The P2P Mechanism: Connected by a Network of Trust
Unlike fiat currencies issued by governments or central banks, Bitcoin operates without a central authority to manage its issuance or circulation, yet legitimate and trustworthy transactions
continue to take place. One of the systems supporting this trust mechanism is P2P.
P2P stands for “Peer to Peer,” meaning from one individual device (Peer) to another.
In other words, it refers to a network of trust formed when individual devices (Peers) trust one another, without the need for a central server to manage or oversee the system. Any
device can serve as a Peer—whether a desktop computer or a laptop—and the system is designed so that devices connect with one another to exchange information or share data in response to requests from other devices.
The P2P mechanism was originally used in file-sharing software, but it has come into the spotlight as the mechanism underpinning transactions for cryptocurrencies, including Bitcoin.
Bitcoin uses the P2P method to share transaction data and operates without a central administrator.
However, the absence of a central authority means there is no mechanism to guarantee data integrity. To address this, the blockchain—which validates valid transactions and records and links a chain of past transactions—has been introduced to ensure both integrity and reliability.
