8 min readJun 16, 2024

AI and blockchain have each made significant strides in reshaping industries and societal functions. AI has brought profound advancements in productivity, creativity and automation, while blockchain has introduced great security and transparency in data transactions. But these technologies are often seen as opposites, where no intersection is possible. On the contrary, these technologies can bring new paradigms of digital trust, privacy ownership and portability, leading to a new era of decentralized intelligence. This article attempts to delve into how the fusion of AI and blockchain is not just enhancing existing capabilities but is also forging new pathways for innovation, privacy, and user empowerment.

Centralization vs. Decentralization

AI and Crypto are often seen as opposing forces in the tech landscape. AI often centralizes control by aggregating data and decision-making power within a handful of tech companies, which helps in refining algorithms and improving service delivery. On the other hand, crypto advocates for decentralization, where control and decision-making are distributed across multiple nodes or users in a network, reducing the power of central authorities.

AI processes, especially those involving large models like those used in deep learning, require significant computational resources, which can be at odds with the more resource-efficient, lean processes favored in blockchain technologies. Finding a balance where AI can operate efficiently on decentralized platforms without compromising performance or increasing costs is a key tension point.
Similar can be said for decentralized governance, which can be used to oversee AI initiatives. Such governance structures are complex and can be in conflict with the current model of centralized decision-making in AI development and deployment.

However, these technologies also show potential synergies. For example, cryptographic techniques can enhance AI applications by providing secure, decentralized ways to manage and compute on large datasets without compromising user privacy.

Blockchain’s inherent characteristics of decentralization, immutability, and transparency can be employed to create secure environments for AI data processing. For instance, using blockchain to log and verify AI decisions can provide an audit trail that ensures accountability and transparency.
Crypto technologies enable the creation of decentralized marketplaces where AI services and data can be exchanged or sold in a decentralized way, reducing costs and improving access for many players with less resources.

How can we decentralize AI?

Blockchain can facilitate the decentralization of AI with concepts like smart contracts and zero-knowledge proofs. These can help ensure that AI operations are verifiable and transparent, without exposing individual data points to risk.

Smart Contracts: Smart contracts are self-executing contracts with the terms of the agreement directly written into lines of code. In the context of AI, these contracts can manage the rights to use AI models, handle licensing, or automate the execution of certain AI-driven decisions without human intervention. Example: A smart contract could automatically compensate data providers when their data is used to train an AI model, ensuring fair distribution of profits generated from AI insights.
Zero-Knowledge Proofs (ZKP): Zero-Knowledge Proofs allow one party to prove to another that a statement is true without revealing any information beyond the validity of the statement itself. This can be crucial for AI in maintaining privacy when processing data. Example: ZKP can enable private machine learning, where AI models can be trained and predictions made without ever exposing the underlying data. This is crucial for handling sensitive information like medical records or financial transactions. However, ZKP can be used to obtain proof of the type of data used to train the model or what type of model was in fact used to make the predictions.
DAOs: DAOs are organizations represented by rules encoded as a computer program that is transparent, controlled by organization members and not influenced by a central entity. DAOs can be used to govern AI projects, where decisions on developments, updates, or data usage are made collectively by stakeholders. Example: A DAO could oversee a decentralized AI project, allowing participants to vote on updates, models used or data integration, ensuring the development aligns with the collective interest of all contributors.

The long-term impact of the decentralization of AI could lead to more equitable access to these technologies and reduce the risk of monopolistic control over them. It also could ensure that AI benefits are more broadly distributed across society.

Decentralized AI could lead to a surge in solutions tailored to diverse, global needs rather than the priorities of those who control the technology.
Better transparency on data used to train AI models and added ownership to personal data used to fine tune or query AI models.

Applications and Innovations

One innovative approach in the use of AI is to automatically generate or verify smart contracts. AI can help streamline the creation of these contracts, ensuring they are both efficient and less prone to human error.

Automated Compliance and Enforcement: AI can analyze vast amounts of data to ensure that the terms of smart contracts are being met and can trigger actions automatically when conditions are fulfilled. This automation can help reduce human error, making processes faster and more efficient.
Dynamic Adaptation: Smart contracts can be designed to utilize AI to adapt their rules or execution logic based on external data or performance outcomes. This dynamic adaptation could be used in fields like supply chain management, where contract terms may adjust automatically based on inventory levels or delivery times monitored by AI systems. Such flexibility allows for more responsive business models that can better cope with changes in the market or operational conditions.
Personalized AI Services: In services and entertainment, AI can analyze user preferences and behaviors to tailor experiences which are then managed and billed through smart contracts. For example, a media streaming service could use AI to curate content personalized to the viewer’s taste (e.g.: Spotify’s new AI Playlists) and use a smart contract to handle subscription fees, content licensing, and royalty distribution automatically. This integration ensures users receive highly personalized services while creators and service providers are compensated quickly and in a transparent way.

Challenges

Deep Fakes & Copyright Infringement: One of the challenges with AI is AI-generated content that may impersonate someone or create content based on someone else’s, infringing copyright law.

Blockchain, however, can be used to verify the authenticity of digital content, providing a robust defense against deep fakes and copycat content. By maintaining a secure, immutable ledger of digital content and its origins, blockchain technology can help confirm if content has been tampered with or fabricated. This system can be used by news organizations, content creators, and social media platforms to verify the source of content before publishing or sharing, reducing the spread of fake information.
Moreover, blockchain can facilitate Digital Rights Management (DRM) by helping control the distribution and access to digital media. Smart contracts can enforce the terms under which content can be viewed, copied, or shared, and manage the rights of different stakeholders involved in content creation, from authors to distributors. This ensures that unauthorized distribution and manipulation of media, such as deep fakes, can be controlled more effectively, protecting intellectual property and reducing fraud.

Data Privacy: Both AI and blockchain handle vast amounts of data, raising significant privacy concerns. The integration of these technologies must ensure that personal data is protected and potentially encrypted.

For example, we’ve seen the controversy with the music industry claiming that AI products have been trained with copyrighted material without the permission of the rights holder. This will continue to be an increasingly challenging problem as more content is used to train models other than plain text.
One way to use blockchain to curb this problem is to use zero-knowledge proofs and homomorphic encryption to allow AI systems to process data without ever exposing the underlying data content. This means AI can learn from data or make decisions based on data that remains encrypted throughout the process.
Decentralized data storage can prevent the risks associated with central data repositories, which are prime targets for hacking and data breaches. This can make data harder to access by unauthorized parties.
Lastly, blockchain provides a transparent and immutable ledger of all transactions, which can be applied to track and audit data usage in AI systems. Therefore, any access or use of data can be verified and traced, providing users with greater confidence in how their data is handled. This can prove to be very useful in sectors with stringent regulatory requirements for data handling, such as finance and healthcare, ensuring compliance and building trust with users

Governance Models: Blockchain can also play a pivotal role in the governance of AI with the use of DAOs, Algorithmic Transparency and Smart Contracts.

DAOs can be used to make sure everyone has a say in the control of AI systems, allowing users, developers, and other stakeholders to vote on key decisions, such as updates to algorithms, model training or data usage policies. Such idea promotes a more democratic approach, allowing more voices to be heard in the governance process.
Blockchain can help establish governance models that ensure transparency and accountability in AI algorithms by recording all changes and decisions related to AI systems in a transparent way. This includes who made what changes, under what authority, and based on which data.
Smart contracts can be programmed to automatically enforce certain governance actions within AI and blockchain systems. This could include the execution of updates only when certain conditions are met or when approved by a majority in a voting process.

Future Visions

Blockchain has the potential to help us control the data AI is trained on and has access to for any actions made. If this is implemented right, AI has the potential to be the ultimate tool to assist us in our daily lives and empower users to gain control over their data and AI applications. Here’s a few thoughts on what the future might be under this assumption:

AI as Personal Assistants: AI personal assistants could evolve from simple task managers to complex adaptive systems that learn continuously from their interactions with users. Integrating these AI assistants with blockchain technology could ensure that all personal data used by the AI is secured and controlled by the user. Blockchain could be used to manage access rights to personal data, where transactions of data access are recorded transparently, ensuring that the user’s consent is required for data access.
User Empowerment and Control: Users could own their AI assistants, much like any other personal property. This ownership implies not just control over how the AI is used but also how it evolves over time, its settings, and its interaction protocols. By leveraging blockchain, decisions about updates, data sharing, and even the ethical guidelines followed by AI systems could be made in a decentralized manner. Users could participate in collective decision-making processes about the development and functioning of the AI systems they depend on.
Portability of AI: These AI agents could not only be customizable but also portable across different platforms and devices. Blockchain could facilitate this by providing a universal and secure way to store AI configurations and learning, which can be accessed across various interfaces. Such interoperability enhances user convenience and ensures that personal AI assistants can be a constant presence, providing seamless support regardless of the platform or device in use.

As we stand on the brink of a new technological frontier, the integration of AI and blockchain continues to unfold with promising potential. The synergy between AI’s analytical power and blockchain’s decentralized framework is paving the way for more secure, transparent, and equitable digital environments. From creating lifelong personal AI assistants to establishing robust defenses against deep fakes, this convergence is setting the stage for a future where technology operates with enhanced responsibility and in closer alignment with human needs. However, the journey ahead is not without challenges. Ethical considerations, governance models, and the balance of power in decentralized networks remain critical areas for further exploration. Embracing these challenges with innovative solutions will be crucial in fully realizing the transformative impact of AI and blockchain on society.
