Hacking – The act of gaining unauthorized access to computer systems, networks, or data, often to exploit vulnerabilities for malicious or ethical purposes.

Hal Finney – A prominent computer scientist and cryptographer who contributed to the development of Bitcoin and was the recipient of the first Bitcoin transaction from its creator, Satoshi Nakamoto.

Hard Cap – The maximum amount of funds a blockchain project aims to raise during its token sale or crowdfunding campaign, representing an absolute fundraising limit.

Hard Fork (Blockchain) – A radical upgrade or change to a blockchain network’s protocol, resulting in a permanent divergence into two separate chains, one following the new rules and the other the old ones.

Hard Fork Combinator – A mechanism or framework in blockchain development that allows combining successive protocol upgrades seamlessly without disrupting the network.

Hard Peg – A fixed exchange rate policy where a currency’s value is tightly bound to another currency or a standard like gold, with minimal fluctuation.

Hardware Security Module – A physical device used to securely generate, store, and manage cryptographic keys, ensuring high levels of data and transaction security.

Hardware Wallet – A physical device designed to store cryptocurrency private keys securely offline, protecting them from hacking and unauthorized access.

Hash – A fixed-length alphanumeric string generated by a mathematical algorithm that represents data input, ensuring data integrity and uniqueness.

Hash Power / Hash Rate – The computational power used in mining or validating transactions on a blockchain, measured in hashes per second.

Hashgraph Consensus Mechanism – A distributed ledger technology that achieves consensus through a gossip protocol and virtual voting, enabling fast and secure transaction processing.

Haskell Programming Language – A statically typed, functional programming language known for its strong mathematical foundation, purity, and support for advanced abstractions.

Hedge Fund – An investment fund that pools capital from accredited investors and employs various strategies to generate returns, often including leverage and derivatives.

Hierarchical Deterministic Wallet (HD Wallet) – A type of cryptocurrency wallet that generates a tree-like structure of private and public keys from a single seed, simplifying key management.

Higher High – In technical analysis, a price point that is higher than the previous high, often indicating an uptrend in the market.

Higher Low – A price point in a financial market that is higher than the previous low, often signaling a potential upward trend.

HODL – A slang term in the cryptocurrency community meaning “Hold On for Dear Life,” encouraging investors to keep their assets despite market fluctuations.

Hostage Byte Attack – A cybersecurity threat where attackers corrupt or withhold blockchain data by exploiting byte storage in smart contracts.

Hosted Wallet – A cryptocurrency wallet managed by a third-party service provider, where the provider holds the private keys on behalf of the user.

Hot Storage – A method of storing cryptocurrency or data in an online environment, making it easily accessible but more vulnerable to cyberattacks.

Hot Wallet – An internet-connected cryptocurrency wallet used for quick access and transactions, though it carries higher security risks compared to offline storage.

Human Keys – A term referring to cryptographic keys that are designed or managed with human involvement, emphasizing user-centric security practices.

Human-Readable Names – Easily understood text-based identifiers used in place of complex alphanumeric strings, often for simplifying interactions, such as in blockchain addresses or domain names.

Huobi BTC (HBTC) – A Bitcoin-pegged token issued on the Ethereum blockchain, backed 1:1 by Bitcoin and managed by the Huobi cryptocurrency exchange.

Hybrid PoW/PoS – A blockchain consensus mechanism combining Proof of Work (PoW) and Proof of Stake (PoS), designed to leverage the benefits of both systems while addressing their limitations.

Hydra (Cardano) – A scalability solution for the Cardano blockchain that uses off-chain protocols to enable fast and low-cost transactions while maintaining security.

Hyperinflation – An economic condition characterized by an extremely rapid and uncontrollable increase in prices, eroding the value of a currency.

Hyperledger (Hyperledger Foundation) – An open-source collaborative project hosted by the Linux Foundation, focusing on developing blockchain technologies for business applications.
