"CTOR is a brilliant innovation and excludes an enormous amount of useless information that need not slow block propagation and processing and will allow Bitcoin BCH to scale to global
levels. And CTOR is perfectly consistent with the Whitepaper:"...we need a system for participants to agree on a single history of the order in which they(transactions) were received"
However, this refers to double-spend arrival ordering. The mere presence of a transaction in a block signals that it was seen first and its "order" established.
