Multi-access edge computing node with distributed ledger

A dedicated processor for installation at a multi-access edge computing node located within a cellular coverage area supported by a base station of a mobile network operator, the dedicated processor having electronics divided into logic partitions comprising

• a ledger management partition configured to share computational load of a stock processor of the multi-access edge computing node to include a new data block, to record a current transaction in respect of a good or service, into a chained data block stored in at least one memory of the multi-access edge computing node on which the dedicated processor is installed, in response to a signature, generated from processing the data of the current transaction with coded data of past transactions stored in the chained data block, being validated by a group of external multi-access edge computing nodes which are trusted;
• and
• a shielded transaction validation partition configured to:
• produce shielded data comprising data of the current transaction determined to require shielding;
• and
• formulate statements designed to prove a truth about whether content of the shielded data is known, with the shielded data being masked.
