VIZ 2.2

Idea & concept

Initialy vesting shares have part of emission. In that way ratio between total_vesting_fund and total_vesting_shares was slightly increased (like +0.0056%). After vesting shares emission was remove that ratio was badly affect on user expierence (most popular question was: "Why 1 VIZ not equal 1 SHARES"). That's why shares was recalculated and set up with ratio near 1.000:1.000000. Witness system work very well in Fair DPOS, but consensus can be more effective if witness will have panalty for missing block. Penalty system by default reduce 1.00% summary votes for 1 day. That penalty system must balance witnesses with network problems until they will be solved. Added additional transaction bandwidth usage. Data operations in that case is classificated as containing string variables without size restrictions.
