Odaily News: Researchers from institutions including the Ethereum Foundation, Theta Labs, and StarkWare have jointly published a paper, using AI coding agents to deeply optimize the core operations of Shor's algorithm. The computing resources required for a potential quantum attack on Bitcoin and Ethereum (secp256k1 cryptographic system) have been reduced by more than 50% compared to Google's benchmark in March of this year. The number of logical qubits required for the circuit has been compressed to 1,151, and later versions have even been reduced to 813. Although current quantum hardware still cannot directly break public chains, the research shows that pure algorithmic optimization is significantly narrowing the time window for the quantum threat. The researchers emphasize that quantum-resistant upgrades take a long time and cannot be applied retroactively, and the industry needs to prepare defenses in advance. (Coindesk)

Odaily Planet Daily News: Blockchain technology company Starkware stated that on August 26, a transaction using researcher Avihu Levy's Quantum-Safe Bitcoin (QSB) scheme was mined on the Bitcoin mainnet, without requiring a soft fork, hard fork, or modification of consensus rules.The transaction consumed 10,000 sats and was processed through MARA Foundation's Slipstream service, as the non-standard format typically cannot propagate through Bitcoin's public mempool. The test consumed several hours of GPU computation, costing approximately $150 to $200.QSB employs hash-based quantum-resistant spending conditions and reduces quantum attack risks through signature trial mining, but still requires users to proactively migrate funds and cannot protect assets whose public keys have already been exposed. Starkware CEO Eli Ben-Sasson still supports introducing a protocol-level solution via a soft fork. (Bitcoin.com News)

Odaily News: Avihu Levy of StarkWare used signature grinding techniques to protect public key data while ensuring transactions remain secure in the Bitcoin mempool, providing a second layer of security for assets.

Odaily News: Starknet announced the completion of a quantum-resistant signature transfer test. A wallet account using quantum-resistant signature mechanisms completed a real transfer on the Starknet mainnet, with transaction fees of approximately 6 US cents, and the transaction can be queried via a block explorer. This account is currently an experimental, unaudited version intended primarily for research and testing.StarkWare stated that this transfer was made possible by Starknet's account model design. Unlike most blockchains that fix the signature algorithm at the protocol layer, each Starknet account is a smart contract that can autonomously define which signature schemes it accepts. As a result, users can upgrade their wallets from traditional elliptic curve signatures to quantum-resistant signatures without a hard fork, without migrating assets, and without changing their addresses.StarkWare pointed out that most blockchains face quantum computing risks because both wallet signatures and the underlying verification systems rely on elliptic curve cryptography. Once large-scale quantum computers emerge, running Shor's algorithm could break the associated cryptographic systems. Currently, the Starknet ecosystem already supports a quantum-resistant signature scheme based on Falcon-512, which is part of the NIST post-quantum cryptography standardization framework. The relevant implementation has been advanced by ecosystem teams and organizations such as OpenZeppelin.

Odaily reports that StarkWare CEO Eli Ben-Sasson has proposed replacing Bitcoin's 21 million hard cap with a 4% annual issuance rate. He argues that the current hard cap is "unreasonable" because private keys are lost over time, stating, "As time approaches infinity, all private keys will be lost." Ledger estimates that approximately 4 million Bitcoins have already been permanently lost. Ben-Sasson stated that a 4% annual issuance rate roughly aligns with the global population growth rate. This proposal has sparked opposition from the community, with critics arguing that the fixed cap is a core value of Bitcoin, and that Bitcoin is divisible into 2.1 quadrillion satoshi units, which is sufficient to address the decline in available supply.

Founded by former Revolut employees, Extended opened for trading at the end of 2024. (financefeeds)

Odaily reported that zero-knowledge scaling company StarkWare has released a Starknet quantum resistance roadmap, stating that the roadmap is divided into three phases to address the risk of future quantum computing attacks. StarkWare CEO Eli Ben-Sasson stated that Starknet can leverage its architectural advantages to achieve quantum resistance, as its underlying cryptography is based on zero-knowledge STARK proofs. According to reports, the first phase of the roadmap includes replacing part of the existing secure mathematical mechanism, Pedersen hash, with a quantum-resistant version, and adding quantum-resistant signatures; the second phase focuses on migration tools, upgrading existing smart contracts without requiring developers to manually rebuild applications; the third phase involves dependencies that Starknet cannot solve alone, primarily relying on Ethereum's quantum upgrade roadmap. Circle, Ethereum, Solana, Tezos, and Algorand have all proposed quantum resistance roadmaps. (Cointelegraph)

Odaily Odaily reports that StarkWare announced on the X platform that Starknet v0.14.3 will go live on mainnet this month. The testnet launch is scheduled for June 9, and the mainnet launch is scheduled for June 22. The new version will support dynamic adjustment of L2 Gas base fees based on STRK, increase block generation speed, reduce the target L2 Gas consumption per block while keeping the maximum block size unchanged, and deprecate RPC 0.8. As this update contains significant changes, the official team recommends all developers carefully read the pre-release notes to prepare for compatibility and upgrades.

Odaily Planet Daily reported that Starknet, the Ethereum Layer 2 network developed by StarkWare, has officially launched strkBTC. This is a new Bitcoin-based asset designed to achieve private balances and anonymous transfers through zero-knowledge proof (ZK) technology while maintaining composability with DeFi applications. After its launch, strkBTC supports "re-anonymization," allowing assets to be bridged back to entirely new, unlinked Bitcoin addresses, and also provides compliance audit and asset screening features.

Odaily News Researcher Avihu Levy has proposed the Quantum Safe Bitcoin (QSB) scheme, which enables Bitcoin transactions to be quantum-resistant using only existing traditional script constraints. According to the scheme, standard Bitcoin transactions rely on ECDSA (Elliptic Curve Digital Signature Algorithm) signatures, which could be broken by a sufficiently powerful quantum computer running Shor's algorithm. To address this issue, the researchers proposed QSB, which replaces the reliance on elliptic curve cryptography for transaction security with a Binohash-based construction that uses a one-time signature scheme embedded within Bitcoin scripts.Binohash achieves transaction integrity through a proof-of-work puzzle based on signature length. However, the paper notes that quantum computing could also crack this puzzle.QSB eliminates this vulnerability by creating a "hash-to-signature" puzzle that requires the payer to solve a puzzle based purely on hashing rather than elliptic curve mathematics, thereby making it resistant to quantum attacks that break elliptic curve cryptography."Since this puzzle depends only on the preimage resistance of RIPEMD-160 (and not on any elliptic curve assumption), it is completely unaffected by Shor's algorithm," the researchers explained.
