Mint Node

It currently supports Optimism’s open-source OP Stack.

This repository contains the relevant Docker builds to run your own RPC node for Mint Blockchain.

Hardware Requirements

Recommend minimal configuration to run a node:

• 2 Core * 8 GB RAM
• 800GB SSD Drive (Archive Node)

Running Node

Step1: Setting ETH L1 full-node RPC

• setting OP_NODE_L1_ETH_RPC. need fully synced.
• setting OP_NODE_L1_BEACON. need a Beacon RPC.

# .env
OP_NODE_L1_ETH_RPC=<your ETH rpc endpoint>
OP_NODE_L1_BEACON=<beacon api rpc>

Step2: Start the node

• Mainnet

docker compose -f docker-compose-mainnet.yml up --build -d

• Sepolia Testnet

docker compose -f docker-compose-testnet-sepolia.yml up --build -d

Step3: Check your node

curl -d '{"id":0,"jsonrpc":"2.0","method":"eth_blockNumber","params":[]}' -H "Content-Type: application/json" http://localhost:8545

Tips

1. You can map a local data directory for op-geth by adding volume mapping to docker-compose-xxx.yml:

services:
  geth: # this is Optimism's geth client
    volumes:
      - /data/node_data:/data

2. Default node type is archive. you can change it via op-geth-entrypoint.

--gcmode=full

Snapshots

Mainnet

• Archive https://storage.googleapis.com/mint-snapshot/mint-mainnet-archive-snapshot-20250214.tar.zst
• Full https://storage.googleapis.com/mint-snapshot/mint-mainnet-full-snapshot-20250214.tar.zst

Testnet

• Archive https://storage.googleapis.com/mint-snapshot/mint-sepolia-archive-snapshot-20250214.tar.zst

Usage

mkdir -p /data/node_data/geth

# Download, You can choose one of two ways to download，Using aria2c to download can improve download speed, but you need to install aria2
step1: download

wget -c  https://storage.googleapis.com/mint-snapshot/mint-mainnet-archive-snapshot-20250214.tar.zst 

step2: unarchive

aria2c -x 16 -s 16 -k 100M  https://storage.googleapis.com/mint-mainnet-archive-snapshot-20250214.tar.zst 

# unzip snapshot to the ledger path:
tar --use-compress-program=unzstd -xvf mint-mainnet-archive-snapshot-20250214.tar.zst -C /data/node_data/geth

step3: check
$ ls /data/node_data/geth
chaindata
