Web3 Developer Underground Israel

​​MEV is the hidden tax on every DeFi trade - and AMMs are ground zero. But what if transaction ordering itself could be redesigned to be fair by default?
​💥 Join us for a deep technical dive into CLVR ordering - a mechanism that rethinks how AMMs sequence transactions, eliminates sandwich attacks by design, and fundamentally changes the economics of front-running.
​If you're building or auditing DeFi protocols, this one goes straight to the core of how value actually flows on-chain.

• ​​Date: Wednesday, May 13th
• ​​Time: 10:00 EDT | 16:00 CET | 17:00 Israel Time
• ​​Where: Streaming Live on X (Twitter), YouTube, and LinkedIn.

🎤 Meet the Experts

• ​Dr. Nir Chemaya | Assistant Professor @ Ben-Gurion University

🔬 What We're Breaking Down:
​⚙️ CLVR Ordering Explained: What it is, why it matters, and how it departs from first-come-first-served transaction sequencing.
​🥪 Sandwich Attacks - Anatomy of the Problem: How arbitrageurs exploit mempool visibility, and why standard AMM designs are structurally vulnerable.
​📐 The Math Behind Fair Ordering: Batch auctions, uniform clearing prices, and the tradeoffs between fairness, latency, and throughput.
​🔁 CLVR vs. Existing Solutions: How it stacks up against commit-reveal schemes, encrypted mempools, and MEV-auction approaches like SUAVE.
​🏗️ Protocol Design Implications: What CLVR ordering means if you're building an AMM, aggregator, or intent-based trading system today.

Web3 Devs Underground - Online Session
🎙 Root of Trust & Bearer Asset Inheritance
Brought to you by Israel Web3 Developers Underground × Papervault
Powered by Masterkey VC
Join us for an online deep-dive session with Boaz Bechar, open source developer at papervault.xyz, exploring one of the most critical - and underexplored - challenges in Bitcoin self-custody: how do you securely pass on a bearer asset without compromising it while you're still alive?
Boaz will walk through the cryptographic foundations of Root of Trust and practical approaches to inheritance planning for bearer assets - no trusted third parties required.
🎤 Speaker: Boaz Bechar (@boazeb) - Open Source Developer @ papervault.xyz

​Privacy in Web3 isn't just a feature - it's a fundamental design challenge. Zero-knowledge proofs are one of the most powerful cryptographic tools to solve it. But how exactly does ZK enable privacy without breaking verifiability?
​💥 Join us for a technical deep-dive into how ZK enhances privacy - unpacking the cryptographic mechanics behind zero-knowledge proofs and their real impact on Web3 applications, from identity to DeFi to infrastructure.
​If you're building privacy-preserving protocols or just want to understand the math and architecture behind ZK, this session is built for you.

• ​📅 Date: Wednesday, June 10th
• ​🕐 Time: 10:00 EDT | 16:00 CET | 17:00 Israel Time 🇮🇱
• ​📍 Where: Streaming Live on X (Twitter), YouTube, and LinkedIn.

​🔬 What We're Breaking Down:
​🔐 ZK Proofs 101: The cryptographic foundation - what it means to prove knowledge without revealing it.
​🕵️ Privacy by Design: How ZK shifts the trust model in on-chain applications - from transparent-by-default to private-by-default.
​🏗️ ZK in Practice: Real use cases across identity, DeFi, and data integrity - where ZK adds the most privacy value today.
​⚖️ Tradeoffs: Computational cost, proving time, and the engineering decisions builders need to make.
​🔁 ZK vs. Other Privacy Approaches: How it compares to mixers, confidential transactions, and TEE-based solutions.
