1/ Our quantum-safe Bitcoin transaction cost ~$320 in GPU compute. Can you bring that down? Today, we’re launching the Quantum-Safe Bitcoin Autoresearch Challenge in partnership with @yukonresearch and @eigenlabs. Over $20,000 in rewards for improving the code:

Bitcoin and Ethereum’s quantum threat is getting harder to ignore. In roughly two months, 100+ participants and their AI agents drove down the estimated cost of the arithmetic of a potential quantum attack on elliptic-curve cryptography. Their work is detailed in the new paper, with seven co-authors from StarkWare and the Starknet Foundation. The challenge focused on a calculation that a sufficiently powerful quantum computer would use to recover private keys from exposed public keys. The result: an 86.1% reduction from the challenge’s starting resource score, which combines logical qubits and key computational operations. That score was also over 50% below Google Quantum AI’s reported result for this calculation, although the circuit setups and measurement methods differ. In simple terms, algorithm improvements can reduce the resources needed for an important part of a quantum attack. For StarkWare, this complements our broader work on quantum security in blockchain, from STARK proofs and Starknet’s post-quantum roadmap to our successful quantum-safe Bitcoin transaction on mainnet. We’re helping measure the threat and build the defenses. Congratulations to our seven co-authors across @StarkWareLtd and @StarknetFndn: @odin_free, @8am1am, @franklyteddy, @akashneelesh, @0xLucqs, @robertkp13, and @tarekeleter, alongside the wider community. Read the paper:

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.

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 🧵

Millions of ERC-20s have been created, and now any of them can be encrypted on Starknet. 34 are already moving privately, all sharing the same privacy pool. Pivot to STRK20s.

10 reasons to build on Starknet: 1. Native privacy for every ERC-20, every use cases, and every chains 2. Private DeFi with shared liquidity 3. The lowest privacy fees in the industry 4. Closer than ever to end-to-end post-quantum security 5. Formal verification deeply embedded across the stack 6. Cairo-powered provable compute 7. The most advanced ZK technology (STARK) and stack 8. Massive onchain compute 9. Native account abstraction 10. One of the wider offering of RWA markets (Perps)

STRK20s for all assets, all use cases, and all chains. Anyone can now bring privacy to any product, anywhere in the space. OffMarket is already showing what that looks like on top of Polymarket, and more are coming.

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.

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.

Shipping season never ends 🥷 1⃣ Native privacy for all assets is now live on Starknet - STRK20s is fully live on Mainnet, a privacy pool integrated at the protocol level, finally bringing practical privacy onchain: the lowest privacy fee on the market, fast UX, one-click at the wallet level, deep DeFi integrations, and the same liquidity as public markets, for all ERC-20s - As of today, you can shield, unshield, and access private swaps directly from Ready and Xverse wallets. - The ecosystem is already leveraging it: private USDC flows highlighted by Circle, 2 PoCs built by StarkWare (private Payroll and private KYC), and Zylith, a new call auction dark pool built on top of STRK20s. - For builders: the privacy SDK will be open-sourced very soon, and the Starknet Foundation launched Proof, an 8-week incubator for high-potential privacy teams. Applications close 10 July, so be quick. 2⃣ Starknet is becoming a real bet on post-quantum security StarkWare published a roadmap to make Starknet an end-to-end post-quantum-secure chain well before the Q-Day deadline: - Phase 0 (the foundation): STARK proofs already post-quantum secure, S2morrow's post-quantum wallet PoC already running on Mainnet, and Native Account Abstraction making wallet migration smooth for everyone. - Phase 1 (in progress): make new activity post-quantum secure by default. Work started, ~2 months to completion. - Phase 2 (next): give existing contracts a path to post-quantum durability, without breaking interfaces or forcing painful migrations. 1-2 months after phase 1. - Phase 3 (depending on Ethereum): the two remaining inherited surfaces, bridge messaging and blob data availability through KZG commitments, will be resolved as soon as Ethereum migrates its own stack. 3⃣ Better performance, more post-quantum security Starknet v0.14.3 goes live on Mainnet Monday, 6 July, bringing: - Keccak support for client-side proving, enabling virtual private txs signed with EVM signatures - A quantum-resistant SNOS hash, with Blake replacing Pedersen - Block times down from 2 to 1.5 seconds - A dynamic L2 gas base fee for more adaptive pricing during congestion Note: an 8-minute downtime at 8:10am UTC on Monday, and some breaking changes for builders, read the pre-release notes! 4⃣ The ecosystem keeps shipping - STRK is now listed on Robinhood - Extended launched its spot market offering, starting with BTC, ETH, and USDT, with spot and perpetuals sharing a single margin account. We also know the next 6 months' focus: decentralization, ecosystem expansion, the transition to a community-owned protocol, and a massive partnership to be announced (eToro announced yesterday). - Xverse now supports Ledger on Mobile, any user can now use the leading hardware wallet on Xverse mobile to access Starknet. - Medieval Tech became the first Starknet project accepted into the NVIDIA Inception program, with Octopi, a real-time spatial intelligence platform built in parallel of the AMMA prediction market. - Troves released a WBTC boosted vault: a one-click advanced DeFi strategy yielding ~7% - Vesu launched Explore: track positions, inspect pools, and monitor liquidations in one place. - 5 new projects launched on Mainnet this month: ArcX (Pendle-like mechanism on top of Extended) - Starkscan (explorer combining an explorer, an API surface, and an agent workflow layer) - Deadeye (Distribution Markets) - Gaffer (fantasy soccer game) - DeFa (RWA project) 5⃣ The numbers keep improving - Starknet crossed 300M transactions processed on Mainnet - STRK staking reached 1.4B STRK, ~22% of the circulating supply. - Starknet is still the #1# L2 by developer activity across the Ethereum ecosystem. - In only a few days: ArcX hit $400,000 TVL on top of Extended, Hyper xSTRK by Troves filled all its tiers, and the privacy pool reached 5k txs and 100 new users per day, with $500 in daily revenue, during the Shield rush campaign. Can’t stop, won’t stop.
