The iCash Proof of Trust Protocol assures the validity of smart agreement settlements. The most celebrated aspect of Distributed Ledger Technology is that information are immutably stored without the need for a central authority or intermediary. Despite this, maybe not sufficient attention are compensated towards negative impact created whenever an input to the blockchain is not trustworthy. iCash introduces the Proof of Trust (PoT) protocol as a multi-platform blockchain application that enables real-world inputs become validated by decentralized individuals in settling Smart Contracts at scale. The nature and scale of blockchain activity necessitates trustworthy inputs. While Proof of Work and Proof of Stake offer distributed trust for information storage, the introduction of PoT provides distributed trust for information input. By incorporating a trustworthy application protocol layer, real world interaction and events can become confirmed before being entered into the blockchain.
