Ethereum co-founder launches new protocol to enhance blockchain speed, security
Ethereum co-founder, Vitalik Buterin, has launched Circle STARKs, a new cryptographic protocol designed to enhance both security and efficiency in blockchain systems.
Vitalik Buterin’s latest innovation, Circle STARKs, aims to boost blockchain performance by leveraging small-field cryptography.
Traditional STARKs operate on 256-bit fields, ensuring security but often resulting in inefficiencies. Circle STARKs, however, use smaller fields, significantly reducing computational costs and speeding up the proof process without sacrificing security.
One of the key advantages of Circle STARKs is their ability to perform faster computations. By utilizing smaller fields, such as Mersenne31, Circle STARKs can verify 620,000 Poseidon2 hashes per second on an M3 laptop.
The introduction marks a substantial improvement over previous implementations, which struggled with efficiency due to the large numbers involved in traditional fields.
A common concern with small fields is their vulnerability to brute-force attacks due to a limited number of possible values.
Circle STARKs address this by incorporating multiple random checks and using extension fields, thus broadening the range of values an attacker would need to guess. This added layer of security makes it computationally prohibitive for attackers to breach the system, maintaining the integrity of the protocol.
Circle STARKs also introduce Circle FRI (Fast Reed-Solomon Interactive Oracle Proofs of Proximity), a method that ensures the cryptographic process remains robust by verifying that functions are polynomials of a certain degree. This innovation provides more flexibility and versatility, enhancing the overall computational performance of blockchain systems.
