How Does Cryptocurrency Work?

Cryptocurrency relies on blockchain technology to function. At its core, a blockchain is a decentralized digital ledger that records all transactions across a network. Each transaction is grouped into a block, which is then added to the chain. This structure ensures transparency and security.

Mining and Consensus Mechanisms

New blocks are added to the blockchain through consensus mechanisms like Proof-of-Work (PoW) or Proof-of-Stake (PoS).

• PoW requires participants to solve complex mathematical puzzles, securing the network but consuming significant energy.
• PoS, on the other hand, allows users to validate transactions based on the number of coins they hold, making it more energy-efficient.
