Introducing Claude Fable 5.2 and Claude Mythos 5.2, designed to tackle the most daunting technical challenges.
They’re capable collaborators on ambitious projects in many fields, and show improvements in areas like coding, reasoning, and vision.

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.

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
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.

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.
Today we are proud to announce that Celestia Labs has acquired Sovereign Labs.
This acquisition establishes Celestia Labs as a full-stack custom blockchain development partner for companies building onchain, marking a new chapter for our go-to-market strategy and ambitions.

1/8 Today, we introduce CTR, the coordination asset for the Bitcoin economy.
Over the past two years, we built an end-to-end Bitcoin economy that relies on the Bitcoin Network as its source of truth.
With CTR, we're handing control of this economy to the people who use it.

We are proud to announce our $5.5M fundraise from Turkish giants FRWRD Ventures by @YapiKredi, @isportfoy alongside @circle_ventures @Consensys @ParibuCom @will__price @izebel_eth ahead of the launch of ITRY, offering ~45% APY backed by Turkish Lira MMFs, on April 20th.
Announcing Private Blockspace: built for high-performance onchain markets where confidentiality is a requirement, not a feature.
Positions, balances, and execution logic can remain private, while data availability and protocol commitments are designed to remain publicly verifiable.
