Most storage hands you a file and hopes for the best. Superfecta seals every file with a SHA‑256 fingerprint the moment it arrives — then re‑checks that fingerprint, around the clock, for as long as the file lives. If a single bit ever drifts, we know instantly.
Feed any file — a photo, a contract, a database backup — through SHA‑256 and you get back the same thing every time: a 256‑bit value written as 64 hexadecimal characters. The same input always produces the same fingerprint, and it's effectively impossible to work backward from the fingerprint to the file.
A one‑kilobyte note and a hundred‑gigabyte archive both produce exactly 64 hex characters. The fingerprint never grows with the file.
Finding two different files that share a SHA‑256 fingerprint is, in practice, beyond reach — so a matching hash means the bytes match.
Change a single character and roughly half the fingerprint changes. There's no "small" edit that slips by unnoticed.
Type into the box and watch the fingerprint redraw on every keystroke. This is the exact algorithm that seals every file on Superfecta — computed right here, on your device.
Here's what makes hashing trustworthy. We take your text below, then quietly change one single character. Watch how the two fingerprints share almost nothing — the differing characters are marked in coral.
This is why a stored fingerprint is tamper‑evident. A corrupted byte, a flipped bit, or a malicious edit can't produce a fingerprint that's "close enough." Either the file's hash matches what we sealed, or it doesn't — there is no in‑between.
A fingerprint taken on day one only proves the file was intact on day one. The uncomfortable truth about every storage medium is that data degrades on its own — silently, with no error message — long after you've stopped looking.
Flash cells leak charge over time. Magnetic platters fade. Cosmic rays and stray electrical noise flip individual bits. Disk controllers occasionally write the wrong thing and report success. None of this announces itself — the file still opens, until one day a few bytes are wrong and it doesn't.
Superfecta keeps re‑computing each file's SHA‑256 on a continuous loop and compares it to the fingerprint sealed on arrival. The moment a stored copy stops matching its seal, we've caught the rot — early, while a clean copy still exists to restore from.
Without continuous hashing, the corruption at month 7 would sit undiscovered until the day you actually needed the file. With it, the bad copy is spotted on the very next sweep and quietly repaired — before it ever reaches you.
The instant a file lands, we compute its SHA‑256 fingerprint and record it. That seal becomes the file's source of truth from then on. Files are write‑once: stored to be read, never silently overwritten.
Around the clock, each stored copy is re‑hashed and checked against its seal. A match means the bytes are exactly what you uploaded — provably, not hopefully.
If a copy's fresh hash no longer equals its seal, that copy is flagged as compromised the moment it's checked — not months later when you open it.
A copy that still matches the seal replaces the corrupted one, and the file's fingerprint is whole again. Which brings us to a useful bonus: where those clean copies live.
The constant hashing is the product. The four nodes are what make healing possible: every file is mirrored across four independent US data centers, so when a re‑hash flags a bad copy in one place, three verified copies are standing by to restore it. No single fire, flood, or outage can take them all.
