Descrizione

Simple Summary

Add support for blake2 cryptographic hash function

Motivation

Blake2 is a newer but popular hash function that is being used in a variety of circumstances including ZKP due to it's efficiency under pairing operations. Support in Vyper would make it easier to develop applications that use it.

Specification

Support for Blake2 is being added in the upcoming Istanbul hardfork. The specification is in EIP-152, and a reference implementation in a client is here: https://github.com/ethereum/py-evm/blob/master/eth/precompiles/blake2.py

Function signature:

blake2b_f() -> bytes32[2]
