Porting Bitcoin 0.9.3 to Darkcoin
=================================
Staging tree for Darkcoin-0.9.3.
Staging tree for Darkcoin-0.11.0.
DONE:
@ -17,19 +17,19 @@ DONE:
- Adjusted algorithm (X11)
- Updated subsidity function (Block value)
- Adjusted wallet keypool size to 1000 and added loading indicator on fresh wallet load
- Adjusted difficulty and blockvalue (KGW, DGW based on blockheight)
MUST-HAVE:
MANDATORY:
----------
- Adjust difficulty (KGW, DGW based on blockheight)
- Add masternode payment checks a.k.a. enforcement (based on blockheight)
OPTIONAL:
---------
- Remove Bitcoin dead weight (SHA256, hardcoded keys, nodes)
ADD-ON:
-------
- All the above for Testnet (including complete testnet reset)
- Update strings and wallet layout/branding
- Include Evan's public key for msg signing
