EPISODE

Episode 83: The Milk Sad Vulnerability

In this episode, Aaron (@AaronvanW) and Sjors (@provoost) discuss a vulnerability in Libbitcoin dubbed “Milk Sad”, which allowed people to generate private key seeds with such weak entropy that their private keys could be brute forced and their coins stolen. Aaron and Sjors examine how this vulnerability (could have) ended up in Libbitcoin as well as in Andreas Antonopoulos’ book Mastering Bitcoin, to what extent it should be considered a bug, and more.For more information on Milk Sad, see: https://milksad.info/Libbitcoin lead developer Eric Voskuil on Milk Sad: https://youtu.be/3uwl5xDdc7c Sjors New Book: https://www.amazon.com/Bitcoin-Technical-innovations-Sjors-Provoost/dp/9090360425 THIS EPISODE’S SPONSORS: ⁠Voltage Cloud⁠ ⁠Bitcoin 2024 Nashville⁠ ⁠Bitcoin Magazine⁠ ⁠Bitcoin Amsterdam⁠ Lower your time preference and lock-in your BITCOIN 2024 conference tickets today!

"high quality" is not good enough though. The term I should have used is Cryptographically Secure. Anything less is unsafe for Bitcoin: https://en.m.wikipedia.org/wiki/Cryptographically_secure_pseudorandom_number_generator

It's strange: my node has buckets of inbound capacity and is connected to some large entities, yet boosts do sometimes fail. Hopefully things improve over time.

Episode 82: Scaling to Billions of Users

In this episode, Aaron (@AaronvanW) and Sjors (@provoost) discuss a recent blog post by Bitcoin Core developer Anthony Towns (@ajtowns), “Putting the B in BTC”, in which he outlines a vision for scaling Bitcoin to facilitate billions of users. As Aaron and Sjors walk through the article, they explain what some of Towns’ proposed solutions are, and which tradeoffs they entail.Link to the blog post: https://www.erisian.com.au/wordpress/2023/06/21/putting-the-b-in-btc Sjors New Book: https://www.amazon.com/Bitcoin-Technical-innovations-Sjors-Provoost/dp/9090360425 THIS EPISODE’S SPONSORS: Voltage Cloud Bitcoin 2024 Nashville Bitcoin Magazine Bitcoin Amsterdam Lower your time preference and lock-in your BITCOIN 2024 conference tickets today!

Witness data is stored in blocks. They're fysically located at the end so that pre-segwit nodes can ignore it, but otherwise they're really just part of the block. If a node prunes a block, then the witness data is gone. It's not possible to prune the UTXO set (without something like Utreexo). So in that sense they're quite different.

EPISODE

Episode 79: The Witness Discount

In this episode of Bitcoin, Explained, Aaron (@AaronvanW) and Sjors (@provoost) explain why the witness discount was included in the Segregated Witness protocol upgrade from 2017, why this discount is 75%, and why this discount still makes sense in today’s world where Inscriptions benefit from it.

I don't care about NFT's. If someone want to make an irreversible NFT that's fine with me. I don't think it's possible and Ordinals / Inscriptions don't achieve this. There's no scarecity. You can't copy-paste my UTXO and have more money, but you easily copy my JPEG. The only scarecity is copyright, but the chain doesn't enforce that.

For the password manager, now that you have a keyboard, the user could just type the domain and it can display a (deterministic) password. Make it mnemonic like passwords that are quick to type. Bonus points for allowing user override passwords that are stored on the SD card.
