Phase 2 of my mission to bring more cats to bitcoin mastodon
Looks like ETH miners are pissed off.
"It isn't a surrender: Wright's army of attorneys can show up, but they'll find they've been sent to fight the ocean-- a force they can't even engage with but which could easily sweep them away."
Great quote from Greg Maxwell on bitcoincore.org taking down the bitcoin whitepaper, and how the rest of the community has taken to hosting copies.
"So, you want to get sued by a scammer?"
Greg Maxwell created a handy fill-in-the-blanks form letter for Craig Wright's lawyers, explaining how and why you're hosting the Bitcoin whitepaper:

Photos taken yesterday of the 458 new quarantine centres for COVID-19 that are being built in Shijiazhuang, China.
Currently they're claiming 180cases/day, out of a 1.4 billion population.
I personally don't trust that number.

"[ots-dev] Stamp/Beacon Trees for Secure, Precise, Trusted Timestamping and Clock Synchronization" - https://lists.opentimestamps.org/pipermail/ots-dev/2021-January/000106.html
tl;dr: My new merkle tree construction combines the precision of NTP, and the security of Roughtime. And unlike either, it can be scaled arbitrarily with untrusted servers.
Added to the #OpenTimestamps protocol, it'd allow one service to provide both high accuracy, trusted time, and trustless, low-accuracy, Bitcoin timestamps. A one-stop-shop for all your timing needs.

get the bitcoin whitepaper directly from the utxoset. This works on a pruned node:
seq 0 947 | (while read -r n; do bitcoin-cli gettxout 54e48e5f5c656b26c3bca14a8c95aa583d07ebe84dde3b7dd4a78f4e4186e713 $n | jq -r '.scriptPubKey.asm' | awk '{ print $2 $3 $4 }'; done) | tr -d '\n' | cut -c 17-368600 | xxd -r -p > bitcoin-test.pdf

Ok, zoomers.lol is now backed up every second day¹. The only thing not fully prime-time ready yet is the mail server (low rep, marked as spam). But since registration is with approval only (you better be a zoomer 😜) that's ok, I can manually confirm the email with 1 more click. So join if you want @nikcantmine, @xyse, @afilini …
¹Damn these media files are big … otherwise I'd do it more often, maybe I'll write something to deduplicate the data.

Re user's being confused, here's an example.
Even with control of no hashing power at all, you can very occasionally do double spends of confirmed transactions. You just have to be lucky enough for a stale block to get mined at the right time.
Stale blocks are pretty rare these days. I don't have stats handy. But looks like the % is something like 1 in 1000 blocks or less. So that'd be a sub 0.1% chance of success per attempt.
As an example, my OpenTimestamps server software waits 5 confirmations (by default). I'm not worried about losing money - the calendars are double-spending transactions to themselves. But the software frankly can't handle a double spend - you'd need to manually fix things in the calendar database.
So I just wait a few confirmations to make the probability of a double spend extremely low. So low that if one actually does happen, it's much more likely that Bitcoin itself broke in some way.
Unfortunately, Andreas falsely claiming a double spend did _not_ happen is dangerous: people have to realize that a single confirmation is not an absolute guarantee.
This case was ~$20, and looks like someone was just moving money between different wallets.
But if you're accepting a payment large enough that you can't risk even a very low chance of a double spend, you _do_ need to wait for multiple confirmations. Claiming otherwise could lead to people losing money.
As the Bitcoin whitepaper helpfully explains, the probability of a double spend attempt succeeding drops exponentially with the number of confirmations. One confirmation is extremely low, two is basically (extremely low)².
Full details: https://bitcoin.org/bitcoin.pdf
Andreas is incorrect here. A double spend _did_ happen.
Bitcoin's double-spend protection is probabilistic: after one confirmation, if the sender is attempting to double spend, the probability of success is extremely low. But it's still non-zero.
Lol, as I was leaving my apartment two cops were in the elevator, probably responding to a call. Neither were wearing masks, a legal requirement indoors here (fwiw, both were black, so no stereotypes here).
It's no wonder enforcement seems lax. Good on them for focusing on their real jobs.
(decent chance that was a domestic violence call - fairly common reason for calls in my building unfortunately)

On his first day in office, President Biden just essentially eliminated all single-sex spaces and sports in the United States. Every day more and more women are waking up to the dangers of these policies. This will be the moment that pushes us over the edge.

Probably the best allocation of productivity: Cobra seems much more interested than others in a legal fight over something that is at this point mostly symbolic. 😂
