Proof of existence
BlockchainSign is a blockchain timestamping service for people holding documents they cannot hand over.
Conventional options all require custody: a copyright office wants a deposit copy, a notary wants to see the paper, an e-signature platform wants the file on its servers. BlockchainSign never receives the file at all. The document is hashed with SHA-256 in the user's own browser using the Web Crypto API, and only the resulting hash is written to the Ethereum blockchain.
The result is a certificate file recording the hash, the transaction and the timestamp. Because each certificate is its own Ethereum L1 transaction, with the payload hash readable as UTF-8 on a public block explorer, verification does not run through the vendor's portal: if BlockchainSign shut down, existing certificates would still verify.
There is no subscription and no cryptocurrency wallet involved. Certificates are bought as credits with a card and spent when needed. Credits are valid for 12 months; an issued certificate never expires.
Key points
What it does not do. A timestamp proves that a file existed in that exact form at that time โ existence and integrity. It does not prove authorship or ownership, and it is not a substitute for copyright registration. There is no API or integrations yet, and no eIDAS qualified timestamp.
Windows BitLocker BlockchainSignBitLocker is highly recommended for businesses and individuals who prioritize data security, especially those using the Windows operating system. It is particularly useful for organizations managing sensitive information that requires compliance with standards like HIPAA or GDPR.

The initial yes. Once encrypted you can trigger remote via intune/sccm/MDM https://docs.microsoft.com/en-us/windows/security/information-protection/bitlocker/bitlocker-overview. - Source: Hacker News / about 4 years ago
On linux it you can achive it via LUKS, on windows with the help of bitlocker or preferably veracrypt. Source: over 4 years ago
What os are you using? If it happens to be a โproโ version of windows you could use bitlocker full-drive encryption which is built-in. There is one known vulnerability which involves gaining access to the RAM within seconds of shutdown, but thatโs easily averted by keeping the computer in your possession for a minute or two after shutting it down.
