Richard Baranyi (Crypto wizard23) from Slovakia was the first one to solve the t2’15 Challenge. Well done! Congratulations!
The elegant write-up trophy goes to Juha Kivekäs, Finland. His write-up will be published soon so you’ll have a change to evaluate the submission yourself.
Congratulations to both winners! We would also like to thank each one of you who participated. Last but not least. if you have an interesting idea for t2’16 Challenge, please let us know – authors get a free admission to the conference among other perks ;)
