4.2 Reputation Roll-up

Next, we show the layer-2 design of the anchor chain, including reputation roll-up and duplex transfer channels. Traditionally, all the historical opinions should be saved on the ledger of each MASP. Nevertheless, the explosively increasing data volume wastes considerable storage resources of MASPs. Given that opinions only serve as evidence for reputation tracing, we intend to offload them from the anchor chain and only keep the most critical bookkeeping messages. As shown in Algorithm 1, we develop layer-2 reputation roll-up, containing the following steps.

2) Reputation Compression: When reaching the threshold, RCOs take turns compressing the ...
