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

  • The file is never uploaded โ€” only its SHA-256 hash is transmitted
  • Recorded on Ethereum L1, one transaction per certificate
  • Verifiable on a public block explorer, independently of us
  • No subscription, no renewal, no wallet, no crypto knowledge needed
  • A free SHA-256 file hash generator is available with no account
  • Available in English, French, German, Spanish and Portuguese

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.

BlockchainSign features and specs

  • Blockchain-Based Security
    Utilizes blockchain technology to timestamp and verify document signatures, creating an immutable record that can enhance trust and reduce the risk of tampering or fraud.

  • Cost-Effective for Digital Signing
    Blockchain-based signing solutions like this often provide competitive pricing compared to traditional e-signature platforms, especially for high-volume users.
  • Tamper-Evident Records
    Once a document is signed and recorded on the blockchain, any attempt to alter it becomes detectable, providing strong evidence of document integrity over time.
  • Global Accessibility
    As a web-based platform, it can be accessed from anywhere with an internet connection, making it convenient for international business transactions and remote signing needs.
