Vitalik Buterin offers Circle STARKs to enhance blockchain success

Vitalik Buterin discloses Circle STARKs, an innovative protocol that optimizes blockchain security and efficiency by employing small-field cryptography.

Buterin says in his most recent essay that this technical advance takes use of smaller fields such as Mersenne31 to dramatically boost proving speed while maintaining security precautions.

According to the text, standard Scalable Transparent ARguments of Knowledge (STARKs) use 256-bit fields, which are secure yet wasteful.

Circle STARKs utilize smaller fields, which leads to more efficient benefits, faster-proving velocities, and reduced computational costs. For instance, an M3 laptop can verify 620,000 Poseidon2 hashes per second.

Buterin observes that the previous STARK implementation was “naturally compatible” with verifying elliptic curve-based signatures because of the smaller fields. However, the large numbers involved resulted in inefficiency.

Traditional small fields are susceptible to brute-force attacks and have restricted potential values. Circle STARKs mitigate this vulnerability by employing extension fields and conducting numerous random tests, thereby broadening the range of values that attackers must predict.

This security measure establishes a computational barrier that is prohibitive to adversaries, thereby preserving the integrity of the protocol.

The issue with STARKs over smaller fields is that there are only approximately two billion possible values of x to select from. Consequently, an attacker who wishes to create a fabricated proof must only attempt to do so two billion times—a substantial amount of work, but one that is quite feasible for a determined attacker.

The Fast Reed-Solomon Interactive Oracle Proofs of Proximity (FRI) are a critical component of Circle STARKs, as they establish that a function is a polynomial of a specific degree.

Introducing Circle FRI, an approach that guarantees the integrity of the cryptographic process, Circle STARKs guarantee that non-polynomial inputs fail the proof.

By utilizing compact fields and this new mathematical structure, Circle STARKs provide increased flexibility and versatility for efficient computational performance.
