In hindsight none of it was clear or a straight line. Really proud of our team and the grind of the past few years.

@oskarth @ethstatus Congrats!!

Yesterday was my last day at the Ethereum Foundation. Today we are launching EthSystems. We build confidential systems for institutional Ethereum. I've spent close to a decade building privacy infrastructure in crypto: p2p messaging at @ethstatus, developing Waku protocols at Vac (both now part of @logos_network), mobile proving tooling with @zkmopro, teaching zero-knowledge proofs with my zkintro primer, and advising @ethereumfndn on privacy and access layer strategy. Most of that was aimed at individuals. The past year at EF's Institutional Privacy Task Force (IPTF) we've been looking at privacy for institutions. On the surface this might seem different, but there are a lot of similarities. There's also a very strong market need for it, and the timing is right. I've written in the past about the tension and overlap between cypherpunks and institutions. Twitter is not exactly the best medium for nuance, but right now we are at a sensitive point in time: the defaults for the next generation of financial infrastructure are being set, with or without us. I believe we need cypherpunks in the room when that happens. Excited to start @eth_systems together with my co-founder @motypes and @_rymnc as part of the founding team. See quoted announcement thread for more details. x.com/eth_systems/st…

@Sharplink @eth_systems @BitMNR @ethereumJoseph Nice !

Sharplink has anchored the launch of @eth_systems, alongside @BitMNR and @ethereumjoseph, to build the technology that makes best-in-class privacy a standard on Ethereum. On a public ledger, the default is full exposure, which does not work for all financial institutions. That’s why this work is so critical. globenewswire.com/news-release/2…

BTW this was a huge USDG to tTSLA swap on @RobinhoodCrypto !🛡️ 🪶

Privacy shall protect users, not endanger them. Bermuda is built to protect you. @JphFritsche has written about it in Newsweek.

Something BIG just happened here 👀 explorer.testnet.chain.robinhood.com/tx/0xf9659ea69…

@alignedlayer money should move privately at internet speed.

money should move at internet speed.

Just finished reading a piece on what @LineaBuild & @bermudabayzk are building together and it got me thinking A lot of people assume the endgame for tokenization is simply putting assets onchain, the harder problem is what happens after that... Institutions aren't all going to operate on the same chain tbh, banks, funds, custodians and payment networks will all have their own infrastructure, their own compliance requirements and their own privacy constraints If that's gonna happen for real then interoperability becomes one of the most important pieces of infrastructure in the stack. What's interesting here is that they're not choosing between privacy and connectivity, they're trying to solve both at the same time To me, that's a far more compelling direction than another chain claiming it's faster or cheaper In the end, the real prize it's becoming the rails they move across

Some thoughts on atomic DvP. A difficult name for a simple principle many banks already use ledgers such as @Besu_eth (built by @Consensys 😎), but the problem begins when the asset sits on one network, the cash sits on another & both must settle without exposing positions counterparties or pricing @LineaBuild (@florian_huc & @goinfrexeth) with @bermudabayzk demonstrated atomic DvP across private or public evm chains. Linea enables the DvP between chains, while bermuda's privacy pool keeps sensitive transaction data private, even when the chains are public! both legs complete together or neither happens. no "half-settled" trade, no principal risk between the legs & no prefunding because the infrastructure cannot coordinate something important to understand: private chains protect confidentiality within their own perimeter, but the challenge begins when institutions needs to transact across different networks, especially when one of them is public this architecture connects private or public chains while letting institutions control what is disclosed, to whom & under which rules (very important for them) this extends beyond tokenized securities, the same model extends to FX, collateral, repo & regulated access to public markets the future of finance won't run on one corporate chain but across many private and public Ethereum ledgers coordinating without leaking sensitive data very happy to work alongside such talented builders across @Consensys @LineaBuild @Besu_eth if you have questions about any of this, drop them below and i'll be happy to answer

Bermuda 🤝 Programmable Compliance Looking forward to many great collaborations.

@Cointelegraph totally support this

⚡️ NEW: Ethereum validators could redirect up to 10% of staking rewards to fund ecosystem projects under a new proposal.

@0xhalloc Thank you for your attention to this matter!

Lol

@Egichzz 👀

$2.2 trillion a day in FX still settles with one side exposed to principal risk. not a legacy footnote. today's number, straight from BIS the reason it's unsolved: atomic DvP across different ledgers with privacy was always either/or. you got interoperability or you got confidentiality. a fully private chain solved secrecy by cutting itself off from everyone else Linea and Bermuda just demoed a PoC that breaks that tradeoff. tokenized security on one side, tokenized cash on the other. both legs settle atomically or neither does. details invisible to everyone including the operator, still cryptographically verifiable by whoever needs to check now line it up. SWIFT is running a blockchain pilot on Linea with BNP Paribas, BNY Mellon and over a dozen more banks, chosen for its zk privacy architecture Lineth is the rail. Bermuda is the privacy layer. SWIFT is the distribution the pieces are assembling in public and most people are watching a football tournament instead

Really excited about this one! We just built private cross-chain DvP with @LineaBuild. Two legs, two chains, one atomic settlement. Amounts and counterparties stay private. This is just the start 🚀

The institutional blockchain stack just got an upgrade. Together with @LineaBuild, we show how ZK is a natural enabler of locally controlled, globally accessible, and efficient on-chain financial markets.

Bringing institutions onto public infrastructure runs straight into one problem: privacy. He's building for exactly that. Alexander Wilke is co-founder of @bermudabayzk, building private rails for onchain assets like stablecoins and tokenized real-world assets. His work centres on letting these assets stay private while still enforcing policies, with custom issuer policies and compliance built in, so settlement such as DvP, PvP, OTC, and cross-border payments can happen privately on public chains. Institutional Web3 won't scale without privacy that works on open networks. That's what he's building. Join us in Berlin: luma.com/pb46re0a

We're pleased to welcome @bermudabayzk as a sponsor of the Institutional and Policy Forum. Bermuda is the privacy layer between enterprises and Ethereum, adding the privacy and compliance institutions need to go on-chain. Their support helps bring together policymakers, institutions, and builders for the conversations shaping institutional participation in public networks. 15 June 2026 · Organised by @EuEthInstitute and @SecurityOak

Just out of interest: how is Veilnyx actually different to other zk privacy protocols? "No hidden supply inflation" is enforced by your circuit. If there's a bug and someone makes a valid proof for notes worth more than they consumed, nothing flags it. So how would selective de-anonymization know which transactions to check?

This is exactly why privacy without verifiability is a ticking time bomb. Orchard’s design hid the exploit for 4+ years… and now no one can prove it was never used. At Veilnyx, we built privacy that scales with compliance, full confidentiality for users, but provable integrity for the network. No hidden supply inflation. No “trust us” moments. True privacy doesn’t mean flying blind.

The worst case scenario for $ZEC just became reality 🚨 - vulnerability discovered inside Orchard - Zcash’s main shielded pool active since May 2022 - remained unnoticed for more than 4 years - discovered on May 29, 2026 by security researcher Taylor Hornby - using Claude Opus 4.8 as part of the review process the vulnerability - could create counterfeit ZEC - unlimited amounts - completely undetectable inside Orchard Taylor reportedly built a working exploit - generated counterfeit ZEC - successfully tested it - exploit considered real the problem - Orchard is private - privacy hides transaction details - privacy hides balances - privacy hides supply flows which means - nobody can prove the vulnerability was never exploited - nobody can prove counterfeit ZEC was never created - nobody can prove the circulating supply was never affected even the Zcash team admits this “There is no definitive way to determine whether exploitation occurred.” the Zcash team is now discussing - a new shielded pool - migration away from Orchard - turnstile accounting - supply verification mechanisms - formal verification of Orchard Probably one of the most frightening vulnerabilities ever discovered in a privacy coin.
