The Need for Interoperability Grows

As we see the pull towards the Ethereum ecosystem increases, the need for interoperability between chains is more prevalent than ever. In our zk-bridge report, we highlighted a few projects working on developing a bridging solution aimed at proving the consensus of a source chain on the target chain’s execution layer in a reliable and scalable manner. Upon verification, access to the block header is granted, which enables the proving of anything on the state of the source chain in the context of the target chain, such as messages and token transfers. Here we illustrated a few major protocols that have similar approaches to bridge design but differ in which consensus protocols they support as well as their proving mechanisms.
