El Salvador Splits Its National Bitcoin Reserve Across Multiple Addresses
El Salvador announced that it would move its national Bitcoin reserve from a single address into multiple addresses holding no more than 500 BTC each. The restructuring preserved public visibility while reducing concentration risk and was explicitly framed in part as preparation for possible future quantum-computing threats.
On August 29, 2025, El Salvador’s National Bitcoin Office announced a restructuring of the country’s sovereign Bitcoin custody. Instead of keeping the reserve concentrated in a single publicly tracked address, the government would distribute the holdings among multiple new addresses, with each address holding no more than 500 BTC.
The government said the change was intended to strengthen long-term security while preserving transparency through a public dashboard. Splitting the reserve limited the amount exposed through any one address or key-management failure. Officials also connected the move to discussion of future quantum-computing risk, particularly the theoretical danger that sufficiently capable quantum systems could derive private keys from exposed public keys.
The quantum threat was prospective rather than an indication that Bitcoin’s cryptography had already been broken. The immediate historical event was operational: a national government managing a large Bitcoin reserve changed its custody architecture in response to evolving security assumptions. That made the episode different from another sovereign purchase or price disclosure.
El Salvador had already occupied a unique place in Bitcoin history through its legal-tender experiment and continuing government holdings. The August restructuring added a new dimension to that story—sovereign key management. It showed that once a state holds Bitcoin at scale, questions familiar to exchanges and individual holders, such as address exposure, concentration and long-term cryptographic security, become matters of national reserve administration.
