ArtForz: Excellent work. I assume bitcoin does not have this vulnerability?
Well, it does have this vulnerability, but at *way* higher cost.
old SC rules:
Spamming the network with transactions, 0.0005BTC/kB vs. 0.000025SC/kB.
Filling blocks to 250kB, same fees. Beyond 250kB it gets exponentially more expensive for BTC, stays the same for SC.
current SC rules:
0.0025SC/kB.
imo way better, but still a tad low (and legit users are hitting the 4kB tx limit).
also maybe one point to consider, back when BTC was worth about as much as SC is today, the fee was 0.01BTC/kB.
Btw, some nodes crashing was probably due to running out of disk space (as it seems to have mostly affected small VPSes), as somehow 28MB of transactions in blocks produced 5GB of database commit journals. That *is* caused by a bug/lack-of-optimization in bitcoins block processing and the devs have been notified.
Also maybe worth noting: making all nodes forward, process and store those 28MB of transactions cost 0.78SC, even with the fixed rules it's 78SC... that's still only about $6. So better not piss off any bored kids with pocket change until reasonable tx limiting rules are in place.
