Psst. Don't have enough hours in the day to read the mailing list and Delving Bitcoin? We have a secret weapon for you.
Bitcoin TLDR has daily summaries, available by post or by thread: 
Here's today's summary of the bitcoin-dev mailing list:
- Ava Chow announced Bitcoin Core version 28.1. It makes adjustments to p2p configurations to enhance usability & reduce startup failures. It also has internal ID counting updates, enhancements in key handling, build system improvements, & a call for community participation in reporting bugs and joining the announcement list
- @Jameson Lopp raised concerns about the reliability of transaction timestamp data, specifically the vulnerability of nLockTime. It can be manipulated for unfair prioritization benefits, undermining the effectiveness of new prioritization rules.
- Yuval Kogman critiqued misconceptions around privacy mechanisms, focusing on wabisabi credentials & Wasabi wallet. He sheds light on the challenges with safeguarding privacy and security, emphasizing transparency, comprehensive security measures, & ethical considerations.
Bitcoin TLDR
Bitcoin tech mailing list summaries at your fingertips
The account model is like your bank statement. Simple to understand and works well with smart contracts. The downside is it's less private and can be vulnerable to replay attacks.
The UTXO model is like bills in a wallet. UTXOs (unspent transaction outputs) can only be spent once. Each transaction creates new UTXOs, and your balance is the sum of all your unspent UTXOs
This model has better privacy, prevents double spending, and allows for parallel transaction processing. The cons are it's more difficult to understand, is harder for complex applications, and requires UTXO management.
Here's a comparison chart of the two models:

How is Saving Satoshi different?
- Logged in state to remember your progress
- Ability to share accomplishments publicly
- A real story to motivate you to learn
- Free and Open Source
Saving Satoshi started as a hackathon idea:
“How can we make bitcoin tech education more engaging and fun?”
Since then it’s become a game with 10 fun chapters, and support for both Python and JavaScript
Worldwide there are groups like TabConf and Scalar School playing together.
Give Saving Satoshi a go today, and let us know what you think.
Shoutout to the team that helped bring this over the finish line

Being able to play with interactive elements to understand Bitcoin concepts is the best way to solidify a working mental model
No libraries allowed, you’ll craft everything from scratch!
We support both JavaScript and Python (of course!)
Each bitcoin concept comes with its own exercise, so you’ll learn not just how things work, but also when and where to use them.
By the end of each module, you’ll challenge yourself by creating a project to test your understanding.
We’ve started with the first module on Scripts.

Scope
The scope of the product is laser focused: bitcoin tech
Users can suggest sources deeper in the product. This bolsters our repo of bitcoin tech sources
We build pathways to scrape the data
Which grows our library of bitcoin tech literature and resources
Ecosystem of Knowledge Creation
Bitcoin Search thrives as a collaborative ecosystem.
As you do more Transcript Reviews and suggest new credible sources, our database continuously expands and improves, ultimately benefiting the entire Bitcoin technical community.
It’s a virtuous cycle of knowledge creation
We already had a live V1. Why build a V2?
We wanted to improve comprehension of the product for newer devs interested in bitcoin tech
While improving its usability, and increasing a sense of delight when using it.
