1.先下载bsc创始块合约库编译生成用于私链的配置文件genesis.json
https://github.com/binance-chain/bsc-genesis-contract/archive/refs/tags/v1.0.3.zip
主要配置init_holder.js和validators.js分别添加默认账户和出块验证者列表。
init_holder.js
const init_holders = [
{
// private key is 0x9b28f36fbd67381120752d6172ecdcf10e06ab2d9a1367aac00cdcd6ac7855d3, only use in dev
address: "0x9fB29AAc15b9A4B7F17c3385939b007540f4d791",
balance: web3.utils.toBN("10000000000000000000000").toString("hex")
}
];validators.js
// Configure
const validators = [
{
consensusAddr: "0x0b25F687Df22EB7dc55e6d547749b229811C3dAe",
feeAddr: "0x0b25F687Df22EB7dc55e6d547749b229811C3dAe",
bscFeeAddr: "0x0b25F687Df22EB7dc55e6d547749b229811C3dAe",
votingPower: 0x0000000000000064
},
{
consensusAddr: "0x7e83150c703F75547D0Bf5c08E8209Da0Ae4a40C",
feeAddr: "0x7e83150c703F75547D0Bf5c08E8209Da0Ae4a40C",
bscFeeAddr: "0x7e83150c703F75547D0Bf5c08E8209Da0Ae4a40C",
votingPower: 0x0000000000000064
},
{
consensusAddr: "0x4193803810050169F19f2eb45793399AE443275c",
feeAddr: "0x4193803810050169F19f2eb45793399AE443275c",
bscFeeAddr: "0x4193803810050169F19f2eb45793399AE443275c",
votingPower: 0x0000000000000064
}
];2.下载bsc1.1.1源码编译 https://github.com/binance-chain/bsc/archive/refs/tags/v1.1.1.zip
编译geth模块源码生成2个以上的私链节点，分别用以上生成的genesis.json构建创世快，配置大概如下
# 启动节点0, 关闭自动发现（防止不希望的节点进入）
geth --datadir node0 init genesis.json
geth --datadir node0 --port 30000 --nodiscover --unlock '0' --password ./node0/password console
# 不加console的话，可以通过geth attach ipc:node0/geth.ipc来访问
# 启动节点1，另起一个终端，通过不同端口模拟
geth --datadir node1 init genesis.json
geth --datadir node1 --port 30001 --nodiscover --unlock '0' --password ./node1/password console
# 启动节点2，genesis.json里已经指定networkID,启动时无需指定了
geth --datadir node2 init genesis.json
geth --datadir node2 --port 30002 --nodiscover --unlock '0' --password ./node2/password console
1.下载erigon-bsc
git clone https://github.com/somewheel/erigon-bsc.git
2.编译erigon
go build ./cmd/erigon
3.启动
目前创始块的networkId及其他配置信息硬编码在代码里，暂时通过以下启动参数运行可同步bsc数据区块。
硬编码代码分别对应在
/params/config.go 328行
ParliaChainConfig = &ChainConfig{
ChainID: big.NewInt(97),
HomesteadBlock: big.NewInt(0),
DAOForkBlock: nil,
DAOForkSupport: false,
EIP150Block: big.NewInt(0),
EIP150Hash: common.Hash{},
EIP155Block: big.NewInt(0),
EIP158Block: big.NewInt(0),
ByzantiumBlock: big.NewInt(0),
ConstantinopleBlock: big.NewInt(0),
PetersburgBlock: big.NewInt(0),
IstanbulBlock: big.NewInt(0),
MuirGlacierBlock: big.NewInt(0),
BerlinBlock: big.NewInt(0),
LondonBlock: nil,
Ethash: nil,
Clique: nil,
Parlia: &ParliaConfig{Period: 3, Epoch: 200},
}/core/genesis.go 645行。 注意需要把ExtraData(同genesis.json的extraData字段)替换为私链的验证者们，此字段由第一步构建而成
func DefaultParliaGenesisBlock() *Genesis {
return &Genesis{
Config: params.ParliaChainConfig,
Timestamp: 0x5e9da7ce,
ExtraData: hexutil.MustDecode("0x00000000000000000000000000000000000000000000000000000000000000000b25f687df22eb7dc55e6d547749b229811c3dae4193803810050169f19f2eb45793399ae443275c7e83150c703f75547d0bf5c08e8209da0ae4a40c0000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000"),
GasLimit: 0x2625a00,
Difficulty: big.NewInt(1),
Coinbase: common.HexToAddress("0xffffFFFfFFffffffffffffffFfFFFfffFFFfFFfE"),
Alloc: readPrealloc("allocs/parlia.json"),
}
}/core/allocs/parlia.json文件存储的为创世块的系统合约代码和默认账户，可根据需求调整。
./erigon --datadir ./dev --chain parlia --nodiscover --staticpeers enode://d43a9bb1481d00cdbe3f103777c2968675419eee9d5cb4e9df434c0d620b28ea09459a2b4b18b660d4ad01f825c20d71e2f0b4f56107e4b356d5bdbb7c175213@127.0.0.1:30001?discport=0
--staticpeers 为上面构建的bsc任意私链节点地址，可通过admin.nodeinfo进行查询。
根目录下的genesis.json文件可作对比参考。
