Abstract

Bitcoin, well-known cryptocurrency, selected Poof-of-Work (PoW) for its security. PoW mechanism incentivizes participants and deters attacks on the network. So far, Bitcoin's PoW has been adopted in many cryptocurrencies. Researchers found, however, some vulnerabilities in PoW such as selfish mining, block withholding attack, and so on. Especially, after Rosenfeld suggested block withholding attack and Eyal made this attack practical, many variants and countermeasures have been proposed. However, most of countermeasures cause many changes in the mining algorithm itself, which makes it impractical. In this paper, we propose new countermeasure to prevent block withholding attack effectively. Mining pools can adapt our method without changing their mining environment.
