I'd rather have sidechains than 20MB++ gigablocks, and am curious where you stand ATM.
Please enlighten us all why you rather have SCs.
I'm not a huge fan of side chains yet, but Bitcoin's Grandfather (Adam Back) and a couple of other notables participating in this thread have done a lot to convince me they won't be the end of the world and may ameliorate pressure to adopt Gavin's Bloatchain proposal.
Doc's economic attack via free options still worries me, but I have faith antifragility win out in the end.
OTOH, 20MB blocks would destroy TOR, etc. compatibility and poke holes in our beautifully small (defensible/diffuse/resilient) network, which is the vehicle for BTC's antifragility.
Sorry I can't be more specific and impressively techie!
What's your take on the matter, old bean?
It isn't the 20MB block size that scares me, it is the automatic doubling every two years until we reach 20GB blocks. This scares the crap out of me because if a problem turns up we need a fork to pause the scaling. Would much rather see a series of independent increases that we take in steps.
