Hello

I'd like to receive some feedback on an idea for an altcoin, if
technically oriented people are still reading this board.

It is very simple.

The network will mint PoS coins, Peercoin style with very
short block period.

It will also mine a colored coin (representing an asset) using
proof-of-work with very long block period.

(The idea being that the asset can be traded on market with
the PoS coins.)

Both kinds of blocks co-exist in the same chain.

Seems to me you could get the best of two worlds, fast confirmations
with the short PoS block times (10-30 secs) and stability with the
long PoW period (8-12 mins).

Am I missing something? Has it been done?

I'm not generating any shares and
I'm trying to figure out which one is to blame, the miner
or stratum.

It then recycles like this, the "params" get send like above and new job_ids.
Hashing happens but not shares.
Can't be that difficulty is too high, because I can mine blocks with wallet just fine.

Any ideas? What can I do to get Stratum session id?
