Primary Skills

The skills listed below are essential for becoming a proficient Blockchain Developer and excelling in the role

Blockchain Fundamentals

 

These are the foundational concepts of blockchain technology that help create decentralized applications, maintain nodes, and implement network contracts. Using these fundamentals, developers build various blockchain applications.

Smart Contracts

 

These are self-automated, code-based agreements that enable a blockchain developer to enforce the terms of a contract to conduct automated transactions and secure smart contract code from the beginning to minimize the need for post-development auditing.

Decentralized Applications (DApps)

 

These Software applications run on blockchain networks. It utilizes the decentralized nature of blockchain to enhance transparency, security, and trust. Blockchain developers leverage this build DApps to benefit various industries.

Blockchain Platforms

 

Having a good understanding of Blockchain platforms helps developers create and manage blockchain networks, such as Ethereum or Hyperledger.

Token Standards

 

These are the defined rules and protocols that help create, manage, and interact within a blockchain ecosystem. Blockchain developers are required to have a sound understanding of how to use these tokens to differentiate between fungible and non-fungible tokens.

Blockchain Security

 

It helps Blockchain developers protect blockchain networks from attacks, vulnerabilities, and unauthorized access.

Wallet Integration

 

It is the process of incorporating digital wallets into applications for secure storage and management of cryptocurrency.

Consensus Mechanisms

 

It comprises protocols like Delegated Proof of Stake (DPoS), Byzantine Fault Tolerance (BFT), Proof of Work (PoW) or Proof of Stake (PoS). By leveraging them, Blockchain developers ensure agreement among network participants in blockchain transactions.

Blockchain Development Tools

 

It comprises software and SDKs that help a Blockchain developer build, test, and deploy blockchain applications. These tools streamline the development process and provide resources for working with blockchain technologies.

Interoperability

 

It is the ability of different blockchains to communicate and exchange data. As a result, seamless interaction between blockchain networks is established. Blockchain developers facilitate it to implement cross-chain standards, create bridges, and utilize oracles for data exchange.

Secondary Skills

  • Cryptography

    It is the practice of encoding information to protect it from unauthorized access, ensuring confidentiality, integrity, and authentication. It allows blockchain developers to identify vulnerabilities related to encryption and suggest recommendations to enhance overall security.

  • IPFS (InterPlanetary File System)

    This decentralized, peer-to-peer file storage service helps Blockchain developers make data retrieval efficient and censorship-resistant. 

  • Web3.js or ethers.js

    These libraries are used for interacting with blockchain networks. Therefore, developers can build decentralized applications (DApps) and interact with smart contracts.

  • Privacy and Confidentiality

    This feature of blockchain ensures data privacy and confidentiality, which is crucial for sensitive transactions and enterprise adoption.

  • idechains and Plasma

    Sidechains and plasma are solutions to enhance the scalability and efficiency of blockchain networks. Developers are required to know which solution to choose based on the specific requirements.

  • Smart Contract Security Auditing

    It is a process of reviewing and assessing smart contracts' code for vulnerabilities. By doing so, blockchain developers can prevent potential exploits and ensure the security of blockchain applications.
