Walraswap: equilibrium-based decentralized exchange integrating external AMM liquidity

In briefWalraswap: an equilibrium-based decentralized exchange that integrates external AMM liquidity

SummaryThis paper presents Walraswap, a decentralized exchange design based on equilibrium theory for exchange economies, which settles batches of trade orders together and can incorporate external AMM liquidity. The authors argue that equilibrium requires uniform clearing prices and inclusion of all available orders, and they propose governance by a DAO that elects solvers, with public order flow to discourage censorship. The paper also presents theoretical results on the existence, uniqueness of net trades, and computation via convex optimization.

TULIP: Permissionless Decentralized Identity

In briefTULIP: A permissionless decentralized identity concept

SummaryThe author proposes a pseudonymous identity system that avoids central coordinators and uses the Bitcoin blockchain as the timestamping and ordering authority for identity key changes. Keys rotate through a precommitted Taproot chain, keeping the onchain footprint small. A linked whitepaper, Tuliproot, also suggests a 4-byte witness header to help index important state-change transactions.
