Nomad is an optimistic interoperability protocol that enables secure cross-chain communication.
Users can bridge tokens between chains
Asset issuers can deploy tokens across chains
DAOs can facilitate the execution of cross-chain governance proposals
Developers can build native cross-chain applications (xApps)
The goal of Nomad is to provide the connective tissue to enable users and developers to interact securely in a multi-chain world.
How does Nomad work?
Nomad enables applications to send data between blockchains (including rollups). Applications interact with Nomad core contracts to enqueue messages to be sent, after which off-chain agents verify and ferry these messages between chains.
In order to ensure that message-passing is secure, Nomad uses an optimistic verification mechanism, inspired by fraud-proof based designs like optimistic rollups. This makes Nomad more secure, cheaper, and easier to deploy compared to validator / proof-of-stake based interoperability protocols.
