PLONKish arithmetization is the constraint framework used in the PLONK polynomial IOP. It's the approach used to turn computations into polynomial constraints that a proof system can verify. Heard the term before but never really understood what "PLONKish arithmetization" actually means? In Episode 5 of my series 🎬 I break it down step-by-step. Check it out here: youtube.com/watch?v=9CWS1H…

@_Z561 How are you approaching it?

@ProgrammerSmart But with a slightly different approach

I Saved Injective's $500M. They Pay Me $50K. I like hunting bugs on @immunefi . I'm decent at it. - #1 — Attackathon | Stacks - #2 — Attackathon | Stacks II - #1 — Attackathon | XRPL Lending Protocol - 1 Critical and 1 High from bug bounties (not counting this one) Life was good. Then I found a Critical vulnerability in @injective . This vulnerability allowed any user to directly drain any account on the chain. No special permissions needed. Over $500M in on-chain assets were at risk. I reported it through Immunefi. The next day, a mainnet upgrade to fix the bug went to governance vote. The Injective team clearly understood the severity. Then — silence. For 3 months. No follow up. No technical discussion. Nothing. A few days ago, they notified me of their decision: $50K. The maximum payout for a Critical vulnerability in their bug bounty program is $500K. I disputed it. Silence again. No explanation for the reduced payout. No explanation for the 3 month ghost. No conversation at all. To be clear: the $50K has not been paid either. I've seen others share bad experiences with bug bounty payouts recently. I never thought it would happen to me. I can't force them to do the right thing. But I won't let this be forgotten. I will dedicate 10% of all my future bug bounty earnings to making sure this story stays visible — until Injective pays what I deserve. Full Technical Report: github.com/injective-wall…

@EChinagozim Have you tried solidity-by-example.org

@ProgrammerSmart Any rich lessons to comprehensively digest solidity I am aware of cyfrin , I find it difficult to understand

Like or dislike? Prefix storage variables with $

@hanzceo what is a scarab?

@ProgrammerSmart can you try using scarab?

@hyper0x0 @PatrickAlphaC agree

@ProgrammerSmart Prefer the s_ like suggested by @PatrickAlphaC tbh

@EChinagozim Namespace for storage variables without clever code like this #L106" target="_blank" rel="nofollow noopener">github.com/OpenZeppelin/o… After a little experiment, I concluded that it was indeed confusing since Solidity creates read only functions for public state variables, these functions will have $ prefix.

@ProgrammerSmart Explain please

@ADPthegreat Yeah, it reminded me of PHP

bro is reinventing php from first principles

This is probably the lowest I've been since a few years. Can't find freelance work, was super close of getting a good job in a startup in Switzerland, I failed B2B sales, and I don't know how I'll pay rent this month. Worst of all: my second baby is coming next month. I did tons of outreach that I should have started earlier. But it'll likely won't bring any result for at least a month. So yeah, if you're looking for a senior developer with 10+ years of experience (18 in total, 13 as a pro), tons of skills, Laravel + ecosystem expert, LLMs expert, design expertise, business expertise, etc. Feel free to reach out.
