The polkadot protocol will soon introduce BLS signing by validators for consensus proofs. Work was previously done by the web3 foundation to make this verifiable on ethereum through apk-proofs.

Discuss the verifier complexity of BLS signature verification. Accounting for the rogue key attack.

However, a lack of support for the bw6-767 curve on ethereum for the outer curve means we need to check APK proofs in a non-native curve that’s available on ethereum.

The goal is to use the public keys as a sum.
