chia-bls-go

  • go版本chia签名, 参考python-impl实现部分功能，并非bls的完全实现

Bug fix

  • 2024/01/18 Thanks for the code from coolaj86, a bug for checking length of pks on coreAggregateVerify was fixed!

  • 2023/07/08 Thanks for the report from goomario, a bug was fixed!

    • This bug was caused by the wrong use of big.Int.Bytes(), it should be replaced with big.Int.FillBytes()
