Cortex Full Node v1.10.63 Stable is now LIVE!

Here’s what we’ve been working on last month in #OPML, #ZkRollup, and Full Node Development. 🛠

🧵👇

🔻Cortex Project Updates #129

#OPML

1. Parse the PC instructions executed by cvm-runtime mips and obtain binary code;
2. Research and debug capstone decompilation procedure and no-memory overflow segmentation fault;
3. Use c++ compilation and execution to test golang code;
4. measure c++ compile flag: softFloat, hardFloat, -O3, -mfp32, etc. And analysis readelf file for cannon;
5. Analyze and compare segment headers;
6. Research FHE releated project and technique;

#ZkRollup

1. add all the lookup tables used in the main VM circuit;
2. init the bootloader state;
3. add the register**,** add the witness oracle;
4. Refresh the state before each op execution: create a draft candidate for next VM state;
2. Implement the op circuit: impl add & sub opcode circuit**, **add the binop circuit**, **noop op circuit;
3. Basically complete the logic of all VM OPs (except for the ret part), test and merge into the cycle running circuit;
4. Study and merge the latest upstream code (some warehouse public archives, integrated), and prepare to gradually cherry pick the commits into the new fork integration library;

#CortexNode

1. transaction index independent & fix(https://t.co/UMxDbBMYtE);
2. replace custom logic with bytes.HasPrefix(https://t.co/0FEcK5SLO0);
3. release 1.10.62 unstable(https://t.co/WeWaSeoN44);
4. release 1.10.61 stable(https://t.co/FOgJf3hK3K);
5. chore: remove redundant words in comment(

🚀 Cortex Project Updates #128

#OPML
1. Solved issues with Unicorn executing cvm:
- Recompiled MIPS dynamic libraries and ELF executable.
- Mapped file system to specific memory addresses.

2. Developed program test steps, rewrote compilation script, parsed C++ results from ELF file.
3. Deployed cvm-runtime to MLVM Unicorn for execution, obtaining checkpoint_final and investigating specific instructions.

#ZkRollup
1. Implemented input across all circuits.
2. Used grand products for queue equality proof.
3. Sorted & deduplicated code decommit requests; added code decompressor for memory unpacking.
4. Processed log queue into specific queues, sorting L1Message logs and storage requests.
5. Built circuit for main VM.

#CortexFullNode
1. Optimized prefetcher heap escape
https://t.co/BeXBq0Iv5x
2. Reduced unnecessary JS bigint compilations
https://t.co/LTOElTS3lj
3. Simplified MaxUint64
https://t.co/55MiFR2kOw
4. Fixed missing state when num is zero
https://t.co/XW1MKm8XJm
5. Restructured dependencies on header

we would like to register one http://cortexlabs.ai emails to manage Cortex's self-reporting dashboard on CoinMarketCap.

1/🚀 Cortex Project Updates #127🚀

#OPML
1️⃣ Completed MIPS instruction set compilation for cvm-runtime & implemented the test model.
2️⃣ Fixed MIPS dynamic library loading & adapted to tensor/data types of MLVM.
3️⃣ Modified memory layout & adjusted model reading format to struct + weights; implemented data reading/writing logic for specific memory addresses.
4️⃣ Adapted cvm-runtime model inference to support step functions.
5️⃣ Added the Unicorn debug tool.

1/Cortex Updates #125

OPML
1️⃣ Researched the cannon arbitration process and analyzed the underlying processing logic.

2️⃣ Analyzed the technical route of ora-io OPML: implemented MIPS tensor op calculations with mlgo and preimage API with mlvm.
