TelePortUsSecurity & EncryptionTelePortUsSecurity & EncryptionTelePortUs doesn't ask you to trust us — it gives you a way to check. Every access to patient data is recorded in an audit chain that is anchored to the Bitcoin blockchain every single day.
Each time patient data is accessed — who, what action, which record, when, from where — it's written to an immutable SHA-256 hash-chained audit log. Change one past entry and every hash after it breaks.
Once a day at 2:00 AM PT, the current head of the audit chain is hashed into a single fingerprint representing the entire log up to that moment.
That fingerprint is timestamped on the Bitcoin blockchain via OpenTimestamps — a free, community-run service that batches thousands of hashes into one transaction. Your verification is permanent and costs us nothing.
Anyone can verify the receipts with the free OpenTimestamps tool — no account, no server access, no trust required. If the audit log was tampered with at any point, the anchor won't match.
Each row is the daily head hash of the audit chain and its OpenTimestamps receipt. The receipts live in our public code repository — download one and verify it yourself.

The receipts are stored in the audit-anchors/ directory of our repository. With the free OpenTimestamps tool:
# install the official tool (macOS, Linux, Windows all supported) pip install opentimestamps # verify a daily receipt ots verify audit-anchors/2026-08-11.ots # output: "Success! Bitcoin block 901234 attests existence as of 2026-08-11..."
That's it — no account, no server access, no trust required. If the audit log had been altered at any point, the blockchain anchor would no longer match. This is the same technology used to prove tamper-evidence in legal, financial, and government contexts worldwide.
