Welcome to 15.S12 Blockchain and Money, Fall 2018!

Hey there! Welcome to the exciting world of blockchain and money. In this course, we will explore how blockchain technology is revolutionizing the way we think about and use money. Whether you’re new to the concept of blockchain or already have some knowledge, this course will offer you a deeper understanding of its implications on the financial world.

What is Blockchain?

Before we dive into how blockchain is changing the way we think about money, let’s first understand what blockchain actually is. In simple terms, blockchain is a decentralized digital ledger that records transactions across a network of computers. Each transaction is stored in a block, which is then linked to other blocks in chronological order, creating a chain of blocks – hence the name blockchain.

How Does Blockchain Work?

When a transaction is initiated, it is verified by a network of computers (or nodes) through a process called consensus. Once verified, the transaction is added to a block along with other transactions. This block is then added to the existing chain of blocks, making the transaction immutable and secure.

Benefits of Blockchain

Blockchain offers several benefits, including transparency, security, and efficiency. Transactions on a blockchain are transparent and can be viewed by anyone on the network. Additionally, the decentralized nature of blockchain makes it resistant to fraud and hacking. Furthermore, blockchain eliminates the need for intermediaries, reducing transaction costs and speeding up the process.

Blockchain and Money

Now that we have a basic understanding of blockchain, let’s explore how it is changing the way we think about money. Blockchain has the potential to disrupt traditional financial systems by providing a secure and efficient way to transfer value. With blockchain, individuals can send money anywhere in the world without the need for a bank or payment processor.
