I separate quantum fact from crypto fiction.

[Dr. Q. Bits (PhD) @drQbits]

We’ve entered the Quantum Risk Window: the time to upgrade Trillion dollar blockchains now overlaps with the possibility of a Cryptographically Relevant Quantum Computer (CRQC).

Published March 9, 2026: GRI/evolutionQ surveyed 26 quantum experts, this is the gold standard of Quantum timeline estimations.

13/26 respondents see 50%+ odds of a CRQC in 5-10 years.

Satoshi has long cited quantum computing as the only true existential threat to Bitcoin – it's now real. The same threat applies to all major blockchains. They all have a meaningful percentage of supply with exposed public keys.

Given a public key, a CRQC can find the private key and access funds in the wallet. This is the lowest hanging fruit for an immediate return on a CRQC and can zero the value of a network's native token.

There is no clean solution to this problem, nodes either have to burn vulnerable supply or let a quantum computer take it.

This topic will inevitably soon be debated more than the block size war in 2017.

@punk9059 Counterpoint: no real store of value can have a real existential threat

[Dr. Q. Bits (PhD) @drQbits]

What do you think about the inactive coin problem? Even if the Bitcoin community creates a viable plan before we overlap with the possibility of a CRQC, there will still be hundreds of billions (10%+) of Bitcoin supply that will not upgrade. Likely leads to a debate/fork more controversial than the block size wars. I think the drag on price is going to be much worse than most realize.

[Dr. Q. Bits (PhD) @drQbits]

No amount of quantum upgrades to signatures can fix the inactive quantum vulnerable coins which represent up to 25% of supply on major coins, including ZEC. The philosophical question of to do with these coins breaks the neutrality of the chains.

Arguably more concerning than Google reducing the number of qbits required to break ECC is the response from Bitcoin core devs.

Google's findings materially advance the Quantum timeline and narrow the window for Bitcoin to upgrade it's infrastructure/create a plan for dead coins.

It's more concerning the entire paper is focused on crypto. How do we know Google hasn't already broken ECC or that a Chinese competitor (who are often much more secretive) hasn't?

No SOV can have an existential threat, let alone one that could be real in 2-3 years.

We haven’t even started talking about the non-technical problems caused by quantum computing.

The philosophical problem is the most controversial, as there is no true solution.

[Dr. Q. Bits (PhD) @drQbits]

While I tend to agree, quantum is the first and only existential threat to Bitcoin. Difficult reality for a SOV.

While most UTXO's will be in PQ infrastructure by the time it happens, there is also a large non-technical problem.

The key philosophical challenge of whether vulnerable coins should be rendered unspendable or allowed to remain retrievable by quantum attackers is likely to cause a debate bigger than the block size wars.

Ultimately there is no perfect solution for these coins.

Quantum concern on Bitcoin is a psyop.

[Dr. Q. Bits (PhD) @drQbits]

What decision do you think the Bitcoin core devs come to regarding whether vulnerable coins should be rendered unspendable or allowed to remain retrievable by quantum attackers?

What is the game theory once a CRQC has cracked one of Satoshi's wallets? Will they wait until they've cracked multiple/all wallets before moving anything?

Assuming multiple entities are doing this would the tx be RBF'd until the prize is near zero?

How would the attacker(s) also calculate these decisions against the probability of Bitcoin significantly declining in value the second a UTXO from a Satoshi wallet is moved?

Is a quantum computer taking vulnerable coins a crime?

[Dr. Q. Bits (PhD) @drQbits]

[Dr. Q. Bits (PhD) @drQbits]

@nic_carter Timelines to a CRQC are only moving in one direction, while the Bitcoin community isn't moving at all

[Dr. Q. Bits (PhD) @drQbits]

Take the tin foil hat off for AI and put it on for quantum.

This looks like a password bruteforce instead of a private key being derived.

The bigger unlock vector is quantum once public keys are exposed. Then dormant BTC stops being a curiosity and becomes a governance crisis, because Bitcoin has no clean answer to whether vulnerable coins should be burned, frozen, or left to whoever gets there first.
