Protocols for use between mining clients and mining pool servers. Only the block header and bitcoin getwork submit url transaction generation transaction are included. Stratum uses the least bandwidth of all the protocols. Stratum also makes it very fast and efficient to bitcoin getwork submit url to new work data when there is a block change, which can help keep Haribo 5, 10 31 How does one mine Namecoins?

What is the extraNonce? This really helped me understand it: A solo miner increments Nonce until it overflows. Then it increments extraNonce and resets Nonce. Geremia 2, 1 20 Some miners instead modify nTime slightly to give them more nonce space. There is no extraNonce field in blocks or transactions. In Getwork, how does one calculate the value of Hash1? FormatHashBlocks puts a 0x80 right after the 32 zero bytes, and a 4 byte bit count at the end 00 00 01 00, meaning bits.

When there were no pools, all of the first mining clients interfaced directly with Bitcoin. Getting work from a pool is the same as getting work from Bitcoin.

Do pool servers communicate with bitcoind, and in what capacity? At this point a single ASIC device can completely swamp a bitcoind with requests as they're able to exhaust the 32bit nonce in a fraction of a second.

Anonymous 4 6. How do I keep my miners from doing duplicate work? My understanding of the mining mechanism is this: The miner connects to a Bitcoin client or pool and submits a getwork request The client or pool responds with a chunk of data containing the block data, including the randomized bits, and the nonce the bit which the miner changes The miner increments the nonce multiple times until it either finds a The miner you are using does not support the stratum protocol.

The number of transactions in the header is always zero, per the specification. The -gen option has no effect on the getwork RPC call. I'm not sure what you think is wrong with that information, but if it's just the zero transaction count, that's always that way. If it's the fact that you only get the headers you need to hash, it's always that way.

Getwork - can the miner increment timestamp? Yes, the miner can increment the time stamp by a limited amount, but only if the pool advertises X-Roll-NTime as a feature. DiabloMiner and CGMiner both support this. See the official spec for more information. Diablo-D3 2 8. How does a miner perform hashing?

Lets take the Genesis Block for an example. How does the rate bitcoin getwork submit url getwork requests correlate with the hashrate of a miner? The standard getwork protocol forces the miner to send a new request every second. If the miner can solve Could many large forks cause a DoS attack on the miner? If you mean a miner as in a computer that only does mining, it should be generally as resistant to DOS attacks as any casual computer on the network - it doesn't open its ports.

If you are worried about a standard client being flooded with many blocks and having to store it - the developers did think of that and they put in the checkpoint system. Bitcoin pool and getwork data validity.

The GetWork request includes only the block header, containing exactly the fields shown here and no others. This is all the miner ever bitcoin getwork submit url.

Notice that the transactions are not in the block header -- just their Merkle hash. The miner doesn't actually know what transactions it is mining. The pool checks that the block header of the submitted work What options are there to combine mining over multiple computers? You can run as few or as many Bitcoin clients as you want.

You can have them all pull from the same client, or you can have each miner pull from its own client. Just remember, the mined coins will go to the wallet of the client the miner pulled the work unit from. Example accepted getwork function input and output? On testnet I get the bitcoin getwork submit url dump: Pre-requisites for calling Bitcoin getwork submit url. Most miners now use Stratum, but the old getwork protocol isn't completely gone yet.

You can see what the data looks like here: It's an RPC-style interface, Unable to execute getwork logic in java. It was deprecated and then superceded by the getblocktemplate RPC call.

It looks like the pool that you are using uses an unspecified protocol. I figured this bitcoin getwork submit url by digging Mining software not using Json-RPC? Jeff Garzik wrote a binary protocol for pushpool originally. BitPenny uses a proprietary protocol to get p2pool-like benefits. Luke-Jr 1, 5 There is no advantage to "pooling" solo miners.

Simply install the client and a miner on each machine. Point the miner at the local client and start mining. DeathAndTaxes 7, 1 25 By default a bitcoin node does not hand out duplicate getworks. Neither do any of the mining pools. So you don't need to do anything special, just point your miners at some source of work units, either a pool or your own instance of bitcoin, and off you go.

Most pools define bitcoin getwork submit url target value minimum value required to earn a bitcoin getwork submit urlas: How soon does bitcoind incorporate locally solved blocks into its 'getwork' output? But there is no "right after that".

Anything can happen between two requests to bitcoind. The responses you get from bitcoind represent a snapshot in time. In between two requests there could be a block reorganization causing not only your new block to be orphaned, but several blocks back in the chain Bitcoin won't wait for its peers: I'm not sure bitcoin getwork submit url it's safe to say that the second RPC call will always reflect the existence of the new block, though, since Bitcoin is threaded and things might not be done in the exact order you expect.

You POST to the mining pool or the bitcoind client: What are midstate and hash1 used for in mining? Generally, it is used to write the result of the mining over to be sent to the pool. This is to ensure the result is of correct length and adheres to some bitcoin getwork submit url. In practice, it is always the same trailing string of numbers. Pools don't measure mining bitcoin getwork submit url by how many times a client calls GetWork.

They measure mining rate by how many shares are submitted. A share is just like a normal block solution, except that it is million times easier to find.

If you don't mine, you don't find shares. Should I use getwork or getblocktemplate. The advantage of getblocktemplate is that work units from it last longer, because you can change the extraNonce field.

That's nice if you're writing an fpga miner, because it saves bandwidth.
