The Bitcoin network provides bitcoin owners with a unique sort of security – proof-of-work. Proof-of-work, or PoW, is a method for securing a network in a decentralized manner. The process, however, is incredibly energy-intensive, requiring thousands of competing processors, or miners, to perform redundant calculations. Other forms of security, say that underlying instruments listed on the Nasdaq stock exchange, rely on cheaper centralized methods.
