Node (Full Node)
A copy of the software maintained by a participant within a blockchain network. A blockchain exists on nodes. If no nodes are online, a blockchain is offline and can’t be up to date or used. A full node maintains a full list of every single transaction that has occurred on a blockchain. It is a server that stores, updates and publicizes a full copy of the blockchain. Essentially, a full node is a program can fully validate transactions and blocks bolstering the p2p network while allowing other light nodes to connect with them. In the case of Proof-of-Work, miners are continuously required to run a full node in order to mine.
Node (Light Node)
A light node is only a partial list of every transaction that has occurred on a blockchain. A light node may only have blocks that were created very recently. Light nodes only contain partial blockchain histories but are usually connected with full nodes. This ensures that they remain synchronized, and that they can be used effectively.
Non-Fungible Token (NFT)
Non-fungible tokens (NFTs) are digital representations of data, that embed digital authenticity and ownership and support the creation of intangible assets. NFTs are essentially composable digital objects that fundamentally create unique opportunities and connections to off-chain analogues, and will support all metaverse assets and transform the class of intangible assets to a new class of assets.
Nonce is an abbreviation for the term “number only used once”. It is an essential part of each block processed in a Proof-of-Work blockchain. The nonce is a small piece of data in the block that is modified randomly and repeatedly. Miners keep hashing the data of the entire block that changes every time the nonce changes until they find a suitable outcome, the hash that solves the PoW puzzle and validates the block.
