A method and a DL node for processing a transaction in a distributed ledger (DL) network based on policies are described. A request for a transaction including data is received at a DL node from a user device. A first set of one or more DL nodes of the DL network that have characteristics that satisfy one or more policies associated with the data of the transaction are determined. In response to determining that the DL node is one of the set of DL nodes, the transaction is executed at the DL node, and the transaction is inserted as a private transaction in a digital ledger of the DL network causing a second set of one or more DL nodes of the DL network that is different from the first set of DL nodes to access only an identifier of the transaction and not a payload of the transaction.

Policy-aware distributed ledger networks

A delay unit is provided to delay adapting modes of a codec if channel communication conditions are improving. A less robust mode having a higher intrinsic quality is selected only after some delay. The quality of the communication is measured to give quality values for successive measurement occasions. The delay unit comprises a plurality of memory cells in a memory for storing the quality values of the communication conditions of the channel for the most recent measurement occasions. A selector operates according to an algorithm for selecting one of the memory cells. The content of the selected cell is used to set the mode of the codec.
