# 摘要
An instruction is designated to remain as an invalid instruction.
# 动机
The invalid instruction can be used as a distinct reason to abort execution.
# 规范
The opcode 0xfe is the INVALID instruction. It can be used to abort the execution (i.e. duplicates as an ABORT instruction).
# 向后兼容
This instruction was never used and therefore has no effect on past contracts.
