The blockchain is special because it allows users to send and receive funds electronically, thereby eliminating any third-party fees. According to Angela Ruth, the blockchain can replace the middle-man and provide a “payment alternative” that can potentially protect buyers and sellers from payment scams, assuring that everyone receives what they’re rightly owed. The system provides an unbeatable form of security, as information between buyers and sellers is shared within “tamper-proof public ledgers” which ultimately make it difficult for scammers to double-spend or provide counterfeit funds.
