Memory pools are a collections of unconfirmed exchange as stored away by all full nodes. Memory pools fill adult in between blocks as new exchange are transmitted over a Bitcoin network and are depleted when these exchange are enclosed in blocks. But if a array of successive blocks sojourn full for an extended duration – possibly due to legitimate exchange or spam attacks – memory pools competence not exhaust completely, and backlogs could build up. With no extent limit, a reserve competence even grow to a indicate where nodes run out of memory and crash. (This is a “crash landing” unfolding former Bitcoin XT lead developer Mike Hearn feared.)
