创世块

主网和测试网的创世块信息硬编码在底层代码中，创世块文件如下。

为保持系统合约的一致性，系统合约地址的code 硬编码在代码中，不在创世块文件中呈现。

定义

• chainId 区块链标识。

• homesteadBlock 、eip150Block 、eip150Hash 、eip155Block、 eip158Block 、byzantiumBlock 、constantinopleBlock 、petersburgBlock 、istanbulBlock 、muirGlacierBlock 区块链硬分叉区块配置。

• dpos 共识参数配置。

  • period 出块时间间隔。

  • epoch 一周期的持续块数。

• number 、gasUsed 、parentHash 、nonce 、timestamp 、 gasLimit 、difficulty 创世块基本信息。

• extraData 用以配置初始出块节点。

• alloc 配置初始账户信息。
