Genesis Block: The first block in a blockchain. It serves as the foundation for all the subsequent blocks added to the chain.
Governance Token: A token that grants holders the right to vote and contribute to ecosystem decision-making.
GPU (Graphics Processing Unit): A component used in mining cryptocurrency to ensure faster computation compared to speed achieved using traditional CPUs
H
Hash Rate: The measure of computational power per second used in crypto mining
Hard Fork: A significant change made to a blockchain protocol that results in a permanent divergence from the previous version of the blockchain.
HODL: A misspelling of "hold" that is now acceptable in the crypto space and used to describe keeping a token for the long term instead of selling.
Hot Wallet: A cryptocurrency wallet that is connected to the internet to facilitate easy access to fund
Halving: A systemic design used by Bitcoin to reduce the rewards for mining new blocks.

Keeper: Used to describe market participants who enhance the stability of an ecosystem by holding the ecosystem token.
L
Layer 1: The base layer of blockchain, which includes its primary protocol and network. Popular blockchains like Bitcoin and Ethereum are Layer 1 blockchains that provide a base to build Layer 2.
Layer 2: The secondary framework built on the Layer 1 blockchain is designed to improve system efficiency and scalability.
Liquidity: The ease with which a crypto asset can be bought or sold in the market without necessarily affecting its price. It implies the availability of enough tokens for transactions.
