Open Mine exists because hosted Bitcoin mining has become an information-asymmetry machine. Buyers can't tell who delivers what was promised. Providers who deliver on their commitments can get out-competed on marketing by those who don't. We're fixing that with one simple thing — make delivery legible.
Open Mine is a thin layer on top of the providers themselves. We don't own datacenters. We don't hold custody of miners. What we do is run the Stratum Router, settle the ledger, and onboard providers who are willing to stake their reputation on delivery numbers anyone can verify.
Browse miners from every vetted provider. Pick the one with the right hosting price, jurisdiction, and hardware. Top up your balance. Buy. The router connects your miner to a pool of your choice and the ledger debits hosting daily. Diversify future purchases across providers from one account.
List your inventory in one place. We bring buyers who've already understood counterparty risk. No more chasing AR — clients prepay, and the ledger debits hosting for you. Your provider page compounds reputation as you deliver.
Double-entry, event-sourced. Deposits credit your balance. Hosting fees, revenue, repairs — all settle against the same accounts. Statements you can audit any time.
stratum.openmine.io sits between your miner and your chosen pool. We see exactly what hashrate gets delivered, vs. what the provider promised. Daily delivery reports per provider — public.
Every miner in the marketplace declares hashrate, efficiency, hosting price, and provider. No fine print. No surprise charges. No churn.
Open Mine makes commercial prices and provider responsibility explicit before purchase and then records delivery after purchase. Clients compare providers in one marketplace instead of relying on scattered sales decks.
Open Mine removes custom policy text per miner from listings. The provider still hosts the hardware and is accountable for delivery over time.
Stratum Router records what the configured miner flow delivers. The router, reports, and ledger use the same delivery record, so outages and provider performance are visible instead of hidden behind a spreadsheet.
Open Mine is led by Cyberian Mine — a six-year hosting operator that ships some of the cheapest, coldest hashrate on the network. We're building the platform we wish existed when we started.
