• Vitalik Buterin revealed a new blockchain protocol for enhancing efficiency, Circle STARKs.
• Circle STARKs will utilize smaller fields to improve speed and maintain security.
• Polygon Labs and StarkWare are major collaborators in building Circle STARKs for ZK rollups.

Vitalik Buterin unveiled Ethereum's latest protocol, Circle STARKs, on Tuesday. The protocol aims to boost blockchain efficiency for Layer 2 networks through small-field cryptography.

Polygon and StarkWare partner with Ethereum to launch Circle STARKs

Ethereum co-founder Vitalik Buterin revealed the recent launch of Circle STARKs, a new cryptographic protocol developed by the joint effort of Polygon Labs and StarkWare. The protocol aims to improve the scalability and security of blockchain networks.

Scalable Transparent Arguments of Knowledge (STARKs) are a type of cryptographic proof that enhances the efficiency and security of a blockchain while maintaining its transparency.

Over the last two years, the STARK protocol design has switched from larger fields to working over small fields to enable faster transactions. This made the protocols "naturally compatible with verifying elliptic curve-based signatures and made them easy to reason about," said Buterin.
