Taproot activation megathread

An activation mechanism called “Speedy Trial” has just started on the 1st of May. Its goal is to give miners an opportunity to coordinate a quick activation of the Taproot update.

The gist of it is: miners are given a three months time period to signal for Taproot activation. Within those three months, there are six sub-phases (each consists of 2016 blocks, aka ~2 weeks). As soon as there are 90% of blocks signalling for Taproot within any of those six sub-phases, Taproot activation will be locked in. The actual new protocol rules will then be enforced starting from block height 709,632, which is expected to be mined in November.

We are currently in the first of those six sub-phases, and Taproot activation will not happen in this one, as miners need time to upgrade their equipment (this is expected, as the software update with Taproot activation mechanism was only released a few days ago). But already now (as of 4th of May) there is roughly ~50% of mining power that has updated and started signalling for Taproot.

You can watch the currently signalling blocks/mining pools here:

Currently signalling for Taproot:

  • SlushPool (~3% mining power)
  • AntPool (~18%)
  • F2Pool (~18%)
  • 1THash (~4%)
  • Foundry (~4%)
  • Poolin (~10%)

Keep in mind, actual hashrate is always unknown and numbers above are an estimation only, based on observations of the recent blocks, which is always subject to variance.

What is Taproot?

Summary

  • If you are a singlesig HODL-only Bitcoin user, Taproot will not affect you positively or negatively. Importantly: Taproot does no harm!

  • If you use or intend to use multisig, Taproot will be a positive for you.

  • If you transact onchain regularly using typical P2PKH/P2WPKH addresses, you get a minor reduction in feerates since multisig users will likely switch to Taproot to get smaller tx sizes, freeing up blockspace for yours.

  • If you are using multiparticipant setups for special systems of trade, Taproot will be a positive for you. Remember: Lightning channels are multipartiicpiant setups for special systems of lightning-fast offchain trades!
