The post is about the concept of 'Safe browsing'. Safe browsing claims to protect users by providing them with something called k-anonymity. Recent security news suggests that the k-anonymity has failed at protecting user privacy in certain circumstances. This is the topic that Trail of Bits explores in the blog post.

Dan Boneh on the past, present & future of cryptography

In this, our special 100th episode of the Zero Knowledge Podcast, we caught up with Dan Boneh, professor and researcher in applied cryptography and computer security at Stanford. In this far-reaching conversation, we talk about Dan's background in the field of cryptography, how the field has evolved over the years, his work on cryptography & blockchain education, where zero knowledge research and SNARKs in particular fits into the field, some exciting new research coming out of the Applied Cryptography Group at Stanford, what cryptographic and engineering problems he thinks we should be focused on solving, and more. This episode covered a lot of ground and even though we went overtime, there is still so much more to talk about. We hope to have Dan back on the show sometime soon!

TEEs, SGX and the Graphene project

In this week's episode we chat with two of the people behind the Graphene project, Chia-Che Tsai of Texas A&M University and Golem developer Lukasz Glen, about TEEs, Intel® Software Guard Extensions (Intel® SGX), and the way the Graphene project aims to make it easier for devs to interact with these hardware enclaves.Graphene started as a research project at Stony Brook University, led by Chia-Che Tsai and Don Porter, about emerging hardware platforms. In 2015, Intel Labs recognized the potential for Graphene to be an open-source compatibility layer for Intel® SGX, and has contributed to Graphene development since. With Golem and Invisible Things Lab (ITL), the Graphene project has also been now used within a decentralised blockchain context. The security around TEEs is a hotly debated topic (at least in our community) and we delve into the questions around these with our guests. That said, we do see this as the first of a series of episodes where we explore the challenges and advantages of using TEEs. https://grapheneproject.io/Thank you to this week's sponsor Apograf!

Getting Radicle with Julian Arni

In this week's episode, we speak with Julian Arni about Radicle, a decentralized alternative to Github built on IPFS. Radicle is both a programming language and a set of tools to enable decentralised open source software development. We go deep into this project, it's hope to impact open source development and also touch on the societal questions that inspired it. Here is a short tweet that summarizes it well.

Digging into DAI with Rune Christensen from Maker

In this interview, we chat with Rune Christensen from MakerDAO about stablecoins, MakerDAO’s take on this concept, the peg and how this is maintained, security, oracles and more. Here are a few of the terms that we discuss in the episode: DAI: a crypto asset-backed token pegged to the USD — it is designed to maintain a stable value.MKR: Valuebearing, tradeable token. As a governance token, MKR holders have the responsibility of making risk based decisions that will influence the future health of the system.CDP: The MakerDAO Collateralized Debt Position (CDP) is a smart contract which runs on the Ethereum blockchain. It is a core component of the Dai Stablecoin System whose purpose is to create Dai in exchange for collateral which it then holds in escrow until the borrowed Dai is returned.The best resource we found to explain the CDP is here: https://medium.com/cryptolinks/maker-for-dummies-a-plain-english-explanation-of-the-dai-stablecoin-e4481d79b90Thanks again to this week's sponsor Neufund.

Bridges, xDai and Burner Wallets with Igor & Austin

In this week’s episode, we sit down with Igor Barinov from POA Network and Austin Griffith from Gitcoin Labs to discuss bridges, xDai - the new side-chain where DAI is the native token - and Austin's super simple Burner Wallet.Bridges are a wide topic and with this conversation we try to give some insight into what they are and how they work. We look at xDai as one concrete example of such a bridged side-chain and Austin talks about his burner wallet that can provide a super snappy nice UX thanks to running on this faster side-chain.A few resources to check out: Burner Wallet website and Github RepoxDai WebsiteAs mentioned in the intro, the Zero Knowledge Summit is happening on March 22 - if you are a dev, researcher or founder working on these topics and want to attend, please submit your application here: https://goo.gl/forms/e0DpeHO6kyPVMlIg2)If you like what we do: Follow us on Twitter - @zeroknowledgefmJoin us on Telegram - https://t.me/joinchat/B_81tQ57-ThZg8yOSx5gjASupport our Gitcoin Grant - https://gitcoin.co/grants/38/zero-knowledge-podcastSupport us on Patreon - https://www.patreon.com/zeroknowledge Or directly here: ETH: 0xC0FFEE1B5083230a5154F55f253B6b6ae8F29B1aBTC: 1cafekGa3podM4fBxPSQc6RCEXQNTK8Zz
