What is hash ?

What is hash

“A function that converts an input of arbitrary length into an encrypted output of a fixed length is called a hash.”

  • It is essential to blockchain management in cryptocurrency.

Hash in techpay Blockchain

Techpay is a decentralized, distributed, public digital ledger that records all the transactions. 

The validation process for Techpay blockchain transactions relies on data being encrypted using algorithmic hashing.

During the process of mining, a hash has the following used :

  •  A function that meets the encrypted demands needed to solve for a Techpay blockchain computation.
  • Hashes are of a fixed length since it makes it nearly impossible to guess the length of the hash if someone was trying to crack the blockchain.
  • The same data will always produce the same hashed value.
  • A hash, like a nonce or a solution, is the backbone of the Techpay blockchain network.
  • It is developed based on the information present in the block header. 

 Meet certain requirements,

Techpay miners need a certain nonce to calculate hash in multiple attempts ( start with zero). Miniers find the right nonce then add to the participant Block in the Techpay Blockchain. 

Identification of blocks in the Blockchain by the following :

  • Through header 
  • Depending on Merkel root and timestamp
  • Block hash that is predetermined
  • Nonce

Techpay offers a unique feature of storing data as a hash value in the current block, which makes it an immutable block without changing all the blocks.

nonce refers to a number or value that can only be used once. 

Hash function and Protocol are used by a nonce

In the context of Techpay blockchain technology, the number of times per second that computers on the Techpay network are hashing data to verify transactions and perform the encryption that secures the network.

To calculate block hash, Techpay needs to know the nonce in many attempts that meet certain requirements of business 

When businesses add new transactions to the Block, they first find the nonce that ensures the right to add the next block in techpay Blockchain. Then verify it 

During this process of verification, the following process will follow:

  • To cover all the data of block, minor ensure to complete the work
  • Find the difference between the hash value of the current block and the target 

 Participants when accepting the creation of the block, when miners first ensure the proof of work 

10 minutes per block is required to erase the difficulty of adding the block to the Techpay Blockchain.

A random whole number which is 32-bit can be used in the block for  hashing the value which are adjusted by miners

A nonce is a number that is used only once and is essential for  Proof of Work in which calculation of hash value requires computer resources and gives a chance to add value to the Blockchain.

In Techpay Blockchain, a nonce is a number that can be used only once. When the perfect nonce is found, it is added to the hashed value in the block with the number that rehashed the block value.

Also in techpay, once golden nonce is found, miners test and discard other millions of nonce per second for the fastest verification than others. After that, they complete the block and add it to the Blockchain.

How Hashes Work

Typical hash functions take inputs of variable lengths to return outputs of a fixed length. 

“A cryptographic hash function combines the message-passing capabilities of hash functions with security properties.”

In all processes of mining, many different nonce values performing a hash function used different miners until they produced valid output. But in some cases output is not valid, different nonce values are tried by miners to produce valid output . Once the output is valid, a new block is successfully mined at the end of the proceeds.

In cryptography, a nonce is a :


  • Hashing 
  • Identification
  • Electron 
  • Signature

With Techpay, a nonce is an arbitrary number that miners used to repeat the output with their hash calculations. Miners used a new nonce value in every trial to insure the possibility of the nonce is close to zero.

 For generated new blocks, the average number of hash blocks is adjusted every 10 minutes. This process is called difficult adjustment.

Hash rate is related to the mining of a new block committed to the Blockchain system.

Higher the threshold depends on increasing the hashing power network.

Less hashing power is needed when miners decide to stop mining. In this process, the protocol will ensure that block generation follows a 10-minute schedule to adjust the difficulty.

It is the process in which Techpay transactions are:

  • Gather
  • Verified
  • Record into a  digitally Techpay Blockchain 
  • Essential to maintaining the unity of the network 
  • Miners is responsible to introduce new coins into the system

In the case of Techpay, centralized authority is not responsible for the insurance of new coins.

New introduction of cryptocurrency is based on the process of mining.

Which follow :

  • Set protocol
  • Rules that are predefined 
  • Primary rules

Consensus algorithms are the primary rules which define who rules can be followed. It is essential for the verification of transactions.

In Techpay, participants that are involved in the process of mining play a key role in the security of the network.

Firstly, miners is responsible to gather:

  • Transactions that are unconfirmed from the memory pool
  • Fulfill arbitrary condition
  • Organize all of them in a candidate block
  • Obtain desired difficulty 
  • Try to verify
  • Special maker to prevent illegal reproduction of file 

Transactions are sent to participants’ blocks ( coin base ) and then recorded in the block. 

After the formation of unconfirmed transactions:

  • The result is organized into pair 
  • Then hashed
  • The new output is produced
  • Then pair has organized the output
  • Then hashed again
  • Repeat the process
  • Try to produce a single hash
  • Along nonce, then combine with confirmed block
  • Lastly, producing a hash block for participants. 

For the success of miners, different nonces need to perform various hashing functions based on trial and error to perform expected results. If miners facilitate the candidate hash block.

  • produce miner function 
  • Act as identifier
  •  Average ten minutes is required to complete the whole process. 
  • Techpay protocol is used to identify block rewards.
