In his latest post, Buterin introduces this innovative protocol as a significant advancement in the realm of cryptographic proofs.
It is specifically designed to enhance performance while maintaining robust security. Let’s discover more about Buterin’s Circle STARKs.
Buterin’s New Protocol Enhances Cryptographic Efficiency
Circle STARKs represent a leap forward by employing smaller fields like Mersenne31 to optimize the proving speed of scalable transparent arguments of knowledge (STARKs). Traditionally, STARKs are built upon 256-bit fields. While these fields offer substantial security, they often result in inefficiencies that slow down the proving process.
Buterin’s new approach, utilizing smaller fields, addresses this issue by significantly reducing computational costs and accelerating proving speeds. For instance, the Circle STARKs protocol can verify up to 620,000 Poseidon2 hashes per second on an M3 laptop, showcasing a dramatic performance improvement.

One of the notable advancements in Circle STARKs is its ability to balance security with efficiency. Conventional small fields have been known to be prone to brute-force attacks due to their limited set of possible values. However, Buterin’s protocol tackles this vulnerability head-on. Circle STARKs incorporate multiple random checks and extension fields to expand the range of values that attackers would need to guess, thus creating a computational barrier that deters potential attacks.
Buterin’s post highlights that while previous STARK implementations made smaller fields compatible with verifying elliptic curve-based signatures, they often led to inefficiencies due to the large numbers involved. Circle STARKs overcome these challenges by optimizing the use of smaller fields, which enhances both the speed and efficiency of cryptographic operations without compromising on security.
