#### What is Nomad's security model? How does it compare to other well-known models, such as header verification? <a href="#what-is-nomad-s-security-model-how-does-it-compare-to-other-well-known-models-such-as-header-verific" id="what-is-nomad-s-security-model-how-does-it-compare-to-other-well-known-models-such-as-header-verific"></a>

Every cross-chain message passing system is going to have [trade-offs](/the-nomad-protocol/verification-mechanisms/comparing-mechanisms.md), and we've carefully considered how security is affected with design choices. Nomad adopts an [optimistic mechanism](/the-nomad-protocol/verification-mechanisms/optimistic-verification.md) inspired by optimistic roll-ups like Optimism and Arbitrum, which is a different approach than block header verification, or [native verification](/the-nomad-protocol/verification-mechanisms/native-verification.md). Check out the section on [verification mechanisms](/the-nomad-protocol/verification-mechanisms.md) to read more about the various designs and their trade-offs.

#### Wen token? <a href="#wen-token" id="wen-token"></a>

Nomad does not have a token at this time. If you hear any references to a Nomad token, they are definitely scams.
