I checked my Aztec on-chain history and found it's been over 1700 days. On March 15, 2021, Aztec officially released its protocol http:/zk.money, and I immediately deposited ETH into their protocol. I specifically checked my on-chain history at the time, and I was probably the 20th user on the entire network to perform a deposit. Of course, my motives weren't entirely pure. On one hand, I strongly support the development of privacy technologies; I was among the first to try both Tornado Cash and 0xbow. On the other hand, I genuinely hoped for airdrops for early adopters. At that time, the airdrop rewards were substantial, but I never intended to "farm" them; I just wanted to be a genuine, long-term, ordinary user. The gas fees were also staggering; the cost of a single on-chain transaction was greater than 0.01 ETH. Later, they launched Aztec Connect, which connects to DeFi, and I followed suit immediately; that was over 1200 days ago. 1️⃣ More Than Just "Coin Mixing" During this long wait, Aztec didn't remain stuck in the old "coin mixing" logic, but instead achieved a qualitative leap from "privacy tools" to "private world computers." Simply put, previously we could only achieve "anonymous transfers," but now Aztec aims to allow us to "anonymously use various applications." This solves a major pain point: we need smart contracts as user-friendly as Ethereum, but we don't want our pay slips, social relationships, and every transaction exposed to everyone. This "programmable privacy" is the truly missing piece in Ethereum's ecosystem. 2️⃣ The Noir Programming Language In ecosystem building, they did something akin to "road construction": the Noir programming language. Previously, developing privacy applications had an extremely high barrier to entry, like writing incomprehensible gibberish; now Aztec has lowered that barrier. This means that future privacy applications won't be limited to simple money transfers; more privacy-focused DeFi, privacy-focused voting, and even privacy-focused games will emerge. Only when developers find them useful will these applications truly flourish, and only then can ordinary users like us genuinely benefit. 3️⃣ Application Scenarios What truly makes me feel that privacy is no longer an abstract concept is the practical application of things like zkPassport. It has completely changed my preconceived notions about "compliance." Previously, to prevent witch hunts or conduct KYC, we had to send passport photos to project teams, posing a significant risk of data breaches. Now, through Aztec's technology, I only need to prove "I am a real person" or "I am an adult" on the blockchain, without needing to disclose sensitive information like my passport number or date of birth. It satisfies regulatory requirements while returning data sovereignty to ourselves—this is what new technology should be like. 4️⃣ Ignition Chain Another point that impressed me is Ignition Chain's commitment to decentralization. Unlike mainstream L2 blockchains which are often plagued by centralized orderers, Aztec established a decentralized verification architecture from the outset. This fundamental commitment to resisting censorship aligns with Vitalik Buterin's assertion that "privacy is health": elevating privacy protection from an optional "feature" to an indispensable "infrastructure standard" for blockchain networks. 5️⃣ Continued Support So when Aztec announced its collaboration with Uniswap to launch the CCA auction, I immediately jumped in. This time, I only made it into the top 50, a slight setback. Actually, the investment wasn't large; I simply wanted to see these truly hardcore technologies continue to grow in this volatile market.

Last cycle, everyone was very FOMO about this project.

Therefore, many new friends may not be familiar with it.

King-level project

If the market rallies again, privacy will likely regain market attention.

Just wait, I think it will get noticed sooner or later.
