The mining pools AntPool and BTC.com, which is operated by the largest manufacturer of mining equipment Bitmain, reject all SegWit transactions in the Bitcoin network. This is reported by a well-known trader WhalePanda, with a link to users of Reddit.
So, the user -johoe stressed that AntPool managed to get four blocks in a row, thereby filling the memory card with SegWit transactions. If on block # 547 566 the commission was 0.04 BTC, then on the next block, which went to BTC.com, it was already 0.24 BTC.
Nevertheless, many users agreed that pools simply harm their business because of ideological convictions, while the Bitcoin network is resistant to this kind of censorship.
In early September, AntPool was accused of using the AsicBoost optimization algorithm on block # 540 032.
After a month and a half, Bitmain introduced updated software for Antminer S9 devices with this algorithm, and soon the solution was implemented in the Braiins Wolfram operating system from Slush Pool.
