API Reference JSON RPC - Bitcoin-Ultimatum-BTCU/btcu-wallet Wiki

Multi-pool, multi-worker proxy for Bitcoin miners, supporting long polling and pool failover. These settings must be set for the proxy to function correctly. In this case, make sure that the settings are properly changed either in your php. PostgreSQL may be supported in a future release. Just point your web root at the htdocs folder and everything should be all set. The included. Note that while you can install to a subdirectory, some miners do not support this!

These miners only accept a host and port, but not a path. You will have to use htdocs as the web root in order for these miners to work. Navigate your browser to the admin directory inside the htdocs folder. The first thing you will want to do is add all the pools you will be using. Click the "pools" link and then the "new pool" button. Enter a name for the pool this is for display purposes only and the pool's URL.

Do not enter login credentials as part of the URL; pool credentials are managed elsewhere. Check the enabled checkbox and save the pool. Repeat this for all the other pools you will be using. Now set up some worker accounts. You should use a different worker account for each instance of mining software you are running.

This will allow you to remotely administrate their pool assignments separately, as well as determine which miners are not operating correctly. If you used one account for several workers, they would be treated as one distinct miner by the proxy and information about them will be aggregated, and usually you don't want that.

Once you have all your worker accounts set up, you need to associate workers with the pools you want them to work on. Click the "manage pools" button next to a worker.

You will see a list of all your pools; each will have a "create pool assignment" button. After clicking it, you will be asked for details about the assignment:. You do not have to assign each worker to every pool if you don't want to. Unassigned pools will simply be ignored. At this point you should be able to point your workers at the proxy and they will start working.

You can verify this by watching the "Worker status" section on the dashboard. In the pool list you will see a red or green flag for each pool indicating whether it is enabled. You can click the flag to quickly toggle the status of the pool.

This will globally disable the pool for all workers. Disabled pools will have a red background. In the pool assignment list for specific workers, there are two flags; one for the pool and one for the specific assignment. You can click the flag for the assignment to quickly toggle the assignment on or off.

This will affect only the worker you are managing. You cannot click the pool's flag. This is to prevent a pool from being accidentally disabled globally. Rows with a red background indicate that the worker will not request work from this pool -- in other words, if either the pool or the assignment are disabled. Note that disabling a pool or assignment will not prevent any shares from being submitted if the worker is currently working that pool.

It will affect new work requests only. So you can safely disable a pool while your miners are running and they will finish their current work, switching over to the next pool in the list on their next getwork request. It will rewrite any long polling URL received from a pool so that the long polling request passes through the proxy.

There is one caveat: if the pool is disabled while a worker has an outstanding long poll request, it may not notice this, depending on the logic in the client! This means that the client will effectively be working without long polling against its new pool until its outstanding request returns. At that point it may begin working on the work returned in the long poll request, which will be for the disabled pool!

This is ok; the work submissions will be correctly routed back to the now-disabled pool. This problem may be fixed in a future release by having the long-polling code check the database every few seconds to make sure that the pool and assignment it is proxying for are still enabled, returning early with an error code if it finds either to be disabled. You should not have to do very much to maintain the database, but you may need to delete some data occasionally.

Depending on how many miners you are running and what their request rate is, you may need to clean out this table as often as once a week. You can use the following query to do so:. Note that this will cause some stats to disappear; for example, if one of your workers has not been operating since midnight UTC, it will show as never having requested work on the dashboard. Do not simply truncate the table; if you do this while your miners are working, the proxy will be unable to route share submissions back to their correct pool.

You may truncate this table if you wish since the miners do not depend on it to request work. It is an informational table only. However, keeping a week or two's worth of data around is a good idea in case you need to report a statistical discrepancy to a pool operator. It's always good to have logs. The proxy may at some point be able to purge old data periodically by itself.

In the meantime, you will have to do so manually. Failure to do this might result in errant behavior. You may additionally need to upgrade the database schema. This script will apply any schema changes to your existing database safely. When run against a database with the latest version of the schema, it will do nothing. Source forum post.

If a work submission fails due to an HTTP or JSON-level error this is different from the share being rejected , the software should try again a few times and then finally disable the pool for a few minutes to prevent miners from working a pool that cannot process share submissions.

Hey boss! Host: Webserver IP, port 80? I tried several programs, but the answer: Server not found, or Nothing to read from server after xtime sleeping 1 seconds inbetween. When a pool fails to respond to a request or returns an error, the software should only try again on the next few requests and then back off for a minute or two to improve efficiency of the miner as well as give the pool some breathing room. Some pools take longer than 2 seconds to respond to submission requests depending on load, ddos, etc This isn't a problem during a getwork request just hop to the second pool in line , but it has been causing a high number of "rejects" for me.

I propose implementing a submission caching system. The proxy caches the submission allowing the worker to immediately request a new piece of work. Many pools provide an API to view the balance of your account. Perhaps this can be integrated so you can view the balance of all of your pools from the pool overview page.

The proxy should be modified to support Deepbit's failover extensions. This will require database schema changes to cache the contents of the X-Host-List header, as well as code changes to support failing over to the hosts. Don't know if this would be really usable. I can see if you want multiple workers on the proxy to point to one worker on the pool. Does that defeat the point of this proxy? Not sure what the issue here is, if someone can point me in the direction to debug this I'll happily do it.

The pool works fine with a direct connection from phoenix, but doesn't get used at all via proxy. I've double checked pool info in the proxy DB and it is correct. Perhaps related to the multipool issue? While it reports the other 7 as down completely. I've been running the proxy for about 4 hours now. My setup is Phoenix 1. I've managed to install and configure the proxy adding pools, workers, and adding workers to pools , but when I point a miner to it, it seems that only the authentication happens.

Here's what phoenix spits out:. I'm not sure if this should work, however. Right now you can edit the pools assigned to a worker, through the worker. You choose the pool, and then add workers into it, etc. If the pool or pool-worker assignment corresponding to an outstanding long polling request is disabled, the long polling request does not abort.

This has three implications:. Rather than change individual priorities by click, edit and save, wouldn't it be much easier to just drag and drop to rearrange the position on the list? From the creator of DiabloMiner: "The proxy probably does not correctly support things DiabloMiner does, such as time incrementing and returning multiple nonces for the same getwork over short periods. It looks like the sendwork thread is being choked by the proxy. After typing the username and password like defined in config.

I can do this a infinity time without ever getting into the site. Everything appears to be set up correctly - Pools added and active, workers added and active.

You need to set up payment btc (the problem of sending a json post)?

Cryptocurrencies have become been a favourite monetary tool of cyber criminals, as their lack of centralised authority or control provides a level of anonymity not available with other means of currency exchange. One of the first practical transactional uses for cryptocurrencies was popularised on illegal darknet black markets, such as the now infamous Silk Road. The increasing popularity of cryptocurrencies as a speculative investment has led to an increase in cryptocurrency-based cybercrimes. The much-publicised thefts of Japanese based exchanges Coincheck and MtGox prove that cryptocurrency theft can be highly lucrative.
