48c28c2267 Transactions now require a hash of the last entry they've seen 
This ensures the transaction cannot be processed on a chain
that forked before that ID. It will also provide a basis for
expiration constraints. A client may want their transaction
to expire, and the generators may want to reject transactions
that have been floating in the ether for years.

79fb9c00aa Boot wait_on_signature() from accountant 
Instead, there should be a way to query for a page of log data,
and checking whether it has a signature should be done client-side.

c9e03f37ce Logger now only speaks when spoken to 
Before this change, the logger's send channel could quickly be
flooded with Tick events. Those events should only be passed to
a writer.

Also, the log_event() function no longer sends entries. That
functionality moved to the new process_events() function. This
will allow us to initialize the with the genesis block without
flooding the send channel with events the historian won't read.

Make num_hashes more intuitive
 2018-03-04 13:05:38 -07:00
Greg Fitzgerald
ff82fbf112 Make num_hashes mean the num_hashes since the last ID 
Before this change, num_hashes meant the number of hashes since
the last ID, minus any hashing done on the event data. It made
no difference for Tick events, but logged Transaction events with
one less hash than actually occurred.
