Abstract

The blockchain is a distribuited system used for registration of financial transactions and other sensitive information, following a specific consensus mechanism to ensure its security. Currently, Proof-of-Work is the most used consensus, but it has limitations related to the efficiency and electric power consumption, raising interest on other mechanisms, as Proof-of-Stake. Our research group has proposed previously a new Proof-of-Stake consensus that does not require validating committees, being more efficient than other consensus. The purpose of this paper it to propose new methods to evaluate the new consensus mechanism in real scenarios, considering a heavy creation and dissemination of transactions among all nodes. The evaluation also considers the creation and transmission of blocks completely full of transactions, making the network activity more intense and closer to that of an application under severe workloads.
