No it's not the same. OpTech is written by people and curated, while TLDR is AI-generated summaries of all the things.

OpTech is my go-to for specific topics that I want to dive deep into, and TLDR is how I get a bird's eye view of everything that has happened in the last week of the mailing list and Delving Bitcoin.

Yes, there is a newsletter! But if you don't want to sign up you can also visit to the website to browse mailing list summaries as you wish, as well as read past newsletters.

Oh hooray!!! Fill out the form and mention that we chatted here :) I’ll get some to you 😎

Do you have a local bitcoin meetup? I’d be happy to send some over! There’s a form on my website for non profits and educational groups. Fill it out! https://satsie.dev/zines

Oh thank you! I’m having issues with my Lightning Address in Zeus. Will try to fix this ASAP

Thanks for sharing on here!

Yes, it's a custom signet chain with one miner that's run by an admin.

To answer @Manikese's question, it would be a clean ledger

Really great visuals on this. Well done!

hi! do you mean the whole transaction signing series? you can find it all here: https://bitcoindevs.xyz/decoding/transaction-signing

It's 100% free and open source. I suspect @bitcoin_devs didn't post all of it because it is very long :)

You're very welcome!

I know what Base58 class you are talking about and that lesson is great! It's where I first learned about endianness :)

Most modern CPUs work in little-endian, so it was likely chosen as a performance optimization. According to this site, Learn Me a Bitcoin (https://learnmeabitcoin.com/technical/general/little-endian/#why-does-bitcoin-use-little-endian), it's because Satoshi developed bitcoin on a computer with little-endian architecture.

Thank you so much ^-^ I did! And thanks to OP for sharing!

Whoa! Thank you for including it in your wonderful collection of resources!!

Nice! Thank you for that!! Be sure to check out https://bitcoindevs.xyz for other educational projects in the same family as Saving Satoshi :)

Chapters 1 - 3 can be mostly done without a coding background, but the game does ramp up once you get to chapter 4. One feature we'd like to introduce is difficulty levels so the game is accessible to a larger group of people.

If you haven't already, I invited you to give chapter 1 a try. You should be able to complete it within 30 minutes, no background in coding required. Let us know what you think!

Thanks for sharing! This is the official release of the game, which has been in the works for 2+ years. Hope everyone enjoys it as much as we did building it! More updates to come in 2025 :)

You're correct! It's been in the works for 2+ years, which explains why it has occasionally popped up. However yesterday the tenth chapter was released, completing the story line and bringing the 1.0 release over the finish line.

There are still lots more updates to come, but yesterday was a big milestone. Thank you for sharing it!

The real reason is my son is obsessed with the movie Cars and the scene where Larry the Cable Guy introduces his character as “I’m Mater, like tomater, without the tuh!” lives rent free in my head 😭
