Spanish Red Cross Launches Blockchain-Based Aid Distribution System

The Spanish Red Cross has introduced a blockchain-based aid distribution system named RedChain. According to Odaily, this system is supported by BLOOCK and Billions Network, aiming to digitize the entire process from donation to aid distribution. RedChain utilizes ERC-20 tokens on the Ethereum blockchain to replace paper vouchers and prepaid cards, allowing beneficiaries to make payments using QR codes through mobile wallets at partner merchants. Beneficiaries' identity information and case records are stored in the Spanish Red Cross's off-chain system, while the public blockchain is used solely for verifying transaction hashes, timestamps, and integrity proofs. This approach ensures transparency in the flow of donated funds while safeguarding the privacy of the beneficiaries.
