What is bitcoin?

Bitcoin is the world’s first successful decentralized cryptocurrency and payment system, launched in 2009 by a mysterious creator known only as Satoshi Nakamoto.

Bitcoin can be divided into smaller units known as satoshis, and used for payments. the price of a single bitcoin has increased considerably since its begining – from less than a cent to tens of thousands of dollars. When discussed as a market asset, bitcoin is represented by the symbol BTC.

The term “decentralized” is used often when discussing cryptocurrency, and simply means something that is widely distributed, centralized location or controlling authority. In the case of bitcoin, and indeed many other cryptocurrencies, the technology and infrastructure that govern the creation, supply, and security of it doesn’t depend on centralized entities, like banks and governments, to manage it.

Instead, Bitcoin is designed in such a way that users can exchange value with one another directly through a peer-to-peer network; a type of network where all users have equal power and are connected directly to each other without a central server acting in the middle. This allows data to be shared and stored, or bitcoin payments to be sent and received between parties.

anyone in the world with an internet connection and a device that can connect to it can participate without restriction. It’s also open-source, meaning anyone can view or share the source code Bitcoin was built upon.

Perhaps the easiest way to understand bitcoin is to think of it like the internet for money. The internet is purely digital, no single person owns or controls it, it’s borderless (meaning anyone with electricity and a device can connect to it), it runs 24/7, and people who use it can easily share data between one another. Now imagine if there was an ‘internet currency’ where everyone who used the internet could help to secure it, issue it and pay each other directly with it without having to involve a bank. That’s what bitcoin essentially is.

How does bitcoin work?

It’s important to understand there are three separate aspects to Bitcoin:

    • The Bitcoin network.

    • The cryptocurrency of the Bitcoin network, called bitcoin BTC.

    • The Bitcoin blockchain.

Bitcoin runs on a peer-to-peer network which means individuals who want to exchange bitcoin with others on the network. Users can choose to connect their computer directly to this network and download its public ledger in which all the historical bitcoin transactions are recorded.

This public ledger known as “blockchain,” also referred to as distributed ledger technology. Blockchain is what allows cryptocurrency transactions to be verified, stored and ordered in a secured way. security is vitally important for a payment system that relies on no trust.

Whenever new transactions are confirmed and added to blockchain, the network updates every user’s copy of the ledger. Think of it as an open Google document that updates automatically when anyone with access edits its content.

How is bitcoin created?

The Bitcoin network automatically releases recently formed bitcoin to miners when they find and add new blocks to the blockchain. The total force of bitcoin has a cap of 21 million coins, meaning once the number of coins in rotation reaches 21 million, the protocol will stop minting new coins. In a way, Bitcoin mining doubles as both the sale confirmation and the bitcoin allocation process( until all the coins are booby-trapped, also it’ll only serve as the sale confirmation process.)

The Bitcoin network uses a coin distribution strategy known as “ bitcoin halving ” that ensures the quantum of bitcoin distributed to miners reduces over time. By gradationally dwindling the force of new bitcoin entering rotation, the idea is it’ll help support the asset’s price( grounded on the abecedarian principles of force and demand.)
A bitcoin halving( occasionally called a “ halvenings ”) happens every,000 blocks or roughly four times. When the bitcoin protocol first launched in 2009, each successful miner entered 50 bitcoin( BTC) as a block price. Fast forward to 2021 Block prices are now6.25 BTC, a reduction from12.5 BTC previous to the bitcoin halving in May 2020.

A bitcoin wallet is a software program that runs on a computer or a devoted device that provides the functionality needed to secure, shoot and admit bitcoin. Counterintuitively, the bitcoin itself isn’t stored in a portmanteau. rather, the portmanteau secures the cryptographic keys — basically a veritably technical type of word — that proves the power of a specific quantum of bitcoin on the Bitcoin network.

Anytime a bitcoin sale is executed, power of the bitcoin transfers from the sender to the philanthropist, with the network designating the philanthropist’s keys as the new “ word ” for penetrating the bitcoin.
Bitcoin uses a system called public- crucial cryptography( PKC) to save the integrity of its blockchain. Firstly used to cipher and decipher dispatches, PKC is now generally used on blockchains to secure deals. This system allows only individualities with the right set of keys to pierce specific coins.

There are two types of keys needed to enjoy and execute bitcoin deals A private key and a public key. Both keys are strings of aimlessly generated alphanumeric characters used to cipher and decipher deals. On the bitcoin network, PKC tools one- way fine functions that are easy to break in one way and nearly insolvable to reverse.

The blockchain uses the one- way fine algorithm to produce a public key from the private key. With this, it’s virtually insolvable to regenerate the private key from the public key, meaning you ’d more not lose your keys( or forget your word to pierce them). Also, you’ll admit a public address, which is simply the hashed or shorter form of your public key.
This address functions also to a house address and is participated to admit bitcoin. On the other hand, the private key must be kept hidden from prying eyes, just as your disbenefit card’s Leg is meant for your eyes alone.

To execute deals, you’re needed to use your private key and public key to encrypt and subscribe your Bitcoin deals. Also, you have to include the public address of the philanthropist. With this, only the philanthropist with the right private key can unleash or claim the transferred bitcoin.
