# GetBlockDetailsByBlockHashRibs
## Properties
**difficulty** | **String** | Represents a mathematical value of how hard it is to find a valid hash for this block. |
**bits** | **String** | Represents a specific sub-unit of Zcash. Bits have two-decimal precision |
**chainwork** | **String** | Represents a hexadecimal number of all the hashes necessary to produce the current chain. E.g., when converting 0000000000000000000000000000000000000000000086859f7a841475b236fd to a decimal you get 635262017308958427068157 hashes, or 635262 exahashes. |
**merkle_root** | **String** | Defines the single and final (root) node of a Merkle tree. It is the combined hash of all transactions' hashes that are part of a blockchain block. |
**nonce** | **String** | Represents a random value that can be adjusted to satisfy the Proof of Work. |
**size** | **i32** | Represents the total size of the block in Bytes. |
**stripped_size** | **i32** | Defines the numeric representation of the block size excluding the witness data. |
**version** | **i32** | Represents the block version number. |
**version_hex** | **String** | Is the hexadecimal string representation of the block's version. |
**weight** | **i32** | Represents a measurement to compare the size of different transactions to each other in proportion to the block size limit. |
**extra_data** | **String** | Represents any data that can be included by the miner in the block. |
**gas_limit** | **i32** | Numeric representation of the block gas_limit |
**gas_used** | **i32** | Numeric representation of the block gas_limit |
**mined_in_seconds** | **i32** | Specifies the amount of time required for the block to be mined in seconds. |
**sha3_uncles** | **String** | Defines the combined hash of all uncles for a given paren |
**total_difficulty** | **String** | Defines the total difficulty of the chain until this block, i.e. how difficult it is for a specific miner to mine a new block. |
**uncles** | **Vec<String>** | |
**ds_block** | **i32** | Numeric representation of the ds block |
**ds_difficulty** | **String** | Numeric representation of the ds difficulty |
**ds_leader** | **String** | String representation of the ds leader |
**micro_blocks** | **Vec<String>** | |
