Optimal Flexible Consensus (Confirmation Rule for Ethereum)

To reproduce the experiments with our proof-of-concept implementation of the flexible confirmation rule for Ethereum (derived from our optimal high-safety flexible consensus construction):

1. Setup and run an Ethereum full node (see instructions below, requires ~50 hours of time and ~4TB of NVMe SSD storage)
2. Setup and run the proof-of-concept implementation of the flexible confirmation rule for Ethereum (see instructions below)
3. Inspect output (see instructions below)

Setup of Ethereum Node

Lighthouse (Consensus Client)

Setup:

curl --proto '=https' --tlsv1.2 -sSf https://sh.rustup.rs | sh
sudo apt install -y git gcc g++ make cmake pkg-config llvm-dev libclang-dev clang protobuf-compiler
git clone https://github.com/sigp/lighthouse.git
cd lighthouse
git checkout dfcb3363c757671eb19d5f8e519b4b94ac74677a
PROFILE=maxperf make -j8

Run:

lighthouse bn --network mainnet --datadir /home/ubuntu/lighthouse-data --http --execution-endpoint http://localhost:8551 --execution-jwt /home/ubuntu/reth-data/jwt.hex --reconstruct-historic-states --slots-per-restore-point 256 --historic-state-cache-size 8 --checkpoint-sync-url https://mainnet.checkpoint.sigp.io --genesis-backfill --disable-backfill-rate-limiting

Reth (Execution Client)

Setup:

curl --proto '=https' --tlsv1.2 -sSf https://sh.rustup.rs | sh
sudo apt-get install libclang-dev pkg-config build-essential
git clone https://github.com/paradigmxyz/reth
cd reth
git checkout 77faa04ca6682c033ecfe391a0e5672692ba0adb
RUSTFLAGS="-C target-cpu=native" cargo install --profile maxperf --path bin/reth --bin reth

Run:

reth node --chain mainnet --datadir /home/ubuntu/reth-data --http --http.api all --authrpc.jwtsecret /home/ubuntu/reth-data/jwt.hex --authrpc.addr 127.0.0.1 --authrpc.port 8551

Foundry (Debugging)

Setup:

curl -L https://foundry.paradigm.xyz | bash
source /home/ubuntu/.bashrc
foundryup

Run:

cast rpc eth_syncing

Utils

Setup:

apt-get install ifstat htop tmux iotop vnstat net-tools

Confirmation Rule for Ethereum

cd flexible-eth/flexibleeth
./run-example.sh cache.rocksdb 2560

Output

After running the proof-of-concept implementation of the confirmation rule for Ethereum (see run-example.sh script), the output is found in output-example-....
