Not quite.
Think of OCEN (Open Credit Enablement Network) to be a platform which is very similar to UPI (although it is for lending not payments). UPI has many players using it like Gpay, PhonePe & BHIM. Similarly OCEN will have many players using it. Ugro will be one of them
OCEN is a common set of rules/language that all the lenders, credit bureaus, account aggregators and Loan service providers will adhere too. This is help provide credit in a plug and play model - where information is used as a collateral. Information such as bank statements, GST filings, vendor invoice data, receivable time period. Additional, it removes the requirement to have a bi-lateral partnership with every lender & loan service providers.
Similar to how UPI is owned by a non-profit organisation called NPCI, OCEN too is being housed by a non-profit organisation called CredAll
