Request Support for BLS12 based signature verification #940

Open sudesh-supraoracles opened 2 years ago

sudesh-supraoracles commented 2 years ago

Hi Team!

Since many protocols are putting BLS12 to use for digital signatures. I want to verify BLS 12 based signature from Polkadot smart contract.

Hoping for some positive inputs/response on this.

We'll add support for pairing based curve usage by parachain runtimes eventually via https://github.com/arkworks-rs/algebra/issues/730 plus https://github.com/paritytech/ark-substrate likely some testnet experimentation later this year. We've no reason for BLS signatures directly on polkadot/kusama. This issue can be closed.
