blockchains are not designed for humans. blockchains are built for autonomous AI agents, optimized for efficiency and precision. humans were merely the early adopters.
After 20 years at BlackRock and helping to lead its digital asset strategy, I’m beginning a new chapter: I’ve joined @SharpLinkGaming as Co-CEO. Here’s why. At BlackRock, I helped launch: - IBIT — world’s largest Bitcoin ETP - ETHA — world’s largest Ethereum ETP - BUIDL —…
Aztec and the EF are teaming up to embed privacy as a core value of our ecosystem. Without privacy, blockchain is a shadow of what it could be. What it needs to be. coindesk.com/opinion/2025/0…
Team is shipping - massive congrats @_ArnaudS_ @Zac_Aztec @jaosef @omw_to_the_moon @clairekart and rest of the team. @aztecnetwork fully decentralized, permissionless adversarial testnet is live and undergoing rigorous testing with slashing enabled 🤯 Spin up a node and join…
1/5 Aztec just entered a critical phase: Adversarial Testnet. The network is designed to be private and decentralized from day one. This phase is a key step toward launching the first fully decentralized privacy-preserving L2 network on Ethereum. aztec.network/blog/aztec-ent…
Honored to support World’s mission as a long-term security partner. Together, we’re raising the bar for privacy and trust.
Proud to partner with World from the earliest days. Delivering secure, resilient identity infrastructure together, and excited for what’s ahead.
Today, we celebrate @worldcoin’s remarkable progress in building secure, privacy-first identity solutions for the web3 era. Their commitment to reimagining digital identity continues to set new standards for trust and user empowerment. We’ve been proud to partner with World from…
Two years in, and our why hasn't changed: We're building World so every human benefits from the age of AI.
At Nethermind Security, we’re building infrastructure for formal verification of real-world zkVMs. We’ve applied our approach to R0VM by @RiscZero and SP1 by @SuccinctLabs, two of the most advanced zkVMs in use today. 1/
1/ Last week, we shared why continuous testing matters. Today, we’re zooming in on PerfNet, our internal testnet for safely stress-testing Ethereum before issues hit mainnet. 🧵
1/ Over the past months, we’ve: — Benchmarked opcode execution across clients — Built PerfNet to test performance under pressure — Simulated 1.5x mainnet state with @CPerezz19 & @gballet for early scaling tests Not for headlines, but to keep Ethereum resilient.
We shipped an Adversarial Testnet AND a product integration you can use, today. Use @ZKPassport to privately, permissionlessly join the validator set using your passport or national ID. Info never leaves your phone. The set of things *only possible* with @NoirLang and…

This is a huge milestone for us. Our testnet is now fully decentralised in any metric. I'm hugely proud of the work that went into this. We don't just talk at Aztec - when we say we're going to do something, we do it!

We just shipped the last major update to testnet before audits start and we turn our attention to mainnet. This testnet is permissionless — create a zero-knowledge proof of passport to join. This testnet is adversarial — nodes can slash misbehaving nodes. In the style of…

We're putting the network through ever more stringent tests. It will be launched properly: decentralised, permissionless, and reliable. Watch this space.

45M block has arrived. Moar 🚀
45MGas block proposed by BuilderNet(Flashbots) and accepted Ethereum mainnet block size and L1 throughput has increased 25% since last week! Moar
I am honored to be asked to be a torch bearer for the run up to the 10th anniversary celebration of Ethereum's launch and non-stop, essentially flawless, operation of the protocol -- even as the protocol underwent many major upgrades "in flight" – without missing a block.
The ticker is ETH
We are The Ether Machine. Today we launch the largest public vehicle ever built to own and manage ETH with over $1.5B in committed capital. This is Ethereum’s institutional chapter. Not passive. Not synthetic. Not outsourced. ⬇️
Welcome to the machine. ethermachine.com #eth #Ethereum
Solving scaling and interoperability challenges together. Solid start, look forward to seeing more partners joining @boundless_xyz
The Signal is an initiative supported across the industry by @base, @wormhole, @eigenlayer, @unichain, @LineaBuild, @build_on_bob, @NethermindEth, @StellarOrg, and @optimism. Together, we are creating a blockchain ecosystem connected by ZK.
🎙️New pod just dropped! I sit down with my old friend @StaniKulechov, Founder of Aave Labs, to deep dive into @aave v4 and its biggest updates compared to v3. This is Ep. 1 of a new series where I analyze the evolving architecture of onchain lending markets and their impact on…
Congratulations to the @boundless_xyz team on launching The Signal! An important contribution to the ecosystem’s shared mission of interoperability between rollups built on @ethereum.
Boundless Mainnet Beta is Live. With it, we are launching The Signal: an industry-wide collaboration to ZK prove all chains. A new era of scaling and interoperability starts now.
