RedChain uses Ethereum-based ERC-20 tokens to replace paper vouchers, with QR payments and off-chain data storage for privacy and blockchain transparency.
The Spanish Red Cross has introduced RedChain, a blockchain-powered aid distribution platform designed to modernize humanitarian assistance. Supported by BLOOCK and Billions Network, the system issues ERC-20 tokens on the Ethereum blockchain, replacing traditional paper vouchers and prepaid cards. Beneficiaries can make QR code payments while personal data remains stored off-chain to protect privacy. Transparency is ensured through public blockchain verification, reflecting a growing trend toward blockchain use in aid and social impact sectors.
