The VoIP competition ends tomorrow.

To submit your apps, send /start to @jobs_bot, then choose Voice Calls Contest and answer the bot's questions. It will accept a .ZIP archive with your submission.

All entries will be published on contest.com on Sunday.

We received 30 submissions for the first round of the VoIP contest. All entries are available for public testing on contest.com/voip-contest

Everybody's welcome to check them out while we're getting ready to announce the results of the design competitions.

Stay tuned for the Telegram JavaScript competition, which will start tomorrow.

As for the other recent Telegram competitions, we are planning to announce their results over the next few days.

The Telegram contest for JavaScript developers is starting today.

Prize fund of the first stage: $80,000+.
Prize fund of all 3 stages: $200,000+.
Dates: Nov 3 - Nov 17 (23:50 Dubai time).

The goal is create a simplified web version of Telegram without using third-party UI frameworks. The app should include login/signup flows and allow viewing chat and message lists. The design implementation should be identical to the mockups attached below.

You are welcome to view the API docs and inspect the source code of existing Telegram apps to get an idea of where to start. The main criteria for us to identify the winners will be the speed, size and attention to detail of their apps. Implementation of additional screens from the mockups (e.g. message creation, media viewer, shared media, settings etc) will be counted as bonus points. Apps without basic functionality (i.e. login/signup and chat/message lists) will not be awarded. All the paths in the scripts should be relative.

For avoidance of doubt, using UI frameworks such as React and Angular is not allowed. Using data frameworks such as tdlib is possible in theory, but is likely to result in unacceptable increase in loading times compared to plain JS solutions.

The authors of the best apps will share the $80,000+ prize fund and will be able to take part in stage 2.

We will publish the instruction on how to submit the apps soon. Good luck!

The results of the sticker design contest are ready! 🎉
We have 29 first prize winners who will receive $1000 each – and an opportunity to work with Telegram on completing their sets (up to $200 per extra sticker). In addition, 40 stickers designers have been awarded the second prize and will receive $500 each.

The JavaScript contest ends on Nov 17, 23:50 Dubai time. You can now submit your files to @jobs_bot.

After the end of the contest, we will release all submissions for public testing, each entry on its own subdomain.

Please note that we expect a .ZIP file containing an index.html file in the root folder. The archive must include unobfuscated code (this includes minify).

UPD:
- You may include two versions in your archive, src (unobfuscated) and dist – each in its own folder.
- If you do that, put index.html into the dist folder.
- Only dist will then be hosted for public testing.

Also, stay tuned for the Data Clustering Contest which will start on November, 18.

The results of the blockchain contest are ready. The total prize fund of $235,000 will be distributed among 41 winners. We are impressed by the skill of the participants and congratulate all the winners.

We are grateful for all the suggested fixes to TVM and FunC. Most of those have been implemented, and the TON TestNet has been restarted today.

We will announce Stage 2 of the blockchain competition in the next few weeks. Please note that the TON security bug bounty program is extended – we will be accepting and rewarding security bug reports even though this stage of the contest has ended.

Here's a sneak peak of the data format you'll have to parse in order to compete in the Data Clustering Contest that starts in 2 days.

Following questions from participants of the JavaScript contest, we've updated the section about test phone numbers for testing user authorization flows (previously available here).

The results of the themes contest have finally arrived. We carefully inspected each of the 341 themes submitted by the 277 designers and selected the ones we considered best. While none of the themes submitted are perfect, here’s how we identified the winners:

1. Themes that supported more than 2 platforms were slightly prioritized.
2. Themes that could be built within a few minutes using the Telegram UI were discarded.
3. Themes that we deemed unusable (e.g. those with low contrast / dissonant color palettes) were likewise discarded.

Thank you for taking part in this competitive process. We hope you had fun!

115 scripts have been submitted for the JavaScript contest. They will be made publicly available tomorrow at contest.com. Also stay tuned for the Data Clustering Contest, which starts tomorrow.

All submissions for the first stage of the JavaScript Contest are now available for public testing on https://contest.com/javascript-web

Everybody's welcome to check them out. Stay tuned for the Data Clustering Contest.

The Telegram Data Clustering Contest starts now.

Based on the input data we provide, you are expected to develop an algorithm that:

1. Identifies content in English and Russian and discards the rest.
2. Identifies news articles from the result of (1) and discards the rest.
3. Classifies each news piece from the result of (2) into one of these 7 categories: Society, Economy, Technology, Entertainment, Science, Sports and Other.
4. Identifies news pieces about the same event and groups them together into news threads.
5. Sorts news threads based on perceived importance.

Below is the sample input data. We will be publishing more sample data sets as the contest progresses. Check out the detailed description of the contest task here (and here in Russian).

Participants have two weeks until December, 2 (the deadline is 23:50 Dubai time) to come up with a solution and upload it to @jobs_bot.

The authors of the best solutions will share a prize fund of $100,000 and will be able to take part in the second stage of the contest, getting a chance to claim another $100,000 in prizes.

More sample data for the participants of the Data Clustering Contest. Have fun!

Please find the latest data sample for the Data Clustering contest below.

Note that, following questions from the participants, we decided we'll also accept archives larger than 200 MB (up to 1,5 GB) with an appropriate penalty.

Also added a section for Clarifications to the contest page.
