Also, what did you like about the results of the [Experiment] and what did you not like? (In thinking of your next coin) I had always thought CPU Only was a goal, but that seems hopeless with bots and EC2.
I think experiments are about what we learned, rather than what we liked.
1. We learned that the vote calculation code is robust. There's solid code there now for calculating the results of voting in the blockchain. If anyone has a use for proof of stake voting for any bitcoin based coin, they can simply announce a vote prefix '1MYVOTE' for example, create some voting addresses, solicit votes, and then run the code against the block chain to find out the result at a specific block number - no change to the code of the target coin required.
2. Voting does generate interest and participation - we had 80% voter participation at one point. I don't know how many people understood the concept of preferences or transferable vote but there was clearly enough understanding that people were voting for what they wanted.
3. Multiple grants requiring a low level of support don't work. This looks a bit naive to me now.
4. The single grant idea wasn't properly tested - the environment was poisonous by the time I launched it so that remains inconclusive. If MC continues we might see how that plays out.
5. Long hash times are definitely viable - that is positive for the future of YACoin type coins. There might be some stability issues to iron out with long hash times and multithreading, but they're definitely viable for a coin.
6. EC2 didn't become an issue. For a well designed CPU coin, the economics of it mean that commercial mining should not be a long term profitable venture.
7. Difficult to know if bots were an issue. From what I gathered, the largest holder was an individual who mined on three personal computers from the start.
8. For a new altcoin you can't rely on coin owners to act even in their own self-interest, let alone enlightened self-interest. There's a very low barrier to entry to be a miner. Higher barriers might be a help for a nascent coin.
