For 0-day, it would be nice to see protocols deploy a safe harbor contract
- Any one can send (or rescue) tokens
- Protocol can only withdraw 95% of what was sent
- Remaining 5% can be claimed by the sender
Groth16 - part 3 - witness consistency check
A random linear combination of polynomials u, v and w forces the prover to construct them correct (somehow).
How? next post
Notes

Groth16 - part 2 - Separating factor
Multiplying or dividing by a secret value forces the prover to use elements in the CRS only for the intended purpose

Private transfers are so hot right now, but how many of you understand how they actually work?
We got you covered with an easy explainer - so easy, you can show it to your grandma
Soon you'll be able to have private transfers live in @ambire

go learn.
clz - opcode to return number of leading 0s in a bit
Before clz
Binary search to find most and least significant bits
With clz
msb = 255 - clz(x)
lsb = 255 - clz(x & -x)
What's x & -x?

See Tamaswap for a good example of a “no free lunch” theorem that states nobody can steal user funds with any chain of actions

Been learning about ZK-SNARKs lately! The core ideas behind modern hash-based schemes are surprisingly accessible & elegant 🧙♂️
Partly to teach myself, I wrote a post explaining them from scratch for people like me without a deep math background:
xn--2-kmb.com/zk-snarks
Groth16
I will explain the complex equations in the future

> i think i should continue my learning and give it some time
Yup. Use your time to learn the craft that you enjoy.
> Strength
Topics that you deeply understand.
In your example, from Aave v3, I would look into Aave v3 integration, forks, copies on other chains
From what I've seen on x, all BBP have unpleasant experience for SRs
High submission fees, many duplicates, ghosting and dismissed as private known issues.
I would pick BBP by your interest, your strength and amount paid.

yBorg - Week 1 Day 2
Meet @0xFlint_, the newest yBorg mentor. A gigachad security researcher with a diverse background who spends his free time getting lost in massive Rust codebases. He share's his audit methodology and thoughts on AI in a new video.
Today’s yBorg assignment:
- Watch the vid
- Soak up the alpha
- 👉 Think about how you’d turn his process into an AI-assisted workflow
For those who are joining us online, share a diagram in the comments showing how you'd turn Flint's process into an AI-assisted workflow - we'll be sharing examples from the Discord later.
This whole week we are thinking about process, both human and AI. We'll be sharing lots of diagrams and examples throughout the week and by the end of the week, fellows complete a diagram of what they are building!
@0xFlint_ also hosted an AMA on the discord and we can continue that here in the comments if anyone has anything they'd like to ask.
Enjoy the vid and don't forget to share your diagrams and ask questions in the comments!
