BLS signature

Ethereum uses BLS signatures to efficiently aggregate thousands of validator signatures per slot.以太坊使用 BLS 签名来高效聚合每个时隙中的数千个验证者签名。

BLS signature aggregation reduces the on-chain verification cost of consensus from O(n) to near O(1) in validator count.BLS 签名聚合将共识的链上验证成本从验证者数量的 O(n) 降低到接近 O(1)。
