DApp Courses

DApp stands for decentralized application. A decentralized application is a software application built to run on a decentralized peer-to-peer network. Its principal area of use is in the Ethereum blockchain network for running smart contracts. The smart contract is likely coded in an Ethereum-specific programming language, like Serpent, Solidity, or Vyper. But the front end of a DApp can be written in any language on any framework. As a transparent, open-source application, no single entity has complete control over its use. There are three main types of DApps: managing money, money is involved but includes information from other sources, and an “other” category that provides for governance systems and voting.

Since a DApp is deployed on a P2P decentralized network, malicious parties cannot target a DoS attack toward an individual application. This benefit results in zero downtime. Because no single user can block interaction with the blockchain, DApps are resistant to any censorship. Data on the blockchain is indisputable and immutable, so forgery and misrepresentation are nearly impossible. Additionally, users who deploy a DApp can maintain their privacy, not needing to disclose personal information. Because smart contracts can be analyzed and verified without needing to trust a central authority, there is no risk that financial data and records can be tampered with or manipulated. DApps also operate using tokens generated by cryptographic algorithms. This is an additional layer of security that minimizes any vulnerability to malicious attacks or transactions.

The first thing you’ll need to learn is basic coding. Since DApps can be built in any language on any framework, you can choose which coding languages to learn. Java and C# seem to be good choices suggested in the industry. Next, you’ll need to learn Ethereum, including knowledge of blockchains and the coding and deploying of smart contracts. Learn an Ethereum-specific coding language such as Solidity. Solidity was inspired by C++, Java, JavaScript, and Python, so if you have any background in those coding languages, it will probably help. Additionally, open-source frameworks like VueJS and React can be used for building DApp user interfaces and components. Udemy offers a variety of online courses to equip you with the skills you need to become a DApp developer.
