At least once a week, somebody on the street tries to sell me cannabis. I'm sure it's because of my long hair (and maybe my beard and frequent sandal wearing). What's interesting to me is how many unique people have made me this offer. I'm wondering if there's an algorithm I can use to estimate the population of local people with a pot-selling side hustle based on the frequency of my encounters, the number of hours I spend in public, and the local population density.
Nice discussion here on privacy challenges in Bitcoin by @pwuille
Pieter's answer is well worth a read, and thanks to @bitcoinoptech for surfacing this in their newsletter.
@stevenroose @udevnull @giacomozucco I don't understand what you're saying. Do you know that BIP8 LOT=true users require a mandatory signaling period? (The specifics of that were changed a few months ago, separating it into a distinct period.) https://github.com/bitcoin/bips/blob/master/bip-0008.mediawiki#Mandatory_signalling

- notes changes to popular Bitcoin infrastructure software
@kalle @jb55 @pete Yeah, it did use OP_RETURN. https://github.com/petertodd/dust-b-gone/blob/master/dust-b-gone.py
@jb55 I think @pete had a tool that would spend your dust to a particular output signed with SIGHASH_NONE (or something) so that multiple dust spends by different people could be aggregated together, splitting the cost of the output. For a 100,000 vbyte tx assuming all inputs are P2WPKH, you can split the 31 vbytes of output 1,475 ways for a relative cost of 0.02 vbytes per input---which is pretty close to zero.
Still, I agree with your point in principle.
You mention the fingerprinting risk, but at the time it was implemented, Bitcoin Core was also one of the only wallets using anti-fee-sniping, which is an even stronger fingerprint. Now there are a few other wallets doing that (including C-Lightning, which also low-R grinds).
21 was the first company to do anything serious with micropayment channels before LN, and I'm proud of some of the work I did on that. But, yeah, the company never had much of a public impact.
@stevenroose @michaelfolkson the "21 Bitcoin Computer" was their first public product. Then they released the 21.co marketplace for bitcoin-payable APIs. Then they released the "21 Earn" paid email service, eventually renaming themselves to Earn.com and being acquired by Coinbase to become Coinbase Earn, a platform for paying people to learn about scamcoins.
Source: I worked there from 3 days before the launch of the computer to a couple months before renaming to Earn.com. :-)
Bitcoin Consensus and Solidarity:
I deleted a much more technical post, because it derives from this base idea: that consensus is vital but unverifiable. Our only defense is to have our signalling be open, broadly-based and sustained.
The latest http://mempool.space with #signet support is the nicest way to explore your transactions when testing #JoinMarket (a few clicks to setup with #JoininBox).

@raucao yeah, the August 2019 relicense from GPLv3 to "Business Software License" that forbids you from using their software to compete with them.
I didn't know that happened; I've been using ZT since 2015 and never rechecked the license on subsequent downloads.
That doesn't make me happy about it, though. If there were more four-engine planes flying to and from HNL, I'd probably prefer to book them, but they're rare.
12,000 meters is only ~33% higher than Mt. Everest where people are on the edge of breathing, so I assume jet fuel and lots of other things can still burn.
