What is Cryptoccurrencies

 Bitcoin, known as "digital gold" is the first and most recognized cryptocurrency in the world. Launched in 2009, Bitcoin is the first decentralized digital currency that does not rely on any banks, governments or intermediaries to facilitate payment.


Over the years, Bitcoin has developed from a niche experiment to a globally accepted form of financial asset, with many investors, businesses, and everyday individuals using it. In this article we will discuss what Bitcoin is, how it works and its advantages, disadvantages, and future.


What is Bitcoin?


Bitcoin (BTC) is a peer-to-peer digital currency that allows users to transfer and receive money over the internet without having to go through any third-party entity. Bitcoin is not printed by governments or a banking system, but instead operates through a decentralized network of computers, all adhering to the same set of protocols to offer trust, security and transparency for the transaction.


Key Features of Bitcoin:


A Decentralized System


A fixed supply of 21 million coins


Truly secure and transparent


No borders or restrictions


How does Bitcoin Work?

The Blockchain Technology


Bitcoin makes use of the blockchain technology, which is a public and distributed ledger for storing, recording and tracking every transaction for all Bitcoins. Each transaction is recorded in a block, and blocks are linked together to create a chain of transactions (the blockchain).

Ethereum (ETH) - a brief history


As the world's second-largest cryptocurrency, behind only bitcoin, Ethereum is one of the most significant blockchain platforms ever created. The ability for developers to build decentralized applications (dApps) on top of Ethereum is transformative for the entire cryptoeconomy.


Ethereum is a publicly accessible, decentralized blockchain platform that allows developers to create and deploy smart contracts and dApps on its ecosystem.


Ether (ETH) serves as Ether's native cryptocurrency, enabling users to:


1. Pay for transaction (gas) fees

2. Safeguard the network

3. Serve as a means of powering Smart Contracts and dApps


Ethereum's Working Mechanism - Blockchain and Smart Contracts


Ethereum operates on a blockchain similar to Bitcoin, but it adds additional capabilities to that blockchain. Ethereum's key innovation is smart contracts, which are self-executing programs that run automatically when a set of conditions is met.


The removal of intermediaries from the transaction process has provided:


faster and more affordable transactions

trustless transactions


Ethereum Virtual Machine (EVM) - The EVM is the computation engine that drives Ethereum-based applications.

Solana is a very fast and affordable blockchain designed to host a variety of different types of decentralized apps (DApps) and decentralized finance (DeFi) solutions. Solana was first introduced by Anatoly Yakovenko in 2020 and has rapidly gained traction as one of the most popular and effective blockchains in the industry due to its ability to process thousands of transactions every second with very low fees, Solana is often referred to as an "Ethereum Killer," even though Solana has a slightly different function compared to Ethereum.


What is Solana?


Solana is a decentralised blockchain that supports smart contracts and DApps. SOL is the native cryptocurrency of Solana and can be used for the following:


Transaction fees


Securing and staking the network


Governance and participation in the ecosystem


The primary objective of Solana is to address the issues associated with slow transaction speeds and high transaction fees that are commonly associated with existing blockchains.


How Does Solana Work?

Proof of History (PoH) Explained


Solana introduced an innovative concept called Proof of History (PoH), which is a mathematical concept (cryptographic) that enables the network to create a time stamp for each transaction prior to adding it to the blockchain.


This enables the network to:


Efficiently order transactions


Increase transaction processing speed


Decrease transaction congestion


In order to secure the network, Solana uses both Proof of History (PoH) and Proof of Stake (PoS).
