    55 An Efficient Proof ofWork Consensus Algorithm using Game Theory

    Technologies like Peer-to-Peer networks, cryptographic functions, and decentralization make up a blockchain which is a distributed immutable ledger used to record transactions. Blockchain-based systems lack a trusted central authority. Instead, it has a core consensus mechanism based upon which a node or a group of nodes are given authority to verify and validate the transactions. The set of nodes chosen may or may not be periodically replaced by other nodes which are based on the consensus protocol used. Nodes that participate in the consensus layer are provided with incentives to encourage the participation of other nodes. PoW(Proof-of-work) consensus mechanism is already being used in most blockchain systems. Even though the Proof-of-Work consensus mechanism imparts high security, it is still highly computational-intensive which makes it a rather negative choice for employing in any blockchain. In this study, we have proposed a Proof of Work using Game Theory (PoW-GT) consensus mechanism. In this work, we’ve used the Ethereum testbed to evaluate the performance of our proposed consensus algorithm with POW in terms of transaction time, throughput and fairness.

    Optimal growth processes in a non-stationary Gale economy with a multilane production turnpike

    The topic of the paper is relevant in the field of optimal growth theory and therefore might be seen as an intellectual underpinning for research and practice in the field of transition economies and sustainable long-time development as well. It refers to the papers Panek (2015a, 2018) devoted to asymptotic properties of optimal growth properties in the non-stationary Gale type economy with single and multi-lane turnpikes in which it was assumed that changing production technology converges in time with certain limits of technology. As far as the postulate of a non-stationary economy (here: technology change) is consistent with real processes, the hypothesis of the existence of some limiting technology may raise controversies and be difficult to verify. In the paper, referring to the above mentioned publications and Panek (2014), a Gale-type economy with changing technology, multi-lane turnpike and time-increasing production efficiency, with no assumption concerning the existence of a limit technology will be examined.
