The eth_getUncleCountByBlockHash method returns the number of uncles in a block from a block matching the given block hash. This lightweight method allows you to quickly check how many uncle blocks are referenced in a specific block without fetching the complete block data.

This method is useful for blockchain statistics, mining analysis, network health monitoring, and historical research. A high uncle count indicates network propagation issues or high mining competition. Note that uncle blocks are an Ethereum Proof of Work concept and do not apply to Tron's consensus mechanism, so this will always return 0x0 on the Tron network. This method is included for API compatibility.
