(** The prevalidation worker is in charge of the "mempool" (a.k.a. the
|
|
set of known not-invalid-for-sure operations that are not yet
|
|
included in the blockchain).
|
|
|
|
The worker also maintains a sorted subset of the mempool that
|
|
might correspond to a valid block on top of the current head. The
|
|
"in-progress" context produced by the application of those
|
|
operations is called the (pre)validation context.
|
|
|
|
Before to include an operation into the mempool, the prevalidation
|
|
worker tries to append the operation the prevalidation context. If
|
|
the operation is (strongly) refused, it will not be added into the
|
|
mempool and then it will be ignored by the node and never
|
|
broadcasted. If the operation is only "branch_refused" or
|
|
"branch_delayed", the operation won't be appended in the
|
|
prevalidation context, but still broadcasted.
