Cryptocurrency is an independent digital currency that utilizes cryptography and decentralized tech to enable secure and anonymous transactions between individuals. It’s appeal is it’s free from central bank or government control. This technology is based on a distributed ledger known as the “blockchain”. This blockchain is maintained by a network of computers rather than a single authority. Every transaction made on the network is recorded in a block on the chain, which is validated and added to the chain through a process called “mining”.
Yes, think of gold mining just without the picks and the hard hats. This is virtual.
Mining involves solving complex math equations using souped-up computers to verify transactions and add them to the blockchain. In turn for doing that, these miners are given a small amount of cryptocurrency for every block they add to the chain. (Nice work!) Once a transaction is added to the blockchain, it is immutable and cannot be modified, making it a secure and transparent way to record transactions. However, the anonymity of cryptocurrency transactions has led to its use in illegal activities such as money laundering and drug trafficking.
Cryptos are stored in digital wallets, which can be software or hardware-based, and provide a secure and convenient way to store, send, and receive cryptocurrency. These wallets typically feature a public key and a private key, which are used to encrypt and decrypt transactions. The public key is used to receive funds, while the private key is used to authorize transactions.
One of the main advantages of cryptocurrency is its decentralized nature. This enables transactions to be made without the need for intermediaries such as banks, which can be slow and costly. The decentralization of cryptocurrency also presents a number of challenges: there is no way to reverse a transaction or recover lost funds, hacking and cyberattacks.
To address these challenges many in crypto are been working on creating more secure and stable digital currencies. Think Ripple and Stellar. These are designed to be used in financial transactions and can facilitate the exchange of different currencies. Others, including Ethereum, are designed to enable the creation of decentralized applications that can run on the blockchain.
