El Salvador moved his national Bitcoin hiding place in several wallets on Friday on the cover against a future cryptographic threat, according to official publications and the blockchain registers.
The country has transferred 6,274 BTC – approximately $ 678 million at current prices – on a single address and in 14 separate addresses, each new address holding up to 500 BTC.
Divided portfolios to limit exposure
Based on Bitcoin Office reports, this decision was aimed at reducing the impact of any quantum breakthrough.
The officials said that a quarter of work was a simple defensive step. Once the funds have been spent from a Bitcoin address, the public key of the address becomes visible on the blockchain.
This public key, warns people, would be the target if quantum machines reached the ability to resolve the cryptography of the elliptical curve.
El Salvador moves funds from a single Bitcoin address in several new unused addresses as part of a strategic initiative to improve security and long -term guard of the Bitcoin Nationale strategic reserve. This action aligns with best practices in Bitcoin …

According to Project Eleven, 6 million Bitcoin – worth around 650 billion dollars – could be exposed if such a capacity had arrived.
The calculation behind the concern is clear: the private keys Bitcoin use 256 -bit values, and the current quantum systems performing the algorithm of Shor have not even cracked a three -bit key.
Quantum risk is largely theoretical
Experts say that practical quantum attacks against Bitcoin are not imminent. The eleven project and other researchers emphasize that the threat remains theoretical for the moment.
No public quantum computer has demonstrated the power necessary to threaten modern cryptography.

Michael Saylor said in June that the warnings concerning quantum attacks are exaggerated and that if a real threat appeared, the upgrades of Bitcoin software and the hardware ecosystem would be implemented.
The argument follows a simple logic: software and hardware can be modified; Cryptography can be improved. This does not make the risk zero. It only puts the danger away in the chronology of most observers.
The technical point that stimulates this action is simple. When the pieces leave an address, the blockchain reveals the public key connected to the private key used to sign this transaction.
If a sufficiently powerful quantum computer appears later, this public key could, in theory, be used to derive the private key and drain the address.
By dividing the funds over 14 addresses, El Salvador reduces the maximum quantity exposed if only one portfolio is compromised after the expenses.

What it means for other holders
Guardians and large holders can note stages at low cost. This decision is low in operational cost but great in symbolism.
Other governments, exchanges and major holders continue to look at the progress of cryptography; The division of large titles is a simple technique that they can use without changing the operation of Bitcoin itself.
