Bitcoin Q&A: What is the role of nodes?

The role that full nodes play in security of the network. People focus a lot on mining, which has a fundamental role in the network but is not necessarily the most interesting feature of the constellation of technologies involved. The Border Gateway Protocol (BGP) is the most essential protocol underlying the world's routing system, and you use it every single day without knowing it, just as you are oblivious to the vast filtration system allowing you to drink clean water from a fountain. A node is a computer that is participating the global peer-to-peer Bitcoin network. They propagate transactions and blocks everywhere. Full nodes act independently as authoritative verifiers. Onion routing. Double-spending protection. Levels of isolation for untrustworthy nodes. Why would you run one? To be in control of your money - your keys, your money. You don't trust anyone else to tell you what the truth is, you cross-check every claim yourself. Be part of the revolution in money. This is part of a talk which took place at the JW Marriott Sahar (International Airport) on March 26th 2017 in Mumbai, India: RELATED: Lightning, full nodes, and miners - Hard Promises, Soft Promises: Promoting Autonomy instead of Authority Innovations in wallet design - How to get people to care about security - Andreas M.

Andreas, it's my understanding that Full nodes validate transactions and place them in blocks. But a full node must have hashpower behind it. "Full" non mining nodes can't validate transactions for the network and only receive and validate blocks that are already on chain. They have practically no effect on the network outside of your personal benefit. Can you explain if I have a misunderstanding?

What is the use of building your own node. I mean how is it profitable for me to know that the transaction occurred. Plz Reply

So it is the nodes that secure the block chain network not the miners.

Stupid response. Expansion of scale without expansion of interest is the path to centralization. Want more mining centralization in China? Keep believing that you shouldn't bother with mining. Do you know what separates the average person from being a "miner"? NOTHING! Do you know what separates a node operator and a miner? Miners get paid for participation on the network, nodes do not.....

#aantonop  I understand that miners receive BTC for the work they do in creating the currency, which is well deserved as they not only have to purchase very expensive hardware, but have to keep updating it regularly to keep pace with the ever increasing difficulty level to do so. It would seem, at this stage, that although running a full node is considered very important and desirable (probably vital) to protect the code and validate the transactions, those who run a full node (currently 123GB of data last I checked) 24/7 are not compensated (at all) for the costs they are incurring to do so. To that end, it seems reasonable to me that a small payment should be introduced and paid to full node operators for providing this service, which could only be viewed as beneficial in the protection of the entire network. A small payment would also incentivise others to run full nodes and so further strengthen the system. I guess the issue then is, if this were to happen, how would it be levied or paid and by whom? Your thoughts?

But how do you get a full node?

Thanks for another informative video. I have a couple questions though. 1) Should I run a full node behind a vpn? 2) I've opened port 8333 and have 40 active connections. How many connections can I expect and will this interfere with online gaming or hogging the bandwidth?
