COLORTRACE: FUNGIBLE TOKEN COLORING AND ATTRIBUTION

Summary from the TLDR Crypto newsletter

LayerZero has introduced ColorTrace, an algorithm that aims to solve the "fungible token coloring problem" - keeping track of specific fungible tokens and their origins. The algorithm aims to keep track of tokens upon transfer and redemption and reward minters proportionally. It offers a single-chain and cross-chain token color solution with "globally consistent" and "economically feasible" token coloring. This paper discusses potential applications of ColorTrace, such as stablecoin collateral tracking.
