Agreement ledgers are distributed ledger technologies that enable users to securely store and transfer digital assets. They are based on a consensus mechanism that allows users to agree on the validity of transactions, ensuring that all participants have the same view of the ledger. Agreement ledgers are designed to be highly secure and provide a secure platform for decentralized applications (dApps) and smart contracts. They are also designed to be highly scalable, allowing for thousands of transactions to be processed per second. Agreement ledgers are an innovative approach to distributed ledger technology, offering a promising solution to the scalability and security challenges faced by existing blockchain networks.
