What is Bitcoin

Bitcoin is a digital currency that was created in 2009 by an unknown person or group using the pseudonym “Satoshi Nakamoto”. Unlike traditional currencies such as the US dollar or the euro, Bitcoin does not have physical coins or banknotes. Instead, Bitcoin transactions are typically executed in a decentralized network of computers known as the blockchain.

The blockchain of Bitcoin offers numerous advantages, such as the ability to store transactions and other data. In addition, the use of second-layer technologies such as Lightning enables faster and cheaper transactions. The data is grouped into blocks, encrypted cryptographically, and stored in a decentralized manner, making the Bitcoin network the safest and least censored decentralized data storage in the world.

One of the most important features of Bitcoin is its limited quantity. There will never be more than 21 million Bitcoins, which means that it is not easy to create new Bitcoins. This makes Bitcoin a deflationary currency, where demand exceeds supply, which tends to increase its value.

Bitcoin is often referred to as “digital gold” because it possesses similar characteristics to gold, but is much easier to trade and transfer due to its digital nature. It can be used as a means of payment for goods and services, as well as a hedge against inflation and as an investment.

Since Bitcoin is a decentralized network, it is not controlled by any government or institution. This means that there is no central authority that regulates the value or availability of Bitcoin. This makes Bitcoin a very volatile asset that is subject to rapid fluctuations but also can protect against confiscation.

Overall, Bitcoin offers an alternative form of traditional government money that allows for secure and cost-effective transactions without relying on a central authority.

Bitcoin Whitepaper

The Bitcoin Whitepaper was published in 2008 by a person or group named Satoshi Nakamoto and introduces the concept of Bitcoin, a decentralized digital currency that operates without central control or intermediation. The Whitepaper is the founding document of Bitcoin and describes the technical details and operation of this revolutionary technology.

Semantic tags

These tags are used to structure HTML code.

<header>
The header contains the most important information of a page, such as the title, navigation, and logo.
        <body>
            <header>
                This is the header section of the page
            </header>
            <main></main>
            <footer></footer>
        </body>
      
<main>
The main contains the main content of a page.
        <body>
            <header></header>

Introduction to JSON

JSON is a format for exchanging information between different programs. It’s like a list of things, where each thing has a name and a value.

Object

Imagine you have an object. An object consists of curly braces {} and inside it, there are names and values separated by commas. For example, you can have an object that contains a person’s name and age:

{
  "name": "Jeffey",
  "age": 34
}

Array

An array is like a list. It is written inside square brackets [] and contains values that are also separated by commas. Here is an example of an array of fruit:

["black", "red", "yellow"]

The values in JSON can be strings (text), numbers, boolean values (like “true” or “false”), other objects, arrays, or even nothing (null).

Strings are enclosed in double quotes ". For example, "Hello" is a string.

Numbers, boolean values, and null are written without quotes. For example, 42 is a number, and true is the boolean value “true”.

Why JSON?

JSON is easy to read and supported by many programming languages. It is used for exchanging information between programs and is a popular choice for data communication.

Halving Blocktime

This is a blocktime calculator that aims to display a more readable version of the block time. Simply input the traditional block time, e.g., 714778, and the halving time will be displayed.
