Weekly Update #199

•Peercoin v0.6 is in development.
•In v0.6 users can choose to disable checkpoint enforcement. In this mode, the node does not automatically reorganize to the blockchain fork where the checkpoint resides. Instead, it shows a warning message that checkpoint is on a different blockchain fork.

Have fun!

In the prerelease thread it says there are centrally broadcasted checkpoints to defend against 51% attacks. That thread was started in 2012 and the codebase may have changed since then, but has a new way to defend against 51% attacks been implemented? Is that why users can now choose to disable checkpoint enforcement?

I believe the original idea was to implement checkpoints until PoS matured on the network and could act as a defense mechanism if PoW was ever attacked. It has now had years of maturation.

PoS security is all about distribution and network effect.  PoW distribution and general expansion of the network has had a lot of time to mature.  These factors make PPC ready for the next step of decentralization.  Before long, PPC will easily be considered the most decentralized cryptocurrency in existence, especially when compared with mining cartels.

PoW doesn't play a role on Peercoin network security. PoW is only for fair distribution.
Peercoin security solely relies on PoS. Peercoin PoS security has been improved in Peercoin v0.5+.
