    Frequently Asked Questions

    What is vBase?

    vBase is a platform for creating auditable provenance information for data and digital objects.

    vBase allows anyone to credibly show others not just the current state of their data, but how and when it came to be that way.

    What are the uses of vBase?

    Auditable provenance can be very useful in a variety of applications. The vBase tools are
    general purpose and can be used by anyone who would find auditable provenance for their
    data useful.

    vBase allows anyone to show the authenticity of their data objects, and to prove their
    provenance to 3rd parties.

    A few areas where this is useful include:

    • Financial data
    • Digital credentials
    • Journalism and digital media
    • Academic research
    • Medical trials
    • Deepfake AI
    What is data provenance?

    Provenance is information about where and when data originates. It is a form of metadata.

    The vBase platform allows for the auditable recording of the following provenance information:

    • What was the data
    • When did it exist
    • Who published it
    • Any additional user-defined attributes or labels

    vBase allows this provenance information to be immutably recorded, timestamped and later verified easily and scalably.

    Why is the provenance of digital objects important?

    When you meet someone, it often helps to understand where they’re from, their occupation, their age, and other characteristics about them that may not be immediately observable. Data works the same way.

    For data to be credible, it’s often necessary to know where it came from, when it was created, and what set of data it belongs to.

    For example, a bridge inspection report isn’t very useful if you aren’t sure when it was created. Similarly, a financial model is only meaningful if you can be sure it wasn’t created after the stock market results were known.

    vBase is a modern, blockchain-based data provenance platform. It can create and validate tamper-proof timestamps in a scalable, secure way.

    A few examples:

    • Create provably point-in-time data and predictions
    • Establish authenticity of images and videos
    • Manage document reconciliation and auditable long-term storage
    • Create 3rd party verifiable research data
    • Comply auditably with data retention requirements
    How does vBase work?

    vBase enables the recording of digital object provenance by helping anyone publish and verify digital object fingerprint information on permanent and open storage media like IPFS, distributed ledgers and blockchains.

    What makes vBase different?

    vBase has a variety of advantages relative to traditional methods of recording provenance.

    • Auditably tamper-proof – provenance information is globally trustworthy once it’s created because it comes about via a verifiably tamper-proof process
    • Strong privacy guarantee – vBase never sees your data
    • Long-term valid – even if vBase disappears, your provenance information can be easily validated practically forever
    • Extremely convenient – provenance information sits separately from underlying data, meaning you don’t have to move your data, and the process of creating and validating provenance information scales easily in a platform-agnostic fashion
    • No walled garden – vBase provenance metadata can be created and validated with open 3rd party tools. vBase is just an easy button to make the process easier
    How do I start using vBase?

    How much does it cost?

    With a free vBase account, you can make up to 100 stamps for free each month.

    If you use up the free tier, you can upgrade to our $49/month plan which offers 400 stamps/month, with additional stamps just $15 per 100.

    We also offer discounts for enterprise-scale use. Please get in touch with for more information.

    Why is it called vBase?

    The v is for validity. vBase is a base for valid and trusted communication about data and digital objects over the internet

    How do I make my data more trustworthy for customers?

    Can users validate my data for the long-term?

    Does vBase see my data?

    Have you tried making portable data provenance using vBase?

    vBase timestamps and signatures are provably tamper-proof forever

    No need. vBase creates auditable provenance without seeing your data.
