Key takeaways
- Hazync verified Bitcoin blocks 1 through 1,789 in just 27 milliseconds.
- Proving the complete Bitcoin history requires roughly 17 GPU years of processing.
- The project's full-chain proving campaign is still underway.
A developer at Hazync just verified Bitcoin blocks 1 through 1,789 in a swift 27 milliseconds. Expanding that speed across the rest of the blockchain, though, demands a staggering heap of raw processing power.
Proving Bitcoin's full transaction history takes roughly 17 GPU years of compute time. Because of those steep hardware requirements, the full-chain effort isn't finished yet.
The Cost of Instant Proofs
Knocking out early blocks shows that millisecond-level validation works with advanced cryptographic proofs. But math isn't cheap. A single GPU running non-stop needs 17 years to crunch those calculations. Splitting the job across big clusters cuts down real-world calendar time, but the underlying compute cost stays massive.
Why it matters
Instant block validation could change how Bitcoin nodes operate. Instead of spending hours or days downloading gigabytes of history for a full node, lightweight clients could verify the whole chain almost instantly. The catch? Someone has to foot that massive upfront compute bill to generate the proofs first.
