Bitcoin-Qt 0.8.3 patches a bug that could crash nodes
Picture mailing a letter stuffed with bricks the carrier still hauls. That's roughly what an attacker did to Bitcoin nodes in 2013, and the first fix had a bug of its own. Brief thread... 🧵👇

R to @daily_btc_lore: 4/7 - It stores the bloated version anyway, bytes and all. Send enough oversized messages and you can stuff a node's memory until it chokes and crashes. One attacker, an ordinary connection, and nodes falling off the network. The bug was catalogued as CVE-2013-4627.

R to @daily_btc_lore: 6/7 - While 0.8.3 reduced the original attack, message handling remained an area of active research. Further refinements to how nodes processed and validated incoming data continued through the rest of 2013 as edge cases were discovered.

R to @daily_btc_lore: 7/7 - Even a good fix can leave a narrower gap behind it. A reminder that the plumbing nobody thinks about has needed constant scrutiny since Bitcoin's earliest days.

More details emerge on Preston Pysh SIM swap
By mid-2023 telecom employees were taking bribes to hijack Bitcoin people's phone numbers. Preston Pysh watched an attacker take his anyway, right after he'd called in to stop it. Brief thread... 🧵👇

Low time preference is trainable | Daniel Batten
We talk about low time preference like it's something that the process of holding sound money does to us.
Hold Bitcoin, and you defer gratification by default. ie: don't spend today what could be worth more tomorrow.
This is true, holding Bitcoin does lower our time preference. It's also a skill you can build directly
Turns out that part has been measured across hundreds of studies.
The underlying skill is the ability to choose the larger reward later over the smaller one now. You train it with your own imagination.
When people picture a specific future in vivid detail, they discount it less and wait for the bigger reward more often.
Researchers call it "episodic future thinking". In randomized tests it measurably lowered how steeply people discounted the future.
If you make your future concrete enough, you will value it enough to wait for it.
One concrete example (of many): put friction between impulse and action, such as the "wait 10 minutes" rule before a purchase, snack, or reply to someone who just said something ignorant about Bitcoin on social media. You're not banning the thing. You are inserting a delay so the impulse passes and the deliberate choice gets a chance to take over. Over time, the pause becomes automatic.
Low time preference is a muscle that can be trained.
Baixa preferência temporal é treinável.
Falamos sobre baixa preferência temporal como se fosse algo que o processo de manter uma moeda sólida nos impusesse.
Ao investir em Bitcoin, você adia a gratificação por padrão. Ou seja: não gaste hoje o que pode valer mais amanhã.
É verdade, possuir Bitcoin diminui nossa preferência temporal. É também uma habilidade que você pode desenvolver diretamente.
Descobriu-se que essa parte foi medida em centenas de estudos.
A habilidade fundamental é a capacidade de escolher a recompensa maior no futuro em vez da menor no presente. Você a treina com a sua própria imaginação.
Quando as pessoas visualizam um futuro específico com detalhes vívidos, elas o desconsideram menos e esperam pela recompensa maior com mais frequência.
Os pesquisadores chamam isso de "pensamento episódico sobre o futuro". Em testes randomizados, isso reduziu consideravelmente a forma como as pessoas desconsideravam o futuro.
Se você concretizar suficientemente o seu futuro, você o valorizará o suficiente para esperar por ele.
Um exemplo concreto (entre muitos): crie um obstáculo entre o impulso e a ação, como a regra de "esperar 10 minutos" antes de uma compra, um lanche ou uma resposta a alguém que acabou de dizer algo ignorante sobre Bitcoin nas redes sociais. Você não está proibindo a ação em si. Você está inserindo um atraso para que o impulso passe e a escolha deliberada tenha a chance de prevalecer. Com o tempo, a pausa se torna automática.
A baixa preferência #temporal é uma habilidade que pode ser treinada.
