Description: A reputation ledger is a record of users’ reputation scores and activities in a decentralized network. This concept is based on the idea that trust and reputation are fundamental for online interactions, especially in environments where there is no central authority to validate users’ actions. Through a reputation ledger, each user can accumulate a score that reflects their behavior, contributions, and the perception others have of them. This record is immutable and transparent, meaning that all participants in the network can access and verify the information, thus promoting accountability and integrity. The main features of a reputation ledger include its decentralization, the ability to be audited by any user, and resistance to manipulation, making it a valuable tool for fostering trust in exchange platforms, social networks, and digital markets. In a world where online interactions are becoming increasingly common, the reputation ledger emerges as an innovative solution to address the challenges of trust and accuracy in digital relationships.
