Abstract¶

Rename the BALANCE, SHA3, NUMBER, GASLIMIT, GAS and INVALID opcodes to reflect their true meaning.

Specification¶

Rename the opcodes as follows: - BALANCE (0x31) to EXTBALANCE to be in line with EXTCODESIZE, EXTCODECOPY and EXTCODEHASH - SHA3 (0x20) to KECCAK256 - NUMBER (0x43) to BLOCKNUMBER - GASLIMIT (0x45) to BLOCKGASLIMIT to avoid confusion with the gas limit of the transaction - GAS (0x5a) to GASLEFT to be clear what it refers to - INVALID (0xfe) to ABORT to clearly articulate when someone refers this opcode as opposed to "any invalid opcode"

Backwards Compatibility¶

This has no effect on any code. It can influence what mnemonics assemblers will use.

Implementation¶

Not applicable.

References¶

DIP-6 previously renamed SUICIDE (0xff) to SELFDESTRUCT. Renaming SHA3 was previously proposed by DIP-59.
