Distributed Ledger Layer refers to the foundational structure that records, validates, and stores data across multiple locations simultaneously. Instead of a single central database, the information is duplicated and synchronized across various nodes, making it transparent and secure.This layer enables participants to access real-time data, ensuring that all transactions are verified by multiple parties before being added to the ledger. This process helps prevent tampering and fraud, as altering the information would require consensus among a majority of nodes.Different cryptocurrencies can utilize various types of distributed ledger technologies, such as blockchain, which organizes data into blocks linked together in chronological order. Other variations may employ different structures, such as directed acyclic graphs.Overall, the Distributed Ledger Layer is crucial for maintaining integrity, trust, and security in transactions, driving the reliability of the entire network.
