Replace Centralized

"Traditional monetary systems depend on banks or central authorities to maintain records of who owes what to whom, which provides efficiency and security but concentrates power and profit in the hands of the record-keepers. A decentralized system distributes record-keeping among networked individuals or institutions and requires safeguards so that no single participant can tamper with the shared record. The network must also provide incentives and common rules that encourage participants to act in the interest of the system."
