摘要
Cryptocurrencies have recently gained huge popularity. It is desirable to come up with effective approaches to constructing better blockchain protocols. In this paper, inspired by the 2-hop design by Duong et al (ePrint 2016/716), we put forth a generic paradigm for blockchain design, called n-hop blockchain. It includes one main chain, which is supported by (n - 1) supporting chains; hence, the main chain can achieve better security performance. In our paradigm, we show that our n-hop design can be easily extended to (n + 1)-hop design. To demonstrate the power of our paradigm, we showcase two instantiations: 2-hop blockchain variant, a combination of proof-of-stake and proof-of-work, and 3-hop blockchain variant, which is extended from 2-hop blockchain variant by adding Byzantine fault tolerance blockchain in 3rd hop.
