The ETSI White Paper introduces a layered reference architecture for Permissioned Distributed Ledger (PDL) systems, which prioritize privacy, energy efficiency, and higher transaction speeds over permissionless alternatives. This framework supports the integration of PDL with various technologies through smart contracts that ensure integrity throughout their lifecycle, enabling applications in mobile networks, data sharing, and artificial intelligence. The document also highlights emerging advanced distributed ledger technologies, such as redactable ledgers and payment channel networks, to further enhance network performance while noting new challenges for future standardization.
