What's Blockstream up to Larry Nahum ~ Understanding Bitcoin Apr 24, 2019

Show notes

To make Green the best it can be, we’ve rebuilt the iOS and Android applications from the ground up. Based on the new Green Development Kit (“GDK” - more on this soon!), Green has been optimised for speed and performance, while the interface has been completely redesigned to provide the user experience people expect from a top-tier Bitcoin app. We’ve retained the same multisig security that our existing users know and love, while packing in a whole host of advanced features that should get our power users excited. https://blockstream.com/ Understanding Bitcoin conference is organized with a focus on the non-technical, non-developer users that want to increase their knowledge and technical participation in the Bitcoin network.

Cryptographic Vulnerabilities in Threshold Wallets ~ Omer Shlomovits ~ Breaking Bitcoin Apr 22, 2019

Show notes

Cryptographic Vulnerabilities in Threshold Wallets. In the talk I will discuss threshold ecdsa signatures in the context of a wallet. In terms of cryptography this is a "wild wild west" and I will exemplify this using series of pitfalls and errors done by engineers and cryptographers, where eventually I show how a small misuse of cryptography broke an implementation of a threshold wallet completely. Finally I give some tools to implementers that wish to go down this path anyway. The talk is highly technical and low level but hopefully self contained. Breaking Bitcoin is an event for the technical community focusing on the security of Bitcoin and everything around it. Presentations aim to be technical, focusing on vulnerabilities, theorical or practical attacks targetting the users and the Bitcoin protocol. This event is geared toward people with knowledge of the technical aspects of Bitcoin or security in general. https://breaking-bitcoin.com/ If you have learned something valuable, donate a couple sats to Max as a thank you note: 3DqEnU6dW6bZesrVdThrrQjQKgN7dpY5vv https://tallyco.in/HillebrandMax Support the show by buying bitcoin on https://hodlhodl.com/join/ERCT

For a New Liberty ~ Bitcoin Reading Group Apr 22, 2019

Show notes

In For a New Liberty: The Libertarian Manifesto, Rothbard proposes a once-and-for-all escape from the two major political parties, the ideologies they embrace, and their central plans for using state power against people. Libertarianism is Rothbard's radical alternative that says state power is unworkable and immoral and ought to be curbed and finally abolished. To make his case, Rothbard deploys his entire system of thought: natural law, natural rights, Austrian economics, American history, the theory of the state, and more. It is relentless, scientific, analytical, and morally energetic—a book that makes an overwhelming case. Indeed, it gave an entire movement its intellectual consciousness and earned Rothbard the titles "Mr. Libertarian" and "The State's Greatest Living Enemy." https://mises.org/library/new-liberty... https://bitcoinreadinggroup.com If you have learned something valuable, donate a couple sats to Max as a thank you note: 3DqEnU6dW6bZesrVdThrrQjQKgN7dpY5vv https://tallyco.in/HillebrandMax Support the show by buying bitcoin on https://hodlhodl.com/join/ERCT
