What does schain complete=1 mean, and what is hp?
Answer
complete=1 asserts that the nodes array contains every entity in the payment chain back to the owner of the site, app, or other medium; complete=0 means the chain starts at the first known node and earlier hops are missing. Buyers commonly discount or reject inventory with incomplete chains. hp on each node indicates whether that node is in the flow of payment: when 1, the system in asi pays the seller in sid, who pays the previous node. For schain version 1.0 the spec says hp should always be 1, and intermediaries must propagate it downstream unchanged.
