Today's learning reading on BLS signature aggregations. https://crypto.stanford.edu/~dabo/pubs/papers/BLSmultisig.html We all know BLS signature aggregation helps reduce the amount of pairings needed when validating signatures from N signers. But what if they are signing on different messages?

Well turns out that you can still aggregate, and it still helps, especially if not all messages are distinct. For example if you have N signers, but only on 3 distinct messages, you can still aggregate them in groups and reduce it to 3+1=4 pairings.
