How Do We Protect Bitcoin From Quantum Computers? Not With A Joke

Just lately, Undertaking Eleven (a quantum computing analysis group) introduced a 1 bitcoin reward for the primary workforce capable of full a problem to display breaking a ECC (elliptic curve cryptograph) key utilizing Shor’s algorithm on a quantum laptop. 

The deadline for this problem is April fifth, 2026, which means so as to qualify for the prize a workforce should display breaking a key pair it have to be completed earlier than that deadline. 

That is frankly a totally absurd and meaningless prize for quite a lot of causes, the primary of which is the deadline of just below a 12 months from at the moment. Even extremely optimistic projections in regards to the progress of quantum computing put the timeline of virtually attaining such a purpose at extra like 5-10 years. Anticipating a workable proof of idea demonstration that really breaks a keypair in a single 12 months is fairly laughable at face worth, even in case you do view quantum computing as a cloth menace within the brief time period. 

Subsequent is the issue of financial incentives. A single bitcoin is presently value roughly $80,000. That’s frankly not some huge cash within the grand scheme of issues. Particularly with regards to the applying of a innovative know-how like quantum computing that may carry out a whole class of computation exponentially sooner than a classical laptop. Think about how rather more beneficial issues might be completed with a working quantum laptop. 

You could possibly listen in on web connections no matter TLS, breaking safe connections to banks, fairness brokerages, personal company networks not utilizing post-quantum cryptography. You could possibly break each personal messenger utility on the planet, you might decrypt any PGP encrypted message despatched over e mail that you just knew the general public key for. You could possibly break the whole DNS system’s certificates authority hierarchy, permitting you to impersonate any server on this planet a person tries to connect with. 

All of these items have immeasurable worth past only a mere $84,000. Why on Earth would somebody with a working quantum laptop publicly reveal that reality to say a single bitcoin after they may benefit from all these different issues they might be able to doing?

Okay, let’s sweep all of these prospects apart and faux the whole world magically migrates to post-quantum cryptography apart from Bitcoin. It nonetheless is mindless to attempt to publicly declare this prize you probably have a purposeful quantum laptop. 

Let’s assume you could have a barely performant sufficient quantum laptop, that it takes an honest period of time to crack a single key. What number of naked public keys are there securing 50 BTC outputs from the primary mining epoch? THOUSANDS of them. Why on Earth would you crack one, after which go inform everybody publicly to say a single bitcoin? You’d simply attempt to crack as a lot of these early coinbase rewards as potential earlier than folks detected you. 

Lastly, the timetable by itself is simply absurd. Quantum computer systems presently are usually not even able to factoring prime numbers that individuals can do themselves of their heads mentally. In a single 12 months the know-how goes to leap from that to cracking Bitcoin keys? That’s absurd. 

So what the hell is the purpose of this prize besides some publicity stunt? It’s completely meaningless as a severe bounty to perform as a canary within the coalmine for us, irrespective of how involved or unconcerned you’re with the timeframes of quantum computer systems as a menace. 

This bounty is a joke.
