for the Windows install and it didn't run in server mode by default meaning that many solo miners may have lost a lot of blocks. Of course there was a lot of rush to mine this new block chain but many people not realising they required to server switch and still seeing zero balance took to the mining pools despite the very low difficulty. The mining pools really made the situation much worse as all the hashing power was now centralized mainly at BTCguild.
Anyone with a direct low latency connection to BTCGuild would have easily mined a lot blocks and causing other miners blocks to be rejected or marked as stales. Many miners big and small alike found that they efforts to mine this new blockchain were futile. I call for a royal commission and thorough investigation into the I0Coin fiasco. We need to look at the block chain data and see compare time stamps. We also need to investigate the many lost blocks and coins and enumerate exactly who most of the winning blocks went to.
The pools unfortunately have to much power and are defeating the purpose of p2p currency.
That is just they way the bitcoin make files are set up, and what they build right now. Part of the issue of releasing a zero day mining block is you can't then do complete pretesting.
However, if nothing else, this has been a good demonstration of the badness of pools. In this case the pool operator launched a 51% attack, and even put about 'when you leave the i0coin ponzi scheme' . Seems a bit anti-social of them to do this to a competing blockchain, especially since they do not even believe in them. I know I for one will recommend people not to use this pool.
