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
Smart contracts caught attention post Ethereum release. Businesses across the world are now keen to integrate smart contracts into their systems to benefit from the application of business logic. Hence, developers striving to get into the blockchain field should learn about smart contract development. For this, you need to get a good grasp on languages such as Chaincode, Viper, and Solidity.
Another important skill to master as a blockchain developer, web-development involves the development of front and as well as back end functions including building interactive graphic interfaces. Blockchain developer should also be able to handle API and requests.
Let’s now have a closer look at the types of blockchain developers.
To understand what responsibilities do a blockchain developer handle, you need to know the various functions associated with it. Contrary to what you believe, the career possibilities of a blockchain developer are not only about building blockchains. There are multiple job layers.
Common job roles of a backend developer are:
• Designing and developing Application Programming Interface (API) to integrate blockchains.
• Designing software and handling everything from testing to deployment and render technical support.
Blockchain Project Managers
Project managers are responsible for blockchain-specific, yet wider job roles. They need to handle a wide spectrum of responsibilities ranging from:
• Developing decentralized applications and maintaining them.
• Blockchain project supervision
• Advising on ICO structure
• Understanding the requirements and designing apps that could cater to their business requirements.
• Training of team members if required.
To become a smart-contract engineer, you need to know languages such as Solidity, Go and Python.
• Developing smart contracts and regular auditing to find loopholes
• Ensure security
• Conduct business process testing
Blockchain course helps you learn the basics of blockchain and cryptography. Training helps you decide which aspect of the technology you wish to focus on. There are a variety of courses emphasizing on various aspects of blockchain development.
To decide on which blockchain course to enrol, you need to decide on your career goal, what would you like to specialize in. Having clarity on your job expectations help you zero down on the best course.
