Huge congrats to Succinct’s Rahul Dalal, one of the cryptographers behind FlashProve, @AnthropicAI’s provable inference system built on zkSNARKs.
Why: Today, AI runs on a “just trust me” model. Users can’t verify that a response came from the model they chose, or that an attacker didn’t tamper with it along the way. As AI takes on higher-stakes work, that create tension for users, labs, and regulators alike.
What: Researchers from Anthropic, EPFL, MIT, and @SuccinctLabs built FlashProve, a system that lets a model provider commit to a specific model and then prove each response was produced by it, without revealing the weights. Under the hood, it uses zkSNARKs, the same cryptographic technology Succinct uses to secure $13.5B in deposits on Ethereum L2s.
So What: FlashProve proved Llama 4 Maverick, a 400B-parameter LLM, at 110 tokens/sec on a single H100 GPU, with ~19 MB proofs. That puts proving at roughly 70 to 95x the cost of running the model. The previous standard for the same model was ~0.02 tokens/sec.
What’s Next: FlashProve is still a research prototype, but it’s a step change toward the question we asked with Flock earlier this year: how close can proving get to computing? The closer it gets, the less reason there is to release any output without a proof attached.
Congrats again to Rahul and the FlashProve team, and great to see @Starknet, @Mantle_Official (proven by Succinct), and several zkML projects cited.

Fibre is now live on Celestia mainnet, and Tensile is live with it.
Tensile is a real-time explorer for Celestia Fibre. It shows each blob as it lands, along with its fee and endorsers, and checks whether validators continue serving the data they endorsed.
Congrats to @celestia on bringing Fibre to mainnet.

Every transaction @Visa processed in FY2025 would fit into just over two minutes of @celestia Fibre throughput.
Celestia Fibre averaged 3.07 Tb/s over a 143s end-to-end run across 120 validators, enough data for nearly 2B tx/s by Celestia’s estimate
the number is wild, the path to it is more interesting ⤵️
A prospective customer with extreme throughput requirements asked how much capacity Fibre can really deliver. So we ran an end-to-end benchmark across 120 validators.
It sustained 3.07 Tb/s of throughput, enough data for nearly 2 billion transactions per second. Every transaction Visa processed in 2025 would fit in just over two minutes.

4️⃣ Fibre had already hit 1 Tb/s earlier this year, but that was a partial benchmark focused on the networking layer. This time, with those bottlenecks pushed back, they tested the full production pipeline from fresh blob generation and encoding through distribution, storage, validator signatures and finally the onchain commitment
over the full 143s window: 3.07 Tb/s
best rolling 60s: 3.69 Tb/s
best rolling 30s: 4.27 Tb/s
the throughput figures count only blob payloads whose Fibre publications were confirmed onchain. recovery pieces and the traffic used to distribute them were excluded

5️⃣ This isn’t @celestia mainnet doing 3 Tb/s today though. the benchmark used 2 GiB blobs, 1s blocks, 2,000 submissions per block and machine-specific tuning, running the production pipeline from an experimental performance branch. initial mainnet blobs are planned at 128 MiB
what i like here is that 3 Tb/s didn’t come from one magic optimization. every time they made one part fast enough, something else became the limit: encoding, then the chain, then storage
pretty bullish on Fibre after this. definitely one I’ll be watching closely as it moves toward mainnet

Celestia continues to push the frontier of onchain scale with Fibre, hitting the equivalent of 2B TPS and 3x'ing our January bench
Two key differences this time:
1. We ran this at the request of a prospective customer
2. This was an end-to-end production benchmark
Huge result

new rollup, who dis?
so much more from our team on this side, were having a lot of fun cooking right now.
New case study: Midnight Network is using Celestia's data availability layer as a replacement for peer-to-peer networking, not just for storage.
The result for Midnight was shared liquidity by default. Every Zswap offer lands in the same namespace, readable by any wallet or app. New venues launch with day-one liquidity instead of bootstrapping traders individually, and privacy is preserved throughout via Zswap's confidentiality guarantee.
there is a lot happening under the hood with Zcash right now
Ironwood is live with a new shielded pool, while Tachyon is exploring a new path for scaling privacy and reducing quantum-vulnerable assumptions
@mert + @zkDragon live now on @therollupco with @andyyy & @robbieklages
worth tuning in

interesting shift from @BoundlessHQ
access to open-weight models is one thing. making them work efficiently in production across different workloads, latency targets and traffic patterns while keeping costs under control is another
what stands out to me is the focus on depth over model breadth. going deeper on the serving path and shaping it around what each workload actually needs feels like the right direction
a meaningful shift in where Boundless is heading with this next chapter
interesting direction from @KaitoAI
social reputation has mostly been about what people say online. Pulse + Aura brings what people actually do into the picture too
curious to see where this goes
get started: s.kaito.ai/9D4S3M
Introducing Kaito Pulse – a social layer for the internet, starting with X.
The internet was built around what people post.
It's now increasingly shaped by what people build, trade and back. Most of that never reached the timeline.
Until today: kaito.ai/aura
