Transaction hinterland

The transaction hinterland of node B as viewed from node A is the node B together with the transaction hinterland (as viewed from node B) of all B's neighbouring nodes except A which are participating in or have participated in the current transaction on a transaction branch with B. Note 1 to entry: nodes which are no longer participating in the transaction because they have signalled read-only or early-exit, continue to be part of the transaction hinterland until the transaction is terminated.
