I'll be looking at ways to solve [51% attack] going forward, even though I think the current situation will resolve itself soon.
1. Merged mining.
2. Merged mining.
3. Alert user if nethash drops by c. 50%... oops! this happened already. See #1.
4. Merged mining.
5. Tighten timestamp accuracy requirement. Make miners run ntpd.
6. Design a new getwork/pool protocol that gives clients/members control of policy.
7. Alert user if a reorg with many hidden or old blocks occurs.
Pardon me if SC already does any of these.
All merged mining would do is skyrocket solidcoin difficulty above bitcoin difficulty, except taking a long, long time to do so. An increase of supply of that size will also drop sc price below ixcoin or even i0coin price! I do not support merged mining for any cryptocurrency - it simply doubles the chance of disaster.
