Understanding Cryptocurrency and Blockchain

Understanding cryptocurrency and blockchain are fundamental to understanding the new economy. A person or entity known as Satoshi published an online paper outlining its principles back in 2008.
Cryptocurrency offers many advantages, such as being able to transfer money more cheaply without going through banks, using a database known as blockchain technology.
What is a blockchain?
Blockchains are databases that store information in blocks secured with cryptography, making it the perfect way to immutably record any type of data, from transactions and votes in elections, product inventories and state IDs, deeds to homes and more.
Blockchain differs from a traditional database in that its data are distributed among different computers in a network, known as nodes, that work together to keep it updated and secure.
Nodes within the network validate transactions using built-in protocols that ensure all in-network nodes converge on one set of data, eliminating the need for a central authority and saving on overhead while decreasing risks such as corruption or failure.
Blockchains can also be used to generate new cryptocurrencies, like Bitcoin. Mining involves using computer power to solve complex mathematical equations and verify transaction records that will later be added to the blockchain – creating units of cryptocurrency which can then be traded against goods or services.
What is a cryptocurrency?
Cryptocurrency is a digital medium of exchange that operates like money but doesn’t exist physically. It uses advanced software codes that protect and encrypt transactions while serving as an immutable public record of ownership known as blockchain technology.
Bitcoin, created in 2009 by an unknown person or group known only by their pseudonym Satoshi Nakamoto, is widely renowned as an emerging form of digital money exchange that allows individuals to send funds directly without intermediaries and at low costs.
Cryptocurrency values can be highly unpredictable, fluctuating significantly up or down in value over time. Your holdings could even be stolen if you misplace or missecure your private key (a string of numbers and letters) or your cryptocurrency wallet is breached – for this reason you should only invest money that can afford to be lost as unlike bank deposits your cryptocurrency holdings are uninsured, meaning they could easily be compromised if purchased from unregulated providers.
What are the benefits of a blockchain?
Blockchain has long been heralded as an innovative technology that could transform how businesses and governments operate, particularly due to its ability to foster trust through transparent data while decreasing intermediary dependence. One such capability that Blockchain offers is trust creation via transparent data while cutting down intermediary costs significantly.
Blockchains are databases that record transactions as digital blocks linked together in a digital chain. Each block in this chain includes hash pointers to its predecessor block and transaction information, timestamped by decentralized nodes that collectively agree on whether any new blocks should be validated.
As blockchain is distributed and immutable – meaning transactions recorded can’t be altered later – it provides trustworthiness and security to its participants, real-time records of transactions, real-time synchronized records of payments between participants that can be seen by all and transparency that helps eliminate errors and inefficiencies while being cost-effective and fast enough to reduce processing times and transaction fees.
What are the disadvantages of a blockchain?
Blockchain technology is well-renowned for its robust security. Unfortunately, its integration can sometimes be complex due to lack of standards across different blockchain platforms – something that may hinder development of seamless apps that could be applied across industries.
Blockchain’s primary drawback lies in its inability to easily reverse transactions once they’ve been recorded on its network, which may present difficulties in industries that require transaction reversals for error correction and fraud prevention purposes.
Blockchains are distributed networks that rely on considerable computational power and servers to run. Their high energy consumption raises environmental concerns. If a key holder dies or loses their private keys, their account cannot be accessed, similar to losing a safe combination at a physical bank. This can become particularly troublesome when people store sensitive information like criminal or medical records on them – potentially even precluding EU’s General Data Protection Regulation from becoming reality.
