# Proof of Personhood (POP) Algorithm

**Approach**

POP scoring for each user and organisation based on multiple touchpoints.

**Assumptions**

* Users and organisations will not all want to use the same method of POP
* there may be one, many or a combination of proof of personhood methods that are valid
* some proof of personhood methods are valid contributors to POP score but imperfect as a sole point of reliance.
* Institutional registries (eg public Company registries) are assumed not to have third party verification until approved as part of algorithm
* Users and organisations will claim false credentials until

**Algorithm Components**

* Biometrics
  * worldcoin
* Approved National/International/Institutional credentials
  * ID cards / driving licence / BankID (Sweden) & other national ids
  * Stock market indices (ie reliance upon public company verification)
    * note that LEI (Legal Entity Identifier) & National Company Registries are unlikely to offer a valid POP component and each will need approval case by case
  * OpenBanking / Bank Statements / AML Credentials (eg from Coinbase if can partner)- digital integration
  * KYC / AML on platform (subject to budget constraints)
* Social-graph
  * Connections on Profile.io including:
    * endorsements from other trusted users and organsations
    * badges from issuer organisations
