Stellar Development Foundation unveils three-step roadmap for XLM quantum threat

The migration plan targets end-2027 readiness by letting accounts swap signing keys without changing addresses or transaction history, with rollout starting in 2026 and Ed25519 retirement possible after 2028.

Fact Check
The official Stellar blog post 'Introducing the Quantum Preparedness Plan' confirms every element of the claim: a three-stage roadmap, end-2027 readiness for accounts to add quantum-safe signers, key rotation via set_options without changing addresses or transaction history, rollout beginning in 2026 (Stage 1), and Ed25519 deprecation in Stage 3 with timing determined later (the CoinPost article specifies post-2028). The CoinPost and CryptoBriefing reports corroborate these details. The claim's phrasing ('after 2028') aligns with the official Stage 3 'TBD' deprecation and CoinPost's '2028以降' framing.

Summary

Stellar Development Foundation has outlined a Quantum Preparedness Plan to prepare the XLM network for risks posed by future quantum computing advances. The roadmap is designed to let all accounts migrate only their signing keys while preserving existing addresses and transaction history by the end of 2027, with a three-phase rollout beginning in 2026. The foundation also said possible retirement of Ed25519 is being considered after 2028, signaling a phased cryptographic transition intended to strengthen long-term network resilience without forcing a broader overhaul of account identities or historical records.

Terms & Concepts
  • signing keys: Cryptographic keys used to authorize transactions and prove account control.
  • Ed25519: A digital signature scheme widely used to secure account authentication and transaction signing.
  • quantum computing: Advanced computing technology that could eventually weaken some current cryptographic methods.
