How Crypto Blockchain Works: A Beginner's Guide
Cryptocurrencies are digital or virtual tokens that use cryptography to secure their transactions and to control the creation of new units. Cryptocurrencies are decentralized, meaning they are not subject to government or financial institution control. Bitcoin, the first and most well-known cryptocurrency, was created in 2009.
Cryptocurrencies are created through a process called mining. Miners are rewarded with cryptocurrencies for verifying and committing transactions to the blockchain. Blockchain is a public ledger of all cryptocurrency transactions.
How Bitcoin's Blockchain Works
The blockchain is a public ledger of all Bitcoin transactions. It is constantly growing as "completed" blocks are added to it with a new set of recordings. Each block contains a SHA-256 cryptographic hash of the previous block, a timestamp, and transaction data. Bitcoin nodes use the block chain to differentiate legitimate Bitcoin transactions from attempts to re-spend coins that have already been spent elsewhere.
How Ethereum's Blockchain Works
The Ethereum blockchain is a decentralized platform that runs smart contracts: applications that run exactly as programmed without any possibility of fraud or third party interference. Smart contracts are self-executing contracts that are automatically enforced and allow for transparency and trust between parties.

A (Very) Quick Guide to How Blockchain Works
If you’re curious about how blockchain works, but don’t have much time to spare, here’s a (very) quick guide.
1. Blockchain is a digital ledger of all cryptocurrency transactions. It is constantly growing as “completed” blocks are added to it with a new set of recordings. Each block contains a cryptographic hash of the previous block, a timestamp, and transaction data. Bitcoin, Ethereum, and other cryptocurrencies use blockchain to keep track of their transactions.
2. Cryptocurrencies are created as a reward for a process known as mining. Mining involves solving a difficult mathematical problem with a computer. When a miner solves the problem, they are awarded cryptocurrency.
3. Transactions on a blockchain are verified by network nodes through cryptography and recorded in a public distributed ledger. Nodes can agree to change the record of a transaction only if they receive the approval of majority of the network nodes.
4. Bitcoin was the first cryptocurrency to use blockchain technology, and Ethereum is its most popular platform. Other cryptocurrencies, such as Litecoin and Ripple, also use blockchain technology.
5. Bitcoin, Ethereum, and other cryptocurrencies are decentralized, meaning they are not subject to government or financial institution control. This makes them more difficult to criminalize and undermines centralized control of the financial system.
