News linked to both this project and an event.
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.
