Researchers Claim to Have Cracked Bitcoin Encryption with Quantum Computing

The threat of quantum computers to the crypto industry has reached a new level after an independent researcher named Giancarlo Lelli claimed to have hacked Bitcoin's security protocol in just 45 minutes. Through a hacking competition with a prize of 1 Bitcoin, the researcher successfully broke the 15-bit Elliptic Curve Cryptography (ECC) algorithm using a public quantum computer. This achievement proves that the public key, which serves as the wallet address identity, is now increasingly vulnerable to future attacks that could threaten digital assets worth $2.5 trillion.
​The method used is an extension of Shor's Algorithm, a mathematical procedure designed to break public key encryption very quickly through quantum computation. Recent studies show that the efficiency of this attack has increased dramatically; the number of qubits needed to fully crack Bitcoin encryption has dropped by up to 1,300 times compared to estimates in 2022. This situation raises significant concerns in institutional markets, with even BlackRock warning their ETF investors about the risk of total loss due to this technology.
​The greatest risk currently looms over approximately 6.9 million BTC whose public keys have already been exposed on-chain, including Satoshi Nakamoto's 1.1 million BTC holdings. Without a mass migration to Post-Quantum Cryptography (PQC) standards, these old assets are threatened by the "Harvest Now, Decrypt Later" strategy. In this scheme, malicious actors begin collecting transaction data today to be forcibly decrypted once quantum hardware reaches a commercial scale in the coming years.
