+# 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/Support%20Docs/milestone-deliverables-guidelines.md).**  
+
+* **Application Document:** https://github.com/w3f/Grants-Program/blob/master/applications/cryptex.md
+* **Milestone Number:** 2
+
+**Context** (optional)
+
+The Etf Network is a Substrate-based blockchain that utilizes identity-based encryption and zero knowledge proofs to enable "encryption to the future", or timelock encryption. It uses a slot-based consensus system as a reference clock to which messages can be encrypted. The initial implementation uses a fork of Aura to implement a proof-of-authority version of ETF, where authorities are IBE master key custodians. Valid blocks authored in future slots contain the corresponding secret keys. To put it another way, each slot has a unique, publicly calculable identity, and whenever a block is authored in that slot, the identity owners leaks their secret key.
+
+In the 2nd milestone we deliver tools requried to perform timelock encryption on the network. Additionally, we deliver a typescript library and custom smoldot/substrate-connect fork to easily integrate into a user interface.
