A Java program that implements a MerkleTree to be used in a blockchain.

What I Learned

In this project, I learned about:

• Blockchain technology and how it works
• Merkle Trees and their use in Blockchain
• Implementing algorithms and methods in Java, including:
  • Building a Merkle Tree from transactions
  • Adding a block to a Blockchain
  • Solving the Proof-of-Work puzzle
  • Validating the integrity of a Blockchain if a block is corrupted
