370: FHE, Privacy, and the Future of On-Chain Transactions with Guest Speaker Guy and Kate from Fhenix

I sat down with Guy and Kate from Fhenix to talk about something that's been missing from crypto since day one: real privacy. They're building a privacy co-processor using Fully Homomorphic Encryption (FHE) that lets you compute over encrypted data without ever exposing it. We covered why privacy is finally getting product-market fit, how institutions need confidentiality for payments and DeFi, and why AI agents will need private transactions. Guy shared his journey from Intel's Trusted Execution Environments to building Fhenix, and Kate explained why encryption should be the default, not an afterthought. We also talked about their shift from L2 to co-processor, their integration with Ethereum, Arbitrum, and Base, and what's next for confidential smart contracts. If you've ever wondered why everything in crypto is public by default and how that's about to change, this episode is for you. CONNECTFhenix Website: https://fhenix.ioFhenix Twitter/X: https://twitter.com/fhenixioWeb3 with Sam Kamani - Be a Guest: https://www.web3pod.xyz/KEY POINTS Guy's background at Intel building Trusted Execution Environments and his transition to founding FhenixKate's journey from cybersecurity engineering to crypto and why she sees it as the new Wild WestWhy Fhenix pivoted from building an L2 to a privacy co-processorWhat Fully Homomorphic Encryption (FHE) is and how it enables computation over encrypted dataPrivacy use cases in payments, DeFi, dark pools, and sealed-bid auctionsWhy institutional adoption requires confidentiality, not just anonymityHow AI is improving FHE performance and lowering barriers to entry for builders• [00:00] The importance of private agent-to-agent payments in the AI era• [00:00] Why developers should learn fundamentals even in the age of AI coding tools• [00:00] Fhenix's roadmap: faster cryptography, more chain integrations, and enterprise partnerships• [00:00] Their incubator program and call for builders to experiment with privacy-first smart contractsDisclaimer:Nothing mentioned in this podcast is investment advice and please do your own research.
