Abstract
Embodiments of the disclosure provide an endorsed value in a permissioned ledger in a DDBMS. The permissioned ledger includes entries, each comprising a key and at least one value. Permission is required for a peer node to access the ledger. Digital transactions may only be appended to the ledger. Each peer node maintains at least a portion of a replica of the ledger. A request for valuation of an object is received. A candidate object value of the object is obtained. An endorsed object value of the object is obtained based upon a consensus protocol among peer nodes in the network. A data block is added to the ledger including the endorsed object value, where the added data block is cryptographically linked to a previous data block.
