Instead of relying on risk data locked within proprietary databases, Growr provides an open credit record model, which also preserves the privacy of the borrowers through a self-sovereign identity.

How does it work?

Protocol mechanics

Self-sovereign credit record

A digital identity, based on W3C’s DID and VC standards, owned and managed by the user, storing their credentials, credit history and financial health tools for education and personalized advice.


Wallets, financial institutions, FinTech companies and non-financial providers such as merchants, telcos and gig economy platforms, facilitating access to the protocol through a simple and secure way for borrowers to easily apply and obtain fair loans.

Trusted party

Trusted parties (such as value chain partners, financial providers, telcos, merchants, NGOs) issue cryptographically verifiable credentials to the borrowers about their financial and non-financial life that are stored in their self-sovereign financial identity.

Risk assessor

Risk assessors are third parties trusted—and most often owned—by the lenders that perform verification of borrowers’ credentials and assert their eligibility to receive a loan. Risk assessors produce a credit score for each project that is used by the lenders in their automated decisions, and that investors receive yield from real economic activty.

Decentralized marketplace

A decentralized infrastructure for lending and borrowing on top of the Bitcoin network, with open access for everyone. The key differentiators of the Growr protocol are that loans are provided against verified credentials from borrower’s self-sovereign financial identity and credit record, instead of requiring over-collateralization.


A traditional finance institution or a FinTech that is providing micro-lending through the decentralized marketplace with specific conditions and eligibility criteria. Lenders make their financing decisions based on the credit record of the borrower, provided by the risk assessors.


A decentralized finance protocol, institutional or individual investor pooling funds who deploy capital as senior tranche and delegate the actual lending activity to the lenders. Investors get rewarded with yield from real economic activity based on the pool profitability. Generally, a pool yield will tend to be lower that the project yield due to the wholesale lending nature of the pools.
