Ring size refers to the total number of signers in a @ring-signature. Before
|
|
|
|
|
release [0.13.0 "Beryllium Bullet"]({{ site.baseurl
|
|
|
|
|
}}/2018/10/11/monero-0.13.0-released.html), it was possible to select an
|
|
|
|
|
arbitrary number of signers. With release 0.13, it was decided to set this
|
|
|
|
|
number to 11 to enforce transaction uniformity.

`Ring size (11) = foreign outputs (10) + your output (1)`

Foreign outputs are typically called "decoys," and the number of decoys was
|
|
|
|
|
previously called the "mixin" size.
