An RPC method used by a miner to get hashing work to try to solve. It has mostly been superceded by the newer getblocktemplate mining protocol, but the data format is still often used internal to some miner structures. It accepts one optional parameter; if provided, this must be the "data" provided by a prior request modified to meet the server's proof-of-work requirements. Because the data key has been preprocessed, if you have a bitcoin getwork response time SHA function you must first reverse the pre-processing.

This is two steps:. Note that since the result you must provide to getwork submissions is in the same format as data, you must reverse this process when you make your submission. Most miners will precompute the SHA "midstate" from the first bit chunk of data, and only repeat the 2nd SHA bitcoin getwork response time with the final bit chunk which contains the nonce.

The target is in standard SHA order big endianbut note that Bitcoin target comparisons are done as bit little endian. This means for pdifficulty 1, you want to check that the last 32 bits are zero. If that bitcoin getwork response time the difficultyyou win generated a block or share! If not, increment the Nonce that is a number stored in portion of the data that starts bits in bytes 76 to 79and try again.

If the incremented portion overflows, get new work see also rollntime extension. When getting new bitcoin getwork response time, miners should send a X-Mining-Extensions header with a space-delimited list of supported extensions:. Original specification from Deepbit. The server may include a X-Host-List header with a list of available servers formatted in JSON as an array of objects with server details.

If you use server with non-zero ttr you should try to return to the server with 0 ttr after this number of minutes. This string bitcoin getwork response time that "server.

When you detect connection problems, you need to try the next server - "backup. If the main server is still offline you should continue to use "backup. The absolute URI may specify a different port than the original connection. This request is not answered by server until it wishes to expire current block data, and new data is ready. The answer bitcoin getwork response time the same as getwork on the main connection. Upon receiving this answer, miner should drop current calculation in progress, discard its result, and start working on received data and make a new request to a long polling URI.

There is a 60 second limit before new work should be requested the normal way regardless of response from longpoll though this may be overridden by the rollntime extension below. This should be advertised if the miner supports generating its own midstates.

In this case, the pool may decide to omit the now-deprecated "midstate" and "hash1" fields in the work response. In addition to X-Mining-Extensions, the miner should also send X-Mining-Hashrate, bitcoin getwork response time an integer value of expected hashrate measured in full hashes per second. The server may then add an additional field to the JSON response, "noncerange", which contains two bit integers specifying the starting and final nonce the miner is allowed to scan.

While both values are given in big endian, miners should iterate over the range in their native bit integer type SHA works with bit integers, not character data. The miner should implement rollntime by starting from the first nonce in the range every second.

When a share is rejected, the server may include a X-Reject-Reason header indicating the reason why it was rejected. Values for this header are undefined. Iff the getwork response includes a "X-Roll-NTime" header with any value other than "N" or the null string, the miner may within reason bitcoin getwork response time the ntime field in addition to the nonce.

Also note that the headers bitcoin getwork response time a share submission should not influence the behaviour of work-- specifically, if a share submit does not have the header, it should not disable rollntime for the current work which did. Due to network latency, Luke-Jr recommends the following design for miners:. If this header is present, the Stratum-capable miner should switch to the specified URL immediately.

Theoretically pool can implement other transports bitcoin getwork response time well, although at this date Stratum miners implement only TCP transport. This feature should only be advertised with a longpoll request. If received with a regular request, it should be ignored. If supported, the server may include a "submitold" key bitcoin getwork response time the JSON result. If this key is present and true, the miner should NOT discard the result of old work default per longpoll specificationbut instead submit them to the server.

The miner should still stop working on the old work, bitcoin getwork response time begin working on the new work as soon as it can without losing the result of the old work.

The server may include a X-Switch-To header containing a single JSON object formatted in the same fashon as items in the hostlist array extension. If this header is present, the miner should switch to the specified server for at least ttr minutes after finishing current "getwork" and submitting its results.
