What is Bitcoin

Bitcoin is a cryptocurrency or digital currency that knuckles under the principle of cryptography for regulation and generation of units of currency. The asset fell under the scope of cryptocurrency and was the first and most valuable among them all. That’s frequently called decentralized digital money.

Bitcoin is also very different from traditional currencies. Unlike euro or dollar, Bitcoin isn’t backed by any government, since it’s a fully decentralized funds form.

Bitcoin isn’t linked to any central banking system or issuing authority, and that’s a big part of its appeal — instead of being swallowed into a system that’s often sullied by human greed and manipulation. This currency exists in an online world driven by mathematics and cryptography protocols.

Bitcoin Basics

Bitcoin is the first crypto asset and the first successful implementation of a distributed cryptocurrency, partially described in 1998 by Wei Dai on the cypherpunks mailing list. Building upon the notion that money is an object or any record, accepted as payment for goods and services and repayment of debts in a given country or socio-economic context, Bitcoin is designed around the idea of using cryptography to control the creation and transfer of money, rather than relying on central authorities.

Bitcoin does not require any ID to use. Making it suitable for the unbanked, the privacy-conscious, computers or people in areas with poor financial infrastructure.

A bitcoin transaction is propagated nearly instantly in the network and is usually confirmed in a couple of minutes. Since they run in a global network of computers, they are completely indifferent of your physical location.

Bitcoin funds are locked in a public key cryptography system. Only the owner of the private key can send and use the cryptocurrency. Strong cryptography and the encrypted digits make it impossible to be hacked.

The laws of supply and demand determine Bitcoin’s price. Because the total amount is limited to 21 million bitcoins, as more people use Bitcoin the increased demand, combined with the fixed supply, will force the price to go up. Since the number of people using Bitcoin in the world is still relatively small, the price of Bitcoin in terms of traditional currency can fluctuate significantly on a daily basis but will continue to increase as more people start to use it.

Bitcoin as the first pan-global currency (or commodity) that can be used by people all over the world as a medium of exchange without involving governments, the cryptocurrency will continue to attract interest and resistance.

Bitcoin Development History

The second half of 2008 – from this time, the history of Bitcoin begins its countdown. In those days, an anonym or a group of people, hiding under the pseudonym Satoshi Nakamoto, published a document describing the first cryptocurrency, releasing a client to work with the network and generating a genesis block for which 50 BTC reward was charged. So the world first heard about Bitcoin.

We can not say that the history of the emergence of Bitcoin originated from scratch. It was preceded by numerous earlier studies, dating back to the 80s of the last century. In 1983, scientist David Chaum thought out a system for sending anonymous payments using the so-called “blind signature.”

Bitcoin’s Blockchain as Gold Standard Technology

The increased interest of many countries and large corporations in the financial sector to this technology is no longer the news for anyone. Blockchain is a decentralized center that allows transfers without the participation of any intermediaries.

In addition, the system has enhanced security, and transactions are protected by a special code that cannot be changed. Such factors only open up further prospects for the blockchain methodology as a means of payment.

What is the future of Bitcoin?

Nowadays, Bitcoin is not the only only one known currency in crypto space, there are many others. So why, Bitcoin? What about it versus other cryptocurrencies?

Bitcoin has many advantages compared to other cryptocurrencies, and we will take a close look at some of these points.

BTC is the oldest and most reliable cryptocurrency. It is the mother of all coins in the crypto exchange market, which means that most other cryptocurrencies are mainly traded to and from Bitcoin. It has the most real usage of any others and with the largest market capitalization and the least volatility. Bitcoin-based securities are most likely to get approved by regulators and thus become part of institutional investments and offerings. Bitcoin has the advantage of being better known, more widely used, and it has much better liquidity.

Various scaling upgrades have been implemented by Bitcoin users and companies that have added significant capacity. There are basically three main scaling upgrades that have an effect on the network right now:

  • Segregated Witness (SegWit) can theoretically provide over 100 % of extra capacity for the network. Currently, approximately 40 % of the network is making SegWit based transactions, which already provides a significant capacity boost.
  • Lightning network, which potentially could have a massive effect on capacity, is already being used for real bitcoin payments. At this moment, the effect of Lightning on the congestion and fees of the network is minimal, but it is expected to have a larger effect in the future. One real-life example of how Lightning is being used is Satoshi’s Place, where people paint pixels using Lightning. At its peak, there were over 1.000 transactions made per day in this service with very low fees and they did not cause almost any congestion on the Bitcoin blockchain. In summary, it has been proven that Bitcoin is highly reliable and that it can scale, which is a very positive fundamental value.
  • Transaction batching, which can provide an even larger boost than SegWit, has been implemented by more and more Bitcoin services recently. This means that instead of sending each payment in a separate transaction, exchanges and other services will wait until they have a larger amount of payments and batch them into a single transaction. This saves a huge amount of space, and more efficiency is expected in the future as there are still certain large exchanges that do not execute batching.
  • Finally, it is good to mention that Bitcoin is getting improvements in the privacy department. Future protocol upgrades such as Schnorr signatures will improve privacy, and payments made using the lightning network are generally considered significantly more private than regular Bitcoin transactions.
