The Spanish Red Cross launches RedChain, a blockchain-based aid distribution system ensuring real-time donor transparency while protecting recipients’ identities. ERC-20 aid credits issued on the Ethereum blockchain replace paper vouchers, offering privacy for beneficiary data offchain. Transparency without compromising privacy is key. Donors can track fund allocations without knowing recipients’ identities.

RedChain addresses humanitarian donors’ demand for verifiable aid flows, ensuring assistance reaches intended recipients without sacrificing their privacy. Recipients receive digital credits on their phones for discreet transactions at participating merchants. The system aims to prevent vulnerable communities from becoming data sources and maintain dignity for aid recipients.

RedChain utilizes blockchain as a public notary for aid distribution, with ERC-20 tokens representing allocated aid onchain while spending records and eligibility checks remain offchain. BLOOCK operates a blockchain as a certification layer, ensuring the integrity of records without revealing underlying data. Billions Network provides zero-knowledge credential layer for recipient privacy.
