My friends and family are tired of hearing me talk about decentralization. Now it's your turn.
Rascunho Livro v01
Racunho Livro Bitcoin - Matheus Bombig Who is this book for? In 2017 I did something I'm not very proud of: I fell in love with blockchain as a technology! The first time I heard about Bitcoin was back in 2013 when I was still attending investment and finance forums. But at the time I didn't even care, after all, it seemed like something very crazy and far from my reality. I barely had an international credit card at the time, let alone buying a digital asset. However, in 2016 I had...

Bitcoin - Introduction v01
v01 Hash Hashing is a process that can be likened to generating a unique fingerprint for data. Just as our fingerprints act as unique identifiers, a hash function produces a fixed-size output for any given input, making it a one-of-a-kind representation for that data. Hashing is widely used in computer security, especially in securing logins and passwords, as it prevents plain-text passwords from being exposed during transmission over the internet. Let's explore the key features of hashi...

Hash: Data Fingerprint [EN/PT]
“Any sufficiently advanced technology is indistinguishable from magic.” In today's fast-paced world, technology has become so ingrained in our daily lives that we often take it for granted. We interact with an array of digital devices and applications on a daily basis, with most of their inner workings remaining hidden from us, quietly powering our digital experiences. These under-the-hood technologies operate seamlessly, shaping our interactions without us even realizing their existence...

Previous attempts to create a decentralized currency before Bitcoin [EN/PT]
[EN] Bitcoin may be the most well-known example of a decentralized digital currency, but it was by no means the first attempt at creating one. ** **For years prior to the creation of Bitcoin, cypherpunks, activists, and computer scientists had been working on projects aimed at creating a digital currency that would be immune to the coercive power of the state and financial institutions.

Double Spending Attacks [EN/PT]
While double spending is unlikely to occur, it is not impossible. There are actually three types of attack that in theory could cause double spending. ** **Finney Attack** ** This attack is named after Hal Finney. Hal Finney was one of the early Bitcoin contributors and the first person ever to receive Bitcoin from Satoshi Nakamoto himself. Finney explained that a double spending attack could happen in three steps. ** **First, the attacker performs a transaction in which he sends his coin to ...
