 Effective BLS-signature verification based on BLS12-381 elliptic curve will be useful for c*ross-chain interactions.* Some of the blockchains use the BLS signature in the protocols. If we want to implement the Clients for this blockchain on-chain in Near, we should be able to effectively verify the BLS signature. We can want to have a Client for a specific blockchain on Near for creating a bridge to verify the transaction from another blockchain and use it in Near. Examples of blockchains that use BLS signature based on BLS12-381: Eth2.0[[3](https://github.com/ethereum/consensus-specs/blob/master/specs/phase0/beacon-chain.md)], Filecoin[[6](https://spec.filecoin.io/)] and Tezos[[5](https://wiki.tezosagora.org/learn/futuredevelopments/layer2#zkchannels)]. Especially, it is necessary for Rainbow Bridge[[17](https://near.org/blog/eth-near-rainbow-bridge)] to make trustless transfers from Ethereum 2.0 to Near.

Zeropool[[20](https://zeropool.network/)] is a project who implements zkSNARKs verifier on Near and is currently based on alt-bn128. Implementation of the precompiles for BLS12-381 can make the projects like that more secure. zkSNARKs is also used in Roll Ups[[21](https://www.youtube.com/watch?v=al4YpfDVmS4&ab_channel=EthereumCatHerders),[22](https://near.org/blog/layer-2),[23](https://www.ledger.com/academy/what-are-blockchain-rollups)] scaling solutions.

 This proposal is based on a similar proposal for Ethereum: EIP-2537[[15](https://eips.ethereum.org/EIPS/eip-2537)].
