The story
PreBlock is a block-template layer for Bitcoin miners. Instead of sorting every block by fee-rate and packing it broadly the way large pools do, we produce templates that focus on a materially narrower slice of the block candidates for each expected block. When a customer hits a nonce, the sealed block contains — with high probability — the transactions that actually belong there for the next chain tip, instead of a generic fee-optimised set.
The result is measurable (82.17 % Hit Rate, ~90 % Template Precision on our reference benchmark); the method behind it is our core IP and stays under NDA.
Our benchmark from 2026-08-21 09:30 CEST, measured after 16 hours undisturbed run, shows an 82.17 % Hit Rate over 129 audited blocks, roughly 90 % Template Precision and a ~97 % Chain-Rhythm Confidence signal from three independent live inputs. Live values roll hourly on our public /proof feed.
What we have not done yet is push the engine under real rental-hashpower load. Simulated telemetry can only tell us so much. We need to point 200 PH of Mining Rig Rentals and Braiins Hosting traffic at our Stratum endpoint for a solid 12 hours, watch how the template dispatch, the slice matching and the Vardiff auto-adjustment hold up, and document the entire run.
