TLDR
Performance evaluation validates the feasibility and efficiency of the proposed game model in consensus propagation and applies the backward induction to analyze the existence and uniqueness of the Stackelberg equilibrium.Abstract:
In proof-of-stake based consortium blockchain networks, pre-selected miners compete to solve a crypto-puzzle with a successfully mining probability proportional to the amount of their stakes. When the puzzle is solved, the miners are encouraged to take part in mined block propagation for verification to win a transaction fee from the blockchain user. The mined block should be propagated over wired or wireless networks, and be verified as quickly as possible to decrease consensus propagation delay. In this letter, we study incentivizing the consensus propagation considering the tradeoff between the network delay of block propagation process and offered transaction fee from the blockchain user. A Stackelberg game is then formulated to jointly maximize utility of the blockchain user and individual profit of the miners. The blockchain user acting as the leader sets the transaction fee for block verification. The miners acting as the followers decide on the number of recruited verifiers over wired or wireless networks. We apply the backward induction to analyze the existence and uniqueness of the Stackelberg equilibrium. Performance evaluation validates the feasibility and efficiency of the proposed game model in consensus propagation.read more

Incentive Mechanism for Reliable Federated Learning: A Joint Optimization Approach to Combining Reputation and Contract Theory
TL;DR: This article introduces reputation as the metric to measure the reliability and trustworthiness of the mobile devices, then designs a reputation-based worker selection scheme for reliable federated learning by using a multiweight subjective logic model and leverages the blockchain to achieve secure reputation management for workers with nonrepudiation and tamper-resistance properties.

Toward Secure Blockchain-Enabled Internet of Vehicles: Optimizing Consensus Management Using Reputation and Contract Theory
TL;DR: Li et al. as discussed by the authors proposed a two-stage soft security enhancement solution: miner selection and block verification, which evaluates candidates' reputation using both past interactions and recommended opinions from other vehicles The candidates with high reputation are selected to be active miners and standby miners in order to prevent internal collusion among active miners.

Information propagation in the Bitcoin network
TL;DR: This paper analyzes how Bitcoin uses a multi-hop broadcast to propagate transactions and blocks through the network to update the ledger replicas, and verifies the conjecture that the propagation delay in the network is the primary cause for blockchain forks.
