Odexnium
A real-time Bitcoin network dashboard: live blockchain, mempool, fees,
mining economics and block verification in a single page.
Data
All chain and market data comes from the public
mempool.space REST API and refreshes every 30 seconds —
blocks, mempool composition, fee estimates, pool stats and the BTC/USD price.
Nothing is stored server-side; this page is a single static HTML file.
Security tiers
Blocks crystallize as they sink into the chain: Forged (just mined)
→ Cooling → Hardened → Immutable (9+
confirmations), reflecting how reorganization risk drops with depth.
Energy & profitability model
Finding a block at difficulty D takes on average
D × 2³² hashes. Energy is estimated at a network-average
fleet efficiency of 25 J/TH, priced at a median industrial
mining rate of $0.05/kWh, and compared against the coinbase
reward (subsidy + fees) at the live BTC price. Electricity only — hardware,
hosting and staff are not modeled.
Miner attribution
Pools are identified from coinbase signatures by mempool.space. HQ and
facility locations come from a hand-kept registry and are approximate —
pooled hashrate aggregates member facilities worldwide.
Verification
Every block detail view rebuilds the raw 80-byte header and checks
SHA256(SHA256(header)) against the block hash in your browser
via the Web Crypto API. You can also download the header and verify it yourself.
Disclaimer
Energy, cost and profitability figures are rough educational estimates,
not financial advice or audited data.
