Proof of Virtue: Nonce-Free Hash Generation in Blockchain
Published in N. Jeyanthi, Kun Ma, Thinagaran Perumal, R. Thandeeswaran, Managing Security Services in Heterogenous Networks, 2020
A Nakamoto consensus can be defined as a probabilistic approach that is nondeterministic in nature. In this model every node need not agree on the same value; instead, they agree on the probability of the value being correct. This consensus mechanism is proved to have the following characteristics through its famous implementation Bitcoin:Byzantine fault tolerance – There is no leader election in this process; instead, the decision is dependent on the nodes solving the computational puzzle faster and getting a chance to propose its value.Incentive mechanism – When a node solves the puzzle and proposes a value agreed to by other nodes, an economic incentive is rewarded to the winner node.Sybil resistance – Rather than using the conventional PKI authentication scheme or any other scheme, a proof of work (POW) mechanism is involved in the consensus process, making sure the process is Sybil resistant.Gossip protocol – The peer-to-peer gossip protocol ensures messages are routed to all the nodes in the asynchronous network, assuming each node is connected to a subsection of nodes only.

The HashGraph technology uses an algorithm known as gossip protocol (Alan Demers, 1987). A gossip protocol works the same way a broadcast happens in the network. A gossip protocol spreads the information in the network. A node possessing the information shares the information with all other nodes present in the network. The process continues until all the nodes get the information and thus synchronize the whole network with this information.

In order to guarantee consistency in the data of logistics company nodes, based on the Gossip protocol, each node in the blockchain network periodically broadcasts a message to indicate that it is alive and successfully connected to the network. Each node maintains a list of all nodes in the network, which records whether all nodes are alive or dead.
