Bitcoin Cash to Avoid Chain Split Over Controversial ‘Mining Tax’
The proposal was first made by the CEO of major cryptocurrency mining pool BTC.TOP, Jiang Zhuoer, and would see miners donate 12.5% of their block rewards to BCH’s developers to grow its infrastructure. It added, however, that those who didn’t donate would see their blocks get orphaned.
The community’s response to the proposal later saw the CEO of Bitcoin.com, Roger Ver, drop support for it over the risk of a chain split. Jiang Zhuoer himself, later on, dropped support for the proposal and said he would use his 3,500 PH/s of hashrate to vote against the proposal.
Bitcoin ABC, the dominant Bitcoin Cash node client, has however, added support for the proposed “tax,” which could be activated if miners representing a specific amount of the hashrate signal support for it.
Based on community feedback a new Infrastructure Funding Plan, with miner activation and multiple projects, has been created. Bitcoin ABC intends to implement this plan.
Thank you @JiangZhuoer and the mining community for driving this initiative. https://t.co/sEhFq1DlLU

For now, Support for the proposals appear to be low, but there is still a chain split risk of miners choose to vote for it. In response, developers created the Bitcoin Cash Node client, which is an initiative that will “neutrally follow the longest Bitcoin Cash chain without contributing to the risk of a chain split.”
Other nodes have claimed they will switch to Bitcoin Unlimited, another node client that hasn’t added support for the proposal. As CryptoGlobe reported, an anonymous group of miners supposedly representing 1.6 EH/s of the hashrate threatened to launch a hash war that could have also led to a chain split over the tax.
The Bitcoin Cash network, it’s worth noting, is I a fork of the Bitcoin blockchain, and has endured a chain split in November 2018, when Bitcoin SV was created.
