The month of September is wrapping up, and the planned November Segwit2x (BTC1) hard fork is steadily approaching. According to the BTC1 roadmap, a block between 1MB and 2MB in size will be generated by miners raising the block size limit at block height 494,784. Over the past few months, Core developers and supporters have been vehemently against the block size increase but are also upset that the Segwit2x working group will not add replay attack protection.
