Enterprises coming to onchain, but there's one missing piece: compliant privacy. Today we are unveiling Privacy Boost, onchain privacy SDK for enterprises. Scalable, compliant, self-custodial. Now live on OP Mainnet, and becoming the first privacy offering for @Optimism.

🔥 WHIR has landed in Plonky3 🔥 We just released v0.6.0, and with it we open the door to the world of multilinear PCS! 🚀 We've also shipped a ton of cool new features and performance improvements. 👀 Spoiler alert: Circle STARK is now *really* fast. github.com/Plonky3/Plonky3

And just like that, ERC-4337 is final 🎉 eips.ethereum.org/EIPS/eip-4…

But state diff rollups has raw tx data in the nodes, no? The exploit case only makes sense if the sequencer is not publishing blocks to nodes - malicious operator case. Wouldn't it be the same in Tempo Zone? If the Zone operator is malicious, can you debug the exploit inside?

Five exchanges. One OP Stack. Coinbase, Kraken, OKX, Upbit, Bitpanda. Different products, different markets. Same chain stack. $495M in application revenue across these chains in H2 2025.

Token Frameworks are now live on L2BEAT! A dedicated place to explore this specific category of interoperability solutions. You can see which frameworks are dominating the space (spoiler: OFTs) which are moving the most volume, how fast, across which chains, and for which tokens. Here's what these frameworks are, why they matter for risk, and what the data is telling us 👇

How Privacy Boost helps OP Enterprise serve institutional clients ↓ OP Enterprise gives fintechs, exchanges, and financial institutions managed OP Stack infrastructure. Privacy wasn't part of the OP Stack's original design, and for institutional use cases that's a gap worth closing. @sunnyside_io , as Optimism core developers, built Privacy Boost to close it. OP Enterprise clients get priority integration support. What enterprises get: • Traditional-finance-grade privacy: Sender, receiver, and amount shielded on-chain — just like traditional payment rails. • Compliant by design: Transactions hidden from the public, fully auditable for AML and other compliance requirements. • Drop-in SDK: No migration to a new chain. Existing finance apps can add onchain features without a rebuild. • Finance-app performance: Fast enough that your existing users get the same experience as the services they already use. • Self-custody: Users hold their assets directly — no platform or operator risk. Try it on @Optimism Mainnet and @soneium .

For the first time, all ZK circuits used by Lighter perp DEX L2 were regenerated from sources by L2BEAT! Now you don’t have to trust the Lighter team to perform a permissionless emergency exit. 👇Learn more in the thread👇

Proud to join Pacific Meta's Global Blockchain Partner Solutions as the sole privacy solution. Japanese enterprises and users deserve to transact onchain without exposing every move to the public. That's what Privacy Boost brings. Let's build 🇯🇵

Many people have claimed that with AI-assisted bug finding, secure code (and hence trustless anything) will be impossible. I have a much more optimistic take, and AI-assisted formal verification is a major part of the reason why: vitalik.eth.limo/general/202…

4/ What is Institutional-Grade Blockchain Privacy? Researched by @StackDigest from @PrivacyBoost x.com/FourPillarsFP/status/2…

Adding private payments to your app is way easier than you think. If you've wanted to let your users send tokens without revealing them to anyone else, Privacy Boost can enable the whole flow without having to write a single ZK circuit.

What is Institutional-Grade Blockchain Privacy? The @FourPillarsFP report featuring @privacyboost, the first privacy solution on the OP Stack, answers this.

Privacy Boost is featured in @FourPillarsFP 's deep dive on institutional-grade blockchain privacy. A decade of privacy tech has solved parts of the problem. None has yet solved all of it on a public chain at production performance.

My first article on @FourPillarsFP 🙂 If you are into privacy technology for institutions, please give it a look!

: : What is Institutional-Grade Blockchain Privacy? Blockchain privacy is no longer a question of how much can be hidden. The real question is what kind of privacy can survive contact with financial regulation. For public blockchains to become institutional financial infrastructure, they must support a new balance: - privacy by default - auditability by authorization - self-custody by design.
