A Short History of Plonky2If you’re interested in the development of the ideas behind Plonky2, read on for a very high-level version.2018/2019Eli Ben-Sasson and the Starkware team introduced STARKs in 2018, the first fully transparent, quantum-safe proof system with a scalable verifier. In 2019, the DEEP-FRI paper, describing further optimizations to FRI, the PCS powering STARKs, was released. STARKs demonstrated that a variant of PCPs (Probabilistically Checkable Proofs) known as IOPs (Inter...
