Leiden Trezors an Bitrot?

Ich habe einen Hintergrund in der Welt der Systemadministratoren. Ein nicht triviales Problem in diesem Bereich ist das so genannte Bitrot, bei dem Bits auf der SSD oder HDD zufällig umkippen und dadurch Daten beschädigen. Wir verwenden spezielle Software, um diese Bits zu überprüfen, und machen viele Backups unserer Daten für den Fall, dass etwas passiert (und RAID, RAID ist kein Backup). Bitrot tritt häufiger auf, wenn die Laufwerke eine Zeit lang ausgeschaltet waren.

Ein Bitflipping in einem privaten Schlüssel auf einer Trezor würde ihn unbrauchbar machen. Ist dies ein Problem, über das ich mir Sorgen machen müsste, wenn ich eine Trezor verwende, insbesondere wenn ich sie monatelang oder jahrelang nicht an die Stromversorgung anschließe?

Kann jemand aus eigener Erfahrung bestätigen, dass die Daten auf seinem Trezor zufällig beschädigt wurden?

Why would it be useless if you can restore the wallet with the seed you’ve safely secured?

I personally, audited the code path. The calling program (Suite) has the TXN data to be signed and passes it to the Trezor. The only thing the Trezor returns is the signature. If corruption happens in that path the signature would show as invalid and be rejected by the mempool.

Also the firmware is encrypted. If it rots at rest the firmware decryption would fail.

If left at rest for 50 or 100 years I would fully expect to see some failure at power up. Hence, keep your seed mnemonic and passphrase safe.

If you are doing disaster recovery planning. Trezor keeps an emulator up to date. If you trezor dies you can break your seed by loading it into the software emulator and still access all your coins.

Does it really matter? If you have your seed phrase you never lose your funds even if your Trezor is vaporised.

Hardware wallets are not data storage devices. You’re supposed to store your data (seed words) separately (and offline). The ecosystem is designed to operate even if you lose your hardware wallet or it gets vaporized into atoms. They are interchangeable, you buy another and restore it manually.

If you’re relying on the hardware wallet as your only copy of the seed/private keys, you’ve already lost before you even began. You’re doing it all wrong. Bitrot is the least of your worries in that case, because you’re going to possibly lose your money anytime the wallet gets reset, damaged, possibly if updated etc.

Short answer, yes. All digital storage will have bit rot if left for long enough. That’s one of many, many reason for why you have a recovery seed.

Honestly, I think that’s exactly what happened to the ledger user who lost all his Bitcoin, when his ledger sent the Bitcoin to a random change address

I imagine other components to fail before bits start to flip.

That’s why we have a seed phrase.

You seem to be confusing but flipping with electron tunnelling. All solid state devices will rot.
