Ethereum I — mainnet node package

Everything you need to run a node on the Ethereum I network and sync the chain from genesis. Clone it, run one command, and you're a peer.

Ethereum I is a custom Proof-of-Work EVM blockchain. The node software is CoreGeth (unmodified) plus this network's genesis and bootnode configuration.

Chain parameters

Network / Chain ID	588588
Consensus	Proof-of-Work, Ethash (ETChash family, pre-ECIP-1099, epoch length 30000)
Block reward	5.0 ETH1
Block gas limit	30,000,000
Currency symbol	ETH1 (18 decimals)
All EIPs active at	block 0
Genesis hash	0x10c89ff29f807c01de526209dbdb541d4e00390d5076fdf53b6e49f7d923275a
Client	CoreGeth v1.12.23 (commit 10f1ea745)

Public infrastructure

Service	URL
JSON-RPC	https://rpc.ethereum1.org
Block explorer	https://explorer.ethereum1.org
Network stats	https://stats.ethereum1.org

Public bootnode (discovery anchor):

enode://6ec5f44befef4af2155caf82205bdab46677c64457bbbb95758ca50407352c19d7b611352ff8151ed8ed1ee9d9ac6aa267b34a72afeb1121d83f4d3870229494@185.194.219.116:30303

Run a node

Option A — Docker (recommended, any OS)

git clone https://github.com/ethereum-1/mainnet.git
cd mainnet
cp .env.example .env
docker compose up -d
docker compose logs -f          # watch it init genesis and start syncing

The first boot builds CoreGeth from the exact pinned commit, writes the genesis state, and connects to the bootnode automatically. Data persists in the ethereum1-data Docker volume. JSON-RPC is off by default — set RPC_ENABLED=true in .env to expose eth,net,web3 on 127.0.0.1:8545.

Option B — native (Linux/amd64)

git clone https://github.com/ethereum-1/mainnet.git
cd mainnet
./scripts/install-geth.sh        # downloads the client + verifies sha256
./scripts/init-node.sh           # writes genesis state
./scripts/run-node.sh            # starts the node (add --http to enable RPC)

Prefer to build the client yourself? Build CoreGeth at commit 10f1ea745 (make geth) and point GETH=/path/to/geth at the scripts. For an always-on service, see systemd/ethereum1-node.service.

Connect a wallet (MetaMask, etc.)

Field	Value
Network name	Ethereum I
New RPC URL	https://rpc.ethereum1.org
Chain ID	588588
Currency symbol	ETH1
Block explorer	https://explorer.ethereum1.org

Step-by-step: docs/CONNECT-WALLET.md.

Verify what you're running

The genesis is the network's source of truth. Initializing it must print the genesis hash above:

geth --datadir /tmp/eth1-verify init genesis.json   # -> ...Successfully wrote genesis state ... hash=10c89f..23275a

What's in here

genesis.json        Network genesis (defines the chain; do not edit)
config.toml         Full-node config with the bootnode baked in
docker-compose.yml  One-command Docker boot
Dockerfile          Builds CoreGeth from the pinned commit
entrypoint.sh       Container init-then-run logic
scripts/            Native install / init / run helpers
systemd/            Service unit template for native installs
networks.json       Machine-readable chain metadata
docs/               Detailed run + wallet guides
