ZetaChain is an L1 blockchain built using the Cosmos SDK. It introduces PoS.
It is an omnichain that connects with blockchains that do not implement smart contracts such as Bitcoin and DogeCoin, and Layer2 (Optimism, Arbitrum, etc.).
ZetaChain plans to use $ZETA as a key token. A major feature of ZetaChain is its secure bridge function.
Why is it safe?
This is because tokens can be moved to other blockchains/layers other than ZetaChain without wrapping.
A traditional bridge function holds a certain amount of tokens that can be bridged on the chain of origin and destination.
This can lead to large sums of money being accumulated in one place, motivating crackers to attack.
However, in the case of ZetaChain, $ZETA is disposable and reissued many times, so this risk is greatly reduced.
In this way, ZetaChain's strength is that it can overcome the problems of conventional cross-chains.
