Pool Examples for ETH

Pool connection definition is issued via -P argument which has this syntax:

-P scheme://user[.workername][:password]@hostname:port[/...]

values in square brackets are optional

where scheme can be any of:

  • http for getwork mode (geth)
  • stratum+tcp for plain stratum mode
  • stratum1+tcp for plain stratum eth-proxy compatible mode
  • stratum2+tcp for plain stratum NiceHash compatible mode

A note about this form of notation

This notation is called URI notation and gives us great flexibility allowing ethminer to specify all needed arguments per single connection (other miners offer single dedicated CLI arguments which are valid for all connections). An URI is formed like this

                                   Authority
            +---------------------------------------------------------------------+
  stratum://0x123456789012345678901234567890.Worker:password@eu1.ethermine.org:4444
  +------+  +----------------------------------------------+ +---------------+ +--+
      |                         |                                  |             |
      |                         |                                  |             + > Port
      |                         |                                  + ------------- > Host
      |                         + ------------------------------------------------ > User Info
      + -------------------------------------------------------------------------- > Scheme

Optionally you can append to the above notation anything which might be useful in the form of a path. Example

stratum://0x123456789012345678901234567890.Worker:password@eu1.ethermine.org:4444/something/else
                                                                                 +--------------+
                                                                                         |
                                                                    Path --------------- +

Anything you put in the Path part must be Url Encoded thus, for example, @ must be written as %40

As you may have noticed due to compatibility with pools we need to know exactly which are the delimiters for the account, the workername (if any) and the password (if any) which are respectively a dot . and a column :. Should your values contain any of the above mentioned chars or any other char which may impair the proper parsing of the URI you have two options:

  • either enclose the string in backticks (ASCII 96)
  • or URL encode the impairing chars

Say you need to provide the pool with an account name which contains a dot. At your discretion you may either write

-P stratum://`account.1234`.Worker:password@eu1.ethermine.org:4444

or

-P stratum://account%2e1234.Worker:password@eu1.ethermine.org:4444

The above samples produce the very same result.

Backticks on *nix. The backtick enclosure has a special meaning of execution thus you may need to further escape the sequence as

-P stratum://\`account.1234\`.Worker:password@eu1.ethermine.org:4444

% on Windows. The percent symbol % has a special meaning in Windows batch files thus you may need to further escape it by doubling. Following example shows %2e needs to be replaced as %%2e

-P stratum://account%%2e1234.Worker:password@eu1.ethermine.org:4444

Secure socket communications for stratum only

Ethminer supports secure socket communications (where pool implements and offers it) to avoid the risk of a man-in-the-middle attack To enable it simply replace tcp with either:

  • tls to enable secure socket communication
  • ssl or tls12 to enable secure socket communication allowing only TLS 1.2 encryption

thus your connection scheme changes to -P stratum+tls://[...] or -P stratum+tls12://[...]. Same applies for stratum1 and stratum2.

Special characters in variables

You can use the %xx (xx=hexvalue of character) to pass special values. Some examples:

Code Character
%25 %
%26 &
%2e .
%2f /
%3a :
%3f ?
%40 @

Only for version 0.16+ (older versions not affected)

Stratum autodetection has been introduced to mitigate user's duty to guess/find which stratum flavour to apply (stratum or stratum1 or stratum2). If you want to let ethminer do the tests for you simply enter scheme as stratum:// (note +tcp is missing) or stratums:// for secure socket or stratumss:// for secure socket allowing only TLS 1.2 encryption.

Common samples

Here you can find a collection of samples to connect to most commonly used ethash pools. (alphabetic order).

  • Stratum connection is always to be preferred over getwork when pool offers it due to its better network latency.
  • If possible the samples use a protocol which supports reporting of hashrate (--report-hashrate) if pool supports this.

Check for updates in the pool connection settings visiting the pool's homepage.

Variables

We tried to merge the requirements of the variables so they match all pools.

Variables Description Sample
ETH_WALLET Replace ETH_WALLET with your Ethereum wallet number including the leading 0x. 0x1234567890ABCDEF1234567890abcdef12345678
WORKERNAME WORKERNAME may only contain letters and numbers. Some pools also only allow up to a maximum of 8 characters! pl1rig01
EMAIL EMAIL may contain letters, numbers, underscores. Please encode dashes, @-sign and other uncommon charaters using the Special characters joe1.doe_jr-ny%40acme.com
USERNAME USERNAME you got from the pool (like miningpoolhub.com) my_username
WORKERPWD WORKERPWD is the password you got from the pool for the worker (like miningpoolhub.com) - if you have no password set try using 'x' my_workerpwd
BTC_WALLET As some pools honor your work in BTC (eg nicehash.com) BTC_WALLET is your Bitcoin wallet address 1A2b3C4d5e5F6g7H8I9j0kLmNoPqRstUvW
