Crypto Basics
Blockchain is a decentralized technology that records transactions across a network of computers instead of storing data in a single central database. It is the core technology behind many cryptocurrencies, such as Bitcoin and Ethereum.
Here is a simple explanation of how blockchain works:
1. Transaction Initiation
A user initiates a transaction, such as sending cryptocurrency to another user.
2. Transaction Verification
The transaction is broadcast to a decentralized network of computers called nodes. These nodes verify the transaction using consensus mechanisms.
3. Block Creation
Once verified, the transaction is grouped with other transactions into a block.
4. Block Added to the Chain
The new block is linked to previous blocks, forming a secure chain of data known as the blockchain.
5. Permanent Record
After the block is added, the transaction becomes part of the permanent ledger and cannot easily be altered.
Because blockchain networks are decentralized and transparent, they help improve security and reduce the risk of fraud in the Crypto ecosystem.
This technology is widely used not only for cryptocurrencies but also for applications such as smart contracts, decentralized finance (DeFi), and digital identity systems.
