Network rewarding machine-learning models for useful output.
Generic message-passing layer connecting heterogeneous chains.
Wormhole moves arbitrary messages between chains, with token bridging as one application built on top. A guardian network observes and attests to events on a source chain, and those attestations are verified on the destination. Cross-chain messaging is among the highest-risk surfaces in the industry, and Wormhole itself suffered a major exploit in 2022 before being rebuilt and audited further.
