Serious education exists.
For devs programs, search for Vinteum, Chaincode Labs, Btrust Builders, Bitshala, Liberia de Satoshi. How to get funded is one of the things we talk in the programs.
Also, I have a regular Bitcoin course for CS and engineering programs at the Univ. of Brasília and I'm helping update the MIT course.
So, for your question of how to survive, we have undergrads that went straight to a bitcoin grant or job, we have guys that saved from their 9 to 5 job and used that to finance themselves until they've built enough proof of work to get funded, and we have guys that do as a side job while they build enough proof of work to quit.
Could be better, but funding is out there and tends to improve. It just is not actively advertising as in a regular company. Once you build a track record of smaller contributions, you'll find a way to reach a decent grant.

Well, you have been in this space as a serious contributors for way longer, maybe I'll evolve to that direction too.
Think out loud, I agree that decentralized consensus and it's mechanics are the genius bits that tie everything together.
I'm interacting to a lot of people in two contexts. First, with engineering and cs students at the University. Second, with devs attending the educational program we run in Brazil.
In both contexts, I feel all of them can't grasp a conceptual view of consensus and how it influences the various parts of the protocol. My hypothesis is that they don't understand that the transactions establish a language in which we talk about transfer of ownership.
Personal evidence (from this small universe of interactions) is that they keep using analogies and metaphors to talk about consensus, even when called to talk about it terms of the transactions (which are the fundamental messages we are propagating and validating).
Thanks for sharing your view (and please do more) in this discussion and feel free to comment, disagree and provoke in the repo of the project. Developing a university course in the open doesn't seem common, I wanted to experiment with that too.

I'm more inclined to say that Part 3 is the most important (transaction semantics) for other protocols development and that's what's on my mind right now.
Part 5 would be the foundation of consensus. Thinking out loud, maybe I'm taking consensus for granted during the previous parts.
In the overview of Part 1, I plan to explain all the mechanics, including distributed consensus, but without going into the details. Indeed, I feel it didn't work well last year. Maybe I should consider a lecture dedicated to consensus.
Thanks.

Sim. Esse item em específico estou pensando em reformular. Minha ideia inicial era trazer aí as codificações das chaves e das assinaturas (uncompressed, compressed, sec, wif, etc) já que são informações que a carteira lida na hora de construir e assinar as transações. A parte de cripto eu pensei em deixar mais teórica.
Mas não estou totalmente decidido o que seria a melhor pedagogia. Ano passado falei disso na parte de cripto e senti que a turma boiou.

Next week I'm attending @npub1ze9…3pxq to talk about the gap between Bitcoin and the Academia.
They say that to change academia is like moving a graveyard: you can't count with their inhabitants. This is true in so many aspects. Yet, I believe both communities could benefit from more interaction.
For academia, Bitcoin is a huge source of problems in the frontier of knowledge that require strong science. Also, it's an opportunity for working on real-world projects that will impact the lives of millions for good. Contributing to open source is an obvious way of returning the humongous investment all countries make in higher education in a meaningful way.
On the Bitcoin side, having some of the smartest brains around has the potential to accelerate the pace of innovation and security in many protocols.
This is not to say that Bitcoin needs the academic community, quite the contrary. If we, scholars, don't get out of the ivory tower and embrace the self-organizingethos of Bitcoin and related technologies, we will be obliterated by reality.

"Wallet distribution" probably works well to convey to the general public the idea of funds dynamics that you seem to be heading to.
"Address distribution" is probably more technically correct, but does it speak well to your intended audience (without having to explain too much)?
Thought of "Balance distribution" (which I personally like) or "Funds distribution", those might work too.

One of the main drawbacks of building a trustless network is that people naively come to believe that trust is a bad thing.
Bitcoin is trustless in a very strict sense, of not requiring an authority to clear transactions.
Yet, you (probably) still trust:
1. ECC is not broken and will not break in the foreseeable future.
2. SHA256 and Ripemd160 will not break either.
3. The node software you run is not compromised.
4. The wallet you use is not compromised.
5. The OS you run is not compromised.
6. The many pieces of hardware you use are not compromised.
7. Your connection to other nodes is not compromised.
Most of all, you trust other people will want to use Bitcoin, otherwise it's worthless and a waste of time.
Even Satoshi trusted in the community to keep developing Bitcoin: "I’ve moved on to other things. It’s in good hands with Gavin and everyone."
You just can't verify everything yourself, you have to start from somewhere and built upon.
Don't be a trustless lunatic.

2024-10-14 19:20:34 UTC

Bitcoin misconception: all nodes maintain a copy of the same blockchain.
In reality: most nodes will be able to synchronize to the exact same blockchain, but some won't. E.g. pre-segwit nodes don't see the same data as segwit aware nodes, so they can't maintain the same data.
Yet, this won't cause a fork on the network because what matters is not to have the same blockchain. What matters is to agree about the UTXO set state at all times.

Gold was an excellent money, it can hold value across time and space.
But it has a fatal flaw: holding value a cross scale was difficult. Indeed, this is a problem with all physical commodities.
If it is highly valuable, small value transactions that constitute the day to day routine of most people are hard to make. If it has low value, large scale transactions suffer and add friction to specialization and economic development.
We solved this problem long ago with banks and gold certificates. But it was too easy for governments to corrupt the system and the people lost control of their money.
Which is unfortunate, fiat looks convenient for small scale transactions, but it is made a hassle for large scale. It is not transferable across borders, and it doesn't hold value across time.
It doesn't work for savers and innovators. It barely works for short term thinking people that conform to the norm. It only works to keep people under control.
That's why it won't last forever.

2024-09-25 00:38:26 UTC

My most recent paper addresses the excellent book Better Money: Gold, Fiat, Or Bitcoin?, by Lawrence White.
Tl;dr for the bitcoiners around:
- you probably don't understand the economic weaknesses of bitcoin, it's not superior to gold in all aspects.
Tl;dr for the bitcoin skepticals:
- you probably don't understand money enough, it's inferior to gold and bitcoin in virtually all aspects.
Unfortunately, what drives adoption of new technology is not technical superiority, but the increasing friction on the incumbent system. For fiat, friction is called inflation.

"Professor: If You Read To Your Kids, You’re ‘Unfairly Disadvantaging’ Others"
Professor of Philosophy: “I don’t think parents reading their children bedtime stories should constantly have in their minds the way that they are unfairly disadvantaging other people’s children, but I think they should have that thought occasionally,”
But he reveals himself, it's only a perverse anticapitalist mindset: “we could prevent elite private schooling without any real hit to elite family relationships.”
I truly understand a professor who don't have to care about the real world saying such nonsense. I'm a professor myself, I know what I'm talking about.
But I can't swallow people doubting themselves because of pompous titles. This is how the reporter finishes her article.
"In general, I tend to believe that focusing on improving things for the less fortunate is a better way to advance our society than purposely making things worse for those who have more, but what do I know? After all, it’s not like I’m a philosopher or anything."
Come on, you see something is wrong and you doubt yourself instead of questioning it? This is just an anecdote that shows why traditional media is so doomed.

Bitcoin is a debit card?
That's how a dear colleague is trying to argue against my position that Bitcoin can become money someday.
A debit card is just a messaging system, a kind of voucher that is redeemable for the underlying currency, which is Reais or Dollars, or any modern fiat.
There existed this kind of stuff during the gold standard (not electronic, but in actual paper and in balance sheets) and it is estimated that it was more prevalent than barter and gold itself, coins being reserved for transactions with strangers, and bank notes for distant fairs and for large transactions.
I highly disagree that Bitcoin is a debit card, but I'm curious about the rationale behind this position. Bitcoin is a messaging system in its core, just like a debit or credit card system, indeed. But it is not debit from someone else like in a debit (or credit) card system, it is the asset itself and the underlying "physical" phenomenon associated with this asset is being able to send new messages in this system.
Yes, it looks like fiat in the sense it's not redeemable for an underlying commodity, but it is intrinsically different from fiat for it is an entitlement for sending messages in a real system that (some) people decided (in the market) to value.
Lawrence White, in Better Money, argues that the difference in nature between fiat and Bitcoin is government coercion. I understand there's more to it.
You may argue that Bitcoin is not money since it is not widely accepted as a medium of exchange. I'll agree with that. But for something to become money, it has to not be money before (like gold, silver, and fiat). Also, there's no accepted theory for how something becomes money.
So, we may be witnessing the monetization of this thing (or not, who knows?). I'm betting in the monetization of this thing for more than economic reasons. I may be wrong, time will tell.

I recently finished reading Better Money: Gold, Fiat, or Bitcoin?, by Lawrence White. While I’m preparing a proper academic review, maybe someone will appreciate some of the book’s main points.
- Strong historical material explaining different implementations of money.
- Quite basic supply-and-demand methodology for comparing gold, fiat, and Bitcoin. Yet, the common ground makes for a conscientious analysis, especially for pointing that Bitcoin’s purchasing power volatility is inherent to the system from an economic perspective.
Take aways:
1. “A gold standard has the advantage that the global stock supply curve for monetary gold is non-vertical in the short run and nearly horizontal in the long run, providing responses in the quantity that stabilize the purchasing power of gold, but the disadvantage that the supply curve can occasionally shift.”
2. “A fiat standard has the potential advantage that its supply can be deliberately managed to stabilize the price level both in the short run and in the long run, but the disadvantage that has seldom been managed that way in practice, due to the incentives that accompany government control over the quantity of money.”
3. “A Bitcoin standard has the advantage that the Bitcoin supply curve does not shift, but the disadvantage that the supply curve is vertical in both the short run and the long run, implying unstable purchasing power in the face of money demand variations.”
White is skeptical about a Bitcoin standard because of purchasing power volatility. He argues that people preferred stable monies over time and that the costs associated are high.
“My prediction is that BTC is unlikely to become a commonly used medium of exchange for the same reason, namely that its purchasing-power risk and transaction costs make it unattractive to use as a medium of exchange.”
My main critique: fiat money was created by governments (White explains the mechanics of this movement) and they have a higher cost over society in the form of inflation (as he argues with historical evidence). It was done because of political reasons, not economical. I would not overlook people coming to accept higher purchasing power volatility of an eventual Bitcoin standard if governments stay in the last century’s track of increasingly assault over the institution of private property.
Does it worth reading?
Definitely, it will expand your knowledge about monetary systems and understand some fair critiques about Bitcoin.

O máximo possível. O tempo é o fator mais importante é o seu efeito é exponencial, tanto para ajudar quanto para atrapalhar.
Quer dizer, se você começar na metade do caminho, precisa poupar mais que o dobro a cada mês para chegar no mesmo resultado.
Eu comecei com 33 anos e procuro poupar cerca de 30% da minha renda todos os meses, incluindo os extras que eventualmente consigo (sim, 30% é muito e exige muita força de vontade). Depois de 6 anos não posso reclamar da tranquilidade que isso me dá, mas creio que vão ainda uns bons 15 anos pra eu cogitar viver de renda.

Alterno entre Primal e Damus pra entender qual seria o mais bem acabado.

Nossa, isso aí vai expor muito o Xandão. Vai aumentar a temperatura, mas não creio que vá resultar em alguma ação mais concreta contra ele. Pelo menos não no curto prazo.

Have you watched Game of Thrones?
It's a fictional representation of what happened in all times and places: small folk have nothing to do and, apart from making jokes, care very little for the quarrels and plots of rulers.
Rulers are capable of turning its people outlaws and impose unfair punishment over them for supposed crimes they didn't participate.
But after sufficient time, what happens?
Either bloodier plots or a war.

Well, I wasn't expecting nor hoping this would mature so well when I drew it in 2022.

Who pays for Bitcoin block rewards?
Bitcoin hodlers do.
The payment is hidden by the more apparent appreciation in price when compared to the unit of account (e.g., dollars), but nonetheless real.
By contrast to a world in which block rewards are zero, and so miners receive only fees, block rewards expand the pool of BTC in circulation, diluting the purchasing power of each existing BTC unit (holding real demand constant).

I would like to remember that the technologically incompetent decisions we are witnessing in Brazil come from the same court that manages our election system.

Politics under a democracy involve a curious psychology.
You trade your incapacity to control market agents that can’t coerce you for the incapacity to control the political agents that can coerce you.

So far, Damus looks better, Primal seems to work better. 🤔
