Allowance
Token spending permission
Permission for a contract to spend a specified amount of a token. It is different from transferring that token immediately.
Explore Ethereum →Atomic settlement
All-or-nothing exchange
An exchange whose required steps succeed together or do not take effect. Its guarantees apply only within the mechanism’s defined scope.
Explore Solana →Block
A batch of accepted transactions
A data structure added to a blockchain under its consensus rules. Inclusion and finality are different milestones.
Explore Bitcoin →Bridge
Cross-network messaging or asset transfer
A system linking separate networks. It adds assumptions about message verification, operators and custody.
Explore Ethereum →Canonicalisation
A consistent data representation
Rules that convert equivalent structured data into a standard representation before hashing or signing it.
Explore AI & Web3 →Circulating supply
Tokens considered available in the market
A provider-defined supply measure. Locked, treasury and circulating classifications need an explicit method and timestamp.
Explore Markets →Collateral
Assets backing an obligation
Assets posted against a loan or other obligation. Their valuation and liquidation rules determine how much protection they provide.
Explore DeFi →Confirmation
Evidence of transaction inclusion
A milestone showing acceptance by a network. More confirmations or a stronger commitment level can reduce reversal uncertainty.
Explore Bitcoin →Custody
Control of asset access
The arrangement determining who controls the keys or account permissions needed to move assets.
Explore Bitcoin →DEX
Decentralised exchange
A venue using blockchain-based trading mechanisms. Interfaces, routing and infrastructure may still depend on separate operators.
Explore DeFi →Digest
A fixed-size cryptographic fingerprint
The result of hashing data. A matching digest checks consistency with a reference, not whether the source data is truthful.
Explore AI & Web3 →FDV
Fully diluted valuation
A price multiplied by a chosen diluted supply figure. It is not the money invested in a token or cash available to sellers.
Explore Markets →Finality
A network commitment milestone
The point at which consensus rules provide a stronger assurance that a transaction will remain accepted. Definitions vary by network.
Explore Ethereum →Gas
Execution resource accounting
A measure used to price computational work on Ethereum. Gas units and the price paid per unit are separate inputs.
Explore Ethereum →Health factor
A lending-position risk measure
A protocol-specific ratio describing the margin between collateral support and debt. Crossing a threshold may allow liquidation.
Explore DeFi →Liquidity
Capacity to execute an exchange
The depth available for trading at and around a price. Trading volume and market capitalisation do not measure the same thing.
Explore Markets →MEV
Value from transaction ordering
Value that can arise from the ordering, inclusion or exclusion of transactions. It is not limited to one type of trading strategy.
Explore Ethereum →Mint address
A Solana token identifier
The public address of the mint account defining a particular token. Tickers and logos are not unique identifiers.
Explore Solana →Oracle
A source of external data for a contract
An arrangement that supplies information such as prices. Freshness, aggregation and failure behaviour matter alongside accuracy.
Explore DeFi →PDA
Program-derived address
A Solana address derived from inputs and a program ID, without a corresponding private key. Program rules govern its use.
Explore Solana →Price impact
How an order changes its execution price
The difference caused by an order consuming available liquidity. It is distinct from market movement while a transaction waits.
Explore Markets →Private key
A secret used to authorise signatures
Secret cryptographic material controlling a signing identity. A legitimate news publication does not need it.
Explore Bitcoin →Receipt
A portable record of a result
Structured evidence of inputs, checks or outcomes. Its evidentiary value depends on provenance and verification, not just its format.
Explore AI & Web3 →RPC
An interface to network data and actions
A service through which software reads blockchain state or submits requests. A working interface does not guarantee fresh data.
Explore Solana →Slippage
A change from the expected execution outcome
A difference between an expected price and eventual execution. A slippage limit constrains acceptance but cannot guarantee a fill.
Explore Markets →Stablecoin
A token targeting a reference value
A cryptoasset designed to track a currency or other reference. Reserve, redemption and market risks can break that relationship.
Explore DeFi →Staking
Participation using committed assets
A mechanism that commits assets under protocol rules. Responsibilities, rewards, penalties and withdrawal conditions differ.
Explore Ethereum →UTXO
An unspent transaction output
A discrete Bitcoin output that can be spent as an input to a later transaction. Wallet balances aggregate eligible outputs.
Explore Bitcoin →Zero-knowledge proof
A proof with limited disclosure
A technique for proving a statement while withholding specified underlying information. It does not automatically hide all network or application data.
