atoulme opened a new issue #61: Blake2b F compression URL: https://github.com/apache/incubator-tuweni/issues/61 [EIP-152](https://github.com/ethereum/EIPs/blob/master/EIPS/eip-152.md) introduced a new Blake2b precompile contract for Ethereum. This blake2b compression is implemented by Sodium, but Ethereum chose to use a different sigma. **Motivation** Current implementations of blake2b are client-specific - there exists one for each client, so far. They also are implemented in Java where ideally they should be implemented in low-level C, and introduced via bindings. Finally, this could be easily done by adopting and extending the libsodium primitives. **Scope of work** * Identify how to best implement a fast blake2b function, probably by reusing libsodium approaches. * Bundle a C low-level primitive for this precompile with a simple Java wrapper - JNR, most likely.
