据，执行引擎同时支持EVM合约与预编译合约，其中EVM合约可以通过交易 创建合约、合约创建合约两种方式来创建，其执行流程如下： ../../../_images/EVM_contract_execution.png EVM合约创建后，保存到执行上下文的_sys_contracts_表中，EVM合约的地 址在区块链全局状态内自增，从0x1000001开始（可定制），EVM合约执行 过程中，Sto 00截止，临时 预编译合约仅在执行上下文内有效预编译合约没有Storage变量，只能操作 表，其执行流程如下： ../../../_images/precompiled_contract_execution.png 同步 同步，是区块链节点非常重要的功能。它是共识的辅助，给共识提供必需的 运行条件。同步分为交易的同步和状态的同步。交易的同步，确保了每笔交 易能正确的到达每个节点上。状态的同步，能确保区块落后的节点能正确的 赖边；若该交易不可并行，则认为其必须在前序的所有交易都执行完后 才能执行，因此在该交易与其所有前序交易间建立一条依赖边。 3.2 DAG执行流程 流程如下： ../../../_images/execution.png 1. 主线程会首先根据硬件核数初始化一个相应大小的线程组，若获取硬件 核数失败，则不创建其他线程； 2. 当DAG尚未执行完毕时，线程循环等待从DAG中pop出入度为0的交易。

 • Transparent graph logic to engineer.
