What is blockchain?

Blockchain is a digital ledger that records transactions across multiple information systems. Everyone can access it, but its structure prevents unauthorized modifications or fraudulent entries. Each entry is a tamper-proof record or "block" of information connected to the previous transaction by a complex string of numbers called a cryptographic hash.

Knowing how to work with blockchain can open up a variety of positions for you in the security and contracts industries. As more industries adopt blockchain to verify products and agreements, blockchain skills may translate to more job opportunities.

Why learn blockchain?

  • Develop in-demand technical knowledge by learning how blockchain supports secure, transparent, and decentralized digital transactions across industries.
  • Explore career opportunities in areas like software development, financial technology, cybersecurity, supply chain management, and digital asset innovation.
  • Gain practical skills to evaluate, implement, or work with emerging blockchain solutions that can improve efficiency, trust, and data integrity.

Data scientist

Data scientists analyze large amounts of data to uncover insights for organizations. Increasingly, much of that information lies on the blockchain. It allows data scientists to work with verified and reliable data. Many industries are now hiring in-house data scientist teams, but other opportunities also exist in government, research, and academia.

  • Required education: Bachelor's degree in computer science, mathematics, business, statistics, or a related field; some employers may require a master's degree.
  • Median annual salary (May 2024): $112,590

Frequently asked questions

Will AI replace blockchain?

No, experts do not expect AI to replace blockchain because the two technologies serve two different purposes. AI focuses on analyzing data and automating decision-making. Conversely, blockchain provides secure, decentralized recordkeeping. Many organizations are now exploring how to use AI and blockchain together.

Is blockchain still worth learning?

Yes, blockchain is still worth learning when you are interested in working in emerging technologies and digital innovation. Blockchain continues to be used in financial services, supply chain management, and identity verification. This makes it a valuable skill set for understanding and contributing to evolving technology ecosystems.

How does blockchain technology work?

Blockchain technology works through cryptographic hashing, a method of encrypting information. It involves inputting information into an algorithm and "hashing" it into a fixed-length, anonymized output.

When you cryptographically hash an input, the output is identifiable as having gone through that specific algorithm, but doesn't include any information about the transaction. It's statistically unlikely that anyone can decode the information after it has been hashed.

In blockchain technology, cryptographically hashed information is stored in a database. This database is saved to many computers, but all must match to verify an entry, a process that ensures the validity of blockchain transactions.

How long does it take to learn blockchain?

Understanding the basics of blockchain can take as little as a few weeks. Becoming a blockchain developer may take longer, however, depending on your familiarity with programming and complex algorithms.

How hard is it to learn blockchain?

The difficulty of learning blockchain depends on your goals and previous experience with the subject. If you want to learn the basics of blockchain to make informed decisions in your workplace, it may take just a few weeks or a single course to gain the knowledge you need. However, if you want to actively work with and develop blockchain, it may take longer.
