Google has published research suggesting that a sufficiently powerful quantum computer could crack Bitcoin's core cryptography in under nine minutes, one minute faster than the average Bitcoin block settlement time, potentially threatening the world's largest blockchain. The research also suggests that around 6.5 million bitcoin tokens, worth hundreds of billions of dollars, sit in addresses that could be directly targeted by a quantum computer. The potential compromise would damage Bitcoin’s core tenets, including trust the code and sound money. Developers are already considering a series of upgrades to prevent this threat. The Bitcoin Improvement Proposal (IP) 360 removes the public key from the Bitcoin chain and introduces a new output type called Pay-to-Merkle-Root (P2MR). However, if implemented, this would only protect new coins and 1.7 million BTC currently sits in old P2PK addresses, including Satoshi's coins. Other proposals propose to reduce post-quantum security on kilobytes (KB) and increase block transaction fees.
