# Algorithms
|
|
|
|
Algorithm can be defined in 3 ways:
|
|
|
|
1. By pool, using algorithm negotiation, in this case no need specify algorithm on miner side.
|
|
2. Per pool `coin` option, currently only usable values for this option is `monero` and `arqma`.
|
|
3. Per pool `algo` option.
|
|
|
|
Option `coin` useful for pools without algorithm negotiation support or daemon to allow automatically switch algorithm in next hard fork.

## Migration to v3
|
|
Since version 3 mining [algorithm](#algorithm-names) should specified for each pool separately (`algo` option), earlier versions was use one global `algo` option and per pool `variant` option (this option was removed in v3). If your pool support [mining algorithm negotiation](https://github.com/xmrig/xmrig-proxy/issues/168) you may not specify this option at all.

#### Example
|
|
```json
|
|
{
|
|
"pools": [
|
|
{
|
|
"url": "...",
|
|
"algo": "cn/r",
|
|
"coin": null
|
|
...
|
|
}
|
|
],
|
|
...
|
|
}
|
