What is a full chain game?

Full-chain games refer to games andNFTimage description

In a full-chain game, all player behavior and data are recorded on the chain, not in the game server.

Traditional blockchain games have both smart contracts and game servers, while full-chain games only use blockchain and smart contracts.

Smart contracts can also be used to create, distribute and transfer digital assets. In the card game mentioned above, the digital asset is the trading card NFT. Digital assets are the most widely used technology in the field of blockchain games, including Gods Unchained, Axie Infinity, Illuvium, WildCard and DeadropNFT gamesfirst level title

Challenges faced by full-chain games

Blockchain Speed ​​and Scalability

scalabilityscalabilityThere is a bottleneck in terms of speed and scalability, two key technical elements for creating fast-paced games.

Transparent Player Operations

Smart contracts and transactions in contracts are completely transparent and can be viewed by anyone. Transparency is an advantage in financial scenarios, but it becomes a bottleneck in gaming scenarios because privacy cannot be guaranteed.

For example, the fog of war mechanics in MOBA games or real-time strategy games can hardly be implemented on the chain. Such games need to hide parts of the game from players. Of course, someTechnical solutionsto solveoccasionalsecondary title

technical bottleneck

Because blockchain and smart contracts are designed with security as the first priority, there are some technical bottlenecks that prevent certain tasks from being performed.

The two biggest bottlenecks of full-chain games are obtaining tamper-proof random numbers and automatically executing game logic.

• Almost all full-chain games must use on-chain random number solutions, and these random numbers are often manipulated by validators (or miners) in the network because they can see the random number before the chain is finalized.

• Some intermediate process operations in the game (such as transmitting a series of game logic based on player operations) need to automatically call smart contract functions to improve the game experience. But smart contracts and the blockchain alone cannot do this. For example, if a player has harvested an asset, the operation of automatically harvesting the asset must be initiated before the asset will appear in the player's inventory.

Advantages of full-chain games

Composable and open source

Since the full-chain game fully deploys the game on the blockchain, players and developers can reproduce the game logic, create a new game type, develop different interfaces for the game, and develop various applications based on the game to enhance the game experience , enhance the openness and entertainment of the game.

Decentralization, digital permanence and immutability

An often overlooked aspect of full-chain games is that they can essentially run automatically once deployed on-chain.

Both blockchain and smart contracts are essentially back-end technologies. If players want to play the purest on-chain game, they must use the command line to interact.

Dark Forest

Dark Forestis a relatively recent real-time strategy full-chain game set in space. This game is inspired by Liu Cixin's science fiction novel "Three-Body Problem - Dark Forest". Players are placed on an unknown Odaily in space. The task is to collect resources, expand the territory, and occupy the new Odaily.

The Development of Web3 Native Games

Full-chain games are relatively niche in the Web3 ecosystem, but there are still some community members, researchers and developers actively exploring the boundaries of full-chain games.
