Hi, Codeforces!
Around this time, 15 years ago, I was deploying the first version of Codeforces on a server, registering my account, and writing the first post. 15 years have passed. Well, happy anniversary to us!
For me, this is the most exciting adventure — full of ups and downs, hard work, and moments of joy. What's amazing is that it was never a lonely journey. I've always had caring and reliable friends by my side! That includes the Codeforces team, coordinators and problem writers, our partners in various events, all community members, and, of course, our sponsors — steadfast supporters and helpers.
Look at what we've accomplished together! Here are some of the key metrics over the years. There seems to be plenty to celebrate!
On a day like this, of course, I want to share some good news. And we have some! We have fantastic news!
News #1. Our title sponsor, TON Foundation, has extended and expanded its support of our community. Honestly, I'm amazed by how many innovative projects are working on the TON blockchain. And their long-term and consistent support of the competitive programming community is a great gesture of trust. Thank you, TON!
News #2. In this context, I'd like to announce increased payouts for problem authors and coordinators. We all want to see new and exciting problems and regular rounds. Now, Div 1 + Div 2 round authors will receive 1150 USDT, and Div 2 round authors will receive 450 USDT. I hope this news will inspire the best of the best to organize rounds!
News #3. And that's not all! We're continuing to develop unique competitions in collaboration with TON Foundation. Very soon, you'll be able to participate in the first-ever competition on our platform for programming smart contracts on the TON network! I think this will be a fresh and exciting challenge for the competitive programming community.
News #4. From mid-February to March 9, we'll be hosting an entertaining Codeforces Blitz Cup 2025 with duels and live streams. It will be a small, friendly tournament. Its primary goal is to entertain — we want to try a different format and create a fun show from the community for the community. Sounds interesting?
We want to invite experienced participants from different communities and countries. Participants should be ready for some show elements—mini-interviews, helping with commentary, and participating with screen-sharing and webcams. If you're red (or have been red) and are interested in giving it a try, fill out the participant application form, and we'll consider your application!
That's all for now, I think. And now I'll go enjoy a piece of birthday cake.
Mike
P.S.
I've often been asked about repeating the crowdfunding campaign we last did five years ago. It's a great idea, and I'd love to do it again! Right now, there are some organizational and bureaucratic challenges to launching it properly. Let's see how they get resolved. Maybe we'll kick it off soon—or perhaps we'll wait for the next round binary date at 16 years!

Mikhail, you're doing a great job, keep up the good work!!! I believe that if this is not the best, then it is one of the best platforms with similar content. There is only one wish, I would be glad to see a more beautiful UI shell, but I think this may scare off old users, so the choice is yours))) If I'm from Russia. Good luck!
It's a checkbox, but apparently, all fields are mandatory. Can I just choose commentary?
Also, I'm a bit confused that the blogpost states that Blitz Cup will be held from mid-February to March 8, while the form states that contests are going to be held only on March 8-9.
Maybe some qualifying rounds for selection and initial seeds at usual codeforces time, and back to back 1v1 duels on March 8-9.
happy birthday codeforces
Sorry, I lied a little. I didn’t go to eat cake. My brothers came from far away, and we went to the gym. The three of us in the gym for the first time!
Huge jacked men
Mike, how much do you bench?
Teach how to be buff :orz:
Nice body sir.
is it real?
Hi Sir, I don't mean to be rude but your hair are ruining the picture.
Happy Birthday Codeforces !! Wishing you a long, healthy and bugfree life ahead :D . Hope you keep hosting more and more contests with amazing problems ...
My dear CodeForces, Wishing you a very happy 15th birthday.. May you stay one of the leading platforms for CPers to learn and hustle..
Does this mean we get 15 Year Anniversary Badges !!!!
Cheers to 15 years of Codeforces! Thank you for being the best place to challenge ourselves and improve our coding skills. Long live Codeforces! Here's to many more! <3
...
What happened in 2020?
Boy, you're in for a ride.
I was here :).
I made it to my first anniversary!
About blitz cup, is it intended that you can only select all boxes?
Give me two points To celebrate this great occasion
will we have a chance to get badge like this in 15th anniversary?
There's surely many people who can do Blitz Cup duels but can't share webcam, join interviews or commentate...
How time flies.....
как же время летит быстро.....
I was here... Happy Birthday CODEFORCES.
Leaving this comment as a reminder to improve before Codeforces' 20th anniversary!
Leaving this comment so when i see it later I'll remember that i used to do cp on Codeforces.
Happy Birthday Codeforces. Probably the only website where I have been active since last 8 years :)
thank you for an amazing platform, best wishes for the milestone and the journey ahead
It's strange that the server of Luogu is slower and less but it has more than $$$200$$$ million submissions.

My upvote made it +2025!
What a pivotal time!
My introduction to Codeforces at the age of 15 opened a door to a new world that I am still deeply involved in today. Thank you, Mike, for creating a platform that enhances critical thinking on a global scale. I hope this achievement always remains a cherished memory.
I have a question.Does codeforces' headquarters never reply to Talks send to them??????????
Do you have any updates on the Codeforces Blitz Cup? It'd be helpful to know whether the event is still planned for March 8-9 and whether I was selected to participate since I'd want to make other plans for that weekend if not.
