bls for eth with compiled static library

This repository contains compiled static library of https://github.com/herumi/bls with BLS_ETH=1.

• SecretKey; Fr
• PublicKey; G1
• Sign; G2

News

The new eth2.0 functions are supported.

Init as the followings:

Init(BLS12_381)
SetETHmode(1)

then, you can use the following functions.

bls-eth-go-binary	eth2.0 spec name
SecretKey::SignByte	Sign
PublicKey::VerifyByte	Verify
Sign::Aggregate	Aggregate
Sign::FastAggregateVerify	FastAggregateVerify
Sign::AggregateVerifyNoCheck	AggregateVerify

The size of message must be 32 byte.

Check functions:

• VerifySignatureOrder ; make deserialize check the correctness of the order
• Sign::IsValidOrder ; check the correctness of the order
• VerifyPublicKeyOrder ; make deserialize check the correctness of the order
• PublicKey::IsValidOrder ; check the correctness of the order
• AreAllMsgDifferent ; check that all messages are different each other

How to run sample.go

go get github.com/herumi/bls-eth-go-binary/
go run sample.go

How to build the static library

The following steps are not necessary if you use compiled binary in this repository.

Linux, Mac, Windows(mingw64)

mkdir work
cd work
git clone https://github.com/herumi/mcl
git clone https://github.com/herumi/bls
git clone https://github.com/herumi/bls-eth-go-binary
cd bls-eth-go-binary
make CXX=clang++

clang generates better binary than gcc.

Android

make android

iOS

make ios

How to use the static library from C
