Greedy-Mine: A Profitable Mining Attack Strategy in Bitcoin-NG. (arXiv:2306.03540v1 [cs.CR])

Bitcoin-NG is an extensible blockchain protocol based on the same trust model
as Bitcoin. It divides each epoch into one Key-Block and multiple Micro-Blocks,
effectively improving transaction processing capacity. Bitcoin-NG adopts a
special incentive mechanism (i.e., the transaction fees in each epoch are split
to the current and next leader) to maintain its security. However, there are
