In March, Google Quantum AI proved a record breaking quantum circuit existed, while the implementation was not made public. What they released instead was a proof that the circuit exists. And that can be verified: a program that tells you whether a candidate circuit is correct and what it costs. Which left anyone free to build their own and test it against Google's number.

The Privacy Frontier: ZK meets TEE Most privacy panels explain why privacy matters, this one is two builders comparing the opposite bets they made. With @MayaDotan_ (StarkWare) and @AlexAuroraDev (NEAR), moderated by @jessiexiao_eth. Tomorrow, 1:00 PM GMT. Hosted on @Starknet.

Bitcoin <> Starknet bridging: status update Atomiq, one of our Bitcoin bridging providers, is currently offline following a security incident on their infrastructure. As a result, Bitcoin bridging to and from Starknet is currently unavailable. Users with a swap in progress can recover funds directly via Atomiq's site, which remains accessible. Swap funds are held in escrow, not by a third party, and remain recoverable regardless of Atomiq's service status. Bridging between Bitcoin and Starknet will be restored within the next few days through a new integration we are onboarding. Full details will be shared once it is live. An update will be posted once bridging has resumed, or sooner if there is a change to share.

One of the Bitcoin community’s top priorities should be achieving post-quantum security as soon as possible. It’s already a top priority for us. And Starknet will be post-quantum secure by 2027.

We spent H1 expanding what you can do onchain: • Move USDC privately • Private + productive Bitcoin via strkBTC • One-click privacy for any asset in your wallet • Made Starknet agent ready via @StarkscanCo • Account abstraction-powered apps via Starkzap Starknet.

1/ The Private Sprint is in full swing on Starknet. And it's showing one thing clearly: anyone can now build pretty much any private app they have in mind, with the tools and support they need. Here's a sample of the projects being built on top of STRK20s 🧵

1/ Q-Day is the day cryptography stops being secure. The moment a quantum computer becomes powerful enough to break public-key cryptography, every modern blockchain faces a problem it was never designed for. And most people still have no idea how close that day may be 🧵

STRK20s ┣ Privacy for every ERC-20 (✅) ┣ Private payments powered by @avnu_fi’s paymaster (✅) ┣ Private swaps on @avnu_fi (✅) ┣ Private liquid staking with @endurfi (✅) ┣ Private lending and borrowing with @vesuxyz (⌛) ┣ One-click shielding with @ready_co and @xverse (✅) ┣ Privacy-powered yield generation with @trovesfi (⌛) and @ForgeYields (⌛) ┣ Private stablecoin minting with @OpusMoney (⌛) ┣ z402 for AI agents (⌛) Privacy for everything. On Starknet.

Chance, now live on Starknet. AI agents are increasingly being trusted to move money. Chance prevents agents from hallucinating with your money. Before an agent transaction executes, Chance simulates the exact action and checks it against the user’s mandate. If it does not match, it is blocked before funds move. On Starknet, Chance uses programmable escrow wallets. Agents can propose transactions, but funds only leave escrow when the proposed action satisfies the user’s mandate. Additionally, Chance will use Starknet’s privacy framework, STRK20, to keep an agent’s mandate and settlement context private, while allowing receipts to be selectively disclosed when needed. This is what Starknet enables for the agent economy: agents can act, but users keep control of the rules, the funds and what stays private. Welcome, @Chance_

“Today, if you want a shielded version of Bitcoin, it’s very hard to find one.” - @EliBenSasson On Starknet, that Bitcoin already exists. strkBTC can be shielded for private transfers, private swaps and now private liquid staking. Bitcoin that is private and productive.

Starknet is uniquely positioned to become fully post-quantum secure. And now you can verify why. Explore our migration, breakthroughs, and research in the Starknet Post-Quantum Hub.
