IoTeX has been working on technological innovation and has recently made a breakthrough in building optimal bucketing, which has improved the performance of ZKP by 20-30%. The paper is currently undergoing peer review in the Journal of Cryptology and will be deployed on W3bstream together with cooperative provers such as RISC0. At the same time, IoTeX has cooperated with Filecoin, Textile, RISC0 and WeatherXM to launch a modular solution to the problem of centralization of DePIN economic distribution, which can facilitate developers to easily build programs, ensure the security, transparency and verifiability of off-chain data, and thus protect the incentive distribution of all participants.
