Hash = hashlib.sha256(header_bin).digest() #Calculate the first hash Header_bin = code(header_hex, 'hex') #First decode string data to real hex value Splited = for i in range(0, len(str(string)), 2)] Import codecs #library to encode and decode from hex to string and string to hex The 'Get Result' buttonīelow can make that automatically. In the last step change to encoding of the value from Step 4 to Little-Endian the Result should equal the Block hash. Here you can state whether the input is in hex or string. Some hash calculators only consider the input as string instead. Note: When hashing the concatenated inputs, remember to use hex as input format. Here, we take the hex value of step two and apply the SHA-256 twice.

The order is: version || PrevHash || MerkleRoot || Timestamp || Bits || Nonce Now, we concatenate (||) all components into single hex string. Little endian hex means that the least significant byte is on the left side. If leaving them out, we get a wrong result. Note: Some block explorers cut off the seconds in their timestamp. Use for time conversion from local to epoch format. We got the details from the block explorer btc.com. In our example we consider the block 200000 and construct the hash from the information given below. Step 1: Receive Input values and transform them into little endian hexadecimal Double SHA256 and transform to little endian.In order to calculate the block hash we take three steps: So, when taking the values from a block explorer we might have to convert them form decimal to hexadecimal (usually big endian) and subsequently into little endian. The input values need to be in little endian hexadecimal format. With the above parameters a user can verify, if a block is valid.

Nonce: 32-bit number starts with 0 to try hash.

Bits: difficulty of block hash with 32-bits.

Time: Block creation time / current block timestamp and has 32- bits.

MerkleRoot: hash based on all the transaction in the block having 256-bits.

HashPrevBlock: hash of the previous block.

Version: use to create the block, gives a new version once the software is updated.The header of each block comprises the following six parameters used to create the hash of the block: The body is the list of all transaction done by the creator of the block while the header consists of the identification details used to prove the validity of the block and transaction. So I have a transaction.A blockchain is a chain of individual blocks where every block consists of header and body.
