A completely new application (Messenger) for Android has been developed, using the redesigned tonlib library. The library was processed to reduce the size, the minimum necessary functions were left. Queries are made using Java wrappers for classes (Cell, CellBuilder, CellSlice).

Code func, fixed and located at this address.

All time crashed app.

WEB SCORE: 2.66
Opening Section – 2
Concept Explained – 2
Language – 4

OK design (ICO/Anti-virus style). Opening paragraph describes a generic encrypted messaging app – any centralized app fits that description. Doesn't quite answer the questions "who is this for?" and "why do I want this?" Ignores the issue of having to pay for messages and storing message history.

VIDEO SCORE: 3
Narration – 3
Visualization – 3
Concept Explained – 3
Bonus: Language +0.25
Bonus: Soundtrack -0.25

Captions without visualization for the first half of the video.
Difficult to make sense of the interface from the small sims (could've used zoomed-in interfaces to highlight particular features). Watermarked soundtrack.

=====
Base Reward: EUR 3,500
Bonus: +1,000 (Android app)

OLD BUGS FIXED: 0/1

NEW CRITICAL ISSUES:
It's possible to replay past messages. There is msgTime, but message signature is checked only over the message body, so msgTime can be forged.

Bug Penalty: - EUR 1,500

Total: EUR 3,000

Transferred msgTime to the message body, now msgTime will participate in
the verification of the signature.
