Introduction
A high-level introduction to Nomad
Using Nomad:
- 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.
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.
Our friends at Connext have written a fantastic article on optimistic bridging, and why Nomad's optimistic bridging ushers in a new paradigm for cross-chain communication.
