El Salvador relocates Bitcoin reserve into multiple wallets to reduce exposure to quantum attacks
The nation adopts a multi-address approach to safeguard its Bitcoin holdings from emerging quantum computing security risks.
Key Takeaways
- El Salvador is relocating its Bitcoin reserves to several new addresses.
- The move is aimed at strengthening the security of the National Strategic Bitcoin Reserve against future technological risks.
El Salvador has begun redistributing its national Bitcoin reserve across multiple fresh, unused addresses as part of a strategy to boost security and mitigate quantum-computing risks, according to an announcement from the country’s National Bitcoin Office (ONBTC).
The office said quantum computers could theoretically break public-private key cryptography using Shor’s algorithm, which affects not only Bitcoin but also banking, email, and communications systems.
“When a Bitcoin transaction is signed and broadcast, the public key becomes visible on the blockchain, potentially exposing the address to quantum attacks that could discover private keys and redirect funds before the transaction [is confirmed],” ONBTC stated.
Previously, the country reused a single address for transparency purposes, which continuously exposed public keys. The new system, managed by ONBTC, maintains transparency through a dashboard displaying the total balance across all addresses while eliminating the need for address reuse.
Following the transfer, each new wallet will hold up to 500 Bitcoin. Mononaut, the founder of Mempool, said that El Salvador had distributed the funds across 14 new addresses.

At the time of writing, El Salvador held over 6,280 BTC worth more than $680 million. The country keeps adding a Bitcoin a day to its treasury.
Talk of quantum risks has circulated in the crypto community for years, but started picking up earlier this year after Google unveiled Willow , a quantum chip it claimed could solve certain computational tasks in minutes.
The release renewed concerns about quantum computing’s progress and its potential impact on Bitcoin’s cryptographic foundations.
The main concern revolves around Bitcoin’s use of elliptic curve cryptography (ECDSA) to protect private keys.
A sufficiently advanced quantum computer running Shor’s algorithm could theoretically derive a private key from its public key, enabling attackers to forge digital signatures and steal funds, just as ONBTC mentioned in its post.
For now, experts broadly agree that current quantum computers lack the power and stability to pose an immediate threat. However, developers and researchers are exploring quantum-resistant cryptographic techniques to secure Bitcoin and other networks for a future “quantum-safe” era.

Foreign investors have made net sales of $31 billion in Indian stocks this year, and administrative controls are accelerating hedging demand towards the offshore NDF market, with the effectiveness of interventions continuously diminishing. The most critical risk lies in the fact that the yield spread between Indian and US 10-year government bonds has sharply dropped from 600 basis points in 2013 to just 200 basis points, with the traditional interest rate defense line nearly breached. India faces a dilemma: persisting on the current path will exhaust policy space, while relying on rate hikes to rebuild the yield spread would directly stifle economic growth.
