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 — 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 — 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.

Microsoft OneDrive features and specs

  • Integrations
    OneDrive is seamlessly integrated with Microsoft Office applications, allowing for easy saving, accessing, and sharing of documents directly from Word, Excel, PowerPoint, and other Microsoft 365 apps.
  • Cross-Platform Availability
    OneDrive is accessible on various platforms, including Windows, macOS, iOS, Android, and through web browsers, ensuring users can access their files from virtually any device.
  • Storage Options
    OneDrive offers flexible storage options, ranging from the free plan with 5GB of storage to various paid plans that provide significantly larger storage capacities.
  • Collaboration Features
    OneDrive supports real-time collaboration, allowing multiple users to work on a document simultaneously, with changes being updated in real-time.
  • Security
    OneDrive provides strong security features, including file encryption both in transit and at rest, as well as advanced data loss prevention and compliance capabilities.

Possible disadvantages of Microsoft OneDrive

  • Offline Access
    Although OneDrive has offline access capabilities, users sometimes experience sync issues where files aren't updated or downloaded properly when connectivity is restored.
  • File Size Limit
    OneDrive imposes a file size limit for uploads, which can be a drawback for users needing to store and share very large files.
  • Cost
    While OneDrive offers a limited free plan, the more useful features and larger storage capacities require a subscription, which might be costly for some users.
  • Complexity
    For some users, especially those not already familiar with Microsoft products, OneDrive's UI and integration features can seem complicated and overwhelming.
  • Dependency on Internet Connection
    As with most cloud-based services, an active internet connection is required to access and sync files, which can be inconvenient in areas with poor connectivity.

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.

    On Windows 10 by default

    For hosting common files it's ok. Also it is on Android too do, great to transfer files between your Windows and your phone. But if you want better security you have to subscribe a monthly offer.

    Pros:    Well designed|Free basic plan|Multiple platforms
    Cons:    Data protection and security|Expensive

Another benefit is OneDrive’s file versioning, which you can use to access older versions of your files and restore them. OneDrive also has this Personal Vault, where you can add your files and have them locked with MFA and apply encryption – not zero-knowledge encryption, though.
