Technical Updates 🤖

Machine-Learning(ML), CortexVirtual Machine(CVM) & Model RepresentationTool(MRT) R&D

Update the MRT documentation, and improve the introduction and quantification of mnist-tutorial

Zk Rollup

1. ZkContract refactors the code, adjusts the processing logic and reduces the size of the compiled bytecode of the main contract;
2. ZkContract adds contract-related functions (event, etc.) required for Layer 2 to restore the state;
3. ZkContract modifies the logic of the deposit to ensure that the deposit is not tampered with;
4. ZkContract adds full-exit to provide a safe exit mechanism when the operator is not trusted;
5. The GPU version of ZKProver fixes the problem of too much CPU calculation and too much resource usage;
6. ZkNode updated the submission logic of ctxc-committer and fixed the Merkle root error of L2 block submission under multi-process;
7. ZkNode JS updated simulation data generation error, added Nonce cache mechanism, and fixed other problems;

Cortex Full Node

1. Add Web3 JS test code to full node tx-carried mode;
2. Ethereum beacon chain investigation;
3. Add final & early block API;
4. Rework & dependent preimage store func;
5. Lazy queue & sim clock & simple stack added;

About Cortex 😇

Cortex’s main mission is to provide state-of-the-art machine-learning models on the blockchain in which users can infer using smart contracts on the Cortex blockchain. One of Cortex’s goals also includes implementing a machine-learning platform that allows users to post tasks on the platform, and submit AI DApps (Artificial Intelligence Decentralized Applications).

Cortex is the only public blockchain that allows the execution of nontrivial AI algorithms on the blockchain. MainNet has launched. Go build!
