Web3 Wasn't Designed for Humans; It Was Built for Machines

Smart contracts, decentralized networks, and verifiable computation will remain. But now they are being optimized for AI-driven execution, coordination

Web3 wasn't designed for humans at scale; it was built for machines. Its complexity has limited adoption, but the "Post Web" stack is taking shape with AI agents emerging as autonomous economic actors.

Smart contracts, decentralized networks, and verifiable computation will remain. But now they are being optimized for AI-driven execution, coordination, and intent-based automation.

The question isn't whether it's happening but how fast we need to adapt.

For the past decade, we have been beta-testing decentralized systems and applications. While millions of people engage with blockchain networks, DeFi protocols, and decentralized applications (dApps), the reality is that Web3 remains vastly underutilized.

Despite approximately 10% of the world allegedly owning crypto, only a fraction of these holders actively use decentralized applications as a real alternative to Web2 or centralized platforms. This disconnect isn't due to a lack of capability in Web3 technology, but rather its usability challenges and inherent complexity.

In hindsight, Web3 was never designed for human users at scale. It was designed for machines.

Now, with AI agents emerging as autonomous economic actors, the sleeping giant of Web3 functionality is waking up. The "Post Web" - a term we coined at Outlier Ventures - creates a world where agents execute tasks, manage assets, and transact on our behalf. Every component of the Web3 stack will be repurposed. Once hindered by complexity, the infrastructure built for a decentralized world is now ideally suited for an internet optimized for machines.

AI agents will not just use Web3. They will unlock all of its potential.

The Giant Awakens

Web3 has been misunderstood. Many expected it to be a more decentralized version of Web2, where users own their assets, participate in governance, and interact with permissionless applications.

In practice, Web3 has revolutionized back-end systems. As yet, its technology remains too complex for the average user to handle. Smart contracts, self-custody, and bridging across chains require time, effort, and technical understanding that most people simply don't have.

This is where AI agents change everything. Unlike humans, agents thrive in complexity. They can process vast amounts of information, automate intricate workflows, and operate seamlessly across decentralized networks. While human users struggle with onboarding, agents can directly integrate with smart contracts, optimize for efficiency, and execute transactions without friction.

For the first time, Web3 will have users who can fully leverage its capabilities. AI agents will seamlessly interact with decentralized infrastructure, allowing Web3 to operate at the scale it was always meant to.

The Post Web Tech Stack: Built for Machines

Web3 has spent the past decade building decentralized infrastructure without considering AI. With the rise of autonomous AI agents, our thinking about this stack must fundamentally change.

In the Post Web, where autonomous AI agents replace humans as primary users, the stack undergoes two critical transformations:

In our broader work at Outlier Ventures on the Post Web, we've examined this evolution in greater detail. Put simply, the Post Web stack consists of three core layers, each essential for enabling an internet optimized for machines.

1) The Agentic Layer: AI as the New Interface

In the Post Web, users won't have to navigate wallets, exchanges, or dApps themselves; AI agents will do it for them. These agents act as personalized digital intermediaries, executing transactions, managing assets, and making complex economic decisions.

For this to work, the Agentic Layer will be the bridge between intent and execution. Users will express intent-based, high-level goals and objectives, such as investing in assets, booking travel, or negotiating contracts, and agents will handle the rest.

Smart wallets will evolve into sovereign identity hubs, storing personal data, assets, and permissions, allowing agents to act with precision. This shift means that instead of relying on centralized platforms, individuals will delegate actions to sovereign AI, giving them complete control while eliminating the need for direct interactions with complex systems.

The agentic layer is the largest green-field opportunity for bold founders who have the desire and ability to combine probabilistic AI capabilities with deterministic smart contracts and DLT. There is a need for marketplaces, coordination layers, frameworks, and more, all of which need to be developed and improved.

2) The Trust Layer: Smart Contracts & DLT as the Backbone

If AI agents are to execute real-world tasks, they need deterministic, verifiable environments where transactions and agreements can be enforced without ambiguity. This is where blockchain and smart contracts become critical.

Today's AI models operate on probabilistic logic. Based on training data, they predict the next most likely outcome. However, economic transactions require certainty and enforceability: a bank transfer, legal contract, or trade must be executed with absolute finality.

Smart contracts provide this missing piece. They offer immutable, self-executing agreements, allowing AI agents to conduct economic activity with complete transparency and verifiability
