Ce court article décrit comment faire tourner un noeud BSC (Binance Smart Chain) sur une machine Linux


Mainnet

mkdir ~/bsc && cd $_
wget https://github.com/binance-chain/bsc/releases/download/v1.0.7/geth_linux
wget $(curl -s https://api.github.com/repos/binance-chain/bsc/releases/latest |grep browser_ |grep mainnet |cut -d\" -f4)
mv ./geth_linux ./geth_bsc

# Note: you can eventually move the binary to /usr/bin/ 

sudo chmod +x ./geth_bsc
./geth_bsc --datadir node init genesis.json

# Start the full Node
./geth_bsc --config ./config.toml --datadir ./node --pprofaddr 0.0.0.0 --metrics --pprof --verbosity 6 --nousb --cache=8192

# Dans un autre terminal
cd ~/bsc/node
tail -f ./bsc.log

August 2021 Update

BREAKING CHANGE: Non-EIP155 transactions (i.e. transactions which are not replay-protected) are now rejected by the RPC API. You can disable this restriction using the –rpc.allow-unprotected-txs command-line flag.

./geth_linux --config ./config.toml --datadir ./node --cache 18000 --rpc.allow-unprotected-txs --txlookuplimit 0

Ou dans mon cas:
./geth_linux --config ./config.toml --datadir ./node --cache 18000 --rpc.allow-unprotected-txs --http.api 8545 --http.addr 0.0.0.0 --http --ws --metrics --ws.addr 0.0.0.0 --verbosity 6 --txlookuplimit 0

I use geth-linux version 1.1.1

May 2022 Update

Mise à jour de la procédure d’installation:

wget https://github.com/binance-chain/bsc/releases/download/v1.1.10/geth_linux
mv ./geth_linux ./geth_bsc
sudo chmod +x ./geth_bsc
wget $(https://api.github.com/repositories/265775217/releases/latest |grep browser_ |grep mainnet |cut -d\" -f4)
unzip mainnet.zip
./geth_bsc --datadir node init genesis.json
./geth_bsc --config ./config.toml --datadir ./node --diffsync --cache 8000 --rpc.allow-unprotected-txs --txlookuplimit 0

Pour voir les logs dans un autre terminal:

cd ~/bsc/node
tail -f ./bsc.log

Troubleshooting

  • web3.exceptions.ExtraDataLengthError: The field extraData is 517 bytes, but should be 32.: Web3 essaye de se connecter à une “POA chain”.

    Workaround: 
    from web3.middleware import geth_poa_middleware
w3.middleware_onion.inject(geth_poa_middleware, layer=0)

  • web3.exceptions.BadFunctionCallOutput: Could not transact with/call contract function, is contract deployed correctly and chain synced?: utiliser transact() à la place de call()
