In this week’s episode, Anna chats with Vaibhav Chellani, a bridge builder and the co-founder of Socket. They explore what makes up the components of a bridge, the types of bridges, and then look at their framework for analysing the security trade-offs of different bridge architectures. This is an important topic, since at present, there are more and more bridges coming online to connect all the different chains together. And with these come a number of new bugs, hacks and exploits. This episode gives us an overview on how to think about bridges.
