Nearly 10% of Bitcoin supply is ‘structurally unsafe’ from quantum breakthrough: Glassnode
Analytics provider Glassnode identified 10% of Bitcoin supply as structurally exposed to a quantum breakthrough, underscoring the need for a quantum-proof implementation such as BIP-360.
Nearly 10% of the total Bitcoin supply is considered “structurally unsafe” due to a quantum computing breakthrough, as their output type reveals the public key by design, regardless of address management practices, according to data analytics platform Glassnode.
Totaling about 1.92 million Bitcoin (BTC), the group includes BTC from early Satoshi-era Pay-to-Public-Key (P2PK) outputs, legacy multi-sig structures such as Pay-to-Multisig (P2MS) and modern Pay-to-Taproot (P2TR) outputs, which reveal the public key or public key-equivalent by design, wrote Glassnode in a Wednesday X post.
Bitcoin creator Satoshi Nakamoto’s coins represent about 1.1 million or 5.5% of the vulnerable supply, following another 620,000 Satoshi-era coins or 3.1% of the supply and about 200,000 coins or 1% of the supply in Taproot addresses.
