1803	Rename opcodes for clarity	Alex Beregszaszi (@axic)	Standard Track	Core	Draft	2017-07-28

Abstract

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

Specification

Rename the opcodes as follows:

• BALANCE to EXTBALANCE to be in line with EXTCODESIZE and EXTCODECOPY
• SHA3 to KECCAK256
• NUMBER to BLOCKNUMBER
• GASLIMIT to BLOCKGASLIMIT to avoid confusion with the gas limit of the transaction
• GAS to GASLEFT to be clear what it refers to

Backwards Compatibility

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

Implementation

Not applicable.
