validityBase

vBase is a set of tools for turning historical data into the equivalent of a live, timestamped movie — thus giving future users confidence in its integrity and honest presentation.

vBase lets you credibly prove when data was created, that it’s complete, and that it hasn’t been selectively presented. This is especially valuable when showcasing data with predictive power, which is often marketed based on past performance.

While vBase tools are very general and have broad applications, we are most focused on helping users showcase the value of their alternative data, trading signals, and investment track records.

vBase solves the problem of establishing third-party trust in historical data.

In fields where predictive models or signals are evaluated based on past outcomes, it’s notoriously difficult to verify whether historical results are truly predictive, or simply retrofitted to look that way. Without transparency, third parties can’t tell the difference between real foresight and selective presentation.

vBase allows anyone to build an independently verifiable record of past data, by building cryptographic proof of the data’s timestamps, completeness, and honest presentation.

A few examples:

• Quant Manager Marketing a Track Record
  A quant manager presents performance results to investors. But unless the strategy was run inside an audited fund, there’s no reliable way for allocators to distinguish between a live record and an overfit backtest.
  
  With vBase, the manager can show an independently verifiable trading history. This builds trust, shortens diligence cycles and increases the likelihood of raising capital or landing a role.

• Alternative Data Vendor Selling Predictive Signals
  A data vendor claims its sentiment or satellite data predicts commodity prices. But post-hoc claims are easy to fabricate, and buyers are rightly skeptical.
  
  The standard fix, a 6-month live trial, is slow and resource-intensive.
  With vBase, the vendor maintains a continuous, verifiable live record. Every meeting with a potential buyer starts with a timestamped track record already in hand. That speeds up trials, reduces diligence overhead, and shortens the time to deployment and revenue.

• University Hosting a Student Trading Competition
  Professors want a fair competition that gives students a credible performance record for recruiting.
  
  vBase makes the contest provably fair and generates a verified track record for each student. Our live dashboards turn this record into a shareable portfolio, letting students showcase their skills credibly and easily to employers or investors.

• AI Researcher Publishing Model Results
  
  An AI researcher publishes a new model for forecasting Chicago weather. But unless the historical predictions were timestamped and preserved in real time, readers must take it on trust, and may worry about omitted outliers or selective reporting.
  
  With vBase, the researcher can present a live, timestamped history of predictions, provably complete and untampered — turning skepticism into confidence.

vBase is used to create independently verifiable histories of financial data, making it easy to prove when signals, models, or performance records were generated and that they haven’t been selectively edited. It’s especially useful for showcasing the value of alternative data, quant signals, and investment track records with credibility.

Beyond finance, vBase can be valuable in any domain where trust in historical data matters, such as academic research, AI model development, or compliance reporting, by providing a transparent and tamper-evident audit trail for historical data.

vBase makes any dataset independently verifiable by publishing a cryptographic fingerprint (hash) of the data to a public blockchain. The timestamp is secured by the blockchain’s global consensus process, with thousands of independent nodes agreeing on and recording the time. This makes it tamper-proof and independently verifiable.

By creating a sequence of stamps over time and linking them to specific datasets, vBase enables the construction of historical datasets that are provably point-in-time and complete.

Because user stamping histories are also verifiable, vBase makes it easy to detect selective presentation.

As a result, someone presented with vBase stamped data can be sure that the data they’re seeing is point-in-time, complete, and free from selective presentation.

vBase doesn’t assess the content or quality of your data. It simply proves when the data existed, that its historical record is complete, and that it’s been honestly presented.

Because vBase publishes cryptographic fingerprints to a public blockchain, these claims are independently verifiable — anyone can check them without relying on vBase.

This independence matters: it removes the need to trust vBase in high-stakes situations, and it ensures your verified track record remains provable even if vBase no longer exists.

vBase never needs to see or store your data to create a verifiable record. It works by processing a cryptographic fingerprint (hash) that proves the data existed at a specific time — without revealing any content. Many clients submit only hashes, so we have no access to the underlying data.

For users who opt into storage, management, or display features, sharing data with vBase is optional and fully controlled by the user.

No, only a cryptographic fingerprint (hash) of your data is published to the blockchain, not the data itself. This hash proves the data existed at a specific time but reveals nothing about its content. Your data remains private and local to your machine.
