An interesting twist in the story of quantum computers and blockchain. This week, the entire crypto world has been discussing a Google article about how quantum machines could potentially break Биткойна cryptography. But at the same time, Postquant Labs is doing something entirely different — they aren’t afraid of quantum computing; they’re trying to use it.

The company has just launched the world’s first public testnet, where a quantum computer, a GPU, and regular processors work together on a single network. The idea is simple, but bold: maybe quantum computing isn’t a threat to блокчейном, but a tool to improve it?

The testnet has already attracted 13,000 registrations from researchers from MIT, Стэнфорда, and other top universities. Of those, six teams have already launched serious computational tasks. They’re working with D-Wave’s Advantage2 system through the Leap cloud service — specialized hardware for optimization tasks, not a universal quantum computer from science-fiction films.

What’s interesting: in internal tests, the D-Wave system allegedly outperformed 80 H100 graphics processors and 480 CPU cores in solution quality, speed, and energy efficiency. It sounds impressive, but the data hasn’t been confirmed by independent sources — it’s still only the company’s statements.

Postquant Labs’ goal is ambitious: if a quantum computer really can solve optimization problems faster, with less energy consumption, and with better quality, then distributed ledgers could become useful not only for cryptocurrency trading, but also for real business applications — logistics, manufacturing, route planning.

Testnet participants can earn QUIP tokens by solving complex tasks using quantum or classical processors. QUIP is designed as a utility token for exchanging for computing resources.

But will it really work? That’s still a big question. The testnet is an experimental environment, not a finished product. Launching the main network depends on whether researchers can prove real quantum advantage and confirm market demand. Post-quantum computing in blockchain for now remains a hypothesis, but Postquant Labs is clearly ready to test it.
