You might be surprised by how much your home knows about you. Your TV. Your car. Your smartwatch. Even your kids' devices. Everyday technology can reveal more about your life than you realise. Take our interactive Your Day in Data experience to see what this could look like in a household like yours. 🔒 No answers collected. No data stored.

Different organisations. Different systems. Different failures, but one question connects them all: Why do we continue building systems where so much personal information can be collected, accessed and exposed without meaningful control by the people it belongs to? Privacy needs to be part of these systems' design, not just their security policies.

Did you know you can turn an old smartphone into an offline crypto signing device? 📱🔓 The @paritytech Signer introduced this approach to the @Polkadot ecosystem back in 2018, keeping private keys offline and signing transactions via QR codes. Today, the project lives on as Polkadot Vault, developed and maintained by @NovasamaTech. Find out more 👇

New on our blog: the story behind Catamarca On-Chain! 🏛️ After PBA brought together Argentina’s Norte Grande governors, a conversation with PBA founder Dr. @gavofyork sparked Catamarca’s interest in training its government. The result: more than 250 decision-makers trained by PBA faculty. 🔗 Read the full article: polkadot.academy/catamarca-o…

We rarely think about ownership when something is truly ours. You don't need permission to access your own home, open your own notebook, or speak privately with someone you trust. Digital life should work the same way. Privacy and self-custody are about making that principle possible online.

PBA's foundational expertise in blockchain protocol engineering is now part of the formal curriculum of Universidad Tecnológica Nacional (UTN), Argentina's largest public technological university. 🇦🇷 This is a milestone we're proud of: the knowledge at the heart of PBA is now taught within a public university degree, alongside UTN's faculty, to the engineers who will help shape Argentina's technological future. This semester, final-year Information Systems Engineering students at UTN Facultad Regional Córdoba are studying how blockchains are designed and secured at their core: protocol architecture, advanced cryptography and zero-knowledge proofs, crypto-economics and interoperability. Building on the university's focus on smart contracts and applications, the content prepares students to design the systems they work with. 🎓💡 The collaboration is part of a framework agreement with UTN's national Rectorate to advance blockchain education across its campuses nationwide, and follows Dr. @gavofyork's masterclass at UTN in November 2025. This is the kind of work we want to build with universities, and we look forward to expanding our long-term partnership with UTN in the year ahead.

“AI is, at its heart, less truth, more trust.” In this interview, Gavin Wood argues that AI increasingly requires us to trust systems we cannot fully inspect: their training data, their models, or how they arrive at their answers. He contrasts that with Web3, which he describes as “less trust, more truth”: systems where more of the underlying rules and activity can be independently verified. That idea is relevant to Polkadot Products. The goal is not simply to build more infrastructure, but to create products where users can rely less on opaque intermediaries and have stronger guarantees about what is happening underneath. As AI becomes more embedded in everyday life, the ability to verify the systems we depend on becomes increasingly important.
