I’ve always loved building things that help others build. In case you missed it, we have announced Yaru.Create, an initiative that shows anyone how to start a business using AI — from idea to first customer. We’re living in a rare moment. AI gives anyone the tools to create. Social media gives anyone a voice. Together, they open the door to a new kind of entrepreneurship. It reminds me of the days before the industrial revolution — when having your own small business was normal. When people created things, traded them, and made a living on their own terms. I’ll be joining the first Yaru.Create cohort myself. I want to see what it’s like, on the ground with everyone else. This is a big step for COTI. The COTI tech stack will be part of the course, so people can build real things on web3. By doing this, COTI gets to connect with the next wave of builders — from everywhere. I want to be clear: my focus on COTI is as strong as ever. I see this initiative as a way to bring more people into the COTI ecosystem, not as something separate. At my core, I’ve always wanted to be an enabler and an explainer. That’s what this is about — helping more people become builders again. create.yaru.ai/ @COTInetwork $COTI
Got a big idea? Don't just dream it, build it! Introducing Yaru, a new initiative empowering the next generation of creators to turn their dreams into reality. Yaru gives you the tools and techniques, guidance and support to go from idea to launch - no code or crypto experience needed!

Every cycle, money flows to infrastructure before applications. 2017: Smart contracts 2020: DeFi primitives 2025: Privacy layers The infrastructure for confidential on-chain finance is being built right now. Those paying attention won't miss it twice.
When one of crypto's most influential investors makes privacy his #2 bet, that's not a trade. That's a thesis. Privacy isn't a feature for the next cycle. It's the infrastructure that unlocks the next trillion in on-chain value. RWAs, DeFi, AI agents all require Programmable Privacy The capital is waking up to this reality. $COTI
🚨JUST IN: ARTHUR HAYES BETS BIG ON ZCASH! BitMEX co-founder says $ZEC is now the 2nd-largest holding in his family office Maelstrom, behind only #Bitcoin.

People in Yaru Create starting to use @COTInetwork as a private backend (CRM). Real world privacy at speed and cost efficiency is starting to enable a largely unexplored new use case for Web 2.5.
We solved transparency in money. Now we have the opposite problem. Every transaction. Every balance. Every interaction. Public by default. This isn't just a crypto issue. It's why RWAs can't move on-chain without privacy infrastructure. The solution exists: Programmable Privacy on public ledgers. Visible sensitive data on-chain is a bug, not a feature. @COTInetwork $COTI

Privacy shouldn't be tribal. Privacy coins → new ecosystem, new tooling Privacy layers → same code, new capabilities That's why composability matters. Build once, add privacy as a parameter. That's the path to adoption. @COTInetwork

We're living in a rare moment. The entire industry is converging on one realization: Privacy is infrastructure, not a feature. Look at the signals: Vitalik pushing privacy toolkits Major exchanges adding privacy support Institutions demanding confidential settlement Privacy tokens rallying 750%+ The market is saying: we need this. But here's the question nobody's asking: How do you build privacy that scales to billions of users? Not through complexity. Through simplicity. Developers coding in Solidity. Users getting privacy by default. Enterprises getting compliance without compromise. That's the unlock. That's what @COTInetwork enables with gcEVM. Programmable privacy on Ethereum. Fast. Light. Composable. The infrastructure is ready. Time to build.

Imagine a PRIVATE PERP DEX @PriveX_Official @COTInetwork
Privacy just got a whole lot easier. We now support @Zcash Orchard Unified Addresses Orchard lets users send and receive ZEC privately. Hiding the sender, receiver, and how much was sent. It’s built on Halo 2, a faster and more secure cryptographic system than before. Unified Addresses keep things simple by combining private and public ZEC payments into one address.

The privacy coin surge isn't just about price. It's the market recognizing what we've been building toward: Financial transactions need confidentiality. But privacy coins solve only part of the problem. They hide transfers. But we don't want to just send value privately. We want to build privately. What about private computation? What about DeFi with confidentiality? What about enterprise workflows on-chain? First came privacy coins. Now comes Programmable Privacy. $COTI @COTInetwork
The Ethereum privacy ecosystem is accelerating. RAILGUN for ZK-based privacy. Different tools for different use cases. This is healthy ecosystem development with multiple approaches being tested and integrated. What matters now: Making these tools composable. Making them fast enough for real applications. Making them accessible to developers who code in Solidity. That's the vision behind gcEVM. Privacy-preserving smart contracts that work with existing Ethereum infrastructure. We're all building toward the same goal: making privacy default, not optional. @COTInetwork $COTI $ETH $RAIL
Been watching $RAIL for a while. Ethereum-native privacy protocol built for stealth mode. Balances and transactions stay hidden. Bull thesis: 1. @VitalikButerin & the @ethereumfndn are integrating Railgun into the Kohaku privacy toolkit. 2. $RAIL jumped ~300% post-announcement—on-chain vote of confidence. 3. Solves two core problems: privacy on public chains & institutional-grade multisig via ZK. Founder goes by “Emmanuel Goldstein” (Orwell’s enemy of the state + legendary hacker alias). His last tweet was in 2021. Feels prophetic now. Bullish.

At my core, I'm a builder enabler. And I want to be clear about something: Sensitive data on-chain is a bug, not a feature. Not in 2017. Not in 2025. Not ever. That's why programmable privacy isn't just nice to have. It's the missing piece. @COTInetwork $COTI

Yes: AI + blockchain convergence makes privacy mandatory, not optional. Here's why: Proprietary models need protection Training data has value Inference results contain business logic All of this requires confidential computation at scale. We're seeing this already with @COTInetwork builders: AI agents executing private transactions. Models running on encrypted data. MPC enabling multi-party AI workflows without revealing inputs. The technical challenge isn't just encryption. It's making it fast enough and light enough for real applications. That's where Garbled Circuits come in. $COTI
Privacy is evolving from promise to practice. Activate built-in privacy for your application, enforce ownership, control access, and run blockchain-verified compute.

Started building Privacy for Web3 two years ago because Privacy is inevitable and then around July predicted that we'll have a Privacy Summer in Q4 this year. We're fully prepared and our time is now. @COTInetwork $COTI
Get ready for Privacy Summer! ☀️ Transparency is great, but let’s be honest, some things should stay private. Even on-chain. That future starts now with COTI. Privacy isn't a feature, it's the foundation of a new era → Explore Privacy 2.0: coti.io $COTI
If Zcash is Bitcoin but secret COTI is Ethereum but secret $COTI $ZEC $BTC $ETH
Privacy in crypto has evolved through three phases. First came privacy coins. They delivered anonymity - hiding who transacted with whom. Then came ZK proofs. They brought secrecy of inputs - proving you know something without revealing it. Now comes programmable privacy. The ability to choose what stays private and what stays public, at the application layer. This is the unlock. Because here's the thing: enterprises don't need everything hidden. They need selective confidentiality. A trading desk wants to hide its strategy but prove compliance. A healthcare app needs private patient data but transparent audit trails. That's what programmable privacy enables. And that's what Garbled Circuits through @COTInetwork delivers. Developers can now write privacy parameters directly into their Solidity code. Choose what to encrypt. Choose what to reveal and to who. All on-chain, all composable with the rest of DeFi. We're moving from privacy or transparency to privacy AND transparency. The next wave of applications won't be built on anonymity. They'll be built on choice. $COTI

Privacy Narrative is Heating Up Privacy coins like $ZEC, $DASH, and $XMR kicked things off, but they only show portion of privacy transactions. The next evolution? 👀 It’s Programmable Privacy by @COTInetwork It enables: ✅ Smart contract logic ✅ Cross-chain workflows ✅ Selective disclosure ✅ Institutional auditability. COTI = fast, programmable, and compliant privacy which is the missing piece for mass crypto adoption.
The UK is rushing digital ID without proper safeguards. coindesk.com/opinion/2025/11… This is exactly why decentralized alternatives matter. Centralized identity systems create: Single points of failure Surveillance infrastructure Data breach risks Blockchain-based identity solves this differently: User-controlled credentials. Selective disclosure (prove age without revealing birthdate). No central database to breach. Privacy-preserving identity requires: Cryptographic proofs (not databases) On-chain verification (not central authorities) Confidential computation (Garbled Circuits enable this) This is one of the killer use cases for Web3. Not speculation. Real infrastructure for digital rights. The technology is ready. The need is obvious. Now comes the builders. @COTInetwork $COTI

Bitcoin gave us digital scarcity. Ethereum brought programmability. Solana proved throughput at scale. Privacy is what comes next. But not all privacy tech is equal. ZK hides inputs. MPC with Garbled Circuits hides the computation itself. That's the difference between concealing what you searched for vs hiding that you searched at all. We're building the latter at @COTInetwork. Programmable privacy that scales on Ethereum. The next wave isn't about hiding data. It's about computing on it without revealing anything.
