Looking for nonces of even numbers

Each one of bitcoin and its derived crypto-currencies has a nonce value in the block, no matter what the algorithm is. Every miner tries to search for a luck nonce which can make the hash value smaller than the target under the required…

What features of scrypt() make Tenebrix GPU-resistant?

There's a fork of Bitcoin called Tenebrix that is claiming to be CPU-friendly and GPU-resistant (with regard to mining). They say that this is because they're using scrypt instead of SHA256. From what I'm reading, scrypt seems similar to bcrypt or…

How does the CPU hashing algorithm used in Yacoin differ from scrypt?

Alt-coins are now a dime a dozen and with only minor changes to generation rates, difficulty, and algorithms, they all tend to use the SHA-256 (bitcoin) or the scrypt (litecoin/tenebrix) hashing algorithms for solving blocks. A friend of mine…

Litecoin - Is better use a good CPU or good GPU?

I heard in some forums that mining Litecoin is better using a good CPU (Processor), different from Bitcoin that's better mine using a good GPU (Videoboard). I want know, this is true? For litecoin, is better buy some good processor like i7 instead…

Full example data for scrypt Stratum-client

I'm trying to write a Mining client for Scrypt-based mining using Stratum Communication. As of now, I have some trouble verifying all my bit orders and sequences. Hashes I'm generating get always rejected due to not meeting the Target. What I'm…

How does scrypt pow work?

Bitcoin's pow is sha256, the hash of header is taken and check against a given target to see whether it is smaller than the target, this can be easy seen as block hash starts with zeros. But how does litecoin's scrypt works, from the block explorer,…

Why did Litecoin choose the scrypt factors that they did?

Litecoin uses the scrypt factors (N=1024, r=1, p=1) This means that each hashing thread takes 128kB of memory. The scrypt paper recommends r=8. Colin Percival, the creator of scrypt, has said: Q: are you into #litecoin at all? A: I'm aware of it,…

Does CPU mining become efficient as memory requirements increase?

I am focusing on an anti scrypt coin called Vertcoin which increases it's N-factor at a set interval. On their main page on bitcointalk it states that CPU computation will make gains as N-factor (memory requirements) increase. Can anyone explain as…

Litecoin mining 10 times slower than a couple of days ago

I have a 5850, and have been mining with it for about a week. With GuiMiner I can mine bitcoins at about 275Mhash/s. This has not changed. A couple of days ago I setup Litecoin mining and it was working at about 350Khash/s, which at the time was…

Is equihash/scrypt suitable for pooled mining?

A "sequential memory-hard" PoW scheme cannot be parallelized effectively thus I imagine you also can't distribute solving the puzzle between participants in a pool? How does that work with scrypt then - for instance how do litecoin mining pools…

Is Vertcoin really ASIC resistant?

Vertcoin comes with Adaptive-N-factor, which means the scrypt algorithm PBKDF parameter N will be changed according to the announced time table. Litecoin has N=10, while Vertcoin starts with N=11. And they claim the adaptive-N will resist the ASIC…

Why GPU (cgminer) scrypt mining generates so many false-positive nonces?

I understand that GPU might have less accurate results of real numbers because speed/performance is the target. But I don't understand why it also occurred in integer numbers. Taking mining algorithm, scrypt hashing, for example, there are almost…

how does Scrypt use memory?

I saw in some places that Scrypt uses a lot of memory, therefore a good supply of system RAM is needed to hash with it. however, I saw in other places stating that is ONLY uses L2 Memory. which one does it use?

How to setup a DNS Seeds node and a Seed Node (for Litecoin clone)

I'm doing this for study purposes (creating a Litecoin clone). I read somewhere that for SCRYPT clones, the DNS Seeds nodes aren't necessary? If I do need them, how to I setup these nodes. I know a DNS Seed node contains a list of IPs that are…
