/** A ledger that has become irrevocable.
|
|
|
|
An accepted ledger is a ledger that has a sufficient number of
|
|
validations to convince the local server that it is irrevocable.
|
|
|
|
The existence of an accepted ledger implies all preceding ledgers
|
|
are accepted.

*/

|
/* VFALCO TODO digest this terminology clarification:
|
|
Closed and accepted refer to ledgers that have not passed the
|
|
validation threshold yet. Once they pass the threshold, they are
|
|
"Validated". Closed just means its close time has passed and no
|
|
new transactions can get in. "Accepted" means we believe it to be
|
|
the result of the a consensus process (though haven't validated
|
|
it yet).
