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.

Dropbox features and specs

  • Ease of Use
    Dropbox offers a user-friendly interface that makes file sharing, syncing, and storage simple for users of any technical skill level.
  • Cross-Platform Compatibility
    Dropbox supports multiple operating systems including Windows, Mac, iOS, and Android, making it accessible from almost any device.
  • Collaboration Features
    The service includes features like shared folders, file comments, and real-time collaboration on documents, which are ideal for team projects.
  • File Versioning
    Dropbox maintains previous versions of files, allowing users to recover older versions if needed, which is helpful in case of accidental deletions or edits.
  • Third-Party Integrations
    The platform integrates seamlessly with various third-party apps such as Microsoft Office, Slack, and Trello, enhancing its utility in workflow management.
  • Strong Security Measures
    Dropbox offers robust encryption both at rest and in transit, along with two-factor authentication to secure user data.

Possible disadvantages of Dropbox

  • Cost
    Dropbox can be expensive, especially for businesses or advanced individual users who require more storage than what is available in the free plan.
  • Privacy Concerns
    There have been concerns around Dropbox's privacy policies and data handling practices, which might not be ideal for users particularly concerned about privacy.
  • Storage Limits
    The free version of Dropbox offers limited storage capacity (only up to 2GB), which may not be sufficient for users with extensive storage needs.
  • Sync Performance Issues
    Some users have reported issues with the speed and reliability of file syncing, which can be disruptive, especially for large files or bulk uploads.
  • File Size Restrictions
    There are file size limitations for both free and certain paid plans, which may be inconvenient for users who need to store or share particularly large files.
  • Limited Offline Access
    While Dropbox allows files to be made available offline, the process is not always straightforward and can lead to accessibility issues when internet access is not available.

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.
  • Decentralized Verification
    Signature verification does not rely on a single centralized authority, which can increase transparency and allow independent verification of document authenticity.
  • 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.

    Dropbox: You absolutely NEED backups. Ideally, both physical and cloud backups, because if you only have one backup, you're not backed up.
