20 Online Courses for All Levels to Learn Blockchain Programming
In this article, you can find online Blockchain programming courses for all levels.
A blockchain is a growing list of records, called blocks, that are linked together using cryptography. Each block contains a cryptographic hash of the previous block, a timestamp, and transaction data (generally represented as a Merkle tree). The timestamp proves that the transaction data existed when the block was published in order to get into its hash. As blocks each contain information about the block previous to it, they form a chain, with each additional block reinforcing the ones before it. Therefore, blockchains are resistant to modification of their data because once recorded, the data in any given block cannot be altered retroactively without altering all subsequent blocks.
Blockchains are typically managed by a peer-to-peer network for use as a publicly distributed ledger, where nodes collectively adhere to a protocol to communicate and validate new blocks. Although blockchain records are not unalterable as forks are possible, blockchains may be considered secure by design and exemplify a distributed computing system with high Byzantine fault tolerance.
Below we have prepared 20 online blockchain programming courses for all levels.

Ethereum Tutorial: Ethereum & Smart Contracts from Scratch
David Joseph Katz via Udemy
A smart contract blockchain can support decentralized applications. This opens the door to a wide variety of solutions. Based on these points and more it would definitely be a valuable learning experience to try building a smart contract blockchain and cryptocurrency like Ethereum. So it can be quite surprising to discover that existing tutorials are challenging to find. Sure, there’s the Ethereum documentation. But this information is better understood when you’re pretty knowledgeable about blockchains already. Likewise, other resources you find, like articles and videos, mostly focus on aspects of a completed Ethereum system. They don’t take you through the process of completely building a smart contract blockchain and cryptocurrency. However, it’s understandable.
