This addresses incentive alignment in blockchain consensus for participants, but appears incremental as it modifies existing proof-of-work or proof-of-stake paradigms without broad validation.
The paper tackles the problem of block creation in blockchain systems by proposing a proof-of-spending mechanism, where a node's probability to create a legal block is proportional to its historical coin spending, aiming to alter incentive structures without specifying concrete numerical results.
We introduce proof of spending in a block-chain system. In this system the probability for a node to create a legal block is proportional to the total amount of coins it has spent in history.
