What is Zetachain? Just about complex.
ZetaChain is a public blockchain that enables communication and transactions between different blockchains. It is based on the consensus of Cosmos SDK and Tendermint, which are both well-established blockchain technologies.
The big advantage of ZetaChain is that it provides what is known as an "omni-channel" environment. This means that users and developers can move between them and appreciate the benefits of any blockchain. For example, if you want to use a blockchain with good privacy features for one transaction and another blockchain with high transaction speed for another transaction, you can easily switch between them using ZetaChain. This is different from the current state of the blockchain world, where each blockchain is essentially its own isolated ecosystem.
In simple words:
You live in the USA and you need to bring a TV set from England. Instead of long logistical considerations, wasting time and money on transportation, you can write to your green friend Zetaychain, who will bring you a TV set from England for 0.20$ in 5-10 minutes. Yes, he has a super cool plane that is better than Batman. And so that the zetachain does not deceive you, there will be a guard of your TV next to it, who will not take his eyes off the zetachain.
This way you save time, money and you know that everything happens in a safe mode without the risk of being deceived.
