### Technical Updates 🤖

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

**MRT/CVM**

1.  MRT, TVM and Circom unified representation structure, where MRT uses built-in InferType and InferShape
    
2.  Add MRT operator to Circom's parser, and adapt to the shape adaptation of operators such as clip
    
3.  Increase the export of Circom input parameters. The tested resnet data input size exceeds 100M. Consider integrating some parameters into the ZKP operator to reduce input consumption
    
4.  Adjust the type check in MRT FixPoint, reduce TVM adaptation, and increase shaping check
    
5.  Increase the type annotation of MRT Symbol, adjust the representation structure, and enhance the readability of the code
    

**ZkRollup**

1.  The WitnessGenerator module adjusts some storage-related interfaces and adds merkle\_state to generate proofs
    
2.  Refactored the execution flow of StateKeeper: PendingBlock synchronously initializes StateKeeper and WitnessGenerator
    
3.  Implement the L1Watcher module to monitor the data on the chain
    
4.  Mempool handles unconfirmed events
    
5.  ZKSync - era research (supporting L2 smart contracts), newly open-sourced part of the code of the GPU prover
    

**Cortex Full Node**

1.  pepple MemTableStopWritesThreshold fix
    
2.  fix off-by-one in ipc endpoint length check
    
3.  some funcs added and fix about pee

**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!
