Blockchain Defined

A block refers to the cryptographic technology based mathematical problem that is to be solved by the computerBlockchain in order to complete the block. The block allows the users to modify information inside of it, which in return invalidates the data. In order to fix it, the incorrect draw has to be replaced with the correct one. 

The creation of a new block creates a link of data from the previous block, thus the name blockchain. As the data gets older, it becomes more secured. Generally speaking, a block is valid when there are sufficient blocks added to the chain to make it more secured. Taking cryptocurrency into account, blockchain serves as the storage of immutable transaction ledger for the currency that is traded. 

Blockchain Broken Down 

The recent transactions in the blockchain are recorded in the block. Once the transaction is complete, the block becomes a permanent database and it directly goes into the blockchain. For every completed block, a new blockchain is created. The countless blocks in the blockchain are interconnected with one another in a linear and chronological manner. Each previous block leaves a mark on every newly generated block. The address of every user and all their balances is contained in the blockchain. 

Transactions are immutable through blockchain. This means that no matter what happens, the transaction details will remain in the blockchain. It makes use of cryptography to ensure the data can be distributed, but can’t be copied. Thus, the size of blockchain is an ever growing issue. 

Blockchains on Bitcoin 

Bitcoin is the first ever cryptocurrency to introduce the blockchain technology. Bitcoin is a decentralized, digital and leading cryptocurrency. This means that users are in full control of every transaction in their account and a third party isn’t needed at all. Every completed transaction is recorded in both blocks and blockchain wherein these transactions are recorded publicly. A publicly recorded transaction means that the transaction is verified and is released on to other Bitcoin users. Through mining, a new block is added to the blockchain. 

With Bitcoin, all nodes in the system share the same blockchain database. Once a new network joins the system, every computer that is connected to the network receives every single detail or information of the blockchain. 

How It Works 

  1. Each trade is recorded. The recorded lists include all the detail and a digital signature of both parties. 
  2. The records are verified whether they are valid or not.
  3. Once the record is verified, these records will be added to the block which contains a hash. A hash is a unique code and is contained by the previous transaction as well
  4. The block is successfully added to the blockchain. The blocks are connected in a specific order through the hash.


  1. Cheaper electronic ledger maintenance 
  2. Fewer errors and no repetitive confirmation steps in DLT systems
  3. Processing days are lesser


With the endless opportunities of a decentralized system, the blockchain technology is an addition which brings the creation of businesses and operations to the next level by making the process flexible and secured. The blockchain is surely a must watch innovation especially for investors as the demand of it continue to rise throughout the passing years in as much as it’s development is amazing. The use of blockchain seems endless and surely, more and more products and services will be developed out of it.
