Some algorithmic stablecoins have proposed incorporating price feeds by asking their token holders. In this post, we point out that this mechanism is broken because of a fundamental incentive misalignment.

Achieving true decentralization requires decentralized cryptography. CHURP is a cryptographic protocol for secret sharing in decentralized settings. In such a setting where nodes may come and go, traditional secret sharing (e.g., Shamir's) is no longer secure. Featuring several fundamental innovations, CHURP accomplishes the mission while being 2300x more efficient than previous schemes!
