Zero-knowledge proofs are one of the most exciting cryptographic innovations powering modern blockchain applications but understanding how they actually work can be intimidating. We’ve just published "How ZK Proofs Work – Part 1: Groth16", where we break down one of the most widely used zk-SNARK proving systems into simple, approachable concepts. • What Groth16 is and why it's popular • How proving and verification work at a high level • Why trusted setup matters • Where Groth16 is used in real-world applications https://lnkd.in/gr-Cg4uE

The internet was never built with a native payment layer. That’s finally changing with x402 : a protocol designed to enable seamless, machine-native payments directly over HTTP using stablecoins and AI agents. In our latest article, we break down: • What x402 is • Why it matters for AI-driven commerce • How it could reshape APIs, micropayments, and the future of the internet • The role of autonomous agents in the next generation of online transactions As AI agents become more capable, the need for frictionless, programmable payments becomes critical and x402 is emerging as one of the most important infrastructure layers to watch.

We’ve been exploring one of the most important shifts happening in finance today: programmable money. As money becomes more than just a medium of exchange and starts carrying logic, conditions, and automation it opens up entirely new possibilities for how businesses operate, transact, and build financial products. From conditional payments to real-time settlement, programmable money is redefining financial infrastructure. We’ve put together our thoughts, insights, and key implications in this article https://lnkd.in/gYkBqPnw Would love to hear your thoughts and perspectives!

AI can take you from idea to code in minutes. But speed without understanding comes with trade-offs: 1) Code you don’t fully understand 2) Hidden bugs & security risks 3) Weak architecture that won’t scale AI should accelerate engineering, not replace it. Here’s our take on the risks. https://lnkd.in/gUMGmmep

Building on Solana? Security matters. We’ve published a new article covering common Solana security pitfalls and how developers can avoid them while building smart contracts and dApps. If you're working in the Solana ecosystem, this is worth a quick read. https://lnkd.in/e8TavduR #solana #web3

We are thrilled to announce a significant milestone for the TECHFUND family. Our very first portfolio company, DogHuggy Inc., has officially joined the Petgo Group (Securities Code: 7140) through a strategic acquisition. DogHuggy holds a special place in our hearts. As our first-ever investment, we didn't just provide capital; we shared an office, debated product strategies until sunrise, and shaped TECHFUND’s identity as a "tech accelerator that runs alongside entrepreneurs." That legendary night when we worked through the dawn to launch the first version of the service remains the cornerstone of our mission: "To ensure every vision can greet its dawn." By joining forces with Petgo, a leader in pet healthcare e-commerce, DogHuggy is set to accelerate the creation of a comprehensive "Pet Life Platform." 🐾 At TECHFUND, we remain committed to supporting entrepreneurs throughout their entire journey—from the first line of code to successful M&A exits. Congratulations to Shogo Nagatsuka and the entire DogHuggy team on this incredible achievement! #TECHFUND #DogHuggy #Petgo #MandA #StartupExit #TechAccelerator #Entrepreneurship #PetTech

Zero-Knowledge (ZK) circuits are at the forefront of privacy, scalability, and trustless verification in modern blockchain and cryptographic systems. But with this power comes unique security challenges that every engineer, architect, and security practitioner must understand. In our latest article, we break down the most common pitfalls in ZK circuit design and importantly practical fixes and preventive strategies to help you build safer, more robust systems. https://lnkd.in/gi4PWQTp #zeroknowledge #systemdesign
