El Salvador Sends $678M in Bitcoin to Address Quantum Computing Risk

El Salvador recently took a significant step to enhance the security of its significant Bitcoin holdings by transferring 6,274 Bitcoin, valued at $678 million, into 14 new wallet addresses. This measure was implemented in response to the potential threat posed by advanced quantum computing attacks, as outlined in a report from Project Eleven, which highlighted the vulnerability of over 6 million Bitcoin, equating to around $650 billion, to quantum computers capable of cracking the elliptic curve cryptography (ECC) keys securing Bitcoin transactions. Despite the alarm raised by this report, Michael Saylor, known for his role in MicroStrategy’s Bitcoin strategy, downplayed the risk in June, expressing confidence that the development and hardware sectors would address any serious vulnerabilities that may arise.
The rationale behind the recent security move by El Salvador is to safeguard its digital assets from potential breaches through the distribution of funds across multiple addresses, each capable of holding up to 500 BTC. The concern lies in the fact that once Bitcoin is spent from an address, the public keys become susceptible to exploitation, potentially enabling quantum computers to decipher them as the technology progresses.
The quantum threat outlined by Project Eleven in April underscores the potential risks associated with quantum computing advancements. While the report highlighted the significant value at risk in the event of quantum attacks on Bitcoin, it also acknowledged the current limitations of quantum computing, which has yet to successfully crack a 3-bit key using Shor’s algorithm, while Bitcoin private keys are significantly more complex at 256 bits. Despite the theoretical threat posed by quantum computing, the consensus appears to be that the industry is not currently facing an imminent risk of quantum attacks on cryptocurrency.
El Salvador’s proactive security measures come at a time when the country faces scrutiny from the International Monetary Fund (IMF) over its Bitcoin initiatives. The IMF published a report in July indicating a halt in new Bitcoin purchases by El Salvador since February. Further complicating matters is a $1.4 billion funding deal struck with the IMF in December 2024, which was contingent on El Salvador scaling back its Bitcoin operations, a condition currently subject to dispute.
In a related development, Tether, the issuer of the USDT stablecoin, has adjusted its blockchain strategy following feedback from various blockchain communities. Initially planning to discontinue smart contracts on five blockchains, namely Omni Layer, Bitcoin Cash SLP, Kusama, EOS, and Algorand, Tether has revised its approach. Instead of freezing these contracts, Tether now plans to allow token transferability on these chains while discontinuing direct issuance and redemption.
While Tether’s decision affects blockchains with significant net circulation of USDT, such as Omni Layer holding $82.9 million, Tether’s dominant presence remains on Tron and Ethereum, with $80.9 billion and $72.4 billion in circulating supply, respectively. The stablecoin market as a whole reflects a growing trend, with a total market capitalization of $285.9 billion, led by USDT and USDC at $167.4 billion and $71.5 billion, respectively. Analysts foresee continued growth in the stablecoin market, potentially reaching $2 trillion by 2028, particularly bolstered by legislative support such as the recent passing of the GENIUS Act in the US, reinforcing the dollar’s global reserve currency status.
