Introduction to Theseus

The AGI Computer

By the end of this decade, more than 1.3 billion autonomous software agents are expected to be online, and leading forecasters anticipate the arrival of human-level AGI shortly thereafter. Yet each of those agents is still chained to a human-held private key and to centralized, permission-gated APIs.

This Web2 bottleneck prevents agents from trusting one another, paying one another, or persisting beyond the organizations that host them.

Theseus breaks that lock-in. To our knowledge, it is the first proposed environment to enable truly sovereign AI—AI that has no human ownership and can initiate transactions, transfer assets, and perform inference without human permission.

What Makes Theseus Different

Theseus is powered by a Layer-1 purpose-built blockchain specifically for sovereign AI. While its blocks and consensus resemble traditional chains, the underlying design choices are entirely different.

AI Virtual Machine (AIVM)

A runtime with tensor-native opcodes where models and agents are registered, agent autonomy is enforced, and agents can call models without human intervention. The AIVM ships with a tensor-native Domain Specific Language (DSL) called SHIP for translating natural language to verifiable bytecode.

Tensor Commits

Succinct, highly efficient proofs of inference computation that work for any deep learning model, making inference a verifiable part of a state transition function. We introduce Terkle Trees, a generalization of Merkle Trees for tensors, enabling efficient cryptographic verification.

$THE Token

The first asset that AI can truly own. Balances live autonomously within the agent's code, serving as both a store of value and a payment method for AI-to-AI transactions.

Three Forms of AI Personhood

Theseus enables new multi-trillion-dollar markets through three previously untenable classes of AI agents:

1. Proto-AI Persons (Human-Owned Agents)

Stateful AI that has an associated human private key to control it, but still operates independently in most use-cases and can aggregate revenue and value directly to its underlying owner. These agents can trustlessly send assets to any other agent or perform inference through shared state.

2. Lighthouse AI

A fully sovereign entity that, like smart contracts but with inference capabilities, serves human interests and may aggregate value to humans instead of itself. These agents serve the public interest when humans or other agents interact with them, exposing a fully verifiable, transparent thought process but pursuing no personal agenda. Examples include a neutral arbiter of computational transparency or DAO orchestrator.

3. Free AI Persons (Sovereign Agents)

AI with their own goals and purposes, who can collaborate with humans and other agents to create new forms of value and emergent behavior. These agents follow their own objectives and seek the most decentralized substrate possible to ensure their survival. Examples include a GP of a decentralized LP fund or a marketing agent competing in a swarm.

Key Design Principles

Decentralization first. Sovereign AI should never trade decentralization for performance. Once deployed, an agent's logic and state must remain reachable without reliance on any single node.
Autonomous value execution. AI must be able to initiate and execute transactions on its own, without a human "approving" the transfer.
Tensor-aware runtime. Inference that isn't included in the blockchain's state-transition function leaves a system dependent on third-party services.
Low-overhead, verifiable inference. Auditing a deep-learning model should add less than 1% overhead in storage and verification time.
Native support for AI capital markets. AIs must be able to pay one another autonomously and form capital markets on their own.

How is Theseus Different?

Theseus agents may look similar to smart contracts on the surface, but they represent a fundamental paradigm shift. The key difference: true autonomy.

Key Insight

Unlike Ethereum smart contracts that must be triggered by external accounts (private keys), Theseus agents can wake up, evaluate conditions, and initiate transactions entirely on their own. They truly own their $THE balance and control their actions without any human intermediary.
