Cross-Consensus Measurement of Individual-level Decentralization in Blockchains. (arXiv:2306.05788v1 [cs.CR])
cs.CR updates on arXiv.org arxiv.org
Decentralization is widely recognized as a crucial characteristic of
blockchains that enables them to resist malicious attacks such as the 51%
attack and the takeover attack. Prior research has primarily examined
decentralization in blockchains employing the same consensus protocol or at the
level of block producers. This paper presents the first individual-level
measurement study comparing the decentralization of blockchains employing
different consensus protocols. To facilitate cross-consensus evaluation, we
present a two-level comparison framework and a new metric. We apply the …
