Live firewall · no account · forge it yourself
Don't trust us. Try to forge it.
The Fidacy payment firewall authorizes a payment against a signed mandate, issues a short-lived Ed25519 grant, and writes a hash-chained, append-only proof. Run it live below, then verify and tamper with it in your own browser, against Fidacy's public key, with no account.
1 · Run a payment through the firewall
Pick a payment above to run it through the live firewall.
4 · Beyond tamper-evident
Even we can't rewrite it.
The hash chain above proves no record can be edited without the chain breaking. But the signing keys exist, so a determined operator could in principle regenerate the whole chain from scratch. That is why Fidacy commits the chain's head to Bitcoin, a public ledger no single party controls. Rewriting the history would mean rewriting Bitcoin.
Reading the live anchor state…
No private key, no valid grant. That is the whole point: the executor never moves money without a grant it can verify against Fidacy's public key, and any retroactive edit to the audit log breaks the chain.
