Ethereum Core Dev team is implementing Metropolis Byzantium
https://np.reddit.com/r/EtherMining/comments/6ywlxg/update_from_todays_ethereum_core_dev_call_for/, which will:
Metropolis Byzantium hits testnet on September 18th
Difficulty Bomb on September 22nd will reduce current income by approximately 20%
Metropolis Byzantium go live on October 9th (not a final date, subject to change)
Mining rewards will increase by approximately 23% after Metropolis Byzantium goes live
A group of miners, investors, developers (mainly in China??not confirmed) believed that Ethereum Core Dev team will hurt their interests:
http://www.cahf.co/So they planned a hardfork:
"This plan is for Community Activated Hard Fork, or CAHF. You can find technical specs here:
https://github.com/CAHF/Ethereum-CAHFCAHF will be activated “right before” Byzantium HF. We will update the specific time ASAP when the blockstamp of Byzantium hardfork is updated.
CAHF chain will follow and fork existing rules of the Ethereum’s main-chain, except for issuance reduction and POS. We will maintain our POW chain which will be the Ethereum-POW chain (when Ethereum hardforks to POS).
Despite of maintaining “large” network of cryptocurrency costs lots of human resources and other consumption, we will issue 10% of pre-mine inflation for “Develop and ‘storing value’” stake. (This will be 1% inflation of total supply)
Once we mine our stake ‘privately’ and check that there is no further problem on the chain, we will make our repository ‘public’ and release our CAHF geth node. (Will be updated to our twitter account)
Our CAHF developers are serious for monetary policy of CAHF chain therefore we decided CAHF’s total supply approx. 1 billion. When CAHF chain issued total 5 hundred million, we will halve the issuance to 2.5. This decision is from that “Ethereum is not an asset, is a currency”.
We share the same belief with some very early Ethereumers, that decentralization means that more than 1 billion people in 200 countries are using Ethereum as a saving currency and payment network, which comprises of hundreds of thousands of Ethereum services, traders, exchanges and software to be decentralized. We do not believe that decentralization means a decrease of issuance so there will be no more inflation before POS change or change to POS so some accounts that has larger volume of Ethereum takes most of issuance than who doesn’t."
