I am looking for a reliable site for downloading guiminer-scrypt v0.05 (hopefully no malware). Any suggestion would be grateful.

I downloaded from sourceforge.net, but the miner does not work with give-me-coins.com site...

Thanks.

Yes it does. You are correct that the focus would shift away from mining power to number of nodes that could overwhelm the network. I guess we all see that the key is the decentralized voting system.

Ideas are cheap. I keep seeing more and more alt-coins with different hash algorithms in the hope of defeating ASIC. I simply think they were going at it the wrong way. Instead of using a more complex/exotic hash algorithms, they should rethink how rewards are distributed. I think this is the key to negate the incentive of ASIC mining.

I am not sure it is possible to completely eliminate the Sybil attack, but I could think of many many approaches to reduce such risk in a decentralize voting system.
 

Nomination Period (N): It is a period when all nodes in the network vote for the next valid block
Wait Time (W): The time between each nomination period, this value should be auto adjusted depend on the size of transaction volume.

Features:
SHA-256
No difficulty
Super Fast verification time under light/moderate transaction volume (the dynamic adjustment of 'W' is vital to have super fast verification time)

In order to negate the power of ASIC over CPU/GPU, choosing the next valid block no longer rely on first solved block first pick strategy as most existing coins do. Instead, all participate nodes would start randomly vote for the next valid block from the largest collection of published blocks during the nomination period. All published blocks in the same collection have identical set of transactions. The rewards (500 new coins) would be evenly distributed to n number of eligible participants (randomly chosen) from the largest collection.

This concept would effectively negate the advantage of FPGA/ASIC over CPU/GPU. Every mining node would have equal opportunity to solve the next block.

What do you think?
