Smart Contract-Based Pool Hopping Attack Prevention for Blockchain Networks

Sushil Kumar Singh, Mikail Mohammed Salim, Minjeong Cho, Jeonghun Cha, Yi Pan, Jong Hyuk Park
2019 Symmetry  
To prevent pool hopping attacks, a smart contract-based pool hopping attack prevention model is proposed.  ...  Pool hopping attack is the result of miners leaving the pool when it offers fewer financial rewards and joining back when the rewards of mining yield higher rewards in blockchain networks.  ...  In Section 3, the proposed framework and methodology for smart contract-based pool hopping attack prevention is introduced for blockchain networks.  ...

On Blockchain-Enhanced Secure Data Storage and Sharing in Vehicular Edge Computing Networks

Muhammad Firdaus, Kyung-Hyune Rhee
2021 Applied Sciences  
We propose consortium blockchain and smart contracts to ensure a trustworthy environment for secure data storage and sharing in the system to address these challenges.  ...  Practical byzantine fault tolerance (PBFT) is utilized because it is suitable for consortium blockchain to audit publicly, store data sharing, and records the whole consensus process.  ...  For this reason, we propose the decentralized incentive mechanism based on blockchain and smart contracts to achieve trustworthy environments.  ...
