Ethereum co-founder Vitalik Buterin posted on X, sharing his hands-on experience with the mobile offline local knowledge base application built by the community team on the decentralized bounty protocol POIDH. He noted that compared to the solution he tried to set up himself two months ago, there has been significant progress in the developers' achievements. However, the mobile local model still responds more slowly and performs less effectively when dealing with complex problems, especially in vertical and specific travel-related queries. Vitalik expressed anticipation for the continuous iteration of offline AI technology on the server side and hopes that in the future, users will be able to retrieve any real-world facts and knowledge they are interested in smoothly and conveniently in a purely offline environment.
