# Proof of Authenticity
|
||
|
|
|
||
|
|
Proof of Authenticity (PoA) is an algorithm that allows peers to verify that people, products and statements on the ThreeFold Grid are genuine. It acts as a reputation engine to validate any information on the grid.
|
||
|
|
|
||
|
|
## Why Proof of Authenticity
|
||
|
|
|
||
|
|
Any system that contains a vast amount of information, should require proof of authenticity.
|
||
|
|
|
||
|
|
We believe users should be able to measure authenticity in relation to
|
||
|
|
|
||
|
|
- The people they connect with;
|
||
|
|
- The products and services they access;
|
||
|
|
- The information they consume.
|
||
|
|
|
||
|
|
Therefore, to automate information search in a decentralized and trustful environemnt, an algorithm that is able to scale information verification in a neutral way is required.
|
||
|
|
|
||
|
|
Proof of authenticity puts forward a very simple method to verify the genuiness of information.
|
||
|
|
|
||
|
|
Here's an example of how PoA works in a decentralized context:
|
||
|
|
|
||
|
|
- Someone fills in their profile with their personal and professional data.
|
||
|
|
- A former colleague finds their information and verifies their information as being authentic.
|
||
|
|
- Once a user gets verified e.g. 10 times, they can be trusted to be real and genuine.
|
||
|
|
|
||
|
|
The above can also apply to products, statements and more. In that sense, PoA can solve multiple digital challenges such as:
|
||
|
|
|
||
|
|
- The verifiability of information and news
|
||
|
|
- A non-biased way to rate products and services.
|
||
|
|
- website authenticity
|
||
|
|
- etc.
|
||
|
|
|
||
|
|
## Applicability
|
||
|
|
|
||
|
|
POA can be used for any type of information but one of the first ones is identity, KYC/AML is a mechanism to identify people but peer authentication is a very powerful way to extend this with.
