Dòng đầu là dấu vân tay bạn đang tra. Mỗi dòng sau là một phép tính SHA‑256 ghép hai mã lại — ai cũng tính lại được bằng máy tính của mình, và kết quả cuối phải đúng bằng gốc đã công bố.

The type of work, date and time, text and original photos of each record are hashed into one digital fingerprint. Change a single character and the fingerprint is completely different.
Every record carries the previous record’s fingerprint, forming a hash chain. Quietly change one character and the chain breaks.
At the end of each day (around 23:55–23:59) the fingerprints of all lots with new records are combined into one Merkle root and published on the blockchain anchor page. If the server is down, the anchor is made when it restarts.
The root is submitted free of charge through OpenTimestamps into Bitcoin. This root is already in a block: no one — not even Nguồn Xanh — can backdate it.
Not from the hash — hashing is one-way; only easily guessed content can be brute-forced, which is why personal names and phone numbers never enter the log. But tracing back to verify does work: with a label serial, lot code or record id you can find the record, its anchor date and the accompanying proof. From a root you can only check one specific record, never list anyone else’s.
