Idea & concept

Current blockchain expierence (like Steem) showing problem of huge size of state. There is no reason to save content data in objects and memory.

Refuse from flags make posibility to reverse reward window. In new concept reward window working in past timeline. This nuance allowing pay award instantly.
Summary it resolve problems with big size of state, content/vote object storage while payout proccessing, limitation with award(vote) target.

Custom operation is new type for any data architecture. Each custom operation increase account custom_sequence counter. Award targets account also can contain custom_sequence and memo for additional information about award decision.

DPOS2 not fair enought. In that case was implemented split vote shares from each accounts between personal selected witnesses. In new splitted DPOS each account can split vote between 100 fair witnesses for true decentralisation.

Implemented inflation consensus for witnesses. Witnesses can setup percentages for witness reward, committee and reward fund.
