BLUMFI

A platform offering blockchain-based courses and credentials for lifelong skills.

Problem Statement

Rossmarie is bringing underbanked women onchain through verifiable education and community. Our app uses World ID for secure identity, EAS and NFTs for onchain reputation w/ token gated access. Yellow Network unlocks the future: walletless onboarding, fiat support, and zk-powered access. Today, we reward verified learners. Tomorrow, we bank and teach finance to the unbanked.

Solution

ERC-721 NFT-Grants token-gated access (ownership required) World ID-Proves user uniqueness via Worldcoin and Mini App EAS (Attestation)-Verifies that the user has a valid on-chain attestation (e.g., enrolled or verified) Yellow Network-(TBD) for fiat onboarding (e.g., buy NFT or pay with a card without wallet)
