Hardfork 21

---

As of last Thursday, our witness has been running HF 21 Stable and Sound, after running it on the backup server for a couple of days.

Fun fact: We are using MIRA to test it and without too much effort yet it's running at 25gb ram. Replay was about 16 hours.

Convergent Linear Reward Curve + 50/50

---

The reward curve has been changed to convergent linear (n^2/(n+1)). Meaning it starts out superlinear but it will bend down towards linear the more stake is concentrated on the content.

This means a post needs to get a certain amount of votes before the curve become linear. According to the latest interview with @vanderberg, that's around the $6-$7 dollar mark (Maybe a little lower now with STEEM price coming down a bit).

The idea is to further increase the voting on quality content. A separate downvote pool is introduced to increase the number of curation options users will have to reach this goal.

Another tool introduced is the introduction of a 50% curation reward from 25% further incentivizing better curation by stakeholders.

While we don’t exactly agree with the change in the reward curve (we prefer linear) we do like the 50/50 and downvote pool for more curation options and to combat abuse).

SPS - Steem Proposal System

---

Hardfork 21 also introduces the Steem Proposal System.

It will allow for people to submit proposals for funding which will be funded by donations and inflation (10% from the current reward pool).
