Aggregate signatures aren’t new. They’ve been around since the early 2000s. But building one that actually works in Bitcoin’s security model, with Bitcoin’s elliptic curve, has never been proven.

Three weeks ago, panic swept across some corners of the security world after researchers discovered a breakthrough that, at long last, put the cracking of the widely used RSA encryption scheme within ...

Meet DahLIAS, a full aggregation signature scheme that works with secp256k1, Bitcoin's cryptographic curve. Aggregate signatures aren’t new. They’ve been around since the early 2000s. But building one ...
