This was easily the most interesting conversation I have ever had. Thank you, @Snowden, for your candor about cryptocurrency, financial privacy, and the mass surveillance of the traditional banking system. And thanks for hosting, @decrypt @EtherealSummit! decrypt.co/70049/bitcoin-mus…

AI needs somewhere to put all that data.
Marta Belcher joined me to explain why storage is becoming a bottleneck and where Filecoin fits into the picture.
Today's launch of Integral Spacetime is a huge moment for @Filecoin!

AI needs data. Who gets to control it?

3/ Why timing matters: the Senate is scheduled to go into recess on August 10. If CLARITY doesn't pass before then, it risks slipping past midterms. Bills with this much bipartisan momentum don't get many windows like this one. Senate Majority Leader Thune has pledged a floor vote before the August recess, as early as next week. This is a critical moment for innovation in the U.S.
Here’s PL’s @martabelcher explaining how critical the timing is for this bill.
Excited for @tomas_hk and the Not Diamond team! I love that prompts and code never leave the developer's machine, and no single vendor owns your stack.
Today we’re announcing Not Diamond Code, the world’s most powerful intelligent model router for long-horizon coding agents.
Not Diamond works with any gateway or harness, including Claude Code, to select the best model and reasoning effort for each step, reducing costs by 20-65% without impacting quality.

6/ In a world where almost everything you do runs through an online intermediary, the third-party doctrine swallows user privacy whole.
Here’s a video of PL’s @MartaBelcher talking about the issues with the third-party doctrine.

Yesterday, the Supreme Court ruled that people have a reasonable expectation of privacy in their location records stored by services like Google. This is a huge win for user privacy in the U.S.
Here’s why. ⤵️

250 years to download at 1Gbps. 70 Libraries of Congress. That's one exabyte.
Filecoin operates beyond that scale.
@IOHK_Charles explaining why exabyte-scale storage is internet-scale storage.

The world's largest decentralized storage network. Exabyte-scale capacity.
Production-grade infrastructure that is hard to replicate.
@MartaBelcher on what Filecoin has built over five years on mainnet, from a conversation with @IOHK_Charles.

Cardano's @IOHK_Charles and @FilFoundation President @MartaBelcher chat about how @Cardano utilizes Filecoin's EiB-scale infrastructure, how the Filecoin Onchain Cloud brings a programmable storage and payments layer to developers, Filecoin's 2026 focus on enterprise-ready products, why Filecoin is made for the AI era, and why decentralized storage is the "last mile of decentralization" for Web 3 projects.
Loved having this conversation with @IOHK_Charles about the many ways the Cardano and Filecoin ecosystems are collaborating!

The 2026 Filecoin Network Strategy is live.
After five years expanding storage capacity to exbibyte scale, the network is shifting from adding supply to increasing paid, onchain storage deals, improving incentive design, and onboarding customers running production workloads.
