<h2>Deterministic</h2>
Deterministic (from determinism, which means lack of free will) is the opposite of a random event. It tells us that some future event can be calculated exactly, without the involvement of randomness. For example, the conversion between Celsius and Kelvin is deterministic, because the formula is not random, it is an exact formula that will always give you the correct answer (assuming you perform the calculations correctly):

Every NFT can be differentiated from another through a 1-of-1 tokenID and its unique contract address. From there, metadata such as images, video files, or other data can be attached, meaning that it’s possible to own a token that represents a unique digital object.<ref name="dNFT" /> In its most bare-bones form, an NFT is simply a transferable token that has a unique tokenID.

Glossary

The Crypto and Chainlink ecosystem can at times seem a complex worlds with a quickly evolving vocabulary. The glossary aims to increase technical knowledge and to help the user better understand key concepts found across the Wiki.

Aggregation


API


Blockchain's

A blockchain is a highly secure and decentralized network that allows people to store data, exchange value, and record transaction activity in a shared ledger that is not controlled by any central authority.[1]

Bridging assets

REVISE To transfer assets from Ethereum to BNB Chain you will need to interact with the Binance Bridge. This is a contract that will take custody of your assets on the Ethereum side and, after a bit of a delay, create a version of that asset on the Binance side.

You might think about this as a little like using tokens in an arcade. You give the arcade employee (bridge contract) your money (ETH) and in turn, they create tokens (ETH BEP-20, A BEP-20 version of ETH) to use within the arcade (BNB Chain). From there you can use the tokens (ETH BEP-20) while you are in the arcade. If you would like to leave you can give your tokens (ETH BEP-20) back to the employee (bridge contract) and they will destroy or burn the tokens (ETH BEP-20). Then they’ll give you back the money (ETH) for the tokens (ETH BEP-20). [2]

Deterministic

Deterministic (from determinism, which means lack of free will) is the opposite of a random event. It tells us that some future event can be calculated exactly, without the involvement of randomness. For example, the conversion between Celsius and Kelvin is deterministic, because the formula is not random, it is an exact formula that will always give you the correct answer (assuming you perform the calculations correctly):

If something is deterministic, you have all of the data necessary to predict (determine) the outcome with 100% certainty.[3]
Put more succinctly "Always producing the same outcome from the same starting point."

Deviation threshold

A new data aggregation round starts when a Chainlink node identifies that an off-chain data value deviates by more than the defined deviation threshold from its on-chain value.

DLT

DONs

Each DON is customizable, empowering users to pick specific node operators and data sources, the level of decentralization, the type of computation performed, the update frequency, the blockchain it’s deployed on, and various other optimizations that align with the user’s own budget, performance requirements, privacy needs, and trust assumptions.

Dynamic NFTs (dNFTs)

A dynamic NFT is an NFT that can change based on external conditions. Change in a dynamic NFT often refers to changes in the NFT’s metadata triggered by a smart contract. [4] DNFTs can also be described as perpetual smart contracts that use oracles to communicate with and react to external data and systems.

Heartbeat threshold

A new data aggregation round starts after a specified amount of time from the last update. If the deviation threshold is not reached within the time of the heartbeat, the feed will be updated.

Heterogeneous network

https://blog.chain.link/how-chainlink-supports-any-off-chain-data-resource-and-computation/

Hybrid smart contracts

Hybrid Smart Contracts describe smart contracts which perform computations both on-chain and off-chain, resulting in the creation of decentralized applications that are more advanced than on-chain logic in isolation.[5] https://blog.chain.link/hybrid-smart-contracts-explained/

Layer 0

‘A communication protocol, enabling smart contract execution across multiple chains, with one transaction from any one source chain, enabling cross-chain functionality for dApps and (native) token bridging’. Looking for citation.
