Really worth a read on current developments in Bitcoin in China:

"Once both sides agree on a price, the buyer will use a separate payments platform -- operated by their bank or a fintech company like Ant Group Co. -- to send yuan to the seller. The digital coins, usually held in escrow by the OTC platform until the yuan payment clears, are then transferred to the buyer. Chinese regulators often have no way to connect one step of the transaction to the other."

New release of Electrum Personal Server. Fixed issue with lag for large mempools, most users would just disable the mempool histogram for large mempools, with this update that is no longer an issue. Also, now slightly easier to run with automating tools like systemd. Connect your Electrum wallet to your own full node today!

Joinmarket does 650 BTC or ~ 38M USD volume in one day...

... is the clickbait statistic I would use if I didn't know it's pretty stupid to measure like that 😂

(how? first:
h/t @openoms for using the ` -j` script I recently mentioned on recent blocks - from 682603 to 682795, roughly 1.3 days' worth). From earlier experiments, this is higher than average, but not stupidly so. Also h/t @kristapsk for his transaction parser script for easier reading the output. Data: ...(1/n)

I will run...

Releasing a client with a name "Bitcoin Core 0.21.0-based Taproot Client 0.1" is a scammer trick. It's not Bitcoin Core.

I suppose if you can't convince people with reason, trick them with dishonesty.

I just added a section to the bitcoin wiki explaining how address reuse can also harm censorship resistance as well a privacy:

Time preference question: Suppose you sent coins to a timelocked address (made with OP_CLTV). How many years/decades would the coins have to be locked up for so that to you it's just the same thing as just destroying them?

Just released 0.8.2 of Joinmarket. This is to be considered an urgent privacy bugfix for takers; see the release notes for details:

I'll write more about this bug and what happened, shortly.

BIP8 activation is dead because we can't agree on the value of LOT. We need another solution. That's the topic of my latest mailing list post - Making the case for flag day activation of taproot.

RT @martybent
.@chris_belcher_ took to the bitcoin-dev mailing list to announce progress on his CoinSwap implementation. Check out Teleport Transactions. Support the cause. And get us closer to borking chain analysis heuristics that reduce the privacy of bitcoiners.

Takeaways from the #taproot activation discussion:
1. Unanimous support for BIP8. RIP BIP 9.
2. Overwhelming consensus that 1yr is correct timeout value (it's actually defined in blocks, so 26x2016 or maybe 87600).
3. Majority consensus for lockin false, though @lukedashjr strongly opposed.
4. No decision I could see on start time, but 2 months was done for segwit, and that didn't seem too objectionable.
