What is the year of when the decentralized network started?

The concept of a decentralized network began to take shape in the early 1980s with the development of technologies like ARPANET and the emergence of peer-to-peer networking. However, the decentralized network as we know it today gained significant traction with the introduction of blockchain technology in 2008, when Bitcoin was proposed by an anonymous entity named Satoshi Nakamoto. This marked a pivotal moment in establishing decentralized systems for digital currencies and applications.
