PreBlock is the predictive block-template engine for Bitcoin pools. Bitcoin Knots filters the spam upstream, our scorer ranks the rest, and DATUM injects the optimised template — all on a single machine. No GPU farm required.
We don't run Bitcoin Core — we run Bitcoin Knots. It filters Ordinals, Inscriptions and other non-financial payload before our predictor ever sees the mempool. The result: pool operators mine the transactions that actually pay, not data scribbles disguised as transfers.
Every component is purpose-built for predictive mining on a single Sphere node — no GPU clusters, no obscure dependencies, no external SaaS.
Live ZMQ stream sorted by effective fee-rate. Three lookahead buckets (h+1, h+2, h+3) at every tick. Legacy-input + dormancy detection as second-order signals.
Real-time view of pool connection, stratum status and worker hashrates. Connected workers, last-seen timestamps, kumulated TXs delivered to OCEAN.
Live worker comparison, hour-champion award, 24h history. Devices ≥ 1 TH/s individual; smaller ASICs (Bitaxe, LuckyMiner, Nerdminer) aggregated.
Hit-rate per block, outlier filter for empty blocks & reorgs, multi-block comparison (+1/+2/+3). CSV & PDF export for full audit trails.
Claude Sonnet 4.5 summarises performance data scientifically on demand — strict English output for international buyers, configurable language.
Real-time alerts on new blocks, hit-rate drops, RPC failures, DATUM disconnects. Sunday 23:00 (Berlin) auto-PDF weekly report.
DE/EN ships native. Smart hybrid auto-translate for additional languages on demand. Translations cached permanently — generate once, always available.
Service-status for backend, worker, DATUM, Bitcoin Core, MongoDB. Disk, RAM, CPU and ZMQ heartbeat. Auto-refresh every 30 seconds.
The PreBlock Core includes the Knots-filtered mempool radar, DATUM gateway monitor, hashrate race, ROI calculator and license system. Specialised capabilities are sold as add-on modules. Each module is an independent license entitlement keyed to your Authenticity Key.
"Compare PreBlock's optimised template against the default Core template in real time. +0.3–1% fee uplift, provable in A/B mode."
"Run multiple DATUM gateways in parallel. Compare PreBlock templates vs ViaBTC, Foundry, AntPool side-by-side."
"SHA-256 audit logging, reorg-aware hit-rate, exportable PDF reports for your auditors and investors. Trust-anchor for institutional DD."
"Historical mempool replay. Simulate ROI on 30 or 90 days of past data before you spend a single satoshi."
"Telegram, Slack and webhook alerts. Daily / weekly auto-PDF. We wake you only on anomalies — sleep through the routine."
"Brand it your way. Run customer portals. For resellers and Mining-as-a-Service providers."
"Vendor on-call. Priority bug-fix. Monthly health review. For pools who cannot afford downtime."
Module prices apply per license. Cross-module discounts available · Bundles negotiable on commercial discussion.
Live market data (BTC price via CoinGecko · network hashrate via blockchain.info). Adjust your inputs — the math is transparent and runs entirely in your browser. Conservative pitches assume 0.5–1.5% uplift; aggressive scenarios go up to 3% or more during volatile fee markets.
* Estimator. Actual results depend on mempool dynamics, pool routing, and hardware availability. Conservatively modelled.
Bitcoin Core streams transactions via ZMQ. PreBlock's Mempool Streamer buckets them into three forward block templates. On every tip change, the predictive template is delivered to your OCEAN pool through DATUM Gateway — typically in under 50 ms.
This product is not a startup deck. It's the mining arm of a personal research lab — born from a real loss, hardened by science, sharpened on hardware.
In 2025 I was scammed out of €9,500 worth of Bitcoin. The polite response would have been to file a police report and move on. I chose the other path: I went after the keys.
That obsession became Wallet-Master — a personal research lab for Bitcoin internals. I built tooling around address-space pattern recognition, transaction forensics, mass key-candidate generation on a GPU rig (7× P106-16, 24 TB of cold storage), and a private node infrastructure to verify everything against the live chain.
"I never recovered the €9,500. But I learned how Bitcoin actually works — from the bottom of the protocol upward, not the top of a slide deck downward."
Along the way it turned into a Master's thesis: mass-production address analysis, statistical evaluation of search spaces, AI-assisted pattern detection across community-reported puzzle ranges. The puzzles were a side quest — could one narrow the address space by detecting structural fingerprints? I worked on the thesis until four months ago, refining the methodology so the lab could feed back into it.
One of those side roads led me to the mempool. Why do blocks look the way they do before they exist? That question — asked from a forensics mindset rather than a mining-operator mindset — became PreBlock. The same techniques I used to narrow address spaces, I now use to narrow which transactions actually make it into the next three blocks.
PreBlock is the first product from the Wallet-Master lab to leave research and enter commercial release. It is built for buyers who recognise that edge in Bitcoin doesn't come from bigger fleets — it comes from understanding the protocol from a different angle.
