Blockchain is a growing chain of cryptographically linked blocks or records that are resistant to modification. It records every transaction and thus, it is an open, transparent ledger of transactions between two parties. The sequential list of all the transactions is permanent, with each block linked to the previous block with a hash, timestamp, and details of the transaction. This feature makes blockchain highly resistant to manipulation and attack. This explains why cryptocurrencies like bitcoin use blockchain to record transactions.

How Is Cryptography, Blockchain And Hyperledger Technologies Related?

Simply explained, cryptography is securing a private message to ensure its confidentiality. Only the intended person can read a cryptographically secured data. As a third party won’t be able to find the keys to decode the message, no one other than the intended people would be able to understand the encrypted message. It involves encrypting and decrypting content using various methods and encryption keys.

How to Become a Blockchain Developer?

The primary responsibility of a blockchain develops optimizes blockchain protocols, and to develop build smart contracts. To become a blockchain developer, you need to enrol in a blockchain course.

This is because you need to be adept at certain technical skills to become a blockchain developer. One needs to master certain concepts like cryptographic hash and distributed ledger etc. self-learning could be tedious, so it is always better to take up some blockchain courses to give a boost to the learning process. co

To master the blockchain development process, you should have a good grasp of data structures. Many blockchain developers explore tweaking data structures and combine them with cryptography to develop fool-proof and secure systems. Most popular data structures are Petrecia and Merkle trees. Data structure and blockchain are two inseparable concepts, and learning blockchain, beyond any doubt, is incomplete without having learned data structure.

You might have already understood the importance of cryptography in blockchain development. Cryptographic methods are used to develop digital signatures. It is also used to develop crypto contracts or smart contracts, which is a computer contract that involves and controls cryptocurrency transactions under certain controls. Smart contracts became popular post Ethereum release. Most of the businesses

Smart Contract Development
