ABSTRACT

Bitcoin is the simplest way to exchange money.

Bitcoin is a software-based online payment system described by Satoshi Nakamoto in 2008 and introduced as open-source software in 2009. Payments are recorded in a public ledger using its own unit of account, which is also calledbitcoin.Payments work peer-to-peer without a central repository or single administrator, which has led the US Treasury to call bitcoin a decentralized currency. Although its status as a currency is disputed, media reports often refer to bitcoin as a cryptocurrency or digital currency.

INTRODUCTION

Bitcoin uses peer-to-peer technology to operate with no central authority or banks; managing transactions and the issuing of bitcoins is carried out collectively by the network.Bitcoin is open-source; its design is public, nobody owns or controls Bitcoin and everyone can take part. Through many of its unique properties, Bitcoin allows exciting uses that could not be covered by any previous payment system.

How does Bitcoin work?

As a new user, you can get started with Bitcoin without understanding the technical details. Once you have installed a Bitcoin wallet on your computer or mobile phone, it will generate your first Bitcoin address and you can create more whenever you need one. You can disclose your addresses to your friends so that they can pay you or vice versa. In fact, this is pretty similar to how email works, except that Bitcoin addresses should only be used once

Balances- block chain

The block chain is ashared public ledgeron which the entire Bitcoin network relies. All confirmed transactions are included in the block chain. This way, Bitcoin wallets can calculate their spendable balance and new transactions can be verified to be spending bitcoins that are actually owned by the spender. The integrity and the chronological order of the block chain are enforced with cryptography

Transactions- private keys

A transaction isa transfer of value between Bitcoin walletsthat gets included in the block chain. Bitcoin wallets keep a secret piece of data called a private key or seed, which is used to sign transactions, providing a mathematical proof that they have come from the owner of the wallet. The signature also prevents the transaction from being altered by anybody once it has been issued. All transactions are broadcast between users and usually begin to be confirmed by the network in the following 10 minutes, through a process called mining.

Processing- mining

Mining is adistributed consensus systemthat is used to confirm waiting transactions by including them in the block chain. It enforces a chronological order in the block chain, protects the neutrality of the network, and allows different computers to agree on the state of the system. To be confirmed, transactions must be packed in a block that fits very strict cryptographic rules that will be verified by the network. These rules prevent previous blocks from being modified because doing so would invalidate all following blocks. Mining also creates the equivalent of a competitive lottery that prevents any individual from easily adding new blocks consecutively in the block chain. This way, no individuals can control what is included in the block chain or replace parts of the block chain to roll back their own spends.

Bitcoin for Individuals

Mobile payments

Bitcoin on mobiles allows you to pay with a simple two step scan-and-pay. No need to sign up, swipe your card, type a PIN, or sign anything. All you need to receive Bitcoin payments is to display the QR code in your Bitcoin wallet app and let your friend scan your mobile, or touch the two phones together (using NFC radio technology).

Security and control over money

Bitcoin transactions are secured by military grade cryptography. Nobody can charge you money or make a payment on your behalf. So long as you take the required steps toprotect your wallet, Bitcoin can give you control over your money and a strong level of protection against many types of fraud.

Works everywhere, anytime

Just like with email, you don’t need to ask your family to use the same software or the same service providers. Just let them stick to their own favourites. No problem there; they are all compatible as they use the same open technology.

Fast international payments

Bitcoins can be transferred from Africa to Canada in 10 minutes. There is no bank to slow down the process, level outrageous fees, or freeze the transfer. You can pay your neighbours the same way as you can pay a member of your family in another country.

Zero or low fees

Bitcoin allows you to send and receive payments at very low cost. Except for special cases like very small payments, there is no enforced fee. It is however recommended to pay a higher voluntary fee for faster confirmation of your transaction and to remunerate the people who operate the Bitcoin network.

Protect your identity

With Bitcoin, there is no credit card number that some malicious actor can collect in order to impersonate you. In fact, it is even possible to send a payment without revealing your identity, almost just like with physical money. You should however take note that some effort can be required to protect your privacy.

The lowest fees out there

Bitcoin’s high cryptographic security allows it to process transactions in a very efficient and inexpensive way. You can make and receive payments using the Bitcoin network with almost no fees. In most cases, fees are not strictly required but they are recommended for faster confirmation of your transaction.

Protection against fraud

Any business that accepts credit cards or PayPal knows the problem of payments that are later reversed. Chargeback frauds result in limited market reach and increased prices, which in turn penalizes customers. Bitcoin payments are irreversible and secure, meaning that the cost of fraud is no longer pushed onto the shoulders of the merchants.

Fast international payments

Bitcoins can be transferred from Africa to Canada in 10 minutes. In fact, bitcoins never have any real physical location, so it is possible to transfer as many of them anywhere with no limits, delays, or excessive fees. There are no intermediate banks to make you wait three business days.

No PCI compliance required

Accepting credit cards online typically requires extensive security checks in order to comply with the PCI standard. Bitcoin still requires you to secure your wallet and your payment requests. However, you do not carry the costs and responsibilities that come with processing sensitive information from your customers like credit card numbers.

Get some free visibility

Bitcoin is an emerging market of new customers who are searching for ways to spend their bitcoins. Accepting them is a good way to get new customers and give your business some new visibility. Accepting a new payment method has often shown to be a clever practice for online businesses.

Conclusion

We can Sendbitcoinfrom your computer, tablet, smart phone or other device, to anyone, anywhere in the world, day or night. Bitcoinis an innovative payment network and a new kind of money. Every informed person needs to know about Bitcoin because it might be one of the world’s most important developments.
