If you’re a developer who wants to stay ahead of the curve and the competition, it’s important to invest in new skills. As blockchain technology continues to evolve, so do the skills needed to stay relevant and competitive in the field. And these skills go far beyond understanding Bitcoin.
7 of the most in-demand blockchain skills in 2023
According to a recent survey, blockchain jobs are expected to grow by more than 50% in the next three years. So, what are the most in-demand blockchain skills for developers in 2023?
1. Coding for Blockchain platforms
One of the most in-demand skills for developers in 2023 is coding for blockchain platforms. This includes coding on platforms such as Ethereum, Hyperledger, IBM Blockchain and EOS.
Developers must be proficient in coding languages such as Solidity, C++ and Java to develop and maintain applications on blockchain platforms. The blockchain bootcamps found at RareSkills can help developers upgrade their blockchain skills.
2. Building DApps
Developers should be familiar with building distributed applications (DApps). DApps are decentralized applications that run on the blockchain. Developers should understand coding languages like JavaScript, Solidity and C++ to build and maintain new DApps.
3. Writing smart contracts
Smart contracts are a type of computer program that is stored on the blockchain and is designed to run automatically when certain conditions are met. These conditions include buying and trading cryptocurrency or creating a legal agreement when someone buys real estate.
Developers must be familiar with programming languages such as Solidity and Vyper in order to write and deploy smart contracts. It is predicted that smart contracts will become commonplace.
4. Cyber security
While the blockchain is considered secure, there is still a need for developers to protect applications on the blockchain. To become a blockchain cybersecurity engineer, developers must understand how to audit systems and be knowledgeable about key security measures.
5. Understand cryptography
Understanding cryptography is also an essential skill for developers in 2023. Cryptography is the science of creating secure communications and transactions within the blockchain. It is able to secure transitions between two nodes in the blockchain network quite quickly.
Developers need to understand the principles of cryptography, such as confidentiality, authentication, integrity, non-repudiation, and key management to succeed here.
6. Interoperability
Interoperability is the ability of computers to exchange and use information. For blockchain technology, this means understanding cross-chain messaging protocols. Multichain translation systems, such as Polkadot, can help developers enable sidechain communication.
7. Database processing
Another important skill for developers in 2023 is database management. Blockchain technology is based on distributed ledger technology, which requires developers to understand database management systems and their software, such as MongoDB, Cassandra and CouchDB.
To be a standout in this field, developers must be able to create and maintain databases. It can be useful to learn non-blockchain databases as a foundation, such as SQL and NoSQL.
