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.

* 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)

* Note: Bit 2 is unaffected by ongoing miner ASICBoost false-bit-spam.
