- Primecoin network reached a new record last month for 13-primes, a 107 digit Cunningham chain of first kind. This breaks the record held by Primecoin in September last year, a 94 digit Cunningham chain of 2nd kind (https://github.com/primecoin/primecoin/wiki/World-records).
- Riecoin appears to be ready for launch. Riecoin was in development by gatra, initially hyped as a tester of Riemann hypothesis (thus the name) last year. A brief read of the its pre-launch description indicates that the proof-of-work is now a slight variation of Primecoin's proof-of-work, searching for a specific type of prime constellations instead of Cunningham chains. The author of Riecoin compared it with Primecoin, although most of his criticisms of Primecoin are due to lack of a good understanding of Primecoin's design choices. In fact I have described most of them in my Primecoin paper. I certainly welcome other work based on Primecoin however it would be nice for the author to give proper credits.
Have fun!
