gm, readers. At Automata we work on protecting privacy and fairness. And in this newsletter, we find more reasons to talk about it. Explore headlines and catch up on the biggest crypto news in Web3 privacy.

All requests to Leo are routed through an anonymous server, and cannot be traced back to a particular IP. No login information is required to use the chatbot, and conversations are not recorded or used to train AI models. This week, blockchain security audit firm ChainLight reported a vulnerability in the zkSync Era mainnet, that if exploited, would have exposed $1.9 billion to risk. The soundness bug would have allowed a malicious party to produce otherwise incorrect proofs that the L1 verifier contract would accept as valid. ChainLight @ChainLight_io Exploiting ZK-EVM. After discovering a @zkSync Era bug on September 15th, we intentionally produced a false "proof" to battle-test our findings. Spending 100 GPU hours on A100s to generate the exploit, we turned a ZK soundness bug into a full token-stealing exploit. As this 200 11:00 AM • Nov 3, 2023 Nym is set to launch a decentralized VPN, NymVPN, that routes web traffic through two decentralized nodes. This “two-hop” structure encrypts and directs user traffic to one server (the first hop), then to a second server (the second hop), and finally to its destination on the internet. This adds an extra layer of privacy by making it challenging for malicious attacks to track both the source and destination of user traffic, in contrast to conventional VPNs that rely on a single central server.
