The term "Chain Game" in the on-chain context refers to games developed and run on a blockchain. On-chain games take advantage of the advantages of blockchain technologies, such as transparency, immutability and decentralization, to offer a unique and reliable gaming experience.
What is Blockchain?
Blockchain is a distributed ledger technology that allows a growing list of records, called blocks, to be maintained in a secure and verifiable manner. Each block contains a list of transactions and is linked to the previous block, forming a continuous chain. Key features of the blockchain include:
Decentralization: There is no central authority that controls the chain.
Immutability: Once data is recorded on the blockchain, it cannot be altered without consensus.
Transparency: All transactions are visible to all participants in the network.
Benefits of On-Chain Gaming
Digital Asset Ownership: Players can own and trade digital assets, such as NFTs (non-fungible tokens), that represent in-game items.
Transparency: All transactions and game rules are publicly available on the blockchain, ensuring fairness.
Interoperability: Assets and characters from one game can be used in other compatible games and applications.
Security: The decentralized and cryptographically secure nature of the blockchain protects against fraud and manipulation.
Examples of Chain Games On-Chain
Cryptokitties:
Description: An Ethereum-based game that allows players to breed, collect, and trade unique digital cats.
Technology: Use smart contracts to manage cat reproduction and transactions.
Axie Infinity:
Description: An Ethereum-based strategy game where players collect, raise and fight creatures called Axies.
Technology: Axies and other in-game items are NFTs that players can buy, sell, and use in-game.
Decentralized:
Description: A virtual world where players can buy land, build and monetize their creations.
Technology: Uses the Ethereum blockchain for land ownership and digital content creation.
How On-Chain Chain Games Work
Smart Contracts:
Smart contracts are programs that run on the blockchain and automate the rules of the game.
Example: In Cryptokitties, smart contracts manage the reproduction of cats and transactions between players.
Tokens No Fungibles (NFTs):
NFTs are unique tokens that represent in-game digital assets, such as characters, items, or terrain.
Example: In Axie Infinity, each Axie is an NFT with unique characteristics.
Tokenized Economies:
Many on-chain games have their own tokenized economies, where in-game tokens can be used to purchase in-game assets or services.
Example: In Decentraland, players use the MANA token to purchase land and other virtual goods.
On-Chain Gaming Challenges
Scalability:
Public blockchains can face scalability issues, which can affect the speed and cost of transactions.
Solutions: Use of sidechains or second layer (layer 2) to improve efficiency.
Technical Complexity:
Developing and interacting with smart contracts and blockchain requires advanced technical knowledge.
Solutions: Use of platforms and tools that simplify the development and management of smart contracts.
Transaction Cost:
Transaction fees on blockchain can be high, especially during times of high demand.
Solutions: Optimization of smart contracts and choosing blockchains with lower fees.
Future of On-Chain Chain Games
The future of on-chain games is promising, with the possibility of:
Greater Interoperability: Players will be able to use their digital assets in multiple games and platforms.
Innovation in Play: The integration of emerging technologies, such as virtual and augmented reality, with blockchain.
Community Development: Communities of players and developers more involved in the evolution and governance of games.
