 `CertiK Chain` is the key component in CertiK's vision of building end-to-end secure and trustworthy infrastructure for the blockchain world. Here is a brief [introduction](https://medium.com/certik/introducing-the-certik-chain-26629248da3c) to the chain.
 
-The first version of `CertiK Chain` is the testnet, which will go through three stages: closed alpha, open beta, and full testnet. The overall goal of testnet is to define and implement a majority of the `CertiK Chain` features and build a strong `CertiK Chain` developer and user community by providing opportunities to contribute to the chain design and development, to evaluate the chain's main features, and to develop smart contracts and other usage scenarios around the chain.
+The current version of the testnet is Incentivized Testnet, which anyone can participate to earn real CTK when we arrive at mainnet.

 As testnet moves through its various stages, CertiK Foundation expects to provide ample opportunities for active members of the community to be rewarded for their contributions.

 During this stage, testnet backend and frontend are exepcted to receive on-demand updates. Branching instead of re-deployment will be preferred when solving chain divergence. The validator set size will be large (e.g., no more than 100).
