Ethereum on StreamingFast

Requirements (clone repos, build stuff...)

Install Geth

git clone git@github.com:streamingfast/go-ethereum.git
cd go-ethereum
git checkout release/geth-1.10.x-dm
go install ./cmd/geth
go install ./cmd/bootnode

Install sfeth

git clone git@github.com:streamingfast/sf-ethereum.git
cd sf-ethereum
go install ./cmd/sfeth

Quickstart, connecting to an existing chain

Start from a clean folder

Create a file named sf.yaml and put the following content:

start:
args:
- merger
- firehose
- mindreader-node
- relayer
flags:
  common-chain-id: "1"
  common-network-id: "1"
  mindreader-node-bootstrap-data-url: ./mindreader/genesis.json
  mindreader-node-log-to-zap: false
  mindreader-node-arguments: "+--bootnodes=enode://<enode1>@<ip>:<port>,enode://<enode2>@<ip>:<port>"

Note Up to date boot nodes info for Geth supported network(s) can be found here.

Create a folder mindreader
Copy the genesis.json file of the chain into the mindreader folder.

Note It's possible to use geth dumpgenesis to dump actual genesis file to disk
- Mainnet - geth --mainnet dumpgenesis > ./mindreader/genesis.json
- Ropsten - geth --ropsten dumpgenesis > ./mindreader/genesis.json
- Goerli - geth --goerli dumpgenesis > ./mindreader/genesis.json
- Rinkeby - geth --rinkeby dumpgenesis > ./mindreader/genesis.json
sfeth start -vv

Note It's recommended to launch with -vv the first time to more easily see what's happening under the hood.
Wait around a minute leaving enough time for the Geth process to start the syncing process. You should then have some merged blocks under ./sf-data/storage/merged-blocks. You should also be able to test that Firehose is able to stream some blocks to you.

`grpcurl -plaintext -import-path ../proto -import-path ./proto -proto sf/ethereum/type/v1/type.proto -proto sf/firehose/v1/firehose.proto -d '{"start_block_num": -1}' localhost:13042 sf.firehose.v1.Stream.Blocks"

Note You will need to have grpcurl and a clone of https://github.com/streamingfast/proto, we assume they are sibling of the folder you are currently in, adjust -import-path ... flags in the command above to where the files are located.

Release

Use the ./bin/release.sh Bash script to perform a new release. It will ask you questions as well as driving all the required commands, performing the necessary operation automatically. The Bash script runs in dry-mode by default, so you can check first that everything is all right.

Releases are performed using goreleaser.
