CLSAG (Concise Linkable Spontaneous Anonymous Group) signature are the new
|
|
way Monero builds @ring-signatures, which replaces MLSAG (multilayered
|
|
Linkable Spontaneous Anonymous Group Signature). CLSAG will go live and
|
|
mandatory with the [Monero network upgrade of October 2020]({{ site.baseurl
|
|
}}/2020/08/18/network-upgrade-october-2020.html). CLSAG maintains the same
|
|
functionalities as MLSAG, but with the advantage of considerable size
|
|
savings for @transactions and improvements in verification speed. This new
|
|
technology was developed by contributors of the [Monero Research Lab]({{
|
|
site.baseurl }}/resources/research-lab/) and [audited by external
|
|
researchers]({{ site.baseurl_root
|
|
}}/resources/research-lab/audits/clsag.pdf).
|
|
|
|
With CLSAG, users see a 20% improvement in signature verification, and at
|
|
least a 10% overall improvement for typical transactions. For example, a
|
|
typical Monero transaction (2 inputs and 2 outputs) which usually weighs
|
|
2.5kB, takes only 1.9kB of blockchain space with CLSAG, a ~25% improvement.
