This module is built with BLS_ETH=1 for Ethereum 2.0 spec.

• 2024/Sep/30 : About 4% performance improvement
• 2024/Sep/18 : About 10% performance improvement
• 2022/Jul/20 : 1.1 times improved
• 2021/Aug/28 : improve performance of {G1,G2}::isValidOrder()
• 2020/Nov/04 : break backward compatibility (bls.js is renamed to index.js)
  • use blsSetupFactory to make bls instance on browser (see the top of bls-demo.js)
• 2020/Oct/01 : add bls.multiVerify to verify all {sigs, pubs, msgs}.
• 2020/Jul/06 ; setETHmode(bls.ETH_MODE_DRAFT_07) is default mode

The version v0.4.2 breaks backward compatibility of the entry point.

• Node.js : const bls = require('bls-eth-wasm')
• React : const bls = require('bls-eth-wasm/browser')
• HTML : <script src="https://herumi.github.io/bls-eth-wasm/browser/bls.js"></script>

Init as the followings:

bls.init(bls.BLS12_381)

(old) The new eth2.0 functions are supported. This mode will be removed in the future.

Init as the followings:

bls.init(bls.BLS12_381)

then, you can use the following functions.

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
