ETH Vietnam 2024 Speaker and Sponsor Announcements

Linea has launched Season 2 of Linea Insights, featuring Youssef El Housni discussing gnark, an open-source zero-knowledge library written in Go. **Key Points:** - First episode titled "What is gnark?" introduces the widely-used proving library - gnark is one of the most deployed ZK proving libraries in production - Season 1 concluded with coverage of Linea's transition from zkEVM to RISC-V zkVM The new season will provide an in-depth exploration of gnark's capabilities and applications across the ecosystem.

A misconfigured integration created standing approvals that could have drained user funds. Phylax Systems' Credible Layer security integration successfully intercepted the threat. **Key Prevention Metrics:** - $44,653 in confirmed user losses prevented - 4,000 drain attempts blocked - $1.5M+ in cumulative drain volume neutralized **How It Works:** Drain transactions are evaluated and rejected during the block building process, preventing them from ever reaching inclusion on-chain. All protected smart contracts remain untouched and secure. The integration demonstrates how proactive security measures at the sequencer level can identify and stop exploits before execution, rather than responding after damage occurs.

Linea has published an update to its documentation page. The zkEVM rollup's technical documentation is available at docs.linea.build for developers building on the network. **Key Points:** - Documentation refresh for Linea's developer resources - Updates available on the official [Linea Docs](https://docs.linea.build/) page - Follows previous documentation updates from earlier this month Linea continues to maintain its technical documentation for developers working with the zkEVM scaling solution.

Phylax Systems CEO Odysseas will discuss the evolution from reactive to proactive security approaches in DeFi during an upcoming conversation. **Key Details:** - **Topic:** The Credible Layer and its implications for builders and DeFi security - **Date:** Thursday, January 29th - **Time:** 3:00 PM UTC - **Platform:** X and YouTube - **Hosts:** suzapolooza_eth and EricCMack Several protocols including Euler Finance, Malda, Turtle, and Denaria Finance have already integrated the Credible Layer for protocol protection. Public assertions are available at [app.phylax.systems](http://app.phylax.systems).

**Four DeFi protocols now live with Credible Layer protection** Euler Finance, Malda, Turtle, and Denaria Finance have deployed Phylax's Credible Layer to protect their protocols, with more deployments coming soon. **How it works:** - Protocols define "bad outcomes" through assertions - security rules validated by the sequencer - Invalid transactions are dropped before execution - Valid transactions proceed normally - All assertions are publicly viewable at [app.phylax.systems](http://app.phylax.systems) **The shift from bug hunting to outcome prevention** Traditional security focuses on finding bugs, but some always slip through. The Credible Layer takes a different approach by preventing harmful outcomes rather than searching for vulnerabilities. Linea has integrated this technology into its sequencer, stopping exploits before they execute. This risk reduction enables institutions like SharpLink to deploy more capital into DeFi. The technology aims to make DeFi less risky for mainstream adoption.
