What is Blockchain Technology

Satoshi Nakamoto developed the peer to peer cash system protocols. This protocol become the foundation of blockchain which is also known as distributed ledgers. Blockchain works like ledger or a global spreadsheet. It runs over the network means computers provided around the world, it does not have any central database where data gets stored. Data is publically available as it is run over network not run by single organisation.

Blockchain uses public and private key to maintain virtual security. Nowadays we transfer money from one person to another person securely, this transaction is possible using blockchain technology. Person don’t need to go to bank to transfer money to another person account.

Many financial industries uses blockchain technology to provide secure transactions. Blockchain is very vast technology, not only financial industry uses it but also it is helpful in other industry as well.

Blockchain Bitcoin Technology

Cryptocurrency/Bitcoin is a part of blockchain and the network which required to power it. A blockchain is a shared database that stores data known as distributed . Encryption methods are used to secure the data within the blockchain.

Whenever transaction happens on blockchain, information copied from one block to another with new encrypted data. Each transactions present over the network are validated by validators (miners). After verifying each transactions, new block is opened and bitcoin gets created. This Bitcoin is given to the miners (who verified the encrypted data) as rewards. Miners are free to use it, Sell it or hold it.

SHA-256 hashing algorithm use by Bitcoin to encrypt the data which is store in the blocks on the blockchain. Stored data encrypted into 256 bit hexadecimal number. The number contain all the transaction data as well as other information.


Blockchain is nothing but data linked between the blocks. Within the network all the transactions are placed in the queue (one after another) to be validated by validators (miners). All the miners present over the Bitcoin blockchain network try to verify same transaction parallelly. Miners use mining software and hardware to solve this nonce. All miners try to solve four byte number that is present in block header.

Miners keep on regenerating the block headers repeatedly until it matches the target number specified by blockchain. Once the block header solved, new block is created in order to verify and encrypt more transactions.

How to mine Bitcoin?

It is difficult to solve the hash because we are competing with network of miners and per second it generates 220 quintillion hashes.

Application Specific Integrated Circuits (ASICs) is the machine that is specifically build to mine bitcoins and it has capacity to generate 255 trillion hashes per second. Whereas computer with newest/latest technology hardware can generate only 100 million hashes per second.
