Intro

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
