It would improve the security of #Bitcoin nodes if they automatically tracked BCH and other SHA256d PoW systems (not necessarily blockchains).

Then the node could have a true sense of the full global mining hashrate (which could be switched to an attack on Bitcoin at any time, even if not currently mining Bitcoin), and adjust its security predictions appropriately.

In case you missed my panels at the 2022 Miami #Bitcoin conference, the videos have been posted.

Anyone know any good lodging options in Miami for the #Bitcoin conference? 😅

#Bitcoin node stats fixed and fully restored. Historical data missing yesterday's data point due to the downtime (though the actual data to generate it exists, but I'm not planning to bother with it).

#Bitcoin node stats are broken, and I've run out of time to troubleshoot it tonight.

Problem is #Python's "pickle" is running out of memory (32-bit VM currently).
Any easy fixes until some day I get around to upgrading everything to 64-bit? :/

My review of BIP 119 (CHECKTEMPLATEVERIFY) proposal for #Bitcoin

tl;dr: I don't think CTV is ready yet (but probably close), and in any case definitely not worth reviving BIP 9 with its known flaws and vulnerability.

https://lists.linuxfoundation.org/pipermail/bitcoin-dev/2022-January/019776.html

In 2017, miners attempted to assert control over the #Bitcoin protocol, and failed thanks to #BIP148 / #UASF.

Later, exchanges attempted to assert control over the protocol, and failed again (#NO2X).

In 2021, developers attempted to assert control over the protocol by reverting to BIP9, and reintroducing and enforcing the miner veto, after the community came to consensus on BIP8.

It's not entirely clear if that failed or succeeded. But it should receive the same reaction: complete resistance.

#Bitcoin node stats update:

Figured out a way to detect and ignore some fake bots pretending to be lots of 0.16.0 nodes.

This brings the real node count down from ~70k to more like ~50k :(

(On the bright side, it also means Taproot enforcement is more like 62% - not great, but less terrible than before)

#Bitcoin Knots "Steel Rope" LTS 21.2.knots20210629 released! 🎉

Note: The LTS downloads are under "advanced"

https://bitcoinknots.org/?21.2?mastodon

FWIW, even if no company out there has the budget to fully fund my #Bitcoin development work, it would still be helpful if they could put me (& family) on some kind of health or dental insurance; or even cover expenses for a conference here or there...

#Bitcoin Knots 22.0.knots20211108 released! 🎉

Note: I also plan to release a Long-Term Support 21.2 in the near future, for users who prefer to minimise new-feature risks.
If you prefer to use a LTS branch, I recommend *not* upgrading to 22.x and waiting for 21.2 instead.

Bitcoiners should be careful not to let the failure of inflationary fiat result in #Bitcoin turning into nothing more than a new, non-inflationary* fiat.

This is a risk as people who don't necessarily care about decentralisation flock to Bitcoin for safety.

* for now (nothing prevents a non-inflationary fiat from adding inflation later)

Um, like 10 days until #Taproot activates for #Bitcoin ...
Only half the network is upgraded.

-.-

I also have evidence this cross-ban was NOT based on access IP address.

Considering that the user who baited me deleted his own account, and the unlinked Bitcoin Knots account was also banned, it seems likely this was a setup intentionally targeting my #Bitcoin work! :/

Adjusting for inflation, #Bitcoin today is at ~$12k pre-pandemic dollars.

So we're not actually at a new high yet.

I guess we need to break $100k for a real new high.

#Bitcoin Core @ubuntu PPA updated with 22.0.

(Sorry, it is no longer practical to support xenial/16.04LTS)

#Bitcoin Knots 0.21.1.knots20210629 released! 🎉

https://bitcoinknots.org/?20210629?mastodon

New @Ubuntu PPA ready for the #Bitcoin Core-based #Taproot client.

15 minutes until the #Bitcoin #Taproot meeting to ratify the final activation parameters!
