Question of bls signature - Miscellaneous - Ethereum Research Ethereum Research Question of bls signature Miscellaneous signature-aggregation yyyyyp July 23, 2019, 8:23am 1 Can you tell me the progress of BLS signature.Such as the specifics of the BLS’s integration with consensus, the efficiency of the validation of signature aggregation. As far as I know, using the BLS signature also requires additional public key transfers，will this influence the efficiency？ yyyyyp July 25, 2019, 2:24am 2 can anyone answer it？ yyyyyp August 6, 2019, 6:35am 3 bls is a big problem kladkogex August 13, 2019, 12:17pm 4 At SKALE we are developing a BLS library for general use. It also includes threshold encryption. It is in process of getting improved and documented. Your are welcome to use it. It is licensed under AGPL 3.0 GitHub skalenetwork/libBLS Top-performance BLS threshold signatures, threshold encryption, distributed key generation library in modern C++. Actively maintained and used by SKALE for consensus, distributed random number gen,... yyyyyp August 14, 2019, 3:31am 5 thanks for your reply,Can you provide some benchmark data，and do your library support the go language kladkogex August 14, 2019, 4:10pm 6 It does around a 1000 signings per sec on my PC. We will be adding a command line for it soon. Then you will be able to call this from go easily. yyyyyp August 15, 2019, 2:13am 7 1000signings means 1000 individual signatures or aggregate signatures ？ kladkogex August 15, 2019, 9:47pm 8 1000 individual signings for a BLS share. Actually a signing involves a single exponentiation in a field, so it is not so expensive … yyyyyp August 16, 2019, 2:45am 9 Validation time may be more important than signature time because it involves pairing. How long does it take you to verify the signature? One more thing, I find that you are using a bn128 curve, but as far as I know it can only achieve 110bit security. What do you think about this? Have you considered bls12-381 kladkogex August 16, 2019, 9:05pm 10 yyyyp - I am going to ETH Berlin but I will have Sveta Rogova who is our BLS tsar get measure this and get back to you p_m August 29, 2019, 1:28am 11 Check out our pure JS implementation: https://github.com/paulmillr/noble-bls12-381 Works in node and browsers.
