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

Figure 2

Two ways for error propagation in the miners consensus network: to a nonneighboring node (a) and to the next block solver (b). The tables summarise the blockchain dynamics in a cycle. Rows represent sites and columns represent iterations. In the first case, the error (represented as ) cannot be restored and it persists in the blockchain. In the second case, an additional recovery step can restore the error to the agreed value of .
