Fiber optic networks are essential to the functioning of blockchain technology. In short, blockchain is a decentralized system that relies on a distributed network of computers to maintain a digital ledger of all transactions. Allowing for secure, transparent, and immutable record-keeping, this technology has a wide range of applications in finance (cryptocurrency for example), supply chain management, and other industries. Offering high-speed, low-latency data transmission capabilities, fiber optic networks are the ideal choice for supporting the complex and data-intensive operations of blockchain technology.
