In fact, I also think, it would be better if SPR was CPU only coin. But it is absolutely not trivial to design algorithm, which will perform well on CPU and contrarily on GPU. In the meantime, it is really necessary to keap pace with "secret" GPU miners, to make powers equal and fair.

Heres Mine so far; (I'll update this post as I go along finding the links the pictures) This one's glow symbolises the decentralised spread of the coins.

I will send this message to everyone who posted logos in this thread. You need to submit logo (or several logos if you want) before the end of this week. You can PM me or post it in this thread with a clear statement that this is the final variant of your logo. Your logo must be 512x512 png with alpha channel. According to the rules it is also necessary to submit additional images. Almost no one makes these additional images so I will allow everyone to participate even without them but submitting them is a plus. You can also choose to use original images if your logo is using the same color scheme.

But before I do, which logo of the above 2 do you like the most? (I'm asking everyone)

well, a small change might be something that requires huge amounts of memory, or even to use diskspace in order to be calculated, which makes the use of GPU so slow that CPU are still usable for mining. (take a look at the momentum algorithm used on protoshares, miners are only 2 or 3 times faster on GPU).
Requiring to use disc space is surely not a small change. Their whitepaper seems to be outdated, when reading it the first thing I thought was that you can use bloom filter to significantly reduce memory requirements. Some googling revealed that someone else already pointed to this and other vulnerabilities in the proposed scheme were found. They seem to fixed them to some extent but its not fast to find any definite information. This all will require time, I can't just copypaste some code into SpreadCoin without understanding it. GPU miner is my priority now.

maybe stop this designer race about logo ? there were two very nice things, especially at start maybe let's point mental power to other more important things ?

Then it's vulnerable to botnets. Botnets prefer using pools/mines. SPR is quite secure from that - you need the whole blockchain downloaded and wallet started. Probably this is why currently there are no SPR botnets while SPR has a good price at the exchange. I see good future for SPR as the best CPU coin. When it will become true GPU coin I will quit ![Sad](https://bitcointalk.org/Smileys/default/sad.gif)

I don't think blockchain is a big issue for botnets.

I don't think blockchain is a big issue for botnets. Agree. But I didn't write that it's a big issue but... botnets prefer small standalone miners. So blockchain and the whole wallet is not a big issue but it some kind of issue. Other method of securing coin form botnets is when 32bit miners are much slower than 64bit miners what could depend on the coin algo. Of course it is't a big issue for botnets but again - it is some kind of issue. The same than securing car from theft - any car could be stolen but introduce many small issues (security methods/equipment) and it is much harder to steal, and sometimet even not worth it.

They seem to fixed them to some extent but its not fast to find any definite information. This all will require time, I can't just copypaste some code into SpreadCoin without understanding it. GPU miner is my priority now. Bloom filter is actually slower than the currently used solutions, since false positives are quite costly. Some people have tried it already, and using a regular hashtable and ignoring collisions is way faster (up to twice as fast depending on the implementation). But still, due to the size of the search space (2^50) and the amount of data to be hashed (2^26), even bloom filters would use an amount of memory that would not fit in the local memory of any GPU in the near future. So, even with a hashing data structure way more efficient than bloom filters (say, something twice as fast as the current implementation), we'd still have GPU and CPU mining ration bellow 5:1, which is quite acceptable. But then, momentum is not the only way to abuse the use of memory, there might be simpler ways to do so (preferably something that can be used with hashcash PoW, which makes for a much simpler transition). But then, i'm not the one deciding the priorities.
