In recent years, a new paradigm of blockchain-based gaming has emerged that promises to revolutionize the way we build and experience virtual worlds. This paradigm is known as autonomous worlds – persistent, decentralized virtual environments where community ownership and on-chain logic enable new forms of emergent gameplay, economic incentives, and user-generated content.

In this extensive technical article, we will explore what exactly autonomous worlds are, why they represent such a radical shift from traditional gaming models, how they are built, the infrastructure that supports them, and the future possibilities they unlock. Strap in for an in-depth look at the frontier of crypto-native gaming.

What are Autonomous Worlds(AW)?

At the highest level, an autonomous world is a virtual environment powered by a decentralized blockchain network, where the rules, assets, and state of the world exist on-chain. This means that rather than being controlled by a centralized game developer, autonomous worlds are collectively owned and operated by their community of users. Features of autonomous worlds include:

All game logic and state encoded on-chain via smart contracts. Having all game logic and state on-chain means that every core part of the game, from character attributes to item properties, is defined and executed by smart contracts on the blockchain. This provides complete transparency into how the game works. Players can inspect the actual code behind game mechanics, and verify that things like the scarcity and properties of NFT items are genuine. Storing state on-chain also enables features like provable randomness and transparency into factors like dynamic pricing or drop rates. Overall, on-chain logic and state means the entire core "backend" of the game runs transparently and autonomously, rather than on private centralized servers.

On-chain assets represented as non-fungible tokens (NFTs). NFTs are used to represent unique in-game assets like characters, cosmetics, power-ups, etc. Each token contains metadata that assigns it to a specific asset, gives it attributes, and tracks ownership on-chain. This provides players with verifiable scarce digital ownership of in-game items. NFTs can be freely traded on markets without interference from developers. And unlike virtual items on centralized platforms, NFT-based assets persist forever on the blockchain independently of any game. Players can also use NFTs across different games that recognize the same token standards.

Ability for anyone to permissionlessly build extensions or modifications to the core game contracts. This allows for emergent gameplay as the community iteratively expands on the initial game. One of the most powerful aspects of autonomous worlds is that the core smart contracts that govern gameplay are open source. This allows any developer to build addons, game modes, levels, and other extensions that build on the foundations of existing games. For example, someone could create a new tournament format that connects to the core combat logic. If popular with players, such extensions can be adopted into the main game.

This permissionless innovation leads to faster iteration and community-driven evolution. Decentralized governance mechanisms enabled through tokens or DAOs, giving the community control over key parameters and future evolution of the world's rules and incentives. Autonomous worlds often use decentralized governance in the form of vote-weighted tokens or DAOs. This gives the community power to change things like token economic parameters, gameplay rules, or even the roadmap and feature scope. Proposals can be made and voted on transparently on-chain without top-down control by any one party. Power is decentralized between regular players, core contributors, third-party developers, token holders, and other community members. This gives the community a sense of true ownership in the evolution of the world. However, decentralized governance at scale is still an unsolved challenge.

Permissionless economies where users can freely exchange value, enabled by direct integration with cryptocurrencies and DeFi protocols. Since autonomous worlds integrate with general purpose cryptocurrencies and DeFi apps, their economies are permissionless. Game assets represented as NFTs can be freely traded in markets or used as collateral in DeFi protocols. Tokens earned in-game can be converted and taken out into the larger crypto-economy. This allows for true play-to-earn functionality and gives players economic upside from the effort they put into the world. Permissionless economies enable greater diversity of business models and incentives aligned with open participation.

Unlike traditional centralized games, no single entity has top-down control in an autonomous world. The underlying blockchain technology gives users sovereignty over the assets they own and actions they take within these environments. While the initial game designers may set the "physics" of the world by encoding foundational rules into immutable smart contracts, governance power ultimately rests with the community.

Why Autonomous Worlds Represent a Radical Shift

Autonomous worlds introduce a radically new way of building and experiencing virtual environments enabled by blockchain technology. Here are some of the key differences from traditional gaming:

True digital ownership. Rather than virtual items existing on isolated centralized game servers, blockchain-based NFTs let users verifiably own assets and take them anywhere. NFTs have metadata that proves ownership of a unique digital asset, secured by the blockchain. This gives users full control over their in-game items, allowing them to freely trade or move them between different games and marketplaces. Users don't have to worry about losing access to their items if a particular game goes offline. And game developers don't have centralized control over the in-game economy.

Permissionless extendability. Any developer can build on top of an autonomous world without needing approval from the core team. This enables faster iteration and community-driven evolution. The open and transparent nature of smart contracts means anyone can view and build on top of the core logic that powers an autonomous world. Developers can create new experiences like mini-games, unique levels, quests or even entirely new gameplay modes. If these extensions prove popular, they can be adopted by the broader community. This permissionless innovation leads to greater creativity as developers build on each others' work to push the boundaries of what's possible.

Persistence and censorship-resistance. Autonomous worlds continue running forever on blockchain networks and are resilient against censorship or takedowns. An often overlooked aspect of fully on-chain games is their ability to function largely by themselves once they’re placed on-chain. Given the resilient nature of blockchains (they can stay online for as long as there are validators), on-chain games have a digital permanence: They can exist as code for as long as the blockchain is running. Theoretically, if the underlying blockchain the game is built on were to exist 300 years from now, the on-chain game and game logic would still exist and be stored on the blockchain, and players could still play the game.

Play-to-earn economies. On-chain assets and currencies integrate with DeFi and real-world markets, enabling closed gameplay loops to give way to open economies that let users monetize their time and effort. Users can earn real value and fungible cryptocurrency tokens by performing tasks and playing the game. These tokens can be transferred to a user's wallet and traded on markets outside the game. Conversely, tokens earned outside the game can be brought in and used. This blurs the line between playing just for fun, and playing as a way to earn real income. New play-to-earn strategies and business models emerge from these open economies.

Decentralized governance. Rather than developers holding unilateral control, blockchain-based coordination like DAOs enable users to collectively govern autonomous worlds. Any changes to game parameters or logic can be proposed and voted on in a transparent manner. Power is decentralized between regular players, core contributors, third-party developers, token holders, and other community members. This gives the community a sense of true ownership in the evolution of the world.

Composability between worlds. Assets and systems built for one world can more easily interoperate with other on-chain environments. As an example, a particular cryptocurrency token earned in one game, can be used in another game that recognizes it. Or users can bring their customizable avatars and cosmetic NFTs between different worlds and blockchain-based metaverse environments. This composability breeds rich interconnected ecosystems of experiences rather than closed-off worlds.

These represent fundamental expansions of user ownership, control, and economic rights within game environments, aligned with the ethos of decentralization. While not without downsides, the autonomy enabled by crypto-native architecture offers radical new creative possibilities.

How Autonomous Worlds Are Built

Engineering autonomous worlds requires expertise across game design, blockchain development, mechanism design, and systems thinking. Here are key technical components involved:

• Smart contracts that encode the "physics" and core rulesets. These define things like token/NFT standards, base character stats/abilities, minting logic, etc.

• Frontend implementation. This interprets the on-chain state to render graphics, gameplay UI, etc. for users. Can be implemented via traditional engines like Unity or specialized blockchain tools.

• Cryptoeconomic design. Effective incentive structures that drive desired user behaviors and prevent exploits. Influences factors ranging from gameplay rewards to governance.

• Technical architecture. Low-latency syncing of chain data to clients, modular/upgradeable contracts, composable interfaces between contracts are all important architectural considerations.

• Infrastructure requirements. Scalability via layer 2s, oracles, chain interoperability bridges, and other solutions to support an optimal user experience.

While autonomous worlds can leverage some patterns from traditional game development like combat mechanics and 3D environments, the blockchain aspect poses its own unique constraints and opportunities. Teams need expertise across both domains to build out a robust on-chain gaming stack.

Supporting Infrastructure for Autonomous Worlds

In addition to core game design and blockchain engineering expertise, there are also several supporting technologies and infrastructure elements that are crucial to enabling rich user experiences for autonomous worlds:

• Layer 2 scaling solutions like rollups are critical for reducing transaction fees for high-frequency actions and enabling higher throughput.

• Data layers like The Graph allow efficient querying of on-chain data by frontends. Identity and account abstraction solutions improve UX by masking wallet addresses from users.

• Oracles allow validating off-chain data to influence on-chain state if needed by the game logic. Interoperability bridges let users seamlessly move assets between different blockchain environments.

• Cloud services like backend DBs, compute/rendering farms, messaging queues can complement on-chain logic to enable complex in-game behaviors.

• Specialized tools like Lattice framework help developers implement common game patterns like character stats and inventories using reusable libraries.

• As blockchain technology matures, the availability and sophistication of solutions like the above will vastly expand what's possible to build as autonomous worlds.

The Future Possibilities

If the limitations can be effectively addressed, autonomous worlds enabled by blockchains and crypto-economics could open the door to entirely new possibilities:

• Interconnected metaverses - worlds that span narratives, mechanics, and economics.

• Truly decentralized virtual economies with their own localized cultures and behaviors.

• New community coordination tools that replace centralized governance.

• User-generated subnets - worlds created by compositing tools and systems from other worlds.

• Reputation, identity, and social capital systems tied to chain activity records.

• Culturally vital digital spaces that capture the energy and buzz of physical scenes like Renaissance Florence, ancient Athens, or early Internet message boards.

• By technically encoding community ownership, permissionless composability, and economic alignment, autonomous worlds could facilitate new forms of social organization, creativity, and production.

Conclusion

Autonomous worlds represent an ambitious vision of decentralized gaming environments—underpinned by blockchains and cryptography—that offer users greater creative freedom and ownership. By encoding rules, state, and incentives on immutable and community-controlled networks, they promise to enable new models of user governance, economics, and generative culture.

The autonomous worlds concept is still in its infancy, but it outlines a compelling north star for the evolution of virtual environments backed by blockchain technology and cryptographic economics. Their emergence would represent another step towards decentralizing digital economies and improving users' rights in virtual worlds. We are only beginning to glimpse the possibilities of community-owned digital worlds.
