Blockchain is the infrastructure layer behind crypto and Web3. But its terminology can feel technical and abstract at first.
This guide breaks down core blockchain terms in plain, direct language.
Blockchain
A decentralised digital ledger that records transactions across many computers.
Distributed Ledger
A database shared across a network rather than stored in one central location.
Node
A computer that participates in validating and storing blockchain data.
Validator
A node responsible for confirming transactions and maintaining network security.
Consensus Mechanism
The process used by a blockchain to agree on valid transactions. Examples include Proof of Stake and Proof of Work.
Proof of Stake
A consensus system where validators stake tokens to secure the network.
Proof of Work
A consensus system where miners solve computational puzzles to secure the network.
Layer 1
A base blockchain network, such as Ethereum or Solana.
Layer 2
Scaling solutions built on top of Layer 1 blockchains.
Transaction
A recorded action on a blockchain, such as sending tokens or executing a smart contract.
Immutable
Data that cannot be altered once recorded on the blockchain.
Fork
A change or upgrade to blockchain protocol rules.
Blockchain is the foundation of decentralised technology. Understanding the basics unlocks everything built on top of it.
