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.
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 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.

According to The Block, Avihu Levy, a researcher at StarkWare, published a paper proposing the Quantum Safe Bitcoin (QSB) scheme, claiming it enables quantum-resistant transactions under Bitcoin’s existing script rules—without requiring a soft fork. This scheme replaces elliptic-curve cryptography with the RIPEMD-160 hash function via a “hash-to-signature” puzzle, thereby enhancing resilience against quantum attacks. The paper notes that QSB’s current per-transaction cost ranges from $75 to $150—significantly higher than today’s average transaction fee—and involves complex user experience; thus, it is recommended only as a “last resort.” The scheme remains constrained by script opcodes and size limits, and does not yet support all use cases—such as the Lightning Network. Compared to BIP-360—which requires protocol-level changes—QSB needs no modifications to the Bitcoin protocol, but remains experimental.
