“Any attempt to freeze assets would trade off quantum-related risks for establishing a precedent regarding property rights and neutrality,” he commented.
The discussion around this topic has been extensive. Binance CEO Changpeng Zhao proposed freezing Satoshi’s estimated 1.1 million bitcoins if these coins remain inactive amid the advancement of quantum technology. Bitcoin developer Jameson Lopp has also suggested measures for restricting access to at-risk coins to thwart potential theft. However, opponents argue that freezing any individual’s bitcoin contradicts the fundamental principle that these assets cannot be seized.
To enhance bitcoin’s resistance to quantum threats, it would be necessary to change the digital signatures that validate transactions. This transition requires consensus among developers, miners, exchanges, wallet providers, and users.
“There’s no reliable figure for the costs involved, and anyone providing one is merely speculating,” Bennett noted regarding expenses. “The true challenge lies not in the cryptography itself, but in the coordination among wallets, exchanges, custodians, and protocol developers.”
Switching to new signatures may also increase the blockchain’s storage requirements, possibly leading to higher transaction fees or a decrease in the volume of transactions that can be processed. Researchers are already exploring solutions to mitigate this impact.
The Quantum Alliance, which includes members like Hacken, Charles Hoskinson’s Midnight Foundation, Quantus, and Postquant Labs, is set to release standardized security assessments and recommendations for transitioning existing networks to quantum-resistant infrastructures.
Carback also suggested establishing a trust for vulnerable coins, allowing verified owners to reclaim their assets. For bitcoin holders, the pressing concern remains whether the network can safeguard their investments without altering the very elements that make this leading cryptocurrency so attractive.
