Earlier on September 28, Cortex successfully launched its fully-functional Mining TestNet - "Bernard" and a beta version of the Cortex AI Smart Contract TestNet - "Dolores". Bernard and Dolores TestNet are the first to enable AI inference on the blockchain to showcase to the world.
Cortex is the first blockchain project that allows the execution of AI algorithms on the blockchain, providing an AI platform for developers to upload their models on the blockchain that can be integrated with the smart contract.
"The AI smart contract is the much needed mind-blowing feature missing in all popular blockchains today. Moreover, AI models will be democratized and users will gain control of their own data and get incentives to compete with big corporations." posted Cortex
Mining TestNet:
Cortex block explorer - "Cerebro" helps users explore individual blocks and transactions, transaction histories, and address balances on the Cortex blockchain. The significant feature is that it allows users to add, explore, and invoke AI models via smart contracts to infer data, depending on the application. To use and interact with the Cerebro browser, you need to have Cortex wallet installed.

The company has deployed 10 full nodes distributing in 6 countries for its TestNet, to generate AI smart contract logs and inference results.
To let developers learn and interact with the TestNet Cortex team has also published a detailed testNet setup and walkthroughs on features of its TestNet.
"Cuckoo Cycle" Consensus:
The Cortex has implemented Cuckoo Cycle algorithm which is based on Proof of Work for network consensus and allows commodity hardware to mine. The team wanted to have one-machine-one-vote to allow more people to participate equally in the consensus.
AI Smart Contract:
AI smart contract can be written with Solidity, which is the programming language of Ethereum. Cortex’s CVM is backward-compatible with EVM but adds infer instructions. one can also use Remix to write AI smart contract. Developers can also upload their own AI models for inclusion on-chain.
