Commitment hinterland

A node's current commitment hinterland is the set of nodes in the transaction tree which include: a) the neighbouring nodes from which ready signals have been received; and b) the commitment hinterlands of those neighbouring nodes, and so on recursively. NOTE — the commitment hinterland excludes those nodes which signal read-only or one-phase or earlyexit. NOTE — with the static two-phase commitment procedures and no use of either read-only or one-phase commitment or early-exit, the commitment hinterland of a node will be identical to the transaction subtree of the node.
