PANews reported on April 22 that according to the Hyper Foundation announcement, the Hyperliquid validation node set has been updated to 21 unlicensed nodes. Any user can register a node, and the top 21 stakers will form the active set. Nodes are required to pledge 10,000 HYPEs, which will be locked for one year and will not be refunded even if they are not selected for the active set. The official recommendation is to familiarize yourself with the testnet before the mainnet goes live, and to apply for the Delegation Program first. The program will be launched in the next few days to allocate token support to high-quality validation nodes.
