Each block is connected with all other blocks before and after it through a distinctive hash pointer which adds more security to … Read more

What is the difference between Proof-of-work and Proof-of-stake?

The main differences between the Proof of Work and Proof of Stake are: Proof of Work Proof of Work(PoW) algorithm is used to confirm the transaction and creates a new block to the chain. In this algorithm, miners compete against each other to complete the transaction on the network. The process of competing against each … Read more

What is encryption? What is its role in Blockchain?

We know that the security of data is always matters. Encryption is a process of converting information or data into a code to prevent unauthorized access. It helps organizations to keep their data secure(i.e., prevent unauthorized access). In this technique, the data is encoded or changed into an unreadable format up to some extent before … Read more

What is a 51% attack?

The 51% attack on a blockchain network refers to a miner or a group of miners who are trying to control more than 50% of a network’s mining power, computing power or hash rate. In this attack, the attacker can block new transactions from taking place or being confirmed. They are also able to reverse … Read more

What are the limitations of blockchain?
