Most full nodes also serve lightweight clients by allowing them to transmit their transactions to the network and by notifying them when a transaction affects their wallet. If not enough nodes perform this function, clients won’t be able to connect through the peer-to-peer network—they’ll have to use centralized services instead.
Many people and organizations volunteer to run full nodes using spare computing and bandwidth resources, but more volunteers are needed to allow Bitcoin to continue to grow. This document describes how you can help and what helping will cost you.

Contribution and Decentralization
It is truly important to read the Bitcoin White Paper, A Peer-to-Peer Electronic Cash System (Satoshi Nakamoto), as it lays the foundational principles of this technology.
Beyond reading, consider contributing to the network with a Full Node. Running a full node is fundamentally important: it's not just a technical act, but a direct contribution to the decentralization, security, and integrity of the entire network. The experience of knowing you are actively validating every transaction and every block, without relying on any third party—is the true meaning of being sovereign in Bitcoin.
I have one working 24 hours a day, 7 days a week; it is my small contribution to the network, and I hope this page helps you understand everything related to the Bitcoin ecosystem.
Contributions will go towards a hosting plan on a dedicated server.
It would be great if those of us running full nodes selflessly could be donated a small part of Bitcoin, at least I think it would be fair. 😉
