Updates from the Dev Cave: What is a Proof of Origin Chain?

One of the most common questions we’re asked has to do with one of the key concepts behind the creation of XYO: what is Proof of Origin? We go into technical detail in our white paper but, simply put, a device’s Proof of Origin Chain is its history of interactions with other XYO Network nodes.

The more interactions a particular device has, the more historical information about that device is available. Data provided by a device with a long Proof of Origin Chain is more likely to be used than data provided by a device with a short Proof of Origin Chain, all other things being equal. Similarly, a device which has interacted with a lot of other nodes is more likely to have the data it provides be used and rewarded than one which has only interacted with a handful of other devices.

There are two reasons why a long and varied Proof of Origin Chain is valuable, both from a data perspective and in terms of XYO awards:

  • Data on a longer and more varied Proof of Origin Chain can be validated with a higher degree of certainty, because outliers like false or erroneous information won’t correlate with the information provided by other nodes. In other words, there are more chances for another device to say “that looks wrong to me!”
  • You earn XYO when data your devices provide is used to answer a query. If your devices solely interact with each other, then there’s no opportunity for them to be rewarded for answering someone else’s request. The COIN app is a special case — XY is rewarding XYO to COIN app users without a full query, so there’s no archivist or diviner involved. Future iterations of COIN will be capable of a full XYO Network transaction, from a Diviner through to your Sentinels. At that point, we (XY) will essentially be querying the Network when distributing rewards through COIN.

There are, however, some times when you might want to reset your Proof of Origin Chain. By resetting your proof of Origin Chain, you’re de-linking historical information provided by a device from the data it provides in the future. Think of it as getting a new telephone number — you still have your old phone, but no one can call you if they only have your old contact information. Resetting the Proof of Origin Chain adds a level of privacy to the data you’re providing, but by doing so, you lessen the chance you’ll be rewarded for data you provide moving forward.
