ZetaChain is the first “omnichain” layer1 blockchain. Applications deployed on ZetaChain can access most of crypto chains. Instead of deploying an application on every chain, developers can now deploy on ZetaChain and target any blockchain. This simplifies the interoperability and messaging between chains. This also helps the development of smart contracts on a blockchain that does not support them natively, like dogecoin.

In short, ZetaChain is a full blockchain that can tap into any blockchain, bridge and transfer assets between blockchains.

Zeta coin

Unlike other emerging layer 2 solutions for Ethereum, Zetachain has its own utility token. Zeta token is used to pay for transaction fees. This keeps gas fees relatively cheap on Zetachain and removes any dependance on Ethereum.

However, if an interaction with another chain has to be done, that part of the interaction has to be be paid in the native token. More information about the fees could be found on that page.

To facilitate the payment of transaction in the native tokens, ZetaChain uses core liquidiy pools. Anyone can contribute to the pools and earn fees.

How it works

ZetaChain is a ¬†Proof-of-Stake blockchain built on the Cosmos SDK and Tendermint Consensus. In order for ZetaChain to be able to interact with many blockchains, it needs to have an account on each chain. ZetaChain smart contract layer orchestrates the logic and if an interaction with an external blockchain has to be done, it will be done through this privileged account. This account can custody assets on that chain, mint tokens, burn and NFT to transfer it, etc… The concept is simple, however this has to be done in a decentralized manner without a single point of failure. For example, if any validator has access to the private keys of this account, it has full access to the assets and can compromise them.

To counter this, ZetaChain uses a multi-party threshold signature. In short, the private key is generated without a dealer and it is distributed in all the validators. So no validator can reconstitute the full private key and use it independently. So the generation of the key and the signing procedures are done by Multi-Party Computation (MPC) and no secrets are revealed to any participating node.

Risks

ZetaChain is a new blockchain that is still not battle tested. An extensive research should be done before investing in the platform.

Airdrop

ZetaChain is conducting a second round of its token airdrop. To participate, in the airdrop, you can complete simple tasks on ZetaHub and earn experience points that could make you eligible.

Where to get ZETA

Many centralized exchange offer ZETA coin. The token is available on MEXC. As of today, the cost of withdrawing ZETA from MEXC is 0.1 ZETA, which is reasonable. If you need to transfer the token on chain to experiment with the blockchain, make sure you withdraw on the ZETA network and that your offline wallet supports the ZETA chain. Only withdraw the ERC20 ZETA on the Ethereum network if you need it on that chain for some, however, this could be costly.
