A defined route for SegWit started days ago with the activation of BIP91, establishing a schedule of activities for the effective activation of the Segregated Witness protocol. Since then, all blocks that did not signal BIP141 for SegWit activation would be orphaned from the network. This meant that miners who add blocks to the main chain without pointing out BIP141 could lose the approximate reward of 14 BTCs or $ 35,000.
Today, the first difficult period of 2016 completed blocks for the BIP141 mining signaling - the time measured in block indicated to approve or block a proposal - ended with full support. In fact, 100% of the last 144 mine blocks have signaled SegWit since Sunday. So the process of potential activation of SegWit was practically irreversible. The processing power required to activate SegWit fell to block # 477792 added by BTCC.
This means that a complete signaling period has been completed and a new period has been opened to approve SegWit as proposed in the Bitcoin Core roadmap. From this moment, if the support to SegWit is still complete, in a few days we will reach a point of no return regarding the implementation of the proposed scalability,
