Telegram Contests

🏆 Telegram Contest for JavaScript Developers, Round 2: Results

We were pleased to see both participants from Round 1 and those who joined the Telegram Contests for the very first time! The Contest Task, which covered multiple areas of the app (implementing a new feature, adding another feature that heavily relies on the existing codebase, and fixing an obscure issue), proved to be particularly challenging for the contestants, with no one completing all three tasks.

Most contestants focused on the Media Editor, so the judges adjusted their evaluation accordingly. After many hours of testing, we are pleased to confirm that Hip Hyena secured 🥇1st PLACE by delivering the best media editor among all the submissions. This time, given the input each contestant contributed, we will reward everyone who implemented at least one contest task, even if their implementation wasn't perfect.

Meet the winners!

Telegram is hosting a contest for JavaScript developers to implement two new features into Telegram Web and address the scrolling issue on Chrome for Android.

The Task:

1. Implement Media Editor and Multiple Accounts into Telegram Web K based on the provided mockups.
2. Web K is currently experiencing scrolling issues when used on Chrome for Android. This issue causes noticeable lagging on devices with 120 FPS displays, particularly when scrolling through any entities containing numerous media elements – essentially, any channel with larger message bubbles and multiple media items. (You must investigate the issue, provide a detailed explanation of it, and implement a fix that will address the issue.)

Evaluation Criteria and Requirements:

General
– No third-party UI frameworks are allowed.
– The submission must be consistent with the existing Web K codebase.
– Your implementation must work flawlessly on desktop Chrome (across Linux, macOS, Windows) and Safari on macOS. Proper support for other browsers and mobile environments (Android, iOS) will be considered a bonus.

❗️Your app must precisely follow the provided design mockups. Entries that fail to do so will be severely penalized.

Further Clarifications:

Media Editor
– You must not use any libraries or components (i.e., from other existing media editors) for any parts of the Media Editor. All the features presented in the mockups must be built from scratch.
– It is acceptable to send static media when an animated sticker is added to a photo, though a proper conversion into a GIF would be considered a bonus.

Multiple Accounts
The app must properly handle the databases from several accounts, support simultaneous notifications, and oversee all possible edge cases, including forced logout from another device. For reference, you may check official Telegram apps.

Submissions:
Contestants will be able to submit their entries to @ContestBot at a later date. We will further clarify the submission instructions closer to the deadline.

P.S. Winners may be offered a chance to explore further opportunities with Telegram.

🏆 Design Competition 2024: Results

This was by far the most thrilling design contest we've ever held! We would like to express our sincerest gratitude and admiration to each and every contestant – both those who took their very first steps in the challenging world of design and the noble design veterans who set aside some time from their projects to contribute to a better Telegram of tomorrow. ✨

You all are amazing, and we thank you a lot for your fantastic designs! 💙

Now, let us shed some light on the judging process in this competition. The Telegram Design Team joined forces with the Telegram Contest Department, and each judge spent dozens of hours watching and sorting through all the submissions. Once the judges completed their solo evaluations and highlighted the most promising discoveries, the whole jury met to watch and discuss together all the submissions that were not instantly discarded. Aside from the initially mentioned core criteria, another important consideration was, "How close is this video to the ones we make for Telegram Blog?" 🏅

Thanks to this multistage checking, verification, and discussions, the members of the jury were unanimous in the prize distribution.

In order to justly apprise all the notable and solid works, we've decided to increase the prize fund by another $24,000, totaling $54,000.

📱 🤝 📱 With this competition, we are also introducing a new Contest Rewards 🤑by giving out your prizes in USD₮ on TON – to ensure smooth and instant payouts.

Without further a do, please meet the winners!

🏆 Telegram UI Competition for Android

Prize fund: Up to $30,000
Deadline: 23:59 on December 7th (Dubai time)
Who can participate: Everyone
Results: December 15th, 2023

Telegram is hosting a competition for Android developers to implement a new animation for deleting messages.

The Task:
Implement a new animation flow for deleting messages into Telegram for Android similar to the provided demo (the demo is a recording of a beta feature on Telegram for iOS). Your solution should support all entity types for both incoming and outgoing messages across all types of chats and channels.

The most preferable outcome is likely to be achieved by taking the component SpoilerEffect2.java as a reference. However, you may opt for your own approach as long as no third-party UI frameworks are used.

Evaluation Criteria:
The primary criteria for determining a winner will be the app's stability and performance while replicating the provided demo as closely as possible (the animation in general, also the particle flow and dispersion).

Your app must be free of significant flaws (including crashes, visual glitches, noticeable element blinking, layout errors, and more).

Devices:
During the evaluation stage, submissions will be tested on a broad range of devices and Android versions (Android 7-13) not limited to the mentioned below:
• Samsung Galaxy (A12, A32, A51, S22 Ultra)
• Xiaomi Redmi (9, 9A, Note 8 Pro, Note 11)
• POCO (X3 Pro)
• Oppo (A54).

Telegram for Android utilizes performance classification with SharedConfig.getDevicePerformanceClass() – each device is defined as HIGH, AVERAGE or LOW. In order for your app to qualify for a reward, your solution must work flawlessly on HIGH and AVERAGE devices. Introducing a proper implementation for LOW devices will be considered a bonus.

Submissions:
Contestants will be able to submit their entries to @ContestBot later. We will further clarify the submission instructions closer to the deadline.

P.S. Winners may be offered a chance to explore further cooperation opportunities with Telegram.
