Fungible token

Olga Hryniuk
Cryptocurrency
A token that is identical to many others and can be traded is fungible. For example, one ada is the same as all others and so is fungible. Shares in a company, gold bars, and US dollars, for example, are all fungible. Cryptos are usually fungible, but there are also unique, non-fungible tokens (NFTs).

Game theory

Olga Hryniuk
ResearchCardano
The study of logical decision-making made by players within the defined parameters of a system. Game theory provides mathematical frameworks for predicting interactions between people in a system, where they are all looking out for their best interests. Cardano uses game theory to help avoid economic attacks on the network.

Gas

Vcoincheck.io
GasVcoincheck.io
The fee required to execute a transaction or contract on the proof-of-work network. On Ethereum, for example, gas is paid in ether, the native cryptocurrency of Ethereum. Gas fee is determined by the network's demand and supply, and is paid to incentivize miners to process and validate transactions. Gas fees are essential to the network's efficiency and secu...

Genesis block

Vcoincheck.io
GenesisblockVcoincheck.io
The first block in a blockchain that sets the foundation for the network. It is usually created by the network's creator and contains unique data defining the initial state of the blockchain. Unlike other blocks, a genesis block doesn't reference any previous blocks and generates the initial supply of cryptocurrency or tokens. In Cardano, the genesis block w...

Governance

Olga Hryniuk
GovernanceDecentralization+ 3
There is no single decision-maker controlling Cardano's growth and development. Instead, decentralized processes empower ada holders to make suggestions and collaborate on decisions. All ada holders can suggest a change through the Cardano improvement proposal (CIP) system, or participate in Project Catalyst to vote on what changes should be made.

Hash rate

Vcoincheck.io
HashrateVcoincheck.io
Hash rate refers to the measurement of the processing power of a blockchain network, particularly in the context of proof of work (PoW) consensus algorithms. It measures the number of hash operations that a network can perform in a second. In a PoW, miners use specialized hardware to perform complex mathematical calculations, known as hash functions, to val...

Haskell

Olga Hryniuk
ProgrammingHaskell
A functional programming language with a focus on producing secure code.  Haskell is well suited to Cardano's high-assurance code, and the need for greater formal verification in the blockchain. Core parts of Cardano are written in Haskell and extensive testing processes ensure Plutus Core smart contracts work properly.

Hydra

Olga Hryniuk
HydraScalability
A family of protocols that overlay the layer 1 Cardano blockchain to process transactions off the main chain. Hydra uses the main ledger as the secure settlement layer, boosts throughput, minimizes the delay in starting to process transactions, incurs low to no costs, and greatly reduces storage requirements.

Hydra Head

Olga Hryniuk
HydraScalability
The first of several Hydra protocols, and the basis of improving Cardano's scalability. Each Hydra Head works as an off-chain mini ledger, similar but faster than the main on-chain ledger, shared between small groups of participants. Many complex protocols can be added as layers on top of Cardano.
