After my previous posts, several people asked me an update on the mining diversity status.
Here it is :
Mining stats for the first half of September 2016
What can be said?
There is only one big CPU miner left: dodl with a small share of 2.39%
All other small CPU miners hardly grab 9.14% of the pie
gtx-1080 share has fallen down to 13.94% only.
Rabbit mining power has increased to 74.47%
hollywood, b0y2k and aizen definitely gave up.
Here a view of the last 45 days ratio :
When will GPU miner code publicly available?
Some talk have been seen on steemit.chat #mining channel about an expected public release of the GPU mining code. Others says it it not ready yet. Future will tell.
Is one miner having 75% of the mining power a problem?
@dantheman expressed his opinion 3 months ago in a comment to @anonimau5 post:
This is just how hashpower is divided. They are not milking anything, they are bidding the most computational power for the steem. Letting more people know about the mining opportunity would likely increase the difficulty and variance. All told two people with 47% of the hash power isn't that bad.
I personally wouldn't be offended if one person had 99% of the hash power. The security provided comes from the computation work done, not the variety of people.
Anyway, I fell concerned because this lead to a situation where nearly only 20+1 people controls the blockchain integrity. The role of witness become more concentrated and all the small CPU miners are excluded of it. Even if secure, the blockchain becomes less decentralized.
I might be wrong on this. Any comment welcome.
