What do you think, what key length will these white hats be able to crack?
How many people have access to quantum computers? I would expect the budget involved for the ones who have to far exceed 1 BTC, which makes me think this small prize isn't worth their effort.
Exactly, the cost of owning a quantum computer is from $10M+. If you want to rent quality time using one from any cloud providers this is what it will cost you;
| Provider | | | Cost per Hour (est.) | | | Keep in mind | | |
| IBM Quantum | | | $1,500–$10,000/hr | | | Via IBM Premium Plan | | |
| Quantinuum | | | $5,000–$20,000/hr | | | High fidelity, access to H1 system | | |
| IonQ | | | $3,000–$15,000/hr | | | Available via Amazon Braket | | |
| AWS Braket | | | Pay-as-you-go | | | For multiple providers | | |
Since this is a team based effort contest, only individuals with the required technical requirement will join together to form a team.
