1) Ethan的答复参考了黄皮书中的正式操作码列表。它可能有点干燥,很难导航到新来的人。我最喜欢的列表是:https://github.com/djrtwo/evm-opcode-gas-costs。它很容易导航,它也包含操作代码的气体信息。

( 2)一些操作码可能在正式的YP列表中丢失。想到的一个例子是REVERT (0xFD)。我相信这个操作码是在大都会第一阶段(Byzantium)引入的,在YP中还没有提到。因此,您最好的参考将是实际的客户端实现,或稳健的实现。示例:https://github.com/ethereum/solidity/blob/develop/libevmasm/Instruction.h (以及.c )。但是,要小心客户端的实现,它们可能包含仍然是实验性的操作码。
