Summary. Contracts, transactions, and records of them provide critical structure in our economic system, but they haven’t kept up with the world’s digital transformation. They’re like rush-hour gridlock trapping a Formula 1 race car. Blockchain promises to solve this problem. The technology behind bitcoin, blockchain is an open, distributed ledger that records transactions safely, permanently, and very efficiently. For instance, while the transfer of a share of stock can now take up to a week, with blockchain it could happen in seconds. Blockchain could slash the cost of transactions and eliminate intermediaries like lawyers and bankers, and that could transform the economy. But, like the adoption of more internet technologies, blockchain’s adoption will require broad coordination and will take years. In this article the authors describe the path that blockchain is likely to follow and explain how firms should think about investments in it. The Hype We’ve all heard that blockchain will revolutionize business, but it’s going to take a lot longer than many people claim. The Reason Like TCP/IP (on which the internet was built), blockchain is a foundational technology that will require broad coordination. The level of complexity—technological, regulatory, and social—will be unprecedented. The Truth The adoption of TCP/IP suggests blockchain will follow a fairly predictable path. While the journey will take years, it’s not too early for businesses to start planning. Contracts, ...

• • • • • • • • Which Statement is True About Blockchain? Understanding the Fundamentals of Blockchain Technology Decentralization, Security, and Immutability One of the key features of blockchain is its decentralization. Unlike traditional systems that rely on a central authority to verify and approve transactions, blockchain allows all network participants to verify transactions in a peer-to-peer manner. This makes the system more secure, as it reduces the risk of a single point of failure. Furthermore, the use of digital signatures and consensus mechanisms ensures that transactions are tamper-proof and immutable. Public vs. Private Blockchain There are two types of blockchain: public and private. Public blockchain, such as Blockchain Use Cases Blockchain has several use cases in different industries, including finance, healthcare, supply chain, and more. In finance, blockchain can be used to facilitate cross-border payments, reduce fraud, and increase transparency. In healthcare, blockchain can help secure medical records and ensure patient privacy. In supply chain, blockchain can enhance transparency and traceability, reducing the risk of counterfeit products and promoting ethical sourcing. Blockchain Limitations Despite its potential benefits, blockchain also has its limitations. For instance, scalability remains a challenge, as the current technology is unable to handle large volumes of transactions. Additionally, the energy consumption required for mining The Future...
