Greetings!

In the past 18 month, we've been struggled to design a pure PoS algorithm which is truly secure, and fully decentralized.

Many of you may know, that most PoS algorithms out there are not secure, or not fully decentralized. It's really not an easy task to fulfill these two requirements at the same time.

But we found a beautiful solution at last. We write an white paper about the algorithm, and we also make it into a new coin.

We deeply believe that PoS is a very good direction, and we hope there will be more people knowing about our algorithm(LF-PoS), and more discussions about it.

This thread can be used for algorithm discussion. We'll be on the forum every two days or so.

Thank you very much for your time!

========================================

About security:
Please have a look at the "Infeasibility of Private-Chain Attack" section of our white paper, there's a discussion that why PoS must NOT compare with infinite long branches. There're a lot more things to talk about security, we'll update this post later.

About decentralization:

• PeerCoin has a centralized checkpoint broadcasting mechanism(ref);
• Nxt has a hard coded chain switch limitation (720, ref) to prevent private chain attack which sacrifices decentralization. Here's a great article talks about this matter(section 4.3, “Long-Range” versus “Short-Range” Attacks).
