2/Where we're headed: ➡️ Full LLM support ➡️ MRT lower architecture refactor in 2026 ➡️ Next-gen CPU/GPU runtime upgrades We're bridging AI and Web3 to create trustworthy, transparent intelligence.

1/Over the past 6 months, Cortex has been building the foundation for Verifiable AI. What we've achieved: ✅ Unified TVM & PyTorch frontends in MRT ✅ Advanced our ZKP/ ZKML research with EZKL, Taiko ✅ Built a deterministic runtime for verifiable inference

🛠 Cortex Full Node Updates – #131 🛠 New fixes, optimizations, and a fresh stable release 1.10.63 are here! Let’s break it down 👇 1/ P2P Enhancements 🌐 Discovery startup error handling improved (github.com/CortexFoundati…) Configurable discv5 response timeout for better network stability (github.com/CortexFoundati…) Unused parameters removed in revalidationList for efficiency (github.com/CortexFoundati…) 2/ Performance & Stability Tweaks ⚙️ Flush offset introduced in the freezer (github.com/CortexFoundati…) Fixed marshaling of NAT in TOML (Fix (github.com/CortexFoundati…) Skip setting flushOffset in read-only mode for optimized disk usage (Commit (github.com/CortexFoundati…) 3/ VM & Gas Optimizations 🚀 Intrinsic gas fix with bytes count for better gas computation (github.com/CortexFoundati…) Updated VM contract specifications (github.com/CortexFoundati…) 🔥 Cortex Full Node v1.10.63 Stable is now LIVE! Check it out: 🔗 Release Notes (github.com/CortexFoundati…)

4/ 🧠 What’s next? We’re pushing forward with decompilation tools, ZK circuit optimizations, and expanding our node features. Stay tuned for more updates! 🌟 🔗 Dive deeper into our progress: github.com/CortexFoundati…

3/ 🌐 Cortex Full Node Updates New releases: 1.10.63 unstable github.com/CortexFoundati… 1.10.62 stable github.com/CortexFoundati… Key improvements: Faster memory writes. DNS resolution for static nodes. Fixed encoding/decoding bugs.

2/ ⚡ ZkRollup Progress VM Cycle circuit implementation passed testing & ready for merge. 🎯 Updated scheduling logic: smooth, efficient, and almost complete. 🔄 Researched high-performance ZKVM code with unified execution interfaces and performance boosts. 💻 AWS migration completed for critical services like ZkMatrix, NFT platforms, and more!🌐

1/ OPML Development -Enhanced memory handling to prevent overwriting during compilation. ✅ -Successfully parsed startup.s, modified page_size, and recompiled. 🔧 -Integrated Unicorn with the Gapstone decompiler & debugged using Capstone 4.0.2. 🦄 -30%+ instruction parsing success in Optimism assembly. 🔍

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(github.com/CortexFoundati…); 2. replace custom logic with bytes.HasPrefix(github.com/CortexFoundati…); 3. release 1.10.62 unstable(github.com/CortexFoundati…); 4. release 1.10.61 stable(github.com/CortexFoundati…); 5. chore: remove redundant words in comment(github.com/CortexFoundati…);

🚀 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 github.com/CortexFoundati… 2. Reduced unnecessary JS bigint compilations github.com/CortexFoundati… 3. Simplified MaxUint64 github.com/CortexFoundati… 4. Fixed missing state when num is zero github.com/CortexFoundati… 5. Restructured dependencies on header github.com/CortexFoundati…
