You can order X, do you dare to let me verify the cards? The most annoying thing when the market comes is a bunch of people shouting orders. They don't post their wallets after shouting, and even if they post, they don't know where they belong... In short, don't just look at what someone says, but more importantly, look at what they do. The question is, how do we view it in blockchain? In the past, it was easy to measure how much a person said. If asked, is what X said consistent with what they actually did off chain? Who dares to answer? Let's sneak in! ⬇️ Is Kaito resurrected? I didn't pay much attention, but I received several invitations from friends to update my Arua score. At first glance, I realized that I needed to install a plugin. Just don't steal my wallet anymore... It wasn't until I saw the boss @ xxiong-xie Twitter saying that Kaito's new feature Pulse is powered by Primus that I was surprised, which was interesting. To understand what Primus does, you can start with the Kaito resurrection feature Pulse. Yap has been popular for over a year and has also made Kaito the hottest project. Essentially, it is about recording what users say and how influential they are on social media, known as "Attention". Yap is a numerical expression. Later on, Yap fell, and one of the fundamental reasons was that you only shouted about the project results and didn't even participate, brother? Trust not only includes what you say, but also consistent actions. However, the difficulty at that time was Kaito's inability to complete 'Behavior verification'. Behavior verification, especially cross platform behavior data verification, also needs to be able to be calculated on the blockchain. This thing has a bit of technical content and requires a professional team to do it. The inconspicuous line "Powered by Primus" on the Kaito Pulse page and the founder's private mention of zkTLS are the real key. Primus allows users to prove their true identity and historical performance on trading platforms, AI services, and predictive markets without exposing any raw data. When all eyes are fixed on the lively front-end, it is often the person who silently turns trust into infrastructure that truly changes the rules of the game. So, I installed the Kaito plugin and aligned the data. Today, I had 1253 Auras ranked 41st globally and 10th in Chinese, which made me feel vain again... This is still a situation where many of my data have not been verified. PM, I verified my performance, emm， Did you deduct points? After some exploration, I roughly understood the role Primus played in the entire ecosystem. I tried to summarize three technical features as a weekend science popularization. ZkTLS - Behavior Verification Without Exposing Raw Data The Web3 project calls out real users and behaviors every day, but most of them can only see what X says, making it difficult to confirm whether this person has really traded on Binance, used on a certain AI platform, or bet on the prediction market. The traditional approach is either to fully trust centralized interfaces or to have users hand over all their private data. Primus' solution is to allow users to generate a zero knowledge proof locally through a browser plugin, stating 'I do have a certain account/behavior on a certain website', but without disclosing the original data such as account passwords, balances, transaction records, etc. to anyone. Kaito collaborated to incorporate Primus' zkTLS into the Pulse browser plugin. Users can verify their real accounts and historical performance on trading platforms, AI services, predictive markets, etc., unlock Aura scores, and qualify for campaigns. Previously, there was only a Yap score for 'speaking too much', but now there is a validation layer for 'words spoken are consistent with actual behavior'. By the way, Primus' zkTLS performance is one order of magnitude higher than the industry benchmark Chainlink's Deco, and it has also received a grant from the Ethereum Foundation. FHE - Privacy Computing Truly Available Even if the real data is verified, it is still difficult to use after being put on the chain. Credit scores, asset proofs, and transaction behavior are too sensitive. Directly putting them on the chain is like running naked, and traditional encryption cannot calculate them directly. Primus' solution is FHE+zkFHE. I have previously explained about fully homomorphic encryption (FHE), which allows data to be computed in an encrypted state and decrypted after computation. Primus further developed zkFHE to prevent malicious behavior by computing nodes. For example, if a lending agreement wants to use users' off chain credit/behavior data for risk control, but does not want to see the original data, it needs to use a solution like zkFHE. In fact, Primus has already launched Confidential Finance, where the project team creates a Proof of Reserve to prove the health of funds in a lighter and real-time verifiable way, rather than just providing a static audit report. Pure technology, especially when it comes to cryptography, is not something that ordinary teams can handle. Apart from industry giant Zama, Primus is one of the few teams with independent research and development capabilities throughout the entire process from algorithm design, engineering implementation to productization. The founder has made early contributions to FHE's key technology, which is very strong. Primus has also successfully become a privacy partner of BNB Chain. Oh yes, he is also a member of Ezi Residency S4 and has received investment from @ yzilabs. From verification to a complete closed loop that is usable Primus is not just selling a zkTLS plugin or FHE library, but building a complete pipeline for real data on chain, privacy protection computing, and practical application implementation. After checking the official website, the current product lineup includes browser extensions, developer Dev Hub, users' own Web3 profiles, social red envelope payments, Proof of Reserve, and more. When InfoFi, real influence, off chain credit, and privacy DeFi become the next stage of essential needs, the infrastructure that can simultaneously address data authenticity and data privacy computing will become very scarce. Primus already has real commercial clients, support from the Ethereum Foundation, BNB Chain collaboration, and complete delivery capabilities from cryptographic algorithms to products. That's it, it deserves a respect. To sum up, the blockchain can only trust its own data in the past, and @ primus_labs enables the real world on the Internet to be connected to the chain safely and privately, and truly calculated and used. Kaito Pulse is the first case seen, and you can install a plug-in to go through it without pain or trace.
