# Running Geth

# Requirements

  • Geth (install guide)
  • jq (brew install jq, apt-get install -y jq, dnf install -y jq)

# Geth version

The ASK blockchain currently runs go-ethereum v1.8.19

# Running

To run geth locally, simply copy this script and run it. It will pull in the publicly hosted testnet genesis block and list of bootnodes.

curl -LO https://s3.amazonaws.com/ask-blockchain/testnet/genesis.json
curl -LO https://s3.amazonaws.com/ask-blockchain/testnet/bootnodes.json
 
mkdir data
geth init --datadir=./data genesis.json
 
cat << 'EOF' > runTestnet.sh
geth \
    --datadir ./data \
    --syncmode fast \
    --networkid 2221 \
    --rpc \
    --rpcaddr '0.0.0.0' \
    --rpcport 8545 \
    --rpcapi 'personal,db,eth,net,web3,txpool,miner,admin,debug,clique' \
    --rpccorsdomain '*' \

    --wsapi 'personal,db,eth,net,web3,txpool,miner,admin,debug,clique' \
    --wsorigins '*' \
    --port 1111 \
    --bootnodes $(cat bootnodes.json | jq -r '. | join(",")')
