All

Retrieves all the uncles within the specified range.

📘

When two miners solve a block at roughly the same time, the network can only include one of them in the blockchain, while the other one is considered an "uncle."

In a PoS (Proof of Stake) network, block validation is done by validators who are chosen to validate blocks based on the amount of stake they hold, rather than by miners who must compete to solve complex computational problems. As a result, there is typically no concept of an "uncle" block in a PoS network, but historical uncle data pre-Ethereum Merge would still be available with this endpoint.
