1000 tx cost about $10 at ICO prices and $100 at IOU prices in network fees. At this moment it takes about 7 minutes to resolve 1000 tx.

That means the network will be very busy for that time, but the attack becomes very expensive after a while. After the tx are all processed, we are back to normal.


Over the next months the LISK price goes up (attack becomes more expensive) and the maximum tx per block is higher. Resulting in an even more expensive attack.



E.g. if the price goes to 50ct per LISK and the block size will be increased to 100 tx per block, 1000 tx cost $50 and take 100 seconds to resolve. That means making the Lisk network unusable for 10 hours will cost someone $18000.


100 tx per block is by far not the end. More are definitely possible. We also might introduce the use of an optional higher fee or a split of tx per block (old and new ones). There are many possibilities here.
