RE: Why Steem curation reward is needlessly unfair and how to fix it
Above example is voting after a whale. Here is another example of voting after crowd:
- assume that a post which already got some up-votes have
total_weight = 10
andrshares = 20
andreward = 400
, then a new voter up-vote with 1 rshare, so her weight = 1 * 0.5 * 10 / 20 = 0.25
, sonew_total_weight = 10.25
, andnew_total_rshares = 21
, andnew_total_reward = 21*21 = 441
, so the new voter will getreward = 441*0.25/10.25/2 ~= 5.4
, which is even higher than above example.
Above examples are based on using
rshares * rshares
as weight for reward distribution among posts. That said, if post A has2x
ofrshares
in comparison to post B, then total reward to post A is4x
of reward to post B.While one's
weight%
to a post is near linear to currentrshares
of the post if she votes late, the reward she can get is also near linear to currentrshares
of the post. That said, by adding a vote to post A the voter will get around2x
reward in return in comparison to voting on post B.This is the reason why the algorithm described in OP encourages voting on already popular posts. If we want to encourage people to find new quality post, it's likely we need to make the weight for reward distribution among posts linear to current
rshares
or less.
