"Ethereum is a technology for building apps and organizations, holding assets, transacting and communicating without being controlled by a central authority. There is no need to hand over all your personal details to use Ethereum - you keep control of your own data and what is being shared. Ethereum has its own cryptocurrency, Ether, which is used to pay for certain activities on the Ethereum network."

Arbitrum is a Layer 2 solution for Ethereum that scales its capabilities while maintaining its security. It uses a mechanism called "rollup" to bundle multiple transactions into a single one, reducing fees and increasing transaction throughput. By optimizing computation off-chain and only submitting necessary data on-chain, Arbitrum improves Ethereum's performance and provides a smoother user experience.


ERC20 is a standard for tokens on the Ethereum blockchain. It provides a predefined set of rules that any token following the ERC20 standard must implement. ERC20 tokens are typically used for value transfer within Ethereum-based applications, ICOs (Initial Coin Offerings), and as the building blocks for other token standards.


ERC721 is a standard for non-fungible tokens (NFTs) on the Ethereum blockchain. Unlike ERC20 tokens, which are identical to each other, ERC721 tokens are unique. Each token represents ownership over a distinct asset or piece of content, often used for digital art, collectibles, and in-game items.


As of my knowledge cutoff in September 2021, there is no ERC721A standard. If there has been such a standard created after that date, I suggest looking into Ethereum's official documentation or reaching out to Ethereum community channels for an accurate description.

Turn-Based Games

Turn-based games are a type of game where players take turns to make moves. This contrasts with real-time games, where all players can act simultaneously and continuously. In the context of blockchain, turn-based games can be implemented with smart contracts, recording each move as a transaction on the blockchain.


MMO stands for Massively Multiplayer Online game. These are games where a large number of players can play together in the same virtual world. The virtual world persists over time and player actions can have lasting impacts. Some MMOs have integrated blockchain technology to enable players to truly own their in-game assets.


Proc-Gen, short for procedural generation, is a method of creating data algorithmically as opposed to manually. In gaming, this often refers to the creation of game environments, levels, assets, or other content. This can make games more varied and replayable. In blockchain games, proc-gen can be used to create unique assets like NFTs.
