I've been trying to quickly catch up with the details of Knots. Is this true: - it's new, and hasn't been reviewed much - it limits op_return to 42 bytes - today, Core has a limit of 80 bytes - but the next release of Core will have no limit on op-return - both clients transfer data via the normal Bitcoin client relay network and not over any other network; i.e. neither of them use any other network I'm trying to write neutrally, to get the facts straight. I'm very aware of the spam/op-return/unspendable-utxo debate, I just don't know much about Knots specifically
