Expected timeline:

  • 2021 March 17-31: Full node software released with Taproot activation deployment.
  • 2021 July 23: Economic majority has upgraded. Miner signalling begins to indicate preparedness to protect the economic minority who haven’t upgraded yet.
  • 2 weeks after 90% of hashrate signals: Taproot activates. Economic majority enforces, while miners protect the economic minority until they upgrade as well.
  • 2022 August 1: Entire economy has upgraded.

For explanations of the various parameters, see BIP 8.

  • name=taproot
    • Rationale: Already used in Bitcoin Core (for Signet and tests), no reason to change (BIP8’s “bipN” recommendation not applicable due to 2 Taproot BIPs)
  • bit=2

lockinontimeout preferences

This table summarizes wether each person is fine with setting lockinontimeout to true or false. source

This only concerns the first deployment, those in favor of a true should a first attempt to activate with false fail are counted as false here.

Some may be fine with both choices.
