All You Need to Know About Blockchain

Blockchain may appear intimidating, but its basic idea is relatively straightforward. A blockchain is basically a digital database.

What is Blockchain?

Blockchain is the technology that allows cryptocurrencies to exist. It was first implemented in 2009 by Satoshi Nakomoto (the name used by the unknown inventor/s of bitcoin). This technology created the foundation of a new internet by allowing digital information to be distributed but not copied. Initially devised for the digital currency, Bitcoin (Buy Bitcoin), the tech community is now finding other potential uses for the technology.

The blockchain is a record of all transactions ever conducted on cryptocurrency networks that are kept publicly. It uses Cryptography to link and safeguard an ever-growing number of records

A block consists of a hash pointer, a timestamp, and transaction data. Blockchains, by their nature, are resistant to data change. It's an open, decentralized ledger that can quickly and accurately track transactions between two parties.

Decentralized

The blockchain is a decentralized technology that depends on a public network of computers that all follow the rules to validate transactions before adding them to the chain. It ensures security for both parties involved as well as the neutrality of the system.

Once the information has been recorded onto these blocks (the name given to each group of transaction records), it cannot be edited or deleted without affecting all subsequent blocks. This system makes fraud more complicated because this permanently recorded data acts as a deterrent to hackers, who need to rewrite the entire blockchain.

Blockchain works like a decentralized ledger that records every transaction and stores it on an online database. Think of the digital ledger as a history of banking transactions (or any information that you must securely store). Because crypto is decentralized, it’s vital that traders only use the best forex broker and its platform when trading.

Transparent

Anyone on the network can see the entire history of transactions (from the initial deposit to transfers and withdrawals), making it completely transparent and verifiable. Blockchain also solves problems related to traditional ledgers: all users have access to real-time information, and they can't store a centralized version of this information.

But what if everyone in this decentralized system could update their division of the ledger? What if one division edited their books first? There would now be two versions of the "truth", each with different transactions and balances. This instance is called a double-spend problem - and it's one of the biggest security challenges for digital transaction networks.

The blockchain solves this potential issue by allowing each party to store their private version of the ledger. All users have their own personal "keys" that identify them on the log. When they want to make a transaction, they need to use their key to digitally sign a message with two critical pieces of information: how much you're sending from your account and where you're sending it.

Secure

When combined, these keys provide a mathematical identity - meaning you can't pretend to be someone other than yourself. It means no one can cheat the system because everyone identifies themselves before making a transaction.

Additionally, it locks each transaction to the block that came before it. This system ensures no one can defraud other users by spending their money or making purchases in someone else's account. Each user is given a unique ID code before every transaction.

What's Next for Blockchain?

Conceived initially as a research project in 1991. Like most millennials its age, Blockchain has experienced its fair share of public criticism throughout the last two decades, with businesses all around the world wondering what the technology is capable of and where it's heading in the future.

Blockchain is finally gaining a name for itself at age twenty-seven, in no small part because of bitcoin and cryptocurrencies. Blockchain promises to improve business and government operations worldwide with fewer mediators by enabling them to be more accurate, efficient, secure, and inexpensive. If you master the art of trading crypto, you can build up a solid investment portfolio.

It's no longer a matter of "if" legacy businesses will embrace Blockchain in the third decade-it's a question of "when."
