Nakamoto Consensus
A decentralized system used by blockchains like Bitcoin to agree on the valid state of the ledger through Proof of Work, without relying on a central authority.
Name Wrapper
A smart contract that converts registered Ethereum Name Service (ENS) names into NFTs, enabling greater flexibility, transferability, and programmable use across dApps.
Negative Volume Index (NVI)
A technical indicator that evaluates how price movements behave on days with lower trading volume. It assumes that informed investors act on quieter days, making NVI a helpful tool for spotting underlying trends.
Net Asset Value (NAV)
The total value of an entity’s assets minus its liabilities, often used to measure the per-share value of a fund or investment product.
Network
The collective group of nodes operating a blockchain, each storing and validating the distributed ledger at any moment in time.
Network Latency
The delay it takes for information to move between nodes or computers across a blockchain or internet network, usually measured in milliseconds.
Network States
A new sociopolitical idea where communities form digital-first societies with shared rules, economies, governance, and culture — made sovereign by technology rather than geography.
Network-Enhanced Virtual Machine (NEVM)
A smart contract framework that blends Bitcoin’s security model with Ethereum’s programmability, designed for cross-chain operability and mass adoption scalability.
Newb
Slang for someone who is new or inexperienced in crypto trading or blockchain technology.
NFT Floor Prices
The lowest listed price for an NFT in a specific collection, often used as a quick indicator of that collection’s current market value.
NFT Mystery Boxes
Digital collectible packages that contain random NFTs, where the exact contents are unknown until the buyer opens the box.
NFT Royalties
Built-in smart contract fees that automatically reward NFT creators with a percentage of future resale transactions on supported marketplaces.
NGMI
Short for “Not Gonna Make It.” A dismissive crypto slang term used to express skepticism or doubt about someone’s investment decision, outlook, or conviction.
Nick Szabo
A computer scientist and cryptographer best known for pioneering the concepts of smart contracts and creating Bit Gold — a precursor to Bitcoin.
Nifty Gateway

No-Coiner
A person who does not own any cryptocurrency and generally expresses disbelief or cynicism about the viability or future of crypto assets.
Node
A fundamental component of blockchain infrastructure responsible for storing a full or partial copy of the ledger and contributing to network operations such as validation and broadcasting.
Node.js
A JavaScript runtime built on Chrome's V8 engine, commonly used to run server-side code and build backend services — including blockchain tools and APIs.
Nominators
Participants in a Nominated Proof-of-Stake (NPoS) system who delegate their tokens to validators, playing a critical role in securing the network and influencing who gets to produce blocks.
Non-Custodial
Describes wallets or services where users retain full control of their private keys and assets, without needing to trust a third-party custodian.
Non-fungible Assets
Assets that are unique and non-interchangeable, often issued within a collection (like NFTs), where each token carries distinct metadata or value.
Non-Fungible Token (NFT)
A blockchain-based token that represents a unique asset, such as digital art or game items, and cannot be exchanged on a one-to-one basis like fungible cryptocurrencies.
Nonce
An arbitrary number used once in cryptographic processes like mining. It’s adjusted repeatedly by miners when solving the proof-of-work algorithm for a block.
Nonce Error
Occurs when a previously used nonce value is reused or incorrectly applied, often causing transaction failures or inconsistencies in blockchain systems.
Notarization on Blockchain
The process of time-stamping a document or data on-chain, proving its existence at a specific time and providing an immutable record of authorship or claim.
