Jutta Steiner, the CEO and co-founder of Parity Technologies, discusses “The Evolution of Blockchain Security.” Steiner, who joined the Ethereum team in 2014 as chief of security, says the advent of that open ecosystem of interdependent “smart contracts,” or self-executing design programs, opened a whole new attack surface that requires successful organizations to prioritize a security-minded culture. Potential coding risks include memory safety, input validation, privilege escalation flaws, fundamental design flaws, side channel attacks and cryptographic vulnerabilities such as insecure key storage. Security is not just code, however — it’s also people, operational procedures, and life cycle management of applications. There is no single answer to any of these vulnerabilities, Steiner says. Instead, mitigation relies on a range of measures that are not perfect but can be used to create an overall system that is very difficult to penetrate. The key is to understand that crypto development is not like agile software development — once deployed, code is difficult to recall, and security must always be at the forefront. She closes by noting that crypto developers can learn from security approaches used in other industries, such as aerospace, medicine, and hardware.

Andreessen Horowitz’s Crypto Startup School brought together 45 participants from around the U.S. and overseas in a seven-week course to learn how to build crypto companies. Andreessen Horowitz is partnering with TechCrunch to release the online version of the course over the next few weeks.

It seems like every big AI player is building a personal agent. Meta has Muse, OpenAI launched Dots, and a startup called Instinct recently raised $1 billion at a $10 billion valuation. But Eugenia Kuyda thinks the next generation of AI assistants needs to do more than book your restaurant reservations and find you hidden money in your Gmail.

Kuyda, who founded AI companion app Replika, has just launched Wabi, a personal AI agent that organizes your life into separate conversations, brings other people into the mix, and builds custom apps around what you’re trying to do. The idea is to make AI less of a solo productivity tool and more of a way to spend time with the people who matter to you.

On this episode of TechCrunch’s Equity podcast, Rebecca Bellan talks with Kuyda about why she thinks AI agents should bring people together instead of keeping them glued to a single chatbot, how Wabi plans to compete in a crowded and expensive market, and what it takes to get people comfortable giving an AI access to their email.
