Update networks.py for digibyte v2.0

[StormMiner]

Updated Subsidy_Function to reflect new reward scheme.
For Every 10080 Blocks after the 67200th Block: the Reward is reduced by 0.5%

[Rav3nPL]

It can (and should) be calculated in separate function.
Subsidy function is not used all the time (block value i in block template).

[StormMiner]

So, what changes do you recommend?

[StormMiner]

Should we stick to 8000 * 100000000 and change it to that?

[StormMiner]

oh. Nice!

[Rav3nPL]

@chaeplin so it is working correctly or no?

[chaeplin]

@Rav3nPL

• darkcoin subsidy working
  https://github.com/chaeplin/SUBSIDY_FUNC/tree/master/darkcoin-subsidy-python
  http://darckcoin.mine.nu/
• digibyte : python test.py working, I don't have digibyte instance.
  https://github.com/chaeplin/SUBSIDY_FUNC/tree/master/digibyte-subsidy-python
• https://github.com/Sykh/p2pool-cache/ has python get_subsidy sample.

[StormMiner]

Hi Rav,

Please update p2pool-rav with Chaeplin's subsidy function and the networks.py subfinc

The entire dgb p2pool network will switch over.

I dont think we'd mind changing the port, either..

[chaeplin]

@StormMiner
change of IDENTIFIER, PREFIX( p2pool/networks.py ) will be needed
to cut off forked p2pool node which does not maintained.

[StormMiner]

@chaeplin what should it be changed to?

[chaeplin]

@StormMiner
As far as I know, for p2pool/networks.py, random 19 number to hex will work.

printf '%x\n' 5234567890123456789
48a4ebc31b798115
printf '%x\n' 6234567890123456987
5685a276c2dd81db

    IDENTIFIER='da0fa0c30b6fab6a'.decode('hex'),
    PREFIX='c30fa0b60da0c3da'.decode('hex'),

to

    IDENTIFIER='48a4ebc31b798115'.decode('hex'),
    PREFIX='5685a276c2dd81db'.decode('hex'),

[StormMiner]

@chaeplin sounds good.. thx
@Rav3nPL please update it, ill waterfall it to all p2pool operators... thx

[Rav3nPL]

So, we are changing this (subsidy function) or not?
Those identifier and prefix too? If yes (identifier/prefix), it will start new share chain.

[gururise]

I'm ready to switch over as long as the rest of the Digibyte community is as well. Is someone coordinating the switch?

[StormMiner]

Majority (i.e. half) have already switched over to the new share chain (using the same identifier and prefix and also the dedicated subsidy function.)

[Rav3nPL]

@StormMiner can s1 make proper pull request for this new function?
