Satoshi\'s 16-year-old quantum plan forms backbone of Bitcoin BIP-360 and BIP-361

Bitcoin discussions on responding to quantum computers are elevating a design proposed 16 years ago by Satoshi Nakamoto into the basis for formal proposals, including BIP-360 and BIP-361. Developers are testing a method to force cryptographic changes by setting a cutoff at a specific block height. The plan targets exposed ECDSA public keys, but could raise fees by increasing transaction data size and would permanently isolate lost early coins that cannot be migrated.

Stellar pursues quantum-resistant migration without address changes, signing key replacement central

The Stellar Development Foundation unveiled QPP, a roadmap to prepare the Stellar (XLM) network for quantum computers, and said it aims to complete a shift of all accounts to quantum-resistant signatures by the end of 2027. The plan is designed to keep existing addresses and transaction histories intact while replacing only signing keys. It outlines a three-stage rollout from 2026, adds NIST-standardised ML-DSA support, and raises dormant-account handling as a remaining issue.

Quantum computers still not a practical threat to AES-128 symmetric encryption

Even if quantum computing advances, symmetric-key encryption such as AES-128 is not a realistic target for attacks, a claim said. Cryptography engineer Filippo Valsorda, who maintains the Go programming language’s cryptography standard library, said quantum threats should distinguish between public-key and symmetric-key cryptography. He said Shor’s algorithm threatens asymmetric systems such as RSA and ECDSA, while Grover-based attacks on AES-128 remain extremely costly. He also urged focusing resources on replacing Shor-vulnerable public-key cryptography.
