Main PageNew Bitcoin quantum proposal offers Satoshi Nakamoto a way to prove control without moving BTC. A fresh idea from the venture fund Paradigm allows keyholders to quietly mark when they own at-risk keys - well ahead of quantum machines showing up. This could open a way out should Bitcoin eventually retire outdated addresses.
MATH FUTURE TECH
Inside Bitcoin’s worries about quantum computing sits an old puzzle named Satoshi. That mystery shapes every fear people carry.
Hidden inside outdated digital vaults, millions of bitcoin might slip into wrong hands should ultra-fast quantum machines ever emerge. Sitting among them - about 1.1 million coins tied to a shadowy founder named Satoshi Nakamoto, valued near $84 billion today. Their safety rests on math that future tech could unravel.
A shift in the rules could block old-style addresses over time. That change would push users to switch before hackers crack their keys. Moving becomes necessary once protection kicks in. Safety comes from upgrading ahead of threats. The update disables outdated spending methods gradually. Users must act while there is still time.
RESET BUILT INTO CODE
Back in April, Jameson Lopp - a well-known coder - joined five peers to suggest phasing out address types at risk from quantum attacks. Their plan, filed as BIP-361, sets a five-year window for change. Funds left behind after the shift would be locked down, unable to move. The idea moves slowly, giving users time. Not every wallet adapts fast. Security grows tighter when outdated forms fade. Coins stuck in old formats lose access. Progress here means leaving some systems behind. A quiet reset built into code.
Still, that idea brought along a fresh issue. For Satoshi - and others who’ve stayed quiet for years - waking up means showing themselves or walking away empty-handed.
TIMESTAMPS
A fresh idea dropped Friday by Dan Robinson, who helps lead Paradigm, sidesteps the usual compromise using something called Provable Address-Control Timestamps - PACTs for short. Instead of accepting limits, his approach builds on timing proof tied directly to wallet control.
Ownership gets locked in time, not moved around. Proof sits quietly on a date-stamped record. Wallet holders keep things hidden till they decide to spend. Only then does any detail come out.
Out of nowhere, a holder picks a random salt - just secret bits that ensure a crypto commitment stays one-of-a-kind and unpredictable. Instead of spending funds, they lean on BIP-322, a method letting them sign messages from a Bitcoin address. That signature becomes their proof of ownership, quietly confirming control.
STARK
A mix of salt and proof gets packed into one onchain record, then stamped in time using OpenTimestamps - this part runs freely, tying information to Bitcoin's chain via grouped transactions. Hidden away, the salt, proof, and time file remain off public view.
Should Bitcoin ever activate a soft fork locking up coins at risk from quantum attacks, it might offer a way out - through a STARK proof. This kind of ZERO knowledge evidence stays safe even when faced with quantum machines. What matters is proving ownership was established earlier than the rise of such powerful hardware.
BIP 32
Proof comes first, only then does spending happen coins unlock once it's verified. Timing stays hidden, so do the numbers involved, plus whose address it really was. Here’s the thing these PACTs plug a hole left open in BIP-361, one that skips past older setups. Instead of ignoring old wallet forms, they build in a way out for those made with BIP-32, the method rolled out back in 2012. But wallets before that time, like nearly all linked to Satoshi, operate outside BIP-32 entirely. Because of that, the newer fix just doesn’t reach them.
