Spanish Red Cross launches privacy-first blockchain aid platform
The Spanish Red Cross is rolling out RedChain, a privacy-preserving blockchain aid system that gives donors cryptographic proof of impact without exposing beneficiary identities.
The Spanish Red Cross (Creu Roja) has deployed a new blockchain-based aid distribution system, RedChain, that promises real-time donor transparency without exposing the identities of the people receiving assistance.
According to a release shared with Cointelegraph, the platform, developed with Barcelona-based infrastructure provider BLOOCK and zero-knowledge credential firm Billions Network, aims to digitize “the entire aid lifecycle from donation to disbursement.”
It replaces paper vouchers and prepaid cards with ERC‑20 aid credits issued on the Ethereum (ETH) blockchain, delivered to a mobile wallet that can be used at participating merchants via quick response (QR) codes.
