Run a proof of stake network on Deneb fork (Geth 1.14.6 and Prysm 5.0.4)

  1. Run this script./run-network.sh

This uses two validators - you can edit that number in both scripts.

Notes

  • The Prysm docs for running a Proof of Stake Devnet are out of date.
    • You need to add ELECTRA_FORK_VERSION: 0x20000094 to your config.yml
    • The genesis.json provided doesn't work with the deneb fork, so use the one given in this repo.
  • You need to start from the genesis-initial.json which is why we copy it into genesis.json as it is overwritten on each run.
  • The order of arguments for generating prysm genesis.ssz is extremely specific.
  • The geth, prysm and validator clients must be run from the same script to work and in the specific order. Discord thread here
  • Geth takes ~6 minutes to get past the Nil finalized block cannot evict old blobs errors.
  • Executables were compiled using the following commands and then deleting the source code:
git clone https://github.com/prysmaticlabs/prysm && cd prysm
go build -o=../beacon-chain ./cmd/beacon-chain
go build -o=../validator ./cmd/validator
go build -o=../prysmctl ./cmd/prysmctl
cd ..
git clone https://github.com/ethereum/go-ethereum && cd go-ethereum
make geth
cp ./build/bin/geth ../geth
cd ..

Errors

Hit these countless times trying to get this to work.
