Glassnode Finds 20% of Bitcoin Quantum-Exposed by Behavior, Not Code
Glassnode information reveals 4.12 million Bitcoin (BTC) are held in quantum-exposed addresses on account of tackle reuse, partial spending, and custody practices, greater than double the 1.92 million BTC uncovered by Bitcoin’s older script varieties.
The on-chain agency splits Bitcoin’s quantum-exposed provide into structural danger stemming from the protocol’s design and the publicity of public keys, and operational danger arising from how holders handle their addresses and outputs.
Why Structural and Operational Exposure Are Not the Same
Structural publicity covers outputs the place the general public key seems on-chain by default. The bucket contains early Pay-to-Public-Key (P2PK) coins from the Satoshi period, naked multisig, and trendy Pay-to-Taproot (P2TR) outputs.
Operational publicity works in a different way. Address varieties like Pay-to-Public-Key-Hash (P2PKH) and Pay-to-Witness-Public-Key-Hash (P2WPKH) conceal public keys behind hashes at relaxation. However, as soon as a holder reuses an tackle or partially spends from it, that safety not applies to any remaining stability.
Glassnode places the 2 buckets at 30.2% of all issued Bitcoin mixed. Together, they present that the operational share is 2.1 instances bigger than the structural share.
“The principal perception is that the majority present at-rest publicity isn’t merely a legacy script-design drawback – it’s a key- and address-management drawback,” the agency mentioned.

The report revealed that exchanges kind the biggest identifiable subset of operationally uncovered BTC. They maintain about 1.66 million BTC, roughly 40% of the pool.
“It additionally seems high in relative phrases: roughly half of labeled exchange-held BTC falls into the prone bucket, in contrast with lower than 30% of non-exchange provide,” Glassnode mentioned.
Exposure varies sharply between custodians. Glassnode marks Coinbase balances at 5% uncovered. Meanwhile, Binance sits close to 85% and Bitfinex at 100%.
Other Bitcoin holding entities additionally diverge. WisdomTree seems absolutely uncovered. Grayscale holds about half its provide in uncovered outputs. However, sovereign wallets within the US, UK, and El Salvador show zero exposure.
Glassnode notes exchange-held BTC has drifted from roughly 55% operationally protected in 2018 to about 45% at present.
Bitcoin Improvement Proposal 360 (BIP-360) would harden Taproot. However, a lot of the operational bucket can shrink at present by tackle rotation and prevented reuse, with none consensus change.
