Layne Haber, Co-founder of Connext Network, discusses the Nomad bridge hack, how it happened, and what can be done to prevent these exploits.    Show highlights: what Nomad is and how it works how the hack occurred and what the vulnerability was how much TVL the protocol had and how much of it was drained why the Nomad hack was unique how this exploit resembled the DAO hack on Ethereum the bounty program that Nomad offered and how hackers responded to it how Nomad is working with law enforcement, and the reasons why law enforcement has decided to get involved how Nomad has partnered with TRM Labs to help with tracking the hackers whether privacy developments in the crypto ecosystem will make it harder for law enforcement to track down hackers why cross-chain hacks happen so often what Layne thinks can be done to improve bridge security what mechanism can be implemented to prevent errors that enable these types of mass looting what Layne expects to see in the next few weeks around the Nomad exploit   Thank you to our sponsors!   Crypto.com: https://crypto.onelink.me/J9Lg/unconfirmedcardearnfeb2021 Ava Labs: https://www.avax.network/ Oasis: https://oasisl.ink/3Bo612R EPISODE LINKS   Layne Twitter: https://twitter.com/LayneHaber Nomad Hack:  https://www.theblock.co/post/160731/nomad-cross-chain-crypto-bridge-suffers-possible-exploit Sam Sun explaining the hack: https://twitter.com/samczsun/status/1554252024723546112?s=20&t=SHIZQRqJ00mmuZVXFKXuZg Nomad’s bounty program: https://twitter.com/nomadxyz_/status/1555293965049630722?s=20&t=RxH5UuWbBXiRLqu5gHDNyg Pranay Mohan’s thread: https://twitter.com/pranaymohan/status/1556402131325915137?s=20&t=RxH5UuWbBXiRLqu5gHDNyg $36 million recovered: https://twitter.com/nomadxyz_/status/1556681397993058304?s=20&t=makkX3SX1ezAXQSd6fdZYA    Cross-chain security:  Chainalysis article: https://blog.chainalysis.com/reports/cross-chain-bridge-hacks-2022/ Adam Cochran on crypto bridges: https://twitter.com/adamscochran/status/1554473323073093634?s=20&t=8YFw6sPEGfjvh12q8w7p-Q Vitalik’s take on cross-chain applications: https://old.reddit.com/r/ethereum/comments/rwojtk/ama_we_are_the_efs_research_team_pt_7_07_january/hrngyk8/ Previous Unchained coverage: The Chopping Block: How to Improve DeFi and Cross-Chain Bridge Security: https://unchainedpodcast.com/bridge-hacks-have-caused-1-billion-in-losses-heres-why-bridge-security-is-tricky/ Bridge Hacks Have Caused ~$1 Billion in Losses.
