Distributed Sequential Consensus in Networks: Analysis of Partially Connected Blockchains with Uncertainty

Figure 4

Sequence diagram comparison between Bitcoin blockchain (a) and the sequential model proposed in this work (b) for a simple miners network (c). In (a) if site at time sends a block to , this miner will forward it to after a short verification lag . Then, will release after a much larger mining delay. In (b) however, since there is no POW, will broadcast to neighbours pretty soon at epoch .
