The generation process is as follows.
Ea&actions that are associated to their node.
Node 1 generates its own collections from its transactions but also collects transactions from Node 1b (which does not generate any collection).
Node 0 generates its own collections, and also gathers transactions from nodes 2 and 2b, which don’t. However, since the node homogeneity parameter is active, a collection is generated for each and every node.
Collection 1, issued from node 1a, as well as collections 4,5, and 6, issued from node 0, require cross validation.
