Bitcoin in danger: Solana co-founder warns of quantum threat!
The discussion about the security of Bitcoin and the risks of quantum computing has gained urgency. Anatoly Yakovenko, co-founder of Solana, warned on the all-in Summit 2025 urgently of the potential threats for Bitcoin developers. According to crypto.news, the likelihood that quantum computers will break cryptographic defenses over the next five years.
Yakovenko emphasized that the progress in artificial intelligence shows how quickly theoretical concepts can be realized in practice. He asked the crucial question of when Bitcoin should switch to quantity -proof cryptography. In particular, quantum computers with algorithms such as Shor’s could crack the Elliptic Curve Digital Signature Algorithm (ECDSA) that protects Bitcoin wallets. This would enable attackers to falsify transactions and compromise wallets, which is an existential risk for the network.
Disagreement in the Bitcoin community
The Bitcoin community is divided with regard to the urgency of the quantum threats. Adam Back, CEO of Blockstream, is of the opinion that the technology is still far away and that it is relatively easy to make Bitcoin quantity -safe. In contrast, Peter Todd, a Bitcoin Core employee, sees no existing quantum computers at the moment; In his opinion, preliminary demonstrations did not count.
Luke Dashjr, another Bitcoin Core contributor, argues that the threats posed by quantum computing are less pressing than current problems like spam transactions and developer corruption. Upgrading Bitcoin to post-quantum cryptography would require a hard fork, a complex and controversial process that requires widespread support on the network.
Attack vectors and wallet risks
Yakovenko pointed out that bitcoins resulting in quantum mechanical vulnerability from two main striking vectors: ECDSA based on the SecP256K1 curve. It is estimated that about 25-30 % of all bitcoins (more than 4 million BTC) are stored in addresses with exposed public keys, which makes them susceptible to quantum attacks. Legacy pay-to-public key addresses are particularly at risk because their public keys are visible in the blockchain.
In addition, transaction windows increase the risks for users during the 10-minute confirmation time, since the public keys are exposed during this time. Yakovenko suggests that the time for upgrading bitcoins has come as soon as large tech companies use quantity-proof cryptographic stacks.
