Summary

El Salvador’s National Bitcoin Office redistributed 6,286 BTC, worth over $682 million, from a single address into multiple unused addresses to enhance security. This move responds to the potential risks posed by quantum computing, which could expose Bitcoin to attacks if public keys are revealed. The country now limits holdings to 500 BTC per address and provides a public dashboard for transparency. While the IMF's July review revealed no new Bitcoin purchases, the government continues to buy one BTC per day as per President Nayib Bukele's 2022 commitment.

Terms & Concepts
  • Shor’s algorithm: A quantum algorithm that can break common public–private key cryptography, raising concerns for Bitcoin signatures if public keys are exposed before confirmations.
  • Public–private key cryptography: A system using linked keys for signing and verification; in Bitcoin, spending reveals the public key on-chain, which the Bitcoin Office warned could be targeted by quantum attacks pre-confirmation.
  • Address reuse: Using the same Bitcoin address repeatedly. Avoided for security and privacy; El Salvador is distributing funds to multiple unused addresses to limit exposure.
