What is a Stamp?

vBase tools help anyone create and verify timestamped data fingerprints, which can be used to prove when someone had particular data. We call these timestamped data fingerprints vBase Stamps.

Conceptually a vBase Stamp is just a unique fingerprint of your data published with your signature at an independently verifiable time.

vBase also enables the aggregation of Stamps into Collections. Each Collection is a set of Stamps with independently verifiable membership.

What Gets Published?

A vBase Stamp publishes the following:

1. The blockchain address of the user making the stamp

2. A fingerprint of the underlying data records (aka a content identifier, aka a cryptographic hash)

3. (optional) A collectionID, which is a hash of the dataset name to which the record belongs see what is a collection below.

Here is a graphical example of a vBase Stamp

What is a vBase Collection?

vBase also enables the aggregation of Stamps into Collections. Each Collection is a set of Stamps with independently verifiable membership.

By aggregating Stamps into Collections, you can identify which of your on-chain fingerprints belong to which dataset. This is useful in verifiably defining datasets like trading strategies, experimental results, sensor readings, risk models, etc.
