this year, by what I have read the BIP's are ready to be implemented,
all that is needed is agreement of the community and developers and
of course wallet upgrades.
Pieter Wuille a core developer and the person behind TAPROOT,
has commented in the below thread although there are no specific dates
it will be merged, and discussion will start about how to activate it on the network,” he previously told The Block.
“If that too goes well, a release with the activation will be published, and if/when the conditions to activate it are met,
we'll be live.”
Wuille made clear that the exact timeline of the soft fork’s launch is now in the hands of the ecosystem.
“The later steps in this process are more up to the ecosystem than up to me or the other contributors,” he said.
