Blockchain Practice Exam

Blockchain is a decentralized and distributed digital ledger technology that securely records transactions across a network of computers. Each record or "block" contains a list of transactions and is linked to the previous one, creating a chain of blocks, hence the name "blockchain." This technology is known for its security, transparency, and immutability, making it ideal for applications like cryptocurrency (e.g., Bitcoin), supply chain management, and digital contracts. Blockchain eliminates the need for intermediaries by allowing peers to directly verify and record transactions, reducing fraud and increasing efficiency.

Certification in Blockchain refers to a formal credential that validates an individual's knowledge and proficiency in blockchain technology. Obtaining a blockchain certification demonstrates a person’s ability to understand and apply blockchain concepts, tools, and practices to real-world problems. The certification process typically involves comprehensive learning modules on blockchain architecture, consensus mechanisms, smart contracts, and blockchain applications. This certification can be pursued by professionals in various industries, such as finance, healthcare, and supply chain, who wish to deepen their understanding of this transformative technology.
