ε-tx privacy scanner
Paste a Bitcoin address. The scanner runs 10 analysis phases against the real blockchain and shows you exactly how much an adversary can learn — in bits. Every number is computed live, not pre-generated.
Found 100 transactions spanning 15 years. This is the genesis address — it has received thousands of donations but the original 50 BTC coinbase reward is unspendable due to a quirk in Bitcoin's code.
This address doesn't share inputs with other addresses. No clustering leakage detected. The genesis address has never sent a transaction, so there are no co-spend links to follow.
The address uses P2PKH (legacy format), which narrows the wallet type. But since it's receive-only, the fingerprint is weak — we can't analyse input ordering, change position, or fee rates. Classified as legacy with moderate confidence.
Timing patterns are weak. Donations to this address come from all over the world at all hours, producing near-maximum entropy (4.48 of 4.58 possible bits). No timezone inference, no periodicity. This is what high timing privacy looks like.
67 of 100 transactions use round amounts (0.001 BTC, 0.01 BTC, etc.). These are clearly donations, not economic transactions. The round amounts are easily identifiable but since there's no spending, there's no change detection or amount correlation.
No cross-chain bridge transfers detected for this address. Privacy across chains isn't a concern here.
No CoinJoin-like transactions detected. The address uses standard transaction patterns.
A chain analysis classifier would label this as "normal-payment" with 72% confidence. Very low suspiciousness (2%). The simple transaction structure (1-2 outputs, single inputs) drives the classification toward normal payments.
After fusing all evidence sources via Dempster-Shafer, the overall privacy score is 1.2 bits (low risk). Conflict between heuristics is low (K=0.06) — the signals agree that this address has minimal exposure. The wide Bel-Pl interval (0.18 to 0.52) reflects high uncertainty from limited spending data.
Even a nation-state adversary learns only 1.2 bits from this address. The genesis address is unusually private because it has never spent — no co-spend clustering, no wallet fingerprinting from transaction structure, no timing correlation from spending patterns. The only leakage comes from amount patterns (round donations) and the legacy P2PKH format.
This demo runs 5 of 8 attack surfaces with a 100-transaction cap. The CLI analyses your complete history, adds Monero ring analysis, Lightning routing privacy, batch wallet timelines, and computes how your privacy score changes over every transaction.
