Chinese mining pool F2Pool no longer supports the controversial scaling agreement Segwit2x.
Though the proposal has garnered support from many large bitcoin companies and the majority of mining pools, many take issue with its aim to boost bitcoin capacity by way of a hard fork, a mechanism that could lead the cryptocurrency to split into separate blockchain networks.
Tension has been high with developers already hotly debating the merits of the hard fork (a grassroots movement has sprung up in opposition as well), even though the change is not slated for more than two months from now.
Although F2Pool was an original signatory of the agreement, its operator Wang Chun is now among the proposal's detractors.
