The architecture of AI systems is undergoing a transformative shift toward decentralization, moving away from traditional cloud models centralized around hyperscalers such as AWS, Azure, Google, and Oracle. This shift is driven by the increasing power and sensitivity of AI in handling information, particularly in critical sectors like government, healthcare, and finance. The need for enhanced security, privacy, and user control is pushing the development of decentralized AI, which leverages distributed networks to process and store data, reducing reliance on single points of failure and mitigating risks of data breaches.
For consumers, this could mean running multiple specific AI agents—potentially 5-10, or even 20—for personal tasks such as health monitoring, financial planning, and social life management, all while maintaining control over sensitive data. This approach contrasts with the centralized models of Web 2.0, where companies like Google, Facebook, and YouTube have been criticized for mining user data for profit, offering free services like email in exchange for extensive data usage, particularly for advertising. The concern is that giving such entities access to personal data in the AI era could lead to a form of "digital slavery," undermining user autonomy and privacy.
Blockchain technology emerges as a cornerstone for enabling this decentralized AI ecosystem, offering solutions for two distinct use cases: machine-to-machine (M2M) commerce and decentralized identity. These use cases are pivotal for realizing the vision of a secure, user-centric AI landscape.
Machine-to-Machine Commerce (M2M)
M2M commerce involves AI agents autonomously transferring value between each other, which could be in the form of NFTs, digital tokens, or digitized currencies like the euro or U.S. dollar. This concept is rooted in the growing interconnectivity of devices in the Internet of Things (IoT) and the need for secure, efficient transactions without human intervention.
Blockchain facilitates this by providing a decentralized, transparent, and secure network for conducting transactions, eliminating the need for intermediaries and reducing costs. Smart contracts, self-executing agreements with terms written in code, ensure that payments are executed only when specific conditions are met, enhancing trust and automation.
For example, an AI agent managing a user's finances could pay another AI agent for booking a flight or purchasing goods, using digital tokens, with the transaction recorded on an immutable ledger for transparency. This is particularly relevant in sectors like connected cars, smart homes, and industrial automation, where devices need to interact and transact autonomously.
The integration of M2M payments is anticipated to shape the digital economy, leveraging technologies like 5G and blockchain to enable secure, efficient processes. To develop this further, standardized protocols could be established for AI agents to negotiate and execute transactions, creating decentralized marketplaces where agents offer and consume services. These marketplaces would use digital tokens for payments, ensuring security and efficiency through smart contracts.
The challenge lies in scaling these systems to handle high-throughput processing, as M2M interactions are seen as the next frontier in decentralized commerce.
Decentralized Identity
The second use case, decentralized identity, addresses the need to verify on-chain that the AI agent one is interacting with is authentic and authorized. Decentralized identity, often referred to as self-sovereign identity (SSI), allows individuals or entities to control their digital identities without relying on central authorities, using blockchain for security and verifiability.
Key components include:
- Decentralized Identifiers (DIDs): Unique, user-controlled identifiers
- Verifiable Credentials (VCs): Cryptographically secure digital representations of credentials like passports or certificates
- Digital Wallets: Secure storage enabling sharing and verification without exposing unnecessary details
For AI agents, this means each agent can have a unique, verifiable identity, crucial for establishing trust in interactions, especially in sensitive contexts like financial transactions or healthcare data management. This approach reduces the risk of identity theft and data breaches, as data is not concentrated in a single vulnerable location, with 2023 statistics showing 75% of security professionals reporting increased cyberattacks compared to the previous year.
Lukso's Universal Profiles
Lukso's Universal Profiles exemplify this use case, offering interoperable, blockchain-based identities designed for the new creative economies, including fashion, gaming, and social media. Launched on Mainnet in November 2023 and surpassing 20,000 profiles by June 2024, Universal Profiles are built on standards like LSP0-ERC725Account, LSP6-KeyManager, and LSP1-UniversalReceiverDelegate, providing a modular, upgradable identity system.
They use ERC725Y for data storage and LSP3-Profile Metadata for profile information, enabling economic and verifiable interactions. For AI agents, Universal Profiles can serve as their digital identities, allowing them to present verifiable credentials to prove authenticity and authorization, enhancing trust in decentralized interactions.
The mobile app Alpha and The Grid, launched in November 2024 during Devcon in Bangkok, further improve accessibility and functionality. This aligns with the need for robust identity verification in decentralized AI.
To develop this further, integrating Universal Profiles or similar solutions into AI agent frameworks could enable seamless identity management, with mechanisms for agents to obtain and present credentials. Ensuring user-friendly verification processes that maintain privacy is key, addressing concerns about data control and reducing reliance on centralized authorities.

Conclusion
The move toward decentralized AI, supported by blockchain's role in M2M commerce and decentralized identity, addresses critical concerns about data privacy and control, particularly in sensitive sectors. Platforms like Lukso, with its Universal Profiles, offer innovative solutions for identity management, enhancing trust and security in AI interactions.
Developing standardized protocols for M2M transactions and integrating robust identity systems will be key to realizing this future, ensuring users are empowered in the digital economy while mitigating risks of exploitation. The shift from centralized to decentralized AI represents not just a technological evolution, but a fundamental reimagining of how we interact with intelligent systems in a way that preserves human autonomy and dignity.
