It is pretty amazing how we only have 103 pages. Maybe the peercoin forum is where a lot of chatting is taking place.

I was wondering about the limits of mining and I read somewhere that it was supposed that PoW would eventually be replaced by PoS (due to power consumption, reaching limits on coins issued, viability of the network, ie keeping the verification process as decentralized as possible.)  It would make sense to me.

Not that I know - I follow Peercointalk announcements regularly.

However, that does not mean at all that version 0.6 is dead, on Github there are regularly commits. If I'm right, then the development branch of 0.6 is this one: https://github.com/peercoin/peercoin/tree/0.6-hrobeers

The last commit was 15 days ago, the master branch was updated 24 days ago. Maybe they're testing now.

A short remark regarding smart contracts: If I have understood it the right way, then Peercoin's smart-contract-like features via PeerAssets will not be turing complete (like Ethereum's smart contract platform). But turing complete smart contracts have still to prove that they are really useful. So that is not necessarily a "problem" if turing-completeness is lacking, if major use cases (like dividends) can be implemented in another way.

bug in wallet and lost all my coins, another scam coin.

Ah Peercoin! Has survived the test of time.

Any new developments?

When will v.6 release? New wallet?
