El Salvador’s Bitcoin Office has announced that the government has moved its national bitcoin holdings from a single address into multiple new, unused addresses as a security and custody upgrade for the country’s National Strategic Bitcoin Reserve. According to the announcement, this restructuring is intended to align with best practices in Bitcoin treasury management and to reduce exposure to a potential future quantum computing attack by avoiding concentration of funds in a single address whose public key could become visible and vulnerable once spent. In technical terms, the move leverages a key property of Bitcoin’s design: an unused address reveals only a hash of its public key, which is significantly harder for a future quantum computer to attack than a fully exposed public key. By spreading the reserve across many fresh addresses and capping the balance per address, El Salvador aims to minimize the damage that could occur if, in a future quantum era, any one address’s public key is revealed and compromised after spending. The decision also reflects broader concern in the Bitcoin and cryptography communities that practical quantum computers capable of breaking current public‑key schemes may arrive within years rather than decades, and that high‑value holders should adjust operational practices in advance.
