1/7 🚀 Pearl FP8 development update
Several new PRs landed this week, focusing on FP8 quantization, jackpot security, and V4 prover performance.
The interesting part? Developers are still refining the consensus-critical details.
Let’s dive in. 🧵

6/7 🖥️ What about RTX 50-series?
The latest work includes B200-specific changes, but SM120 support remains unconfirmed for production FP8 mining.
RTX 5070 Ti, 5080, and 5090 miners still need reliable compatibility and performance benchmarks.

7/7 📈 My take: Cautiously bullish on engineering progress.
PR #311 remains open, PIP-3 is still Draft, and no FP8 activation height has been confirmed.
The real catalysts remain:
• FP8 mainnet
• Stable GPU support
• Working inference marketplace
• Real compute demand

its time to update the mainnet and release it in the form it was originally planned, the very first vision is probably the only correct one
special thanks to all the validators and participants who supported the devnet and continue to do so - now it's time for the mainnet, permission less access is planned for tomorrow/the day after (the exact time is unknown, any second now)
everything needed to run a mainnet node will be available in a separate release, thanks everyone – at London, England
🚀 #Pearl FP8 update
PR #467 (Speed up V4 prover) merged into fp8-scheme on Nov 5.
Another step toward production FP8 mining, following recent merges of #417 and #471.
⚡ Faster proofs
PR #467 includes 57 commits across 28 files, optimizing V4 prover performance, #Blake3, and STARK components.
Reducing proof overhead could improve mining efficiency and make FP8 more practical.

Proving an AI computation was performed and proving that the correct AI model produced the answer are two different problems.
@AnthropicAI addresses the second problem. @prlnet primarily addresses the first.
Big news from @AnthropicAI on verifiable LLM inference, with an exciting connection to Pearl’s proof of useful work.
Two orthogonal questions:
• Did the model you paid for actually produce this response?
• Was computational work performed?
Anthropic reports that generating inference proofs currently takes ~70–95× the GPU time of ordinary inference. Pearl’s PoUW, on the contrary, adds negligible overhead. These costs buy different guarantees. Proving correct inference doesn’t automatically establish proof of work and the other way around. But the two are deeply complementary. Verifiable inference could certify which model produced an answer, while Pearl׳s PoUW only certifies that a computation has been done.
As inference proofs get more practical, that combination could make AI easier to trust and more economical to provide.

🧵 I dug into Pearl’s new FP8 mining mechanism and its fp8-scheme code.
This isn’t simply replacing INT8 with FP8.
The design combines AI inference, deterministic noise, matrix multiplication, a tile-based mining lottery, and cryptographic verification.
Let’s break it down. 👇

For GPU miners, FP8 FLOPS alone won’t determine profitability.
What matters:
• Eligible lottery tiles/sec
• Valid proofs/sec
• Proof overhead
• GPU memory bandwidth
• Inference throughput
• Power consumption
Hopper & Blackwell are the target architectures.

Pearl’s FP8 design is ambitious:
Useful AI computation + a verifiable mining lottery.
The 4-row minimum and 16-lane extractor are confirmed in code. Commercial inference demand and production deployment still need proof.
