On February 3rd, CoinWorld reported that the Spanish Red Cross has launched RedChain, a blockchain-based aid distribution system. This system aims to provide donors with verifiable transparency regarding the flow of funds while protecting the privacy of recipients. Developed in partnership with infrastructure provider BLOOCK and zero-knowledge credential company Billions Network, RedChain replaces paper vouchers and prepaid cards with ERC-20 aid credits issued on Ethereum. Recipients receive their credits via mobile wallets and can use QR codes for payments at participating merchants.
