Nomad realized that while header relays or light client were theoretically considered the most secure way to build cross-chain bridges, they were not scalable and difficult to deploy across heterogeneous ecosystems. Light client require expertise in proof-of-work and proof-of-stake implementation and are not friendly to new developers.

The most important aspect of this proposed token model is that it is sustainable. The staking incentives are more sustainable because they benefit those who are “first in, last out” as opposed to the typical accounting principle of First In, First Out (FIFO).
