The Open Web information distribution protocol RSS3 announces the next stage, Stage3, and launch of the Open Web-oriented search engine, hoot.it. The hoot.it index includes blockchain networks and other networks in the Open Web, and users can conduct one-stop searches, including but not limited to on-chain transaction information, NFT, DApp, Web3 social protocols and other related data and content. In addition, hoot.it launched HootGPT, an application that trains AI language models based on GPT technology and Open Web data to assist queries. At this stage, RSS3 also optimized and upgraded the API to improve the response speed. The RSS3 API already supports all mainstream EVM-compatible networks and ecosystems such as IPFS and Arweave, Nostr, and Farcaster. RSS3 will continue to expand the coverage of information on the Open Web, improve the level of analysis, and gradually launch public nodes.
