+# Milestone Delivery :mailbox:
+
+**The [invoice form :pencil:](https://docs.google.com/forms/d/e/1FAIpQLSfmNYaoCgrxyhzgoKQ0ynQvnNRoTmgApz9NrMp-hd8mhIiO0A/viewform) has been filled out correctly for this milestone and the delivery is according to the official [milestone delivery guidelines](https://github.com/w3f/Grants-Program/blob/master/docs/milestone-deliverables-guidelines.md).**
+
+* **Application Document:** [Nolik](https://github.com/w3f/Grants-Program/blob/master/applications/Nolik.md)
+* **Milestone Number:** 2
+
+**Context**
+
+This is the last milestone deliverable of a Nolik CLI app. 
+The app fully covers the functionality described in the grant application.
+It allows sending data from one client to another without a third party.
+In addition to the text form of data, the app enables sending files like photos and videos.
+
+
+**Deliverables**
+
+During the first milestone, I developed the FRAME pallet, which allows managing a Whitelist and a Blocklist of recipients.
+The CLI app has that functionality built-in.
+It will enable us to have a decentralised media platform, which I [described as an example](https://github.com/w3f/Grants-Program/blob/master/applications/Nolik.md#use-case-example) in the grant application.
+
+The app allows to:
+* Generate Wallets and Accounts (addresses)
+* Get free coins from Alice's Keyring account
+* Compose messages with key-value text data and attached files
+* Send a message to one or several recipients at the same time
+* Manage Whitelist and Blacklist of addresses
+* Receive encrypted messages and decrypt them on the client side
+
+I also added an [extra validation](https://github.com/chainify/pallet-nolik/blob/5150d3d045e4b0ed33c636ff74a764fc42bed4eb/src/lib.rs#L235) for the Nolik-pallet that allows to validate the uniqueness of the message, and [covered](https://github.com/chainify/pallet-nolik/blob/5150d3d045e4b0ed33c636ff74a764fc42bed4eb/src/tests.rs#L464) it with unit-tests.

+
+**Additional Information**
+
+It took much more time to build the app, but it totally worth it.
+During the grant I have significantly improved my Rust skills.
+I also struggled with sending data through a Substrate node using the node APIs.
+Fortunately, with the help of Substrate community I've found answers to my questions (
+    [#1](https://substrate.stackexchange.com/questions/1393/getting-extrinsic-data-with-the-transaction-hash),
+    [#2](https://substrate.stackexchange.com/questions/975/generating-an-extrinsic-call-for-a-custom-pallet),
+    [#3](https://substrate.stackexchange.com/questions/903/generating-a-storage-key-when-making-an-rpc-request),
+    [#4](https://substrate.stackexchange.com/questions/2656/decoding-events-with-rust)
+).
+That helped me understand much better how Substrate node works on a low level.
