# Understanding rdPoS 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. --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question. Perform an HTTP GET request on the current page URL with the `ask` query parameter: ``` GET https://docs.applayer.com/testnet/understanding-rdpos.md?ask= ``` The question should be specific, self-contained, and written in natural language. The response will contain a direct answer to the question and relevant excerpts and sources from the documentation. Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
