Earning Digital Leader Academy’s Blockchain Fundamentals validates a foundational understanding of blockchain technology.
Who should take this exam?
Digital Leader Academy Certified Blockchain Fundamentals is intended for anyone with basic knowledge of blockchain. Before taking this exam, we recommend you have the following:
- Two months of exposure to blockchain
- Basic understanding of encryption, consensus mechanisms, and smart contracts
Exam Content
A deep dive into why money has value and if cryptocurrency is money, looking specifically at Bitcoin
- Articulate what a cryptocurrency is
- Describe the differences between Bitcoin and Ethereum
Cryptography is the art of writing or solving codes, and is used in cryptocurrencies to make them difficult to counterfeit.
- Decode a Cipher
- Explain the concept cryptography and cipher?
- Create and use your own cipher
Symmetric encryption encodes a message using a key that the message can’t be read without. Asymmetric encryption uses two keys, a public key and a private key, to encrypt data.
- Differentiate between symmetric and asymmetric encryption
- Argue why do we need encryption
- Analyze the problems with symmetric encryption
- Explain the concept of public & private Keys
Hashing is a more complicated form of asymmetric encryption where the encrypted message will always be 43 characters (256 bits) long. This is the type of encryption that blockchain uses to encrypt everything.
- Argue whether or not regular encryption is enough?
- Explain why is hashing so useful?
- Create a digital signature
- Complete a hashing escape room
Blockchain systems are made of blocks, which hold data and hashes, chained together.
- Define the term blockchain
- Explain the terms “distributed, decentralized, and digital ledger”
- Illustrate how transactions in a blockchain operate
- Detail the components of a block
Consensus mechanisms are methods for making decisions when there is no single person or central authority in charge. This lesson introduces students to the two most popular consensus mechanisms: proof of work and proof of stake.
- Demonstrate how blockchain embeds trust into its system?
- Explain the concept of consensus, proof of work, proof of stake, and mining
Non-Fungible Tokens (NFTs) are unique cryptographic tokens that exist on a blockchain and cannot be replicated.
- Clarify how NFTs and cryptocurrencies are related
- Describe what an NFT is
- Identify use cases for NFTs
Smart Contracts are a program stored on a blockchain that executes automatically when the agreed-upon conditions are met.
- Traditional Contracts vs. Smart Contracts
- What are the benefits of smart contracts?
- Smart Contracts in Supply Chains
