Will Quantum Computing become the ultimate killer of Bitcoin? This question has recently been brought back to the forefront.

James Check from the blockchain analysis platform Checkonchain offers an interesting perspective: this issue is probably not something that can be resolved by technology; the key lies in whether the community can reach a consensus. His concerns are quite practical—those users who store coins with old addresses may see years of dormant Bitcoins suddenly flood the market if quantum computers successfully crack them. The data is quite alarming: more than one third of Bitcoins ( 32.4% ) have not moved in five years, and nearly 20% ( 16.8% ) have been lying dormant for over ten years.

Ceteris Paribus, a researcher at Delphi Digital, holds a similar view. He believes that the uniqueness of Bitcoin facing the quantum threat lies precisely in the fact that technology is a secondary contradiction. What is more tricky? Blockstream CEO Adam Back puts it bluntly: the community must choose between two options - either forcibly abandon old addresses or watch funds get stolen.

Although the National Institute of Standards and Technology in the United States has endorsed several quantum-resistant encryption schemes, the old P2PK format addresses of Bitcoin are still exposed. In contrast, new chains like Sui and Solana have already begun deploying quantum protection. What about Bitcoin and Ethereum? Still on the way.
