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 -insecure -import-path ../proto -import-path ../proto-ethereum -proto dfuse/ethereum/codec/v1/codec.proto -proto dfuse/bstream/v1/bstream.proto -d '{"start_block_num": -1}' 127.0.0.1:13042 dfuse.bstream.v1.BlockStreamV2.Blocks

  Note You will need to have grpcurl and a clone of both https://github.com/streamingfast/proto and https://github.com/streamingfast/proto-ethereum, 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.
