## AI overview

This article explains Matter's Distributed Compliance Ledger (DCL), a cryptographically secure distributed storage network based on blockchain technology. It describes the device, vendor, software-version, compliance, and attestation information stored in DCL and how Matter ecosystems can retrieve and use it.

## Source excerpt

As Matter promised, Device Manufacturers (Vendors) don't have to build their own Phone APP or Cloud service if they don't want to. A Matter device will be able to work with all Matter enabled ecosystems seamlessly. But how could the Matter device's information be published, so that it can be retrieved by Matter ecosystems, in a secure manner? Today, we will talk about the Distributed Compliance Ledger (DCL) in Matter.
