSubscription.storageFilter` has four sub-options: `off`, `addresses`, `storageKeys`, and `intermediateNodes`.
|
||||
|
||||
- Setting `off` to true tells the super node to not send any storage data to the subscriber
|
||||
- `addresses` is a string array which can be filled with ETH addresses we want to filter storage for,
|
||||
if it has any addresses then the super node will only send storage nodes from the storage tries at those state addresses.
|
||||
- `storageKeys` is another string array that can be filled with storage keys we want to filter storage data for. It is important to note that the storage keys need to be the actual keccak256 hashes, whereas
|
||||
the addresses in the `addresses` fields are pre-hashed ETH addresses.
|
||||
- By default the super node only sends along storage leafs, if we want to receive branch and extension nodes as well `intermediateNodes` can be set to `true`.
|
||||
|
||||
### Bitcoin RPC Subscription:
|
||||
An example of how to subscribe to a real-time Bitcoin data feed from the super node using the `Stream` RPC method is provided below
|
||||
|
||||
```go
|
||||
package main
|
||||
|
||||
import (
|
||||
"github.com/ethereum/go-ethereum/rlp"
|
||||
"github.com/ethereum/go-ethereum/rpc"
|
||||
"github.com/spf13/viper"
|
||||
|
||||
"github.com/vulcanize/vulcanizedb/libraries/shared/streamer"
|
||||
"github.com/vulcanize/vulcanizedb/pkg/eth/client"
|
||||
"github.com/vulcanize/vulcanizedb/pkg/super_node"
|
||||
"github.com/vulcanize/vulcanizedb/pkg/super_node/btc"
|
||||
)
|
||||
|
||||
config, _ := btc.NewBtcSubscriptionConfig()
|
||||
rlpConfig, _ := rlp.EncodeToBytes(config)
|
||||
vulcPath := viper.GetString("superNode.btcSubscription.path")
|
||||
rawRPCClient, _ := rpc.Dial(vulcPath)
|
||||
rpcClient := client.NewRPCClient(rawRPCClient, vulcPath)
|
||||
stream := streamer.NewSuperNodeStreamer(rpcClient)
|
||||
payloadChan := make(chan super_node.SubscriptionPayload, 20000)
|
||||
subscription, _ := stream.Stream(payloadChan, rlpConfig)
|
||||
for {
|
||||
select {
|
||||
case payload := <- payloadChan:
|
||||
// do something with the subscription payload
|
||||
case err := <- subscription.Err():
|
||||
// do something with the subscription error
|
||||
}
|
||||
}
|
||||
```
|
||||
|
||||
The .toml file being used to fill the Bitcoin subscription config would look something like this:
|
||||
|
||||
```toml
|
||||
[superNode]
|
||||
[superNode.btcSubscription]
|
||||
historicalData = false
|
||||
historicalDataOnly = false
|
||||
startingBlock = 0
|
||||
endingBlock = 0
|
||||
wsPath = "ws://127.0.0.1:8080"
|
||||
[superNode.btcSubscription.headerFilter]
|
||||
off = false
|
||||
[superNode.btcSubscription.txFilter]
|
||||
off = false
|
||||
segwit = false
|
||||
witnessHashes = []
|
||||
indexes = []
|
||||
pkScriptClass = []
|
||||
multiSig = false
|
||||
addresses = []
|
||||
```
|
||||
|
||||
These configuration parameters are broken down as follows:
|
||||
|
||||
`btcSubscription.wsPath` is used to define the SuperNode ws url OR ipc endpoint we subscribe to
|
||||
|
||||
`btcSubscription.historicalData` specifies whether or not the super node should look up historical data in its cache and
|
||||
send that to the subscriber, if this is set to `false` then the super node only streams newly synced/incoming data
|
||||
|
||||
`btcSubscription.historicalDataOnly` will tell the super node to only send historical data with the specified range and
|
||||
not stream forward syncing data
|
||||
|
||||
`btcSubscription.startingBlock` is the starting block number for the range we want to receive data in
|
||||
|
||||
`btcSubscription.endingBlock` is the ending block number for the range we want to receive data in;
|
||||
setting to 0 means there is no end/we will continue streaming indefinitely.
|
||||
|
||||
`btcSubscription.headerFilter` has one sub-option: `off`.
|
||||
|
||||
- Setting `off` to true tells the super node to
|
||||
not send any headers to the subscriber.
|
||||
- Additional header-filtering options will be added in the future.
|
||||
|
||||
`btcSubscription.txFilter` has seven sub-options: `off`, `segwit`, `witnessHashes`, `indexes`, `pkScriptClass`, `multiSig`, and `addresses`.
|
||||
|
||||
- Setting `off` to true tells the super node to not send any transactions to the subscriber.
|
||||
- Setting `segwit` to true tells the super node to only send segwit transactions.
|
||||
- `witnessHashes` is a string array that can be filled with witness hash string; if it contains any hashes the super node will only send transactions that contain one of those hashes.
|
||||
- `indexes` is an int64 array that can be filled with tx index numbers; if it contains any integers the super node will only send transactions at those indexes (e.g. `[0]` will send only coinbase transactions)
|
||||
- `pkScriptClass` is an uint8 array that can be filled with pk script class numbers; if it contains any integers the super node will only send transactions that have at least one tx output with one of the specified pkscript classes;
|
||||
possible class types are 0 through 8 as defined [here](https://github.com/btcsuite/btcd/blob/master/txscript/standard.go#L52).
|
||||
- Setting `multisig` to true tells the super node to send only multi-sig transactions- to send only transaction that have at least one tx output that requires more than one signature to spend.
|
||||
- `addresses` is a string array that can be filled with btc address strings; if it contains any addresses the super node will only send transactions that have at least one tx output with at least one of the provided addresses.
|
||||
|
||||
|
||||
### Native API Recapitulation:
|
||||
In addition to providing novel Postgraphile and RPC-Subscription endpoints, we are working towards complete recapitulation of the
|
||||
standard chain APIs. This will allow direct compatibility with software that already makes use of the standard interfaces.
|
||||
|
||||
#### Ethereum JSON-RPC API
|
||||
The super node currently faithfully recapitulates portions of the Ethereum JSON-RPC api standard.
|
||||
|
||||
The currently supported endpoints include:
|
||||
`eth_blockNumber`
|
||||
`eth_getLogs`
|
||||
`eth_getHeaderByNumber`
|
||||
`eth_getBlockByNumber`
|
||||
`eth_getBlockByHash`
|
||||
`eth_getTransactionByHash`
|
||||
|
||||
Additional endpoints will be added in the near future, with the immediate goal of recapitulating the largest set of "eth_" endpoints which can be provided as a service.
|
||||
|
||||
#### Bitcoin JSON-RPC API:
|
||||
In the near future, the standard Bitcoin JSON-RPC interfaces will be implemented.

# VulcanizeDB Super Node Architecture
|
||||
The VulcanizeDB super node is a collection of interfaces that are used to extract, process, and store in Postgres-IPFS
|
||||
all chain data. The raw data indexed by the super node serves as the basis for more specific watchers and applications.
|
||||
|
||||
Currently the service supports complete processing of all Bitcoin and Ethereum data.

|
||||
|
||||
|
||||
Appropriating the service for a new chain is done by creating underlying types to satisfy these interfaces for
|
||||
the specifics of that chain.
|
||||
|
||||
The service uses these interfaces to operate in any combination of three modes: sync, serve, and backfill.
|
||||
* Sync: Streams raw chain data at the head, converts and publishes it to IPFS, and indexes the resulting set of CIDs in Postgres with useful metadata.
|
||||
* BackFill: Automatically searches for and detects gaps in the DB; fetches, converts, publishes, and indexes the data to fill these gaps.
|
||||
* Serve: Opens up IPC, HTTP, and WebSocket servers on top of the superNode DB and any concurrent sync and/or backfill processes.
|
||||
|
||||
|
||||
These three modes are all operated through a single vulcanizeDB command: `superNode`
|
||||
|
||||
## Command
|
||||
|
||||
Usage: `./vulcanizedb superNode --config={config.toml}`
|
||||
|
||||
Configuration can also be done through CLI options and/or environmental variables.
|
||||
CLI options can be found using `./vulcanizedb superNode --help`.
|
||||
|
||||
## Config
|
||||
|
||||
Below is the set of universal config parameters for the superNode command, in .toml form, with the respective environmental variables commented to the side.
|
||||
This set of parameters needs to be set no matter the chain type.
|
||||
|

||||
timeout = 300 # $HTTP_TIMEOUT
|
||||
validationLevel = 1 # $SUPERNODE_VALIDATION_LEVEL
|
||||
```
|
||||
|
||||
Additional parameters need to be set depending on the specific chain.
|
||||
|
||||
For Bitcoin:
|
||||
|
||||
```toml
|
||||
[bitcoin]
|
||||
wsPath = "127.0.0.1:8332" # $BTC_WS_PATH

|
||||
networkID = "0xD9B4BEF9" # $BTC_NETWORK_ID
|
||||
```
|
||||
|
||||
For Ethereum:
|
||||
|
||||
```toml
|
||||
[ethereum]
|
||||
wsPath = "127.0.0.1:8546" # $ETH_WS_PATH
|
||||
httpPath = "127.0.0.1:8545" # $ETH_HTTP_PATH
|
||||
nodeID = "arch1" # $ETH_NODE_ID
|
||||
clientName = "Geth" # $ETH_CLIENT_NAME
|
||||
genesisBlock = "0xd4e56740f876aef8c010b86a40d5f56745a118d0906a34e69aec8c0db1cb8fa3" # $ETH_GENESIS_BLOCK
|
||||
networkID = "1" # $ETH_NETWORK_ID
|
||||
```
|
||||
|
||||
## Database
|
||||
|
||||
Currently, the super node persists all data to a single Postgres database. The migrations for this DB can be found [here](../../db/migrations).
|
||||
Chain-specific data is populated under a chain-specific schema (e.g. `eth` and `btc`) while shared data- such as the IPFS blocks table- is populated under the `public` schema.
|
||||
Subsequent watchers which act on the raw chain data should build and populate their own schemas or separate databases entirely.
|
||||
|
||||
In the future, we will be moving to a foreign table based architecture wherein a single db is used for shared data while each watcher uses
|
||||
its own database and accesses and acts on the shared data through foreign tables. Isolating watchers to their own databases will prevent complications and
|
||||
conflicts between watcher db migrations.
|
||||
|
||||
|
||||
## APIs
|
||||
|
||||
The super node provides mutliple types of APIs by which to interface with its data.
|
||||
More detailed information on the APIs can be found [here](apis.md).
|
||||
|
||||
## Resync
|
||||
|
||||
A separate command `resync` is available for directing the resyncing of data within specified ranges.
|
||||
This is useful if we want to re-validate a range of data using a new source or clean out bad/deprecated data.
|
||||
More detailed information on this command can be found [here](resync.md).
|
||||
|
||||
## IPFS Considerations
|
||||
|
||||
Currently, the IPLD Publisher and Fetcher use internalized IPFS processes which interface directly with a local IPFS repository.
|
||||
This circumvents the need to run a full IPFS daemon with a [go-ipld-eth](https://github.com/ipfs/go-ipld-eth) plugin, but can lead to issues
|
||||
with lock-contention on the IPFS repo if another IPFS process is configured and running at the same $IPFS_PATH. This also necessitates the need for
|
||||
a locally configured IPFS repository.
|
||||
|
||||
Once go-ipld-eth has been updated to work with a modern version of PG-IPFS, an additional option will be provided to direct
|
||||
all publishing and fetching of IPLD objects through a remote IPFS daemon.

## VulcanizeDB Super Node Resync
|
||||
The `resync` command is made available for directing the resyncing of super node data within specified ranges.
|
||||
It also contains a utility for cleaning out old data, and resetting the validation level of data.
|
||||
|
||||
### Rational
|
||||
|
||||
Manual resyncing of data is useful when we want to re-validate data within specific ranges using a new source.
|
||||
|
||||
Cleaning out data is useful when we need to remove bad/deprecated data or prepare for breaking changes to the db schemas.
|
||||
|
||||
Resetting the validation level of data is useful for designating ranges of data for resyncing by an ongoing super node
|
||||
backfill process.
|
||||
|
||||
### Command
|
||||
|
||||
Usage: `./vulcanizedb resync --config={config.toml}`
|
||||
|
||||
Configuration can also be done through CLI options and/or environmental variables.
|
||||
CLI options can be found using `./vulcanizedb resync --help`.

## Super Node Setup
|

# VulcanizeDB Super Node Setup
|
||||
Step-by-step instructions for manually setting up and running a VulcanizeDB super node.
|
||||
|
||||
Vulcanizedb can act as an index for chain data stored on IPFS through the use of the `superNode` command.
|
||||
Steps:
|
||||
1. [Postgres](#postgres)
|
||||
1. [Goose](#goose)
|
||||
1. [IPFS](#ipfs)
|
||||
1. [Blockchain](#blockchain)
|
||||
1. [VulcanizeDB](#vulcanizedb)
|
||||
|
||||
### Manual Setup
|
||||
### Postgres
|
||||
A postgresDB is needed to storing all of the data in the vulcanizedb system.
|
||||
Postgres is used as the backing datastore for IPFS, and is used to index the CIDs for all of the chain data stored on IPFS.
|
||||
Follow the guides [here](https://wiki.postgresql.org/wiki/Detailed_installation_guides) for setting up Postgres.
|
||||
|
||||
These commands work in conjunction with a [state-diffing full Geth node](https://github.com/vulcanize/go-ethereum/tree/statediffing)
|
||||
and IPFS.
|
||||
Once the Postgres server is running, we will need to make a database for vulcanizedb, e.g. `vulcanize_public`.
|
||||
|
||||
#### IPFS
|
||||
To start, download and install [IPFS](https://github.com/vulcanize/go-ipfs)
|
||||
`createdb vulcanize_public`
|
||||
|
||||
For running the automated tests, also create a database named `vulcanize_testing`.
|
||||
|
||||
`createdb vulcanize_testing`
|
||||
|
||||
### Goose
|
||||
We use [goose](https://github.com/pressly/goose) as our migration management tool. While it is not necessary to use `goose` for manual setup, it
|
||||
is required for running the automated tests.
|
||||
|
||||
|
||||
### IPFS
|
||||
We use IPFS to store IPLD objects for each type of data we extract from on chain.
|
||||
|
||||
To start, download and install [IPFS](https://github.com/vulcanize/go-ipfs):

||||
Note: other CLI options- statediff specific ones included- can be explored with `./geth help`
|

The default ws url is "127.0.0.1:8546" and the default http url is "127.0.0.1:8545".
|
||||
These values will be used as the `ethereum.wsPath` and `ethereum.httpPath` in the super node config, respectively.
|
||||
|
||||
#### Vulcanizedb
|
||||
#### Bitcoin
|
||||
For Bitcoin, the super node is able to operate entirely through the universally exposed JSON-RPC interfaces.
|
||||
This means we can use any of the standard full nodes (e.g. bitcoind, btcd) as our data source.
|
||||
|
||||
The `superNode` command is used to initialize and run an instance of the VulcanizeDB SuperNode
|
||||
Point at a remote node or set one up locally using the instructions for [bitcoind](https://github.com/bitcoin/bitcoin) and [btcd](https://github.com/btcsuite/btcd).
|
||||
|
||||
Usage:
|
||||
The default http url is "127.0.0.1:8332". We will use the http endpoint as both the `bitcoin.wsPath` and `bitcoin.httpPath`
|
||||
(bitcoind does not support websocket endpoints, we are currently using a "subscription" wrapper around the http endpoints)
|
||||
|
||||
### Vulcanizedb
|
||||
Finally, we can begin the vulcanizeDB process itself.
|
||||
|
||||
Start by downloading vulcanizedb and moving into the repo:
|
||||
|
||||
`go get github.com/vulcanize/vulcanizedb`
|
||||
|
||||
`cd $GOPATH/src/github.com/vulcanize/vulcanizedb`
|
||||
|
||||
Run the db migrations against the Postgres database we created for vulcanizeDB:
|
||||
|
||||
`goose -dir=./db/migrations postgres postgres://localhost:5432/vulcanize_public?sslmode=disable up`
|
||||
|
||||
At this point, if we want to run the automated tests:
|
||||
|
||||
`make test`
|
||||
`make integration_test`
|
||||
|
||||
Then, build the vulcanizedb binary:
|
||||
|
||||
`go build`
|
||||
|
||||
And run the super node command with a provided [config](architecture.md/#):
|
||||
|
||||
`./vulcanizedb superNode --config=<config_file.toml`
|
||||
|
||||
|
||||
The config file contains the parameters needed to initialize a super node with the appropriate chain(s), settings, and services

### Dockerfile Setup
|
||||
|
||||
The below provides step-by-step directions for how to setup the super node using the provided Dockerfile on an AWS Linux AMI instance.
|
||||
Note that the instance will need sufficient memory and storage for this to work.
|
||||
|
||||
1. Install basic dependencies
|
||||
```
|
||||
sudo yum update
|
||||
sudo yum install -y curl gpg gcc gcc-c++ make git
|
||||
```
|
||||
|
||||
2. Install Go 1.12
|
||||
```
|
||||
wget https://dl.google.com/go/go1.12.6.linux-amd64.tar.gz
|
||||
tar -xzf go1.12.6.linux-amd64.tar.gz
|
||||
sudo mv go /usr/local
|
||||
```
|
||||
|
||||
3. Edit .bash_profile to export GOPATH
|
||||
```
|
||||
export GOROOT=/usr/local/go
|
||||
export GOPATH=$HOME/go
|
||||
export PATH=$GOPATH/bin:$GOROOT/bin:$PATH
|
||||
```
|
||||
|
||||
4. Install and setup Postgres
|
||||
```
|
||||
sudo yum install postgresql postgresql96-server
|
||||
sudo service postgresql96 initdb
|
||||
sudo service postgresql96 start
|
||||
sudo -u postgres createuser -s ec2-user
|
||||
sudo -u postgres createdb ec2-user
|
||||
sudo su postgres
|
||||
psql
|
||||
ALTER USER "ec2-user" WITH SUPERUSER;
|
||||
\q
|
||||
exit
|
||||
```
|
||||
|
||||
4b. Edit hba_file to trust local connections
|
||||
```
|
||||
psql
|
||||
SHOW hba_file;
|
||||
/q
|
||||
sudo vim {PATH_TO_FILE}
|
||||
```
|
||||
|
||||
4c. Stop and restart Postgres server to affect changes
|
||||
```
|
||||
sudo service postgresql96 stop
|
||||
sudo service postgresql96 start
|
||||
```
|
||||
|
||||
5. Install and start Docker (exit and re-enter ec2 instance afterwards to affect changes)
|
||||
```
|
||||
sudo yum install -y docker
|
||||
sudo service docker start
|
||||
sudo usermod -aG docker ec2-user
|
||||
```
|
||||
|
||||
6. Fetch the repository
|
||||
```
|
||||
go get github.com/vulcanize/vulcanizedb
|
||||
cd $GOPATH/src/github.com/vulcanize/vulcanizedb
|
||||
```
|
||||
|
||||
7. Create the db
|
||||
```
|
||||
createdb vulcanize_public
|
||||
```
|
||||
|
||||
8. Build and run the Docker image
|
||||
```
|
||||
cd $GOPATH/src/github.com/vulcanize/vulcanizedb/dockerfiles/super_node
|
||||
docker build --build-arg CONFIG_FILE=environments/superNode.toml --build-arg EXPOSE_PORT_1=8080 --build-arg EXPOSE_PORT_2=8081 EXPOSE_PORT_3=8082 --build-arg EXPOSE_PORT_4=8083 .
|
||||
docker run --network host -e IPFS_INIT=true -e VDB_PG_NAME=vulcanize_public -e VDB_PG_HOSTNAME=localhost -e VDB_PG_PORT=5432 -e VDB_PG_USER=postgres -e VDB_PG_PASSWORD=password {IMAGE_ID}

## SuperNode Subscription
|
||||
|
||||
A transformer can subscribe to the SueprNode service over its ipc or ws endpoints, when subscribing the transformer
|
||||
specifies the chain and a set of parameters which define which subsets of that chain's data the server should feed to them.
|
||||
|
||||
### Ethereum data
|
||||
The `streamEthSubscribe` command serves as a simple demonstration/example of subscribing to the super-node Ethereum feed, it subscribes with a set of parameters
|
||||
defined in the loaded config file, and prints the streamed data to stdout. To build transformers that subscribe to and use super-node Ethereum data,
|
||||
the shared/libraries/streamer can be used.
|
||||
|
||||
Usage:
|
||||
|
||||
`./vulcanizedb streamEthSubscribe --config=<config_file.toml>`
|
||||
|
||||
The config for `streamEthSubscribe` has a set of parameters to fill the [EthSubscription config structure](../../pkg/super_node/config/eth_subscription.go)
|
||||
|
||||
```toml
|
||||
[superNode]
|
||||
[superNode.ethSubscription]
|
||||
historicalData = false
|
||||
historicalDataOnly = false
|
||||
startingBlock = 0
|
||||
endingBlock = 0
|
||||
wsPath = "ws://127.0.0.1:8080"
|
||||

|
||||

|
||||

||||

|
||||

|
||||

|
||||
off = false
|
||||
contracts = []
|
||||
topic0s = []
|
||||
topic1s = []
|
||||
topic2s = []
|
||||
topic3s = []
|
||||
[superNode.ethSubscription.stateFilter]
|
||||
off = false
|
||||
addresses = []
|
||||
intermediateNodes = false
|
||||
[superNode.ethSubscription.storageFilter]
|
||||
off = true
|
||||
addresses = []
|
||||
storageKeys = []
|
||||
intermediateNodes = false
|
||||
```
|
||||
|
||||
`ethSubscription.path` is used to define the SuperNode ws url OR ipc endpoint we subscribe to
|
||||
|
||||
`ethSubscription.historicalData` specifies whether or not the super-node should look up historical data in its cache and
|
||||
send that to the subscriber, if this is set to `false` then the super-node only streams newly synced/incoming data
|
||||
|
||||
`ethSubscription.historicalDataOnly` will tell the super-node to only send historical data with the specified range and
|
||||
not stream forward syncing data
|
||||
|
||||
`ethSubscription.startingBlock` is the starting block number for the range we want to receive data in
|
||||
|
||||
`ethSubscription.endingBlock` is the ending block number for the range we want to receive data in;
|
||||
setting to 0 means there is no end/we will continue streaming indefinitely.
|
||||
|
||||
`ethSubscription.headerFilter` has two sub-options: `off` and `uncles`. Setting `off` to true tells the super-node to
|
||||
not send any headers to the subscriber; setting `uncles` to true tells the super-node to send uncles in addition to normal headers.
|
||||
|
||||
`ethSubscription.txFilter` has three sub-options: `off`, `src`, and `dst`. Setting `off` to true tells the super-node to
|
||||
not send any transactions to the subscriber; `src` and `dst` are string arrays which can be filled with ETH addresses we want to filter transactions for,
|
||||
if they have any addresses then the super-node will only send transactions that were sent or received by the addresses contained
|
||||
in `src` and `dst`, respectively.
|
||||
|
||||
`ethSubscription.receiptFilter` has four sub-options: `off`, `topics`, `contracts` and `matchTxs`. Setting `off` to true tells the super-node to
|
||||
not send any receipts to the subscriber; `topic0s` is a string array which can be filled with event topics we want to filter for,
|
||||
if it has any topics then the super-node will only send receipts that contain logs which have that topic0. Similarly, `contracts` is
|
||||
a string array which can be filled with contract addresses we want to filter for, if it contains any contract addresses the super-node will
|
||||
only send receipts that correspond to one of those contracts. `matchTrxs` is a bool which when set to true any receipts that correspond to filtered for
|
||||
transactions will be sent by the super-node, regardless of whether or not the receipt satisfies the `topics` or `contracts` filters.
|
||||
|
||||
`ethSubscription.stateFilter` has three sub-options: `off`, `addresses`, and `intermediateNodes`. Setting `off` to true tells the super-node to
|
||||
not send any state data to the subscriber; `addresses` is a string array which can be filled with ETH addresses we want to filter state for,
|
||||
if it has any addresses then the super-node will only send state leafs (accounts) corresponding to those account addresses. By default the super-node
|
||||
only sends along state leafs, if we want to receive branch and extension nodes as well `intermediateNodes` can be set to `true`.
|
||||
|
||||
`ethSubscription.storageFilter` has four sub-options: `off`, `addresses`, `storageKeys`, and `intermediateNodes`. Setting `off` to true tells the super-node to
|
||||
not send any storage data to the subscriber; `addresses` is a string array which can be filled with ETH addresses we want to filter storage for,
|
||||
if it has any addresses then the super-node will only send storage nodes from the storage tries at those state addresses. `storageKeys` is another string
|
||||
array that can be filled with storage keys we want to filter storage data for. It is important to note that the storageKeys are the actual keccak256 hashes, whereas
|
||||
the addresses in the `addresses` fields are the ETH addresses and not their keccak256 hashes that serve as the actual state keys. By default the super-node
|
||||
only sends along storage leafs, if we want to receive branch and extension nodes as well `intermediateNodes` can be set to `true`.
