**#OPML**  
1⃣ Completed MIPS instruction set compilation for cvm-runtime & implemented the test model.

2⃣ Fixed MIPS dynamic library loading & adapted to tensor/data types of MLVM.

3⃣ Modified memory layout & adjusted model reading format to struct + weights; implemented data reading/writing logic for specific memory addresses.

4⃣ Adapted cvm-runtime model inference to support step functions.

5⃣ Added the Unicorn debug tool.

  

**#ZkRollup**

1⃣ Implemented execution for precompiles & removed static assertions.

2⃣ Input implementation completed for all circuits.

3⃣ Used grand products to prove queue equality.

4⃣ Sorted & deduplicated code decommit requests, added a code decompressor to unpack code into memory.

5⃣ Investigated & optimized Plonky3 compilation and runtime speeds.

6⃣ Researched FAST-VM & naive VM execution results, modified VM OP execution process.

  

**#Cortex Full Node**

1⃣ Removed unused parameter

2⃣ Added config option to disable FINDNODE liveness check

3⃣ Fixed minor issues in state DB snaps

4⃣ Fixed flaky tests writing to test.log after completion

5⃣ Added snapshots to state database

**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!
