Blockchain is fast becoming one of the most relevant terms in the financial world, with the shift towards this type of technology accelerated by the COVID-19 pandemic.
Here, we give you a complete guide as to all things blockchain.
What is blockchain?
Blockchain is a digitally distributed, decentralised, public ledger that facilitates the process of recording transactions online.
The sole aim of blockchain is to store and share data, and the blocks contain all of the transactions that have taken place on the network.
In a blockchain, a request for a transaction is made and then the system authenticates this request. This leads to the creation of a 'block' representing the transaction, which is forwarded to every participant on the network.
The participants compete to validate the transaction, and when it is validated, the block is added to existing blocks, which in turn forms a chain.
This process whereby the various participants compete to authenticate a block and verify a transaction is known as "mining".
Who invented blockchain technology?
The foundation of blockchain technology can be accredited to David Chum, a Berkeley programmer who invented Blind Signature Technology in 1982.
Blind Signature Technology was an untraceable payment system which created a distinction between a person's identity and their transaction. (more information about Blockchain inventor)
How does a blockchain currency work?
Cryptocurrency is any form of currency that exists either in digital or virtual format and which uses cryptography to secure its transactions, and it can be used to make purchases online.
Cryptocurrencies run on blockchain, and the various units of cryptocurrency are created through a process of mining.
To make a transaction with cryptocurrency, you exchange currency with a peer through the use of a digital wallet known as a cryptocurrency wallet. This wallet is software that allows you to transfer funds from one account to another.
To complete a transaction, you need to have a password, which is known as a private key. You can own a number of keys and own all of the funds that are sent to each of these keys.
Transactions are recorded on a public ledger, and this ledger shows all of the transaction totals without revealing the identities of the parties involved.
What is the disadvantage of blockchain?
There are a number of advantages and disadvantages of blockchain, and one of the main disadvantages is problems with the network size.
For a blockchain to work at its optimal level, it must be a large, robust network with many users and a distributed grid of nodes. However, if this is not the case, it is difficult to reap the full benefit. (more information about blockchain disadvantages)
