+interface-record
+==================
+
+A libp2p node needs to store data in a public location (e.g. a DHT), or rely on potentially untrustworthy intermediaries to relay information. Libp2p provides an all-purpose data container called **envelope**, which includes a signature of the data, so that it its authenticity can be verified.
+
+The record represents the data that will be stored inside the **envelope** when distributing records across the network. The `interface-record` aims to guarantee that any type of record created is compliant with the libp2p **envelope**.
+
+Taking into account that a record might be used in different contexts, an **envelope** signature made for a specific purpose **must not** be considered valid for a different purpose. Accordingly, each record has a short and descriptive string representing the record use case, known as **domain**. The data to be signed will be prepended with the domain string, in order to create a domain signature.
+
+A record can also contain a Buffer codec (ideally registered as a [multicodec](https://github.com/multiformats/multicodec)). This codec will prefix the record data in the **envelope** , so that it can be deserialized deterministically.
+
+## Usage
+
+```js
+const tests = require('libp2p-interfaces/src/record/tests')
+describe('your record', () => {
+  tests({
+    async setup () {
+      return YourRecord
+    },
+    async teardown () {
+      // cleanup resources created by setup()
+    }
+  })
+})
+```
+
+## Create Record
+
+```js
+const multicodec = require('multicodec')
+const Record = require('libp2p-interfaces/src/record')
+// const Protobuf = require('./record.proto')
+
+const ENVELOPE_DOMAIN_PEER_RECORD = 'libp2p-peer-record'
+const ENVELOPE_PAYLOAD_TYPE_PEER_RECORD = Buffer.from('0301', 'hex')
+
+class PeerRecord extends Record {

+    // Implement and return using Protobuf
+  }
+
+  equals (other) {
+    // Verify
+  }
+}
+```
+
+## API
+
+### marshal
+
+- `record.marshal()`
+
+Marshal a record to be used in a libp2p envelope.
+
+**Returns**
+
+It returns a `Protobuf` containing the record data.
+
+### equals
+

+
+Verifies if the other Record is identical to this one.
+
+**Parameters**
