SysCoin isn't really a market favourite.
Unlike vertcoin.
However, while Vrn can continue to mine invalid v4 blocks, we can't do a lot.
If we can generate a CSV transaction with a locktime for an output TXID, and get Vrn to mine a block that spends that transaction before it should be spendable, we should be able to get it to fork away, I think?
Anyone capable of doing this or saying that this is nonsense?
