Bitcoin’s consensus layer has remained unchanged for over two years now. Since Segregated Witness (SegWit), which activated in August 2017, no hard fork or soft fork protocol upgrades have been deployed at all, marking Bitcoin’s longest stretch without consensus forks so far.
But this stretch may soon come to an end: several backward-compatible soft forks are currently in development. Optimistically, some of them may go live in 2020 — if they gather sufficient support from the Bitcoin ecosystem. |
