On energy efficiency, actually using more energy with PoW may lead to greater energy efficiency for the world:
https://bitcointalksearch.org/topic/m.3090924
Also Adam Beck pointed out in a post which I've lost the link to, that if botnets are used to mine PoW, that has positive effects in the sense they can't be used to do more malicious activity (and also note this high use of CPU and DRAM is likely to the cause the owner of the botnet slave computer to notice their computer resources are being remote controlled). Note my design for an Scrypt-like PoW eliminates computers without significant DRAM.

Chaum's group signature repudiation ****
Vote.
GPU, ASIC and botnet resistant coin with zerocoin anonymity features.
Please don't vote based on a misunderstanding of what is technically possible or not. I have listed features above which I am sure can be implemented.
Note I have not included features which I think can be gamed or are niche-markets, e.g. MemoryCoin's grants. I think this would just encourage all those supporters to come spam the vote here and skew the ranking. I am interested to compare the mainstream coin features.
I am not including UI features here, as that can be third-party work that doesn't have to be in the coin protocol.
If I have missed an important feature, please list it here in this thread, and I will add it to the poll if this forum allows it. Otherwise, I will collect these and rerun the poll later.
Note I thoroughly debunked the Bitcoin2 proposal.
Feel free to discuss any new features in this thread.
* Faster confirmation times don't add insurance (probability) against abandoned forks
** Inflation is necessary for an economy to grow. New coins fund the mining ecosystem to maximize protection against 50+% attack.
*** I don't believe non-PoW schemes are secure.
**** becoming irrepudiable after N blocks, necessary to support transactions that can fail to deliver
***** So upcoming of a sudden powerful miner doesn't take a HUGE advantage mining too many coins. Actually it is more than that:

Difficulty retarget
We will keep the retarget block the same as Bitcoin's 2016, but because blocks are found 4 times faster, difficulty will retarget about every 3.5 days. The combination of fast retarget times and Scrypt proof of work (Litecoin will not compete with Bitcoin for miners) means we expect to not see the sort of problem Namecoin encountered; hashing power that leaves more suddenly than it came, causing a high difficulty slog for everyone who stayed.
