DLT, distributed ledger technology, is the term adopted by corporations that need a version of Blockchain that doesn’t include the decentralised consensus mechanism. As the latter is the essence of Blockchain, DLT’s are no Blockchains.
Bitcoin mining is nothing else than solving an extremely difficult equation. The solution to the equation LOCKS the inputs in the equation which is the numerical representation of the content of the Blockchain database.
The Blockchain consensus system requires that transactions are audited before inserting them in the database. A bookkeeping that has Blockchain transactions as input becomes a pre-audited triple entry bookkeeping!
