 ### submitblock

 ### getlastblockheader
 
+Block header information for the most recent block is easily retrieved with this method. No inputs are needed.
+
+Outputs:
+
+* *block_header* - A structure containing block header information.
+  * *depth* -  The number of blocks succeeding this block on the blockchain. A larger number means an older block.
+  * *difficulty* - The strength of the Monero network based on mining power.
+  * *hash* - The hash of this block.
+  * *height* - The number of blocks preceding this block on the blockchain.
+  * *major_version* - The major version of the monero protocol at this block height.
+  * *minor_version* - The minor version of the monero protocol at this block height.
+  * *nonce* - a cryptographic random one-time number used in mining a Monero block.
+  * *orphan_status* - Usually `false`. If `true`, this block is not part of the longest chain.
+  * *prev_hash* - The hash of the block immediately preceding this block in the chain.
+  * *reward* - The amount of new atomic units generated in this block and rewarded to the miner. Note: 1 XMR = 1e12 atomic units.
+  * *timestamp* - The time the block was recorded into the blockchain.
+
+In this example, the most recent block (990793 at the time) is returned:

 ### getblockheaderbyhash
 
+Block header information can be retrieved using either a block's hash or height. This method includes a block's hash as an input parameter to retrieve basic information about the block.
+
+Inputs:
+
+* *hash* - The block's sha256 hash.
+
+Outputs:
+
+* *block_header* - A structure containing block header information.
+  * *depth* -  The number of blocks succeeding this block on the blockchain. A larger number means an older block.
+  * *difficulty* - The strength of the Monero network based on mining power.
+  * *hash* - The hash of this block.
+  * *height* - The number of blocks preceding this block on the blockchain.
+  * *major_version* - The major version of the monero protocol at this block height.
+  * *minor_version* - The minor version of the monero protocol at this block height.
+  * *nonce* - a cryptographic random one-time number used in mining a Monero block.
+  * *orphan_status* - Usually `false`. If `true`, this block is not part of the longest chain.
+  * *prev_hash* - The hash of the block immediately preceding this block in the chain.
+  * *reward* - The amount of new atomic units generated in this block and rewarded to the miner. Note: 1 XMR = 1e12 atomic units.
+  * *timestamp* - The time the block was recorded into the blockchain.
+
+In this example, block 912345 is looked up by its hash:
+
+{:.cli-code}
+<span style="color: cyan;">[ monero->~ ]$</span> curl -X POST http://127.0.0.1:18081/json_rpc -d '{"jsonrpc":"2.0","id":"0","method":"getblockheaderbyhash","params":{"hash":"e22cf75f39ae720e8b71b3d120a5ac03f0db50bba6379e2850975b4859190bc6"}}' -H 'Content-Type: application/json'

+    },
+    "status": "OK"
+  }
+}
+
+
 ### getblockheaderbyheight
 
+Similar to `getblockheaderbyhash` above, this method includes a block's height as an input parameter to retrieve basic information about the block.
+
+Inputs:
+
+* *height* - The block's height.
+
+Outputs:
+
+* *block_header* - A structure containing block header information.
+  * *depth* -  The number of blocks succeeding this block on the blockchain. A larger number means an older block.
+  * *difficulty* - The strength of the Monero network based on mining power.
+  * *hash* - The hash of this block.
+  * *height* - The number of blocks preceding this block on the blockchain.
+  * *major_version* - The major version of the monero protocol at this block height.
+  * *minor_version* - The minor version of the monero protocol at this block height.
+  * *nonce* - a cryptographic random one-time number used in mining a Monero block.
+  * *orphan_status* - Usually `false`. If `true`, this block is not part of the longest chain.
+  * *prev_hash* - The hash of the block immediately preceding this block in the chain.
+  * *reward* - The amount of new atomic units generated in this block and rewarded to the miner. Note: 1 XMR = 1e12 atomic units.
+  * *timestamp* - The time the block was recorded into the blockchain.
+
+In this example, block 912345 is looked up by its height (notice that the returned information is the save as in the previous example):

+{:.cli-code}
