Hi Nick,

Could you explain what you mean by "consistent"?

As for monotonically increasing, does the following language in Rob's
PR match what you mean?

"These STHs SHALL be ordered chronologically by timestamp, oldest
first, beginning with the earliest STH in the specified range."

The gossip draft defines an STH pollination mechanism that monitors can
use to exchange STHs that they observe.  Would this work, or were you
thinking about something else?

Regards,
Andrew
