Vitalik Buterin Unveils Circle STARKs for Enhanced Blockchain Efficiency
Ethereum co-founder Vitalik Buterin has introduced a new cryptographic protocol named Circle STARKs, designed to significantly improve blockchain security and efficiency. In a recent post, Buterin explained how this technological advancement leverages smaller fields to enhance proving speed without compromising security.
Smaller Fields, Bigger Gains
Traditional STARKs （Scalable Transparent Arguments of Knowledge） operate over 256-bit fields, which are secure but often inefficient. Circle STARKs utilize smaller fields like Mersenne31, reducing computational costs and improving proving speed. This efficiency gain enables the verification of 620,000 Poseidon2 hashes per second on an M3 laptop.
Enhanced Security Measures
One of the key advantages of Circle STARKs is their enhanced security. Smaller fields have limited possible values, which can be vulnerable to brute-force attacks. Circle STARKs mitigate this risk through multiple random checks and the use of extension fields, expanding the set of values attackers need to guess. This approach creates a computationally prohibitive barrier for attackers, maintaining the protocol’s integrity.
Practical Applications
Circle STARKs offer flexibility and versatility for efficient computational performance. The Fast Reed-Solomon Interactive Oracle Proofs of Proximity （FRI） prove that a function is a polynomial of a certain degree, a critical aspect of Circle STARKs. By introducing Circle FRI, the protocol ensures that non-polynomial inputs fail the proof, maintaining the cryptographic process’s integrity.
