- Update on Bounty Program & Feedback (10 Min)
- Feedback Recap (20 Min)
- In this section we'll review any recent feedback or review of CTV.
To expedite the meeting, a summary is provided below of the main
feedback received since the last meeting and responses to them so that the
time allotted may be devoted to follow up questions.
- Luke Dashjr's feedback
- thread:
https://lists.linuxfoundation.org/pipermail/bitcoin-dev/2022-January/019776.html
- summary:
Dashjr notes that while CTV is not done, it may be nearly done.
Dashjr requests that some applications be made BIP-quality before
proceeding, amongst other smaller feedbacks.
Dashjr also expresses his concerns about activation logic.
Respondents debated the activation logic, and there was a general
sentiment to keep the discussion of CTV and activation logic somewhat
separate, as Activation is a general concern pertaining to all upgrades and
not CTV in particular.
Rubin responded asking if BIP-quality is required or if examples
like those in rubin.io/advent21 suffice.
- James O'Beirne's feedback
- Github Link:
https://github.com/bitcoin/bitcoin/pull/21702#pullrequestreview-859718084
- summary:
O'Beirne tests the reindexing performance with the CTV patches and
finds a minor performance regression due to the cache precomputations.
Rubin responds with patches for an improved caching strategy that
precomputes the CTV hashes only when they are used, but it is a little more
complex to review.
Rubin also points out that the tested range is not representative
of "current" blocks which have a higher proportion of segwit.
- Peter Todd's Feedback
- thread:
https://lists.linuxfoundation.org/pipermail/bitcoin-dev/2022-January/019738.html
- response:
https://lists.linuxfoundation.org/pipermail/bitcoin-dev/2022-January/019739.html
- summary:
Todd reviewed the BIP and an (outdated) implementation and was
disappointed to find that the testing was insufficient, the analysis of
validation resources was insufficient, and the quality of proof of concept
applications was insufficient.
Rubin responded by pointing Todd to the most up to date
implementation which has more tests, updated the link in the BIP to the PR,
updated the BIP to describe resource usage, and asked what the bar is
expected to be for applications.
Rubin further responded with an analysis of current congested
mempool behavior here:

.
Todd is yet to respond.
