Crypto Glossary

Any cryptocurrency other than Bitcoin. Popular examples include Ethereum (ETH), Solana (SOL), Cardano (ADA), and Litecoin (LTC).

The real rate of return earned on an investment, taking into account the compounding effect. Widely used across DeFi protocols to measure staking and liquidity rewards.

The world's first decentralized cryptocurrency, created in 2008 by Satoshi Nakamoto. Uses a peer-to-peer distributed ledger (blockchain) and Proof of Work consensus.

A decentralized, immutable data structure that records transactions into cryptographically linked blocks. Serves as a public distributed ledger maintained across nodes.

An online tool that allows users to search and inspect blocks, transactions, wallet addresses, and smart contracts on a blockchain in real time.

An offline storage mechanism for private keys (such as hardware wallets like Ledger or Trezor) designed to maximize security against cyber attacks.

The science of securing communications and data using mathematical algorithms. In blockchain, cryptography ensures data integrity and key control.

An application executed on a decentralized network of nodes via smart contracts rather than a centralized corporate server.

An organization governed by transparent smart contract rules on a blockchain, where token holders vote on key decisions and treasury management.

An ecosystem of open financial services (lending, trading, yield) built on blockchain networks without traditional banking intermediaries.

A potential flaw in digital cash schemes where the same digital token could be spent twice. Solved by Bitcoin via Proof of Work consensus.

The sandboxed execution environment that compiles and executes smart contract code on the Ethereum network and EVM-compatible chains.

The fee paid in a blockchain's native token to compensate validators or miners for the computational effort needed to process transactions.

The very first block mined on a blockchain network. Bitcoin's Genesis Block was mined by Satoshi Nakamoto on January 3, 2009.

A scheduled event in Bitcoin's protocol every 210,000 blocks (approx. 4 years) that cuts the block reward paid to miners in half.

A fixed-length string produced by a cryptographic hash function that uniquely identifies data inputs in an irreversible manner.

The base underlying blockchain architecture (such as Bitcoin, Ethereum, or Solana) responsible for settlement and network security.

A secondary framework built on top of a Layer 1 blockchain to process transactions off-chain, boosting throughput and reducing fees.

A mathematical tree structure used in blockchain to efficiently summarize and verify the integrity of large transaction datasets into a single root hash.

A computer connected to a blockchain network that stores a copy of the distributed ledger and validates transactions against consensus rules.

A consensus protocol where network validators stake native tokens as collateral for the right to validate transactions and propose new blocks.

The original consensus algorithm where network miners solve complex cryptographic puzzles using computing hardware to secure the network.

A self-executing software program stored on a blockchain that automatically enforces and executes predefined conditions without intermediaries.

The pseudonymous creator or group of creators who authored the Bitcoin white paper in 2008 and launched the network in 2009.

The process of locking tokens on a Proof of Stake network to help secure consensus in return for periodic percentage rewards.

An authoritative technical report published by protocol founders explaining the economic model, system design, and consensus mechanism.
