This decentralized nature distinguishes blockchain from traditional systems, ensuring transparency and security in an unprecedented way.
II. How Does Blockchain Work?
To comprehend the inner workings of blockchain, let's break down the steps involved in a typical transaction. Imagine Alice wants to send Bob some cryptocurrency:
- Alice initiates the transaction by creating a digital signature using her private key.
- The transaction is then broadcasted to the network, where nodes validate its authenticity.
- Miners, the backbone of blockchain, compete to solve complex mathematical puzzles to validate and add the transaction to a block.
- Once a miner successfully solves the puzzle, the block is added to the blockchain, linking it to previous blocks.
- The transaction is now confirmed and recorded in a public ledger, accessible to all participants in the network.
Consensus algorithms, such as proof-of-work (PoW) or proof-of-stake (PoS), ensure the integrity of the blockchain. Miners in PoW systems dedicate computational power to solve puzzles, while PoS systems rely on participants' ownership of cryptocurrency to validate transactions. These algorithms prevent malicious actors from manipulating the blockchain.
