🆕 Testnet Restart Approaching has been tracking our testnet since its genesis! 🔹Simple Recap

This version is the most important release yet, as it will serve as the multiclient testnet target. That is, clients will interop with each other starting from this upcoming testnet restart. This restart is also the prime release of novel features in our beacon chain that will offer significant reduction in resources used by the nodes, including a critical improvement to network bandwidth usage. Among the changes included are:

Revamped state management:

Instead of saving the beacon state every slot to the database, we only persist states after a certain interval, reducing load significantly when it comes to disk writes and risk reads. Upon reading a historical state, we can replay blocks on top of the closest persisted state and recreate whatever is requested quite eff...
