Blockchains are powerful, but they have one important limitation: they cannot independently verify everything happening outside their networks. Think about how much useful information already exists on the internet. Financial records, exchange balances, trading history, payment records, professional achievements and data from different online platforms. Many Web3 applications could benefit from this information, but accessing it reliably creates a challenge. How can a smart contract know that information received from an external website is genuine? And how can users prove something about their online activity without exposing their private account information? This is where @primus_labs comes in. Primus uses zkTLS to connect information from Web2 platforms with Web3 applications through cryptographic verification. How does it work? Let's break it down. 1. Retrieving external information A user accesses a supported website, such as a financial platform, where relevant information already exists. 2. Verifying the information Primus uses zkTLS to generate cryptographic evidence that connects the information to its original web source. This helps applications verify that the submitted information is authentic rather than simply trusting a screenshot or manually entered figure. 3. Protecting user privacy Instead of exposing an entire account or sharing unnecessary personal information, users can generate proofs of selected information. 4. Connecting it to Web3 The resulting proof can be used by applications to verify specific claims and support decisions within blockchain-based systems. Let's look at a real-life example. Imagine a DeFi lending platform that wants to assess a user's trading history before offering them a loan. The user's trading activity exists on a centralised exchange, but the lending platform operates on a blockchain. Without a reliable verification mechanism, the user might have to submit screenshots or share sensitive account information. With Primus zkTLS, the user can potentially prove selected information about their trading history without exposing their complete exchange account. The lending application receives cryptographic evidence it can verify. This creates a bridge between information stored on traditional internet platforms and applications operating in Web3. Why is this important? It opens possibilities across several sectors: - DeFi: Verify external financial information for lending and eligibility assessments. - Digital identity: Prove selected online achievements and credentials. - Prediction markets: Verify information from external sources. - AI applications: Provide verifiable web information for AI-driven decisions. - Reputation systems: Make achievements from different platforms useful across Web3. What makes this particularly interesting is that Primus isn't asking the entire internet to move onto a blockchain. It's working on ways to make existing internet information verifiable and useful within decentralised applications. My takeaway: The next stage of Web3 won't depend only on what happens on-chain. It will also depend on how reliably applications can access and verify information from the world outside the blockchain. That's the infrastructure @primus_labs is working to build. Web2 has the information. Web3 has the applications. Primus is helping connect the two through verifiable data.
