SegWit will not even work unless 95% of the miner hash implements it.
One mining pool with 8% hash has stated they will block SeWit, and want BTC unlimited instead.
95% is a huge number. I don't know the data, but I really hope the you are wrong. Because then this will take a (too) long time to get traction...
And BTC unlimited.. is an altcoin. If they want to mine altcoin, nobody forces them to stay on this chain....
And if they leave this chain, their 8% doesn't matter anymore.
Not the altcoin but a proposal for blocksize is also called BTC unlimited, I can see how that is going to confuse people.
http://www.investopedia.com/news/what-bitcoin-unlimited/A new term, ‘Bitcoin Unlimited’, has been floating around for some time now. So what exactly is Bitcoin Unlimited? Will it result in a hard fork (forced splitting off of the currency)? (Related: Does Ethereum's Hard Fork Undermind Smart Contracts?)
The issue revolves around the size of the blocks which are added to its blockchain. Blocks are files where data pertaining to the bitcoin network is permanently recorded. A block records some or all of the most recent bitcoin transactions that have not yet entered any prior blocks. Thus a block is like a page of a ledger or record book. Each time a block is ‘completed’, it gives way to the next block in the blockchain. A block is thus a permanent store of records which, once written, cannot be altered or removed. (Related: Bitcoin is Money, Rules Federal Judge in Landmark Case.)
Bitcoin blocks have a limited ‘storage’ capacity of 1MB since the beginning and under the current popular system of Bitcoin Core. However, Bitcoin Unlimited argues that the size of these blocks should be increased as it would enable smoother running by decongesting the blocks. Unlike the present rigid size of 1MB, Bitcoin Unlimited advocates complete freedom and flexibility to increase the size of blockchain and this will be done by miners. So, if there is a consensus on this, we will have a new bitcoin blockchain with large-sized blocks.
Sorry it is 95%.
https://bitcoincore.org/en/2016/10/27/segwit-upgrade-guide/Miners representing 95% or more of the total Bitcoin network hash rate must signal support for segwit in order to lock-in segwit’s activation.
Started: Segwit will be in the started stage from the beginning of the first retarget period on or after 15 November 2016 until it either activates or is considered failed (under BIP9’s policy) after one year of not reaching locked-in. During this time, miners who are willing and able to enforce segwit’s new consensus rules will be signaling their intent to do so by placing bit 1 in the block header versionbits field.
Locked-in: if 95% of blocks during a 2,016-block retarget period signal support for segwit, the segwit soft-fork will be locked-in with activation scheduled for 2,016 blocks later (about two weeks).
Activated: after the completion of the locked-in period, the miners who signaled readiness to enforce segwit will begin producing segwit-style blocks that contain transactions with segregated witnesses
FYI:
A hard fork would have only require 60% or 70% to make the switch.
