So it's just as self-regulating process as with the usual PoW mining.

Oh, of course. I knew that PoS has its own difficulty to regulate the number of blocks generated, but I was in stupid mode. Apologies for my temporary brain fart.

I've been thinking about a coin with fixed reward PoS for a while (...it's probably already been done...)

Are PoS minted blocks also eligible to generate further PoS themselves once they've matured sufficiently? If so, surely there would be issues with exponential runaway? If you start with 1 ORB then do nothing, after 30 days (or whatever) it will PoS mint an additional 1 ORB, so your balance is now 2 ORB; after 30 more days, you will PoS mint an additional 2 x 1 ORB, so you now have 4 ORB, and so on. In a year your 1 ORB will grow to 4096 ORB, at the end of 2 years it will be 16 million.

This can't be right. So is there some code to prevent PoS funds minting more PoS blocks?

No any "exponential runaway". If many people (more than needed to generate the target number of PoS blocks) will do so it just rise PoS difficulty up while keeping amount of PoS blocks (and coins productions via PoS) at same level. (= each person running PoS will get less coins)
And with high PoS diff it is better(=greater probability of finding the block) to have in wallet few relative large incoming transactions vs very many small transactions.

So it's just as self-regulating process as with the usual PoW mining.

Plus i thinks you miss this: "The minimum amount to generate a PoS block is 20 ORB."
So just one PoS block is not enough to generate another PoS bloсk even now (at very low PoS diff) only if stack few PoS blocks up to 20 ORBs at same address.

Couple of patches to allow Orbitcoin to compile cleanly on FreeBSD:

util.cpp (in function LogStackTrace) :

Code:

1000c1000
< #ifndef WIN32
---
> #if !defined(WIN32) && !defined(__FreeBSD__)

Copy makefile.unix to makefile.freebsd, then patch:

Code:

15a16,21
> BOOST_INCLUDE_PATH=/usr/local/include
> BDB_INCLUDE_PATH=/usr/local/include/db48
> BOOST_LIB_PATH=/usr/local/lib

To the rescue again I see

I really hope that people appreciate your improvements to PoS and the contributions this brings. Perhaps you should write a short paper on the short comings of the original PoS and explain the work you have done here?

I'm mining Orb but if anyone has 0.5 Bitcoins worth then please send me a PM.
