Right now we have 5800 nodes worldwide, how many nodes we need more?
How it would help if we would have at least a million nodes?

How much money do you have? Running 100 nodes {configured correctly} will take a bunch of bandwidth and also storage space. How are you

planning to accomplish this? The thing about a decentralized network is this.... the more distributed these nodes, the better for the network. If

a large quantity of these nodes are concentrated in a central location, then attacks would be targeted towards these locations. Let's say you run

these nodes on a data centre and this data centre goes down, then you will take down a large amounts of nodes at the same time. Sad

I dont think that there is an ideal number of bitcoin nodes required, i just think that it is the more the merrier. i run one myself and i find it relatively cheap to run and it dosn't take up much hard drive space either, with the latest hard drive sizes it would take years.

5000 seems to be a nice sweet spot for the amount of usage bitcoin is getting. If it went lower it would be a problem and big blockers want to lower the node count while raising the usage.

Oh and dont forget, it's not only about node count. If a big company fills a building with nodes, that counts a single point of failure, so it's useless to strengthen the network. Nodes must be spread all over the place by individuals, any other models are weak, hence why conservative blocksize is a reasonable tradeoff.

I think that while we have some considerable numbers for nodes, it would be better to see more nodes popping up as time drags on so that the network will be able to scale with everything properly.

For right now I don't think there's a huge need to have a massive number beyond the 5k we have, but more will always be nice to see for sometime in the future.

More nodes mean better distribution of bitcoin ledger which will be helpful to secure bitcoin network from several types of attack including governmental shutdown of nodes in few countries.

I dont really care how many nodes are there and how many more to help the bitcoin transactions work faster. The thing is, nodes are just a stocks of datas of transactions. So if you say more nodes, then more keepers of the transactions or records, better right?

How so, and how ia that useful. In general nodes dont provide benefit to the network are are just wasted resources.

It would be more valuable to spend resources on buying coin or developing apps etc

A node will verify blocks and transactions. They will see if the transaction and the block fits the protocol rule. If they don't they will reject the transaction. Lets say we don't have nodes and only miners. The few big miners out there can enforce their own rules.

as long as they are not fake node, for sybil attack they does help otherwise not they are dangerous, you can always check carefully the node that tell the true but it's still possible to perfom it

A sybil attack is hard to prevent. Its hard to find out if the node is sending the accurate information. The more nodes, the harder it will be to connect to the rogue nodes.

The more the better for tx propagation and block validation. I think 5000 is good enough, if it grows with the number of txs, not reduces.

5000 is not that big of a deal as number. We all know how easy it is for an entity to host hundreds of nodes from datacenters in order to gain a fair share of the total node percentage. Especially if you team with with others that do the exact same thing. It may turn out to be an expensive practice if you happen to keep them running for a long time, but depending on what the intentions are, it might turn out to be a worthwile action after all.

the more nodes = delay in propagation. because it takes time between each node getting data to check it and move it on.
but
the more nodes = more copies of the blockchain. so if something bad happens in one locality there are many copies in other localities that no one cares what happens in small area's

more nodes is not about propogation efficiency but about diversity and reducing risk of targetting limited numbers of data holders

5000 nodes is already a good deal and I think it's fair enough. However with a bit more it could be better, as 6000 nodes, let's try that to see how it works, if it's better or not.

Why do we limit the number of nodes speaking only with numbers? I really don't understand why we say 5000, 5800 or 6000 nodes. I would like to mention that some time in the past the nodes were more than 10.000. I believe the more the better about the network. Maybe the question is the same like as the core developers do we really need. Moreover the more nodes the less the danger of double spending according some researchers in Switzerland. At last we have not forget that a node is a form of consensus in case of soft or hard fork that means has voting rights.

give me your cryptos

In a our decentralised network which is already pretty large, the amount of nodes don't really help, besides preserving the integrity of our data. So it doesnt matter if we have a million, because if 500,001 of these nodes are malicious, we're doomed.

Thanks for your time, but i am trying to determine how much it would be helpful if i setup couple nodes.
I want to feel that i am doing impact, would something will change to the better if i setup at least 1-100 nodes?

It would help - everybody should run at least one full node on a good connection to help with the network breadth. one node with good bandwidth and full blockchain is much better than 100 nodes on crappy network lagging behind, these do more harm than good.

Nodes dont help with decentralization so long as mining is centralized, so we dont need more nodes.

We need more distributed mining.

I think the number of nodes as large as possible, 5800 is a stable figure. however, I think we need a little bit more, probably 6500. this will improve things. you should not have too nhìu nodes. will be expensive if the number of nodes to be redundant

You not read Bitcoin introduction by Satoshi Nakamoto:

http://www.buywithbitcoin.info/satoshi

Network
The steps to run the network are as follows:
1)
New transactions are broadcast to all nodes.
2)
Each node collects new transactions into a block.
3)
Each node works on finding a difficult proof-of-work for its block.
4)
When a node finds a proof-of-work, it broadcasts the block to all nodes.
5)
Nodes accept the block only if all transactions in it are valid and not already spent.
6)
Nodes express their acceptance of the block by working on creating the next block in the
chain, using the hash of the accepted block as the previous hash.
Nodes always consider the longest chain to be the correct one and will keep working on
extending it. If two nodes broadcast different versions of the next block simultaneously, some
nodes may receive one or the other first. In that case, they work on the first one they received,
but save the other branch in case it becomes longer. The tie will be broken when the next proof-
of-work is found and one branch becomes longer; the nodes that were working on the other
branch will then switch to the longer one.

As far as I know, Nodes are the computer itself that are connected in the Bitcoin network. Saying that it does not help even if it is more nodes. In the nodes are the list of transactions that are being in the run. Hope it helps.
