Silvio Micali (born October 13, 1954) is an Italian computer scientist, professor at the Massachusetts Institute of Technology and the founder of Algorand, a proof-of-stake blockchain cryptocurrency protocol.

Micali's research at the MIT Computer Science and Artificial Intelligence Laboratory centers on cryptography and information security.

Micali is best known for some of his fundamental early work on public-key cryptosystems, pseudorandom functions, digital signatures, oblivious transfer, secure multiparty computation, and is one of the co-inventors of zero-knowledge proofs.

[9] His former doctoral students include Mihir Bellare, Bonnie Berger, Shai Halevi, Rafail Ostrovsky, and Phillip Rogaway.
