He studied math and computer science at MIT, where he earned his SB, MEng and PhD.
[3] In 2013, Chiesa coauthored a paper and implementation of TinyRAM, a virtual machine whose execution could be proven using zero-knowledge proofs.
[4] In 2014, Chiesa coauthored the design of Zerocash,[5] which laid the foundation for the Zcash protocol.
The work was recognized by the Test of Time Award at the IEEE Symposium on Security and Privacy.
[6] In 2020, Chiesa coauthored the design of Zexe, a related protocol which drew on ideas from Zerocash and extended it to arbitrary computations.
