- Willy Woo recommends transferring Bitcoin to an unspent SegWit handle (bc1q) to cover the general public key from future quantum threats.
- The chance is that quantum computer systems might use uncovered public keys to derive personal keys, and Taproot addresses (bc1p) expose this key.
- Some customers argued that is an impractical, momentary repair that requires the cash to stay untouched till the Bitcoin community absolutely upgrades.
Bitcoin analyst Willy Woo is telling his followers they will decrease future quantum-computing risk, principally by transferring cash right into a SegWit handle and… effectively, go away them there till the community adopts quantum-safe cryptography.
Woo said that the present-day taproot addresses (the prefix that begins with bc1p) will not be protected as they embed the general public key into that handle. “Not good,” he added.
As an alternative, customers ought to create a brand new SegWit pockets with “bc1q”, and never bc1p. As soon as accomplished, simply ship all of your cash there and wait to see if the Bitcoin community upgrades to a quantum-safe protocol, Woo claimed.

Huge Scary Quantum Computer systems, or BSQC
His level is that highly effective quantum machines might sooner or later derive personal keys from uncovered public keys. Taproot outputs can reveal a public key up entrance, whereas traditional SegWit retains the general public key hidden behind a hash till the cash are spent.
Prior to now it was about defending your PRIVATE KEY (your seed phrase). Within the age of massive scary quantum computer systems (BSQC) which might be coming, you want to defend your PUBLIC KEY additionally. Principally a BSQC can work out your personal key from a public key.
Woo, nevertheless, famous that is only a momentary resolution and never a repair. And it’s fairly impractical as holders wouldn’t (or shouldn’t) spend or transfer their cash from the SegWit handle as a result of doing so reveals the general public key on-chain, defeating the aim.
He added that enormous custodians, like ETFs, company treasuries, and chilly storage, can enhance safeguards earlier than a protocol improve arrives in the event that they regulate their operational setups.
On timing, Woo referenced the prevailing view that sensible quantum threats are unlikely earlier than 2030 and famous that quantum-resistant requirements are already advancing.
So, When Do We Begin Panicking?
Not everybody agreed with Woo. Charles Edwards, founding father of Capriole, argued the method is insufficient and that Bitcoin wants a network-level improve as quickly as attainable. He warned that suggesting a seven-year window dangers complacency.
SegWit (Segregated Witness) is a BTC protocol that modified how knowledge is structured and saved by separating transaction signatures from transaction knowledge, making transactions simpler and sooner to course of.
However SegWit addresses simply present a brief benefit towards quantum assaults. Principally, the primary menace from quantum computing is that such a tool is sufficiently highly effective to make use of Shor’s algorithm to interrupt Bitcoin’s ECDSA, its present cryptographic signature.
Nonetheless, Quantum computing isn’t considered a menace but as a result of there aren’t sufficient qubits and, most significantly, such computer systems don’t have the soundness to keep up their quantum state persistently over time with out being disrupted by errors. That’s as a result of qubits are extraordinarily delicate and delicate to any change of their surroundings.
