The 2013-2014 winter contest has ended. Check out our new contest »

Telegram backer, Pavel Durov, will give $200,000 in BTC to the first person to break Telegram' encrypted protocol. Starting today, each day Paul (+79112317383) will be sending a message containing a secret email address to Nick (+79218944725). In order to prove that Telegram crypto was indeed deciphered and claim your prize, send an email to the secret email address from Paul’s message.

Your email must contain:

- The entire text of the message that contained the secret email.

- Your Bitcoin address to receive the $200,000 in BTC.

- A detailed explanation of the attack.

Encrypted Telegram traffic from and to Paul’s account is publicly available for download from this page. You can send Telegram messages to Paul and view his traffic in real time.

To prove that the competition was fair, we will publish the participating keys necessary to decrypt the traffic as soon as a winner is announced. In case there is no winner by March 1, 2014, encryption keys will be published at that date.
