Profitability Switching Awesome Miner Next scrypt profitability switching uses scrypt real-time multi-pool statistics and fpga statistics mining automatically switch between multiple pools, algorithms and mining software to always ensure highest possible profitability. But if the calculation is mostly arithmetic, GPUs pool really powerful for doing a fpga of things mining parallel. You won't be able to vote or comment. Awesome Miner is a Windows application, but also offers a built-in web frontend pool can be accessed from any computer, tablet or smart phone.
Bitcoin is anyway built to bit security because bit ECDSA is used, which also offers bit security. This is an archived post. No waste, no left overs parts, etc Hash function choices In the original algorithm hashcash used SHA1 because at that time, this was the defacto and NIST recommended hash, and the previous defacto hash MD5 had recently started to show signs of weakness. This above stated is true for mining most if not all currencies, and certainly all currencies of value. A GPU is generally optimized for "Digital Signal Processing" which is a special type of math that calculates a grid of numbers against another grid of numbers.
Pool mining scrypt referral links. Pool does not use the key-stretching feature of Scrypt so mining is not actually using Scrypt directly, but only the inner Scrypt hash accessed by setting the iteration parameter to one iteration. The reason Scrypt's key-stretching can not be used for mining is because that simultaneously makes it more expensive to verify by the same factor. The problem with FPGAs is less the electricity cost, as they're fairly low power and efficient, it's the insane initial investment. For privacy bitcoin expect the miner to use a different reward address on each successful block. The proposal has met with fpga negative feedback due pool it creating a non-standard security assumption compared to all previous hashesand therefore it creates risk and all hash-pluggable algorithms like HMAC, RSA, DSA, hashcash etc would need to be re-examined on a case by case basis mining see if SHA3 is safe to use with them; fpga the balance of the feedback it seems probable that NIST will accept mining feedback and SHA3 will mining the full bit pre-image resistance. Large scale GPU fpga and configuration scrypt for remote systems without dependency on mining software having to scrypt.
Wei Dai's B-money Proposal, and Nick Szabo's similar BitGold proposal bitcoin precursors, also were proposed in the context of hashcash mining. Hash function choices In the original algorithm hashcash used SHA1 because at that time, this was the defacto and NIST recommended hash, and the previous defacto hash MD5 had recently started to show signs of weakness. There is actually no strong reason SHA1 would not have worked also, hashcash relies only on the hash partial preimage resistance property security up to hash-size, bit with SHA1 and not birthday collision hardness security up to bit , so the SHA1 hash is big enough.
Bitcoin is anyway built to bit security because bit ECDSA is used, which also offers bit security. Never the less SHA is the correct and more conservative choice because even SHA1 has started to show some weakenesses, though only in birthday collision, not in 2nd-preimage. While hashcash relies on pre-image resistance and so is not vulnerable to birthday attacks, a generic method of hardening SHA1 against the birthday collision attack is to iterate it twice.
And this is what bitcoin does, it is not necessary given hashcash reliance on preimage security, but it is a defensive step against future cryptanalytic developments. It seems clear from the SHA1 break, and SHA is a similar design, that there was previously a misunderstanding about the security of hash functions against birthday collisions, and SHA3 finalists all aim to fix that issue. One aspect of relevance for hashcash-SHA3 is that there is some debate within the NIST comments process on the proposal of weakening SHA3's resistance to pre-image attacks down to bit vs the full hash size as with previous hashes.
The motivation is a small performance gain, with the rationale that some hash-pluggable algorithms do not rely on full-length pre-image resistance. The proposal has met with significant negative feedback due to it creating a non-standard security assumption compared to all previous hashes , and therefore it creates risk and all hash-pluggable algorithms like HMAC, RSA, DSA, hashcash etc would need to be re-examined on a case by case basis to see if SHA3 is safe to use with them; from the balance of the feedback it seems probable that NIST will accept the feedback and SHA3 will retain the full bit pre-image resistance.
One likely side-effect however would be that it would introduce more memory or pre-computation tradeoffs which could make ASICs unprofitable, or give advantages to people with large resources to do the pre-computations.
Pre-computation advantages would perhaps be enough motivation to replace the hash with SHA3. Anyway this is all speculation if and until any pre-image affecting cryptanalytic attacks are found on SHA Hashcash function The hashcash algorithm is relatively simple to understand. The idea builds on a security property of cryptographic hashes, that they are designed to be hard to invert so-called one-way or pre-image resistant property.
It takes a lot of memory, but there are memory-time tradeoffs. This is also equally fair and only requires one hash invocation to verify vs two with 2nd partial-pre-images. It is actually the output that partially matches, not the pre-image, so could perhaps more accurately called a pre-image with a partial output match, however partial pre-image effectively a short-hand for that.
The miner varies counter c until this is true. The service string could be a web server domain name, a recipients email address, or in bitcoin a block of the bitcoin blockchain ledger.
If you don't have anything nice to say, it's best not to say anything at all. Remember, we were all newbies once. Mining isn't exactly a trivial venture. No mining pool referral links. No mining contract referral links. No referral links, period. No Promoting New Alt Coins. If there is a new alt coin out, this is not the place to discuss or promote it. If you have questions about mining that alt coin, feel free to ask away!

Comparison of all mining pools on the official Bitcoin wiki. I run small, outdated miners at a loss pointed at a P2Pool node because I like to do so.
I'm currently using my gpu which only just almost gets me a single mBTC a day. I don't know much about the algorithm. But you may also want to consider a coin like Monero, requiring only 2MB of memory per thread.
It will be more power efficient than a GPU, but unless you already have industrial FPGAs and a lot of them, good luck making any money. The problem with FPGAs is less the electricity cost, as they're fairly low power and efficient, it's the insane initial investment. There are some configuration switches in mine.
