Bound Witness

Cross paths, and save the data.

To put it simply,

when two devices that aren't related or connected each detect one another, and then independently report that they saw each other, each one proves that they both really were in the same place at the same time.

XYO Network reports this interaction as a bound witness.

Bound witness interactions can include other data that helps increase the value of the bound witness. Things like time and location improve the data which can be used in the bound witness, and help prove what the bound witness asserts. For example, if someone is looking for information about when two devices crossed paths, if they...

  1. Detected each other and say they detected each other
  2. Report the same approximate location
  3. And say that A and B happened at the same approximate time

...that proves they really did interact in a certain place at a certain time.

A real world example of a bound witness is coming soon!

What is a Bound Witness to a developer?

Any interaction between 2 or more sentinel nodes that is within proximity. This proximity provides a zero-knowledge proof that sentinel nodes are where they say they are. This interaction is at the root of the proof of origin chain and is needed to raise the confidence of any data that the sentinels are broadcasting (such as time, temperature, etc).

Without bound witnesses there can be no certain proof of location and would not start and/or be included in a proof of origin chain by the Bridge node.
