Thus, there is no centralized recordkeeper with authority over the ledger. This is where blockchains achieve their resistance to corruption: anyone hoping to tamper with the ledger will need to suborn a significant fraction of participants, not just one.
It's interesting how there isn't a recordkeeper, as a blockchain is known to organize chunks of records. With that amount of data, someone needs to maintain it. To be honest, I think that's what creates the ambiguity due to the fact that there is no recordkeeper to draw the line between certain construed ideas.
