What is the cumulative total number of hashes computed by all the bitcoin miners of the world since the beginning of times (i.e. genesis)?
My rough estimate: 3.84e28
Which is high enough that finding a hash with 24 leading zeros becomes quite likely.
(The smallest hash found so far is of block 756951 with 24 zeroes

My little pre-halving mining economics explainer:
The two most important numbers for mining economics -- total global hashrate and bitcoin price -- have changed drastically over the years. However, one measure, the 'hash price' is more stable. It estimates the daily revenue from a 1 TH/s mining capacity, in dollar terms. For most of the 5+ several years, it has been in the 0.06 -- 0.12 range (higher during peak bull market periods).
If hash price stays above 0.06, most miners will be OK. Currently it is 0.108, after the halving it will be, well, halved, to 0.054. I expect it will creep back to above 0.06 soon, by some mild drop in hashrate and some NgU.
Things balance out.

Disclaimer: this is not realistic, just a joke
The idea is to create a complete table with all 12-word BIP39 phrases, and next to each the correct last word, and the first default address. The generating software has to be validated once.
Then you download the PDF, print it out, and look up your own phrase, and find the correct last word and your first address.
I've generated the first and last pages, as a sample.
The only problem is that it takes a LOT of paper to print :DDD

It's relatively easy to create a random, 'raw' BIP39 passphrase, without using any computer, using a coin or a dice (e.g. 132 flips or throws with an unbiased item).
But can you compute the correct last word (it includes the checksum) on paper?
Can you derive a bitcoin address from the passphrase on paper? Or do you need to trust some chip, some CPU, with whatever inside?
I'm working on a solution...

Blockchain vs. Timechain
Shitcoins compromised the word blockchain big time. But that's a weak argument for me to switch to 'timechain'!
It's true that Satoshi used the timechain term as well, and it has to do with time a lot, but the word blockchain and block is just much more deeply rooted in bitcoin software. Period.
I don't give a fuck about shitcoin projects, and changing my ways as a reaction to their action is an acknowledgment. Switching to timechain seems like a woke thing. Blockchain it stays.

I share some thoughts on accepting bitcoin.
I like to pay for things in bitcoin, I always prefer the shops that accept bitcoin, I think circular economy is important. Yet I think it's not the most important goal.
Why?
Bitcoin is both a savings and a payment tool. As a savings tool, it has NO ALTERNATIVE for me. As a payment tool, I can use alternatives (even if I don't like them). I know that there are many groups of people who can't, but must of us can.
Therefore being a savings tool is a more important feature of bitcoin. We should work towards making bitcoin savings accessible to more and more people: educate and provide tools.
I also gave some thought on who is willing most to pay with bitcoin for things, and who is more likely to accept bitcoin.
The most likely to want to pay using bitcoin is someone who:
- knows about bitcoin
-- has some bitcoin savings
--- has some bitcoin income
The most likely to want to accept payments in bitcoin is someone who:
- knows about bitcoin
-- has some bitcoin savings, and wants to expand the savings
The basis for bitcoin circular economy are all the people who want to save in bitcoin. By working towards enabling more and more people to do so, the wish for bitcoin payments will grow organically (and mostly from the merchants' side).
Orangepilling your corner coffeeshop or gym is nice, but it I think it's more important to orange pill your friends to buy bitcoin. The rest will follow, gradually then suddenly.

I agree that a ~9x increase in transaction throughput is _not_ a scaling solution, and Liquid is not a Lightning replacement or competitor. But it does make sense to take use of the lower fees of Liquid (there can be a 1000x difference).
Today it makes sense to keep long-term holdings on chain, middle-term mid sum amounts on Liquid, and short term spending on Lightning.
I would like to see expansion of direct Liquid-to-Lightning solutions, I think these would actually be beneficial for Lightning! When on chain fees are high, many people simply will not open new channels, and will gravitate towards custodial Lightning solutions. If Liquid-backed channels were an option in wallets, that would be an additional option for fee-sensitive users. Atomic Liquid-to-LN swaps exists and are convenient, but directly Liquid-based LN solutions are not mainstream (if exist at all).
On a final note, it seems that saturation of the Liquid side-chain is far in the future. When that happens, I speculate that the federation may decide to increase the capacity. An increase by a small factor will not solve scaling, but may be beneficial for the middle-ground usage of Liquid. The point is that it is much easier and less dangerous to change the blocksize in Liquid than on the main chain.

I'm sure eventually some better solutions will be developed, but it's the best we have.
