Alex Puig is a Web3 entrepreneur and blockchain developer best known as the founder and CEO of Context Protocol, a project focused on organizing and verifying real-world information for use in decentralized applications and AI-driven interfaces. His work is closely tied to themes such as data sovereignty, semantic standards, privacy-preserving verification, and interoperability between on-chain systems and the broader web.
Overview
Puig’s public profile centers on building infrastructure that treats data as a first-class asset, with ownership, provenance, and permissions that can be verified cryptographically. He is commonly associated with research and development around zero-knowledge proofs, self-sovereign identity, and privacy-oriented architectures that aim to reduce dependence on centralized platforms for identity and information management. He has also contributed to industry discussions about how blockchain-based verification could support trustworthy AI outputs and agent-driven user experiences.
History and Background
In biographical information shared publicly, Puig has described more than a decade of experience in blockchain development, with a focus on privacy, decentralized identity, and data integrity. He is also linked to earlier ecosystem-building efforts in Spain, including initiatives such as Fintech Barcelona and the Digital Currency Summit. Another recurring reference in his background is his involvement in the Alastria Blockchain Ecosystem, a Spanish consortium-oriented initiative, where he has been described as helping coordinate participation from large institutions such as major banks and public sector stakeholders.
Puig has also stated that he launched a Web3 data venture studio with an initial budget of €300,000, later expanding it into multiple data-focused blockchain startups. This venture-style approach has informed his emphasis on reusable primitives, open standards, and product design that can be integrated into many different applications rather than a single vertical.
Context Protocol and DNS3
Puig leads Context Protocol, which has described itself as an AI-ready, decentralized semantic name service intended to organize and verify real-world data in Web3 storage. The project’s messaging has emphasized replacing conventional DNS assumptions with on-chain primitives that can identify, structure, and verify information, including entities such as organizations, locations, credentials, and documents, in a way that can be consumed consistently across applications.
The DNS3 branding associated with Context Protocol has been presented as an on-chain DNS concept for a new internet, where names and identifiers are not only resolvable but also semantically meaningful and verifiable. In this framing, context is not limited to locating a resource, it also includes metadata and verification signals that help systems decide whether the resource can be trusted.
Technology and Features
Puig’s work on Context Protocol is commonly discussed in terms of semantic data, verified knowledge graphs, and interoperability. The core idea is that data should be structured so it can be interpreted by many systems without bespoke integrations, while also being anchored to verification mechanisms that reduce the risk of tampering or spoofing. This approach is related to long-running Web3 design goals around portable identity and user-controlled data, topics covered in CryptoSlate’s overview of self-sovereign identity.
A recurring theme in Puig’s commentary is that AI systems need stronger guarantees about the provenance and integrity of the data they consume. Instead of relying on scraping and trust by reputation, he has argued for verification layers that can support sensitive use cases, including scenarios where private data should remain private while proofs of validity can still be shared. This aligns with broader industry interest in privacy-preserving verification techniques, including zero-knowledge proofs.
Use Cases and Market Position
Context Protocol’s positioning places it in an infrastructure layer between traditional databases, decentralized storage, and application interfaces. Potential use cases discussed publicly include verified business information, public registries, and sector-specific knowledge graphs that can be queried by software agents. In a CryptoSlate SlateCast episode, Puig discussed municipal-style examples where local business information, such as operating hours or menus, could be updated by owners and surfaced through chat interfaces, rather than maintained through centralized directories. Related discussion is captured in Redefining data sovereignty: Alex Puig on blockchain and AI interoperability.
For crypto-native applications, verifiable data and semantic standards can complement existing primitives such as oracles, especially where the challenge is not only fetching data but also establishing provenance, versioning, and update rights. Context Protocol’s emphasis on “AI-ready” data also places it near the broader AI sector narrative, where agentic interfaces and automated workflows increasingly intersect with digital assets.
Other Roles and Ecosystem Involvement
Puig has been publicly associated with additional ventures and advisory roles, including Caelum Labs, The Data Venture, and Rand Network. These roles are often described as adjacent to his work on data, identity, and Web3 infrastructure, reinforcing a pattern of building across multiple layers of the stack, from technical architecture to ecosystem development.
Risks and Considerations
Projects centered on verified data and semantic naming face adoption and governance challenges. Achieving interoperability requires standards that developers actually implement, and verification systems must balance openness with protection against spam, impersonation, and conflicting claims. There are also privacy and compliance considerations when dealing with real-world information, especially if the system is intended to support regulated industries or government-linked datasets. Finally, the long-term viability of any data layer depends on how it integrates with storage networks and incentives, including decentralized storage primitives such as Arweave, without assuming a single chain or provider will dominate.
Relevance to the Broader Crypto Ecosystem
Puig’s work matters to crypto markets because reliable data, portable identity, and verifiable context are recurring bottlenecks for mainstream adoption. As AI-driven interfaces become a common entry point to on-chain services, infrastructure that can provide trustworthy, machine-readable context may influence how users discover, evaluate, and interact with digital assets and Web3 applications.
