ExChain mainnet

This repo collects the genesis and configuration files for the various ExChain mainnet. It exists so the ExChain repo does not get bogged down with large genesis files and status updates.

Startup an exchain full node by the exchaind binary

1. Build exchaind by the latest released version

# latest_version refers to https://github.com/okx/exchain/releases/latest
git clone -b latest_version https://github.com/okx/exchain.git  
cd exchain
make mainnet

2. Startup a full node by a snapshot. (recommended)

There are 3 types of snapshots and s0 is the one with minimum data size:

s0: the most recent block and world state
s1: all historical blocks and the most recent world state
s3: all historical blocks and world states

# 1. Initialize exchain node configurations
export EXCHAIND_PATH=~/.exchaind (or a cutomized one)
exchaind init your_custom_moniker --chain-id exchain-66 --home ${EXCHAIND_PATH}

# 2. download snapshot
rm -rf ${EXCHAIND_PATH}/data
cd ${EXCHAIND_PATH}
wget https://okg-pub-hk.oss-cn-hongkong.aliyuncs.com/cdn/okc/snapshot/mainnet-$version-$date-$height-rocksdb.tar.gz
tar -zxvf mainnet-$version-$date-$height-rocksdb.tar.gz

# 3. start exchaind
exchaind start --home ${EXCHAIND_PATH}

3. Startup a full node by the Genesis block. (taking long, not recommended)

export EXCHAIND_PATH=~/.exchaind (You can also specify other directory)

exchaind init your_custom_moniker --chain-id exchain-66 --home ${EXCHAIND_PATH}

wget https://raw.githubusercontent.com/okex/mainnet/main/genesis.json -O ${EXCHAIND_PATH}/config/genesis.json

exchaind start --chain-id exchain-66 --home ${EXCHAIND_PATH}

Note: it needs to check the genesis file

$ shasum -a 256 ${EXCHAIND_PATH}/config/genesis.json
0958b6c9f5f125d1d6b8f56e042fa8a71b1880310227b8b2f27ba93ff7cd673b  ${EXCHAIND_PATH}/config/genesis.json

Startup an exchain full node with docker

1. make the data dir

mkdir -p ~/.exchaind/data
echo '{\n"height": "0",\n"round": "0",\n"step": 0\n}' > ~/.exchaind/data/priv_validator_state.json

2. run docker image

docker run -d --name exchain-mainnet-fullnode -v ~/.exchaind/data:/root/.exchaind/data/ -p 8545:8545 -p 26656:26656 okexchain/fullnode-mainnet:latest

3. check log

docker logs --tail 100 -f exchain-mainnet-fullnode

4. stop and remove the docker container

docker rm -f exchain-mainnet-fullnode

5. restart

You can restart in the previous data dir

docker run -d --name exchain-mainnet-fullnode -v ~/.exchaind/data:/root/.exchaind/data/ -p 8545:8545 -p 26656:26656 okexchain/fullnode-mainnet:latest

Upgrade an exchain full node to latest

1. Stop exchain full node

2. Build exchaind binary

Build exchaind by the latest released version

git clone -b latest_version https://github.com/okex/exchain.git  # latest_version refers to https://github.com/okex/exchain/releases/latest
cd exchain
make mainnet

3. Start

export EXCHAIND_PATH=~/.exchaind (You can also specify other directory)
exchaind start --chain-id exchain-66 --home ${EXCHAIND_PATH}
