What is Blockchain?
Blockchain is a distributed, decentralized, public ledger that records transactions across many computers so that any involved record cannot be altered retroactively, without the alteration of all subsequent blocks. This allows the participants to verify and audit transactions independently and relatively inexpensively.
Key Characteristics
- Decentralized: No single entity has control
- Transparent: All transactions are visible
- Immutable: Records cannot be altered
- Secure: Cryptographically protected
- Distributed: Data stored across network
How Blocks Work
Each block contains a cryptographic hash of the previous block, a timestamp, and transaction data. The linked blocks form a chain, with each additional block reinforcing those before it.
Consensus Mechanisms
Consensus mechanisms are protocols that ensure all nodes in a blockchain network agree on the validity of transactions, preventing double-spending and maintaining the integrity of the blockchain.
Proof of Work (PoW)
Miners compete to solve complex mathematical puzzles, with the winner getting to add the next block and receive rewards. Used by Bitcoin and originally by Ethereum.
Proof of Stake (PoS)
Validators are selected to create new blocks based on the amount of cryptocurrency they hold and are willing to "stake" as collateral. More energy-efficient than PoW.
Delegated Proof of Stake (DPoS)
Token holders vote for a small number of delegates who are responsible for validating transactions and maintaining the blockchain.
