Sunday Brief – May 24, 2026
TatsuOS reached a major milestone this week with the smart-contract API frozen, core interfaces locked, CI and change-control finalized, and fuzz testing planned next.
At ChipForge, verification is one of the most important parts of the entire chip design flow. Miners finding bugs, fixing bugs, stress testing designs, and validators checking whether those bugs and fixes are actually real, that is what makes decentralized chip design possible in practice. A major part of the current effort is going into making that flow faster and more scalable. RVGEN continues improving the test-generation side of verification, while the agent-based validation pipeline is being developed to reduce manual effort in validating miner-submitted bugs and fixes. Together, both systems are aimed at significantly reducing development iteration time across the MCU and NPU roadmap.
Chip Design Team
- Work on RVGEN continued this week, with focus on improving both usability and deeper verification coverage
- Added directed cache-conflict generation support, allowing the generator to intentionally create memory access patterns that collide on the same cache sets and stress cache eviction and replacement behavior during verification
- The generator now includes explicit cache-conflict coverage tracking, further extending the overall verification coverage infrastructure
- Improved the command-line workflow, making it easier for verification engineers to quickly explore available tests, streams, and targets directly from the terminal without depending heavily on documentation
- RVGEN now passes over 1000 unit tests while maintaining full Spike validation across the internal regression plan
- Internal testing also shows very strong generation performance, currently running more than 10x faster than some SystemVerilog-based generation flows in comparable scenarios, though broader benchmarking against other widely used generators is still ongoing
- Work also continued around the agent-based verification pipeline discussed earlier, particularly around how it can be adapted cleanly for larger CoralNPU verification flows
- The long-term goal is to automate larger parts of bug triage and challenge validation, where miner-submitted tests and fixes can be analyzed, classified, and validated much faster with minimal manual effort, while still keeping the overall flow reliable and scalable
TatsuOS
- The smart-contract API is now frozen as the first major milestone
- The TatsuBurn contract interface, events, and receipt format are now locked to provide a stable target for firmware, signer infrastructure, SDK integration, and future auditing
- Completed full Hardhat-based test coverage for burn flow, feature registration, access control, and edge cases
- CI validation now runs automatically on every pull request before changes can be merged
- Dependency versions were pinned and stricter change-control rules were introduced around contract modifications
- Next phase will focus on property-based fuzz testing using Foundry and Echidna to stress deeper contract invariants and randomized transaction flows
Both the verification infrastructure and TatsuOS roadmap continue moving toward the same goal: building reliable systems that can scale without sacrificing correctness.
Sunday Brief – May 17, 2026
A delivery and foundation week. RVGEN officially launched as an open-source instruction generator, and the TatsuOS whitepaper was released with a detailed six-month roadmap.
Brief Summary
This week we moved from preparation to public release. RVGEN, the ChipForge instruction generator mentioned last week, is now live and available via pip. It's already surfacing real compliance bugs in external usage and strengthening our internal verification flows. In parallel, the team completed an initial end-to-end test of an agent-based verification pipeline designed to automate bug validation and challenge evaluation. On the TatsuOS side, the whitepaper dropped with a comprehensive technical breakdown and a tentative six-month roadmap. Both projects are accelerating toward faster execution.
Chip Design Team
- RVGEN officially launched under the Tatsu Github organization: `pip install rvgen`
- Source code available at https://t.co/lbToKKPD6s
- Modern chip verification depends on generating massive amounts of meaningful randomized programs while controlling corner cases, privilege transitions, vector behavior, traps, and mixed workloads — RVGEN was built to solve that problem
- Supports 29 built-in RV32 and RV64 targets covering scalar integer, floating-point, vector, compressed, cryptography, hypervisor, and newer RISC-V extensions
- Designed to be self-contained and easier to extend compared to existing flows, removing the need for large external riscv-dv setups
- Currently passes 989 unit tests and 213/213 Spike validation cases across the internal verification plan
- Already in use internally on both CoralNPU and ChipForge MCU; external adoption this week surfaced multiple real compliance bugs that have since been fixed
- Completed initial end-to-end test of agent-based verification pipeline to automate bug validation and challenge evaluation at scale
- Both RVGEN and the agentic validation flow are being built to support a much faster challenge cadence once the subnet returns
TatsuOS
- Released whitepaper outlining the full technical architecture and vision for the project
- Worked through technical details and complexities with the team, producing a comprehensive yet tentative six-month roadmap
- Moving forward, we'll be posting TatsuOS progress updates twice a week to keep the community informed as development accelerates
Una mujer graba en directo cómo DOS OKUPAS intentan entrar a la fuerza en una casa en España.
Cuando ven que los vecinos les cierran el paso, se giran y sueltan la frase:
‘RESPETO’.
PIDEN RESPETO
Esto no es okupación.
Es invasión con cara de víctima y chantaje.
Mientras tanto, el Gobierno les abre las puertas, les da subsidios, hoteles y pisos gratis con el dinero de los que sí pagamos impuestos.
España se está entregando y nos llaman fascistas por querer defender lo nuestro.
¿Hasta cuándo vamos a seguir callados?

Sunday Brief – May 10, 2026
A rebuilding and preparation week. Following last week's subnet deregistration, the team has shifted focus to strengthening the foundation — accelerating challenge creation infrastructure and advancing TatsuOS development.
Brief Summary
With ChipForge temporarily offline, we're using this time to remove bottlenecks and build faster. The chip design team is preparing the next challenge set while open-sourcing the ChipForge instruction generator — a tool that will dramatically speed up test generation and verification. In parallel, work continues on agent-based validation and TatsuOS development. We're building steadily toward re-registration with stronger infrastructure and clearer execution.
Chip Design Team
- Preparing next challenge set to launch once the subnet is re-registered
- Identified a major bottleneck: large-scale test generation and verification infrastructure for complex RISC-V workloads
- Developed ChipForge instruction generator to solve this — will be open-sourced before next Sunday
- Supports randomized instruction generation across scalar integer, floating-point, vector, privileged, and unprivileged modes for both RV32 and RV64
- Already in use internally for regression and stress testing on both CoralNPU and ChipForge MCU
- Continuing work on **agent-based validation pipeline** to automate larger portions of verification and challenge validation flow
- Goal: launch challenges at a much faster rate and accelerate development across NPU and MCU tracks
TatsuOS Development
We're also building TatsuOS — an IoT fleet management platform powered by $TATSU token economics.
Think: real hardware, real burns, real unlocks. Ethereum-based smart contracts managing embedded devices running trained AI models, with over-the-air updates and multi-MCU support.
Full roadmap and whitepaper dropping next Week. Stay tuned.
@RockSand1903@minds_eminent@philosophysage And even if your body screams: but what if? (It gets different/I can change something)
Its not worth it. There are women around that will treat you healthy and love you. You will see, looking back, how toxic it actually was.
@RockSand1903@minds_eminent@philosophysage You’re welcome. Long term this is the worst type of behavior you can experience. And it turns into abuse in the long run. I don’t wish that feeling upon anyone, because it’s real abuse and leaves trauma/marks.
@RockSand1903@minds_eminent@philosophysage Run brother, just run. You can not change anything, even tho it seems for a moment that things are different. They just to lure you in again to repeat the same toxic pattern. Breaking away is the hardest part because they will play the victim.
An Update on the Taτsu Ecosystem: The Path Forward
Our Subnet ChipForge has been deregistered. While our technology remains excellent—recently proven by our open contributions to Google's Coral NPU— we still were caught in the cycle of deregistration process.
High-end chip design is a sophisticated, capital-intensive field that demands advanced engineering and patience, but it offers unparalleled revenue potential in the long run. We are not slowing down; instead, we are refining our focus into two parallel tracks that leverage the full spectrum of our team’s capabilities.
Track 1: ChipForge — Our Main Focus
ChipForge remains our elite hardware design arm. Our work solving complex chip-design challenges through open competition is a core part of our identity. We will maintain ChipForge as our main focus, preparing for a return to the Bittensor ecosystem when the registration and economic environment align with our long-term hardware roadmap.
Track 2: TatsuOS — The Commercial Product
In parallel, we are accelerating TatsuOS, our AI-native IoT platform. While ChipForge pushes the boundaries of future hardware, TatsuOS solves the practical, commercial challenges of the IoT industry today—ending the "subscription trap" and vendor lock-in.
• Commercial Utility: TatsuOS enables "Burn-to-Unlock" features using the $TATSU token, granting users permanent, cryptographic ownership of their device features.
• Infrastructure Simplified: Managed telemetry pipelines, fleet-wide dashboards, and over-the-air (OTA) updates are standard, replacing three separate vendor contracts with one unified platform.
• The AI Agentic Pipeline: This is the heart of TatsuOS. We are democratizing Edge AI. Our platform allows anyone to turn an idea into a deployed model via Agentic pipelines. You no longer need a team of Data Engineers, AI researchers, or MLOps specialists.
◦ Example: "I want my soil sensor to detect water stress 24 hours earlier"—our AI agents handle the data engineering, model training, and deployment directly to your devices over the air.
• A New Home for $TATSU: This creates a direct, undeniable link between the token and real-world product usage across thousands of devices.
We are building both in parallel—one to design the chips of the future, and one to power the devices of today. We will continue to provide weekly, data-driven updates on both fronts.
The technology is solid. The strategy is clear. Let's hope for the best.

”You’re going to be attacked If you say Europe has been predominantly White for the entirety of its history, a few bureaucrats have decided against the will of the people that we should suddenly be a minority.
Why do we agree with that or why do we allow that to happen?
If you say that, you are going to be attacked. But the only other option that you have is saying nothing and have it happen, so the choice is yours”
We shouldn’t be silent, we must be brave and say what we really think.
