How works Bitcoin ? Full Guide

Bitcoin is a form of digital currency, created and held electronically. No one controls it. Bitcoins aren’t printed, like dollars or euros – they’re produced by people, and increasingly businesses, running computers all around the world, using software that solves mathematical problems.

However, bitcoin’s most important characteristic, and the thing that makes it different to conventional money, is that it is decentralized. No single institution controls the bitcoin network. This puts some people at ease because it means that a large bank can’t control their money.




A software developer called Satoshi Nakamoto proposed bitcoin, which was an electronic payment system based on mathematical proof. The idea was to produce a currency independent of any central authority, transferable electronically, more or less instantly, with very low transaction fees, bitcoin is created digitally, by a community of people that anyone can join. Bitcoins are ‘mined’, using computing power in a distributed network.

Bitcoins can be used to buy merchandise anonymously. In addition, international payments are easy and cheap because bitcoins are not tied to any country or subject to regulation. Small businesses may like them because there are no credit card fees. some people just buy bitcoins as an investment, hoping that they’ll go up in value

Since no bank is involved so when a person A transfers bitcoin to another person B, all the information is recorded in a public ledger(block), known as the Blockchain. The new block is added to a ledger at every 10 minutes. This ledger records all of the transactions that has taken place since the last ledger.

 For transferring bitcoin, person A have its own private key of his own wallet and gets the public key of person B wallet. Every bitcoin wallet can have one or many public keys that can be distributed to everyone but can have only one private key which only the owner of that wallet can know. Both the keys are very long(27-51 characters long) and it's impossible that two wallet have the same key combination.
