Ethereum Infrastructure: Geth Implements REST-SSZ for Engine API
The architectural divide between the execution and consensus layers of the Ethereum network relies on a specialized communication interface known as the Engine API. Recently, developers working on Go Ethereum, the most widely used execution client, introduced a significant update to this bridge. By transitioning the Engine API from a text based JSON RPC protocol to a REST based architecture using Simple Serialize or SSZ, the implementation aims to reduce overhead and improve the efficiency of data exchange across the stack.
