Understanding rdPoS

How AppLayer uses Random Deterministic Proof of Stake.

To keep consensus on such a blazing fast network without tripping up and/or having to deal with rollbacks, AppLayer uses a random deterministic block creation that allows only one given node to create a block for a given time, eliminating the risk of a block race condition in the network.

This is implemented in AppLayer as its own consensus algorithm, called rdPoS (Random Deterministic Proof of Stake), which empowers Validators and Sentinels to deal with block congestion and random number generation. This chapter aims to explain in-depth the rdPoS algorithm used by the AppLayer protocol, from concept to implementation.
