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.

Coinbase urges urgent quantum-resistant shift, warning 7 million bitcoin could be at risk

Major blockchains such as Bitcoin and Ethereum should immediately begin preparations to migrate to quantum-resistant systems, a Coinbase advisory group warned in a new report. The group said handling coins not moved to quantum-resistant addresses is the key issue, estimating about 7 million bitcoin could be vulnerable in the future. It outlined options including freezing or burning coins after a deadline, user choice, and compromise measures, while noting concerns about forced burns and property rights.

Stellar launches quantum security plan to upgrade all accounts by end-2027

Stellar developers unveiled a three-step roadmap to shift to quantum-resistant cryptography to counter threats from quantum computers. The plan starts in 2026 with changes for corporate wallets and institutions, then a 2027 protocol upgrade enabling all accounts to add quantum-resistant signers while keeping existing addresses. A final phase will retire the current cryptography, with timing to be decided later. The foundation flagged dormant accounts as a key challenge.
