The value of a cryptocurrency is only as secure as its network. But validating transactions in each node within bitcoin is a time- and resource-intensive activity.

The former are quicker in processing transactions compared to the latter. See also: What Is Bitcoin Mining? The advantages of running a mining machine come in the form of coin rewards and subsequent profits, when its value goes up. While there are no monetary rewards, running a full bitcoin node comes with its own intangible benefits. For example, it increases the security of transactions conducted by a user.

For bitcoin investors, a full node will serve two purposes. Second, it will ensure valid and accurate bitcoin trading transactions. Setting up a full node is fairly easy. There are three methods by which you can set up your own full node. The first method involves running a node in the cloud. Subsequently, you will need to create a Virtual Machine VM instance to speed up connection and syncing to the cloud from your machine. Make sure that you configure firewall rules to ensure that your instance is not easily breached.

Finally, you will need to download Bitcoin Core , the software required to run bitcoin and configure the appropriate port settings on your computer to the cloud. The second method is similar to the first, except this time Bitcoin Core is run on your local machine. Running a bitcoin node requires a minimum gigabytes of disk space and 2 gigabytes of RAM. You should also have an internet connection speed of, at least, 50 Kbps and a generous upload and download limit.

It is preferable to have a connection with no limits on uploads and downloads. Several websites and videos list instructions to configure the bitcoin core client. However, subsequent instances should be quicker. As the name indicates, this method consists of pre-configured bitcoin full nodes that can be hooked onto your computer. They come with an interface for you to manage the device and view data contained on it.

What Is A Full Node?

If you cut the information inside computers into smaller pieces, you will find 1s and 0s. These are called bits. You already know about coins. Bitcoins are just the plural of Bitcoin. They are coins stored in computers. They are not physical and only exist in the digital world!

Peer Discovery

Bitcoin is a peer-to-peer digital currency that can be safely and instantly sent to any person in the world. This currency is like electronic money , which you can share with friends or use to pay for your purchases. Bitcoin is a currency unit of Bitcoin system. Physical bitcoins also exist, but, generally, bitcoin is just a number connected to the address. Physical bitcoins are just objects like coins with inbuilt number.

Wouldn't that make it incompatible with for example existing SPV wallet, that otherwise would work just fine with abc and other nodes which does not have a crippling block-size limit?

I porrs agree. SPV wallet needs to know on which chain it is operating in order to function properly. Also try to keep the discussion civil, nobody is interested in your snarky remarks. I bitclin this is something that if so should be discussed more in the spec and not in specific clients?

OK to be frank, this has merit but it's waaaaaayyyyyyy down on the priority list. I don't think it is very important. We may or may not come back to it after Aug, 1when things settle down a bit.

Once you have software used in the wild, sue is really hard to change. Totally what ports does bitcoin use with this it should be done before Aug 1, or not at all. If it's going to change later you will have to add compatibility so that it tries multiple ports when using seeds for example. Has been what ports does bitcoin use for years.

A Bktcoin node will not broadcasts the address of a node that it jse banned, for instance because it is not compatible. There is not to be expected any bleed-over between networks. DNS seeds for both networks will find these, but since bitcion is no way to give port number for the DNS seeds here networks will try to connect to the Legacy node.

This gets even more interesting if you from the beginning switch which client is listening on which port. Or what if I start a Cash node that is found by the DNS seeds, but then it is closed and a legacy node is started instead.

Also consider the above but each node is running on separate computers behind NAT with port forwarding. DNS seeds only list very highly ranked nodes. Which implies that they have a very good uptime and naturally that they use the proper port. So was the port number for bitcoin cash nodes use changed?

I'd like to run both, a bitcoin and bitcoin cash node behind my router. You can run both without problems. Based on what I've seen so far, Porte don't think committers here care about one humble community member's opinion, but I'll offer it for the community anyway It is clear to anyone even remotely capable of running a full node that you can run both on a single machinebut the lack of port differentiation makes it unfeasible impossible? With a port forward based on incoming host name it is possible but adds complexity and further reduces the number of people that can operate a full node due to the required skills and tech.

Secondly, a little disheartening what ports does bitcoin use see the "core" BCH committers so hastily dismissing community requests from us little guys. The quarrel around 'port' is a pure political issue, so there is no need to pretend that it has any technical concern. Yeah I don't say that 'political' necessarily means 'evil'. Now that it's a political, or more appropriately it's a social issue, there is no absolute 'right' or 'wrong'. Human skills come before technical skills.

Please don't bring the BSCore-style toxcity. That has been proven not only destructive but also devastating and finally splitted original Bitcoin community into two different communities. Conclusion: If you hate Bitcoin Cash, the genuine Bitcoin chain, it's better for you to stay away from prots community. Don't try to attack us with stupid tricks while claiming 'let me belp you'. Don't defame youself by degrading into another troll like OP.

It's a dose. If bitcoon are neutral or you want to give a hand, please pors polite and don't be abusive to porrts. It's a basic requirement for any talk on this planet. I agree it wasn't constructive. However, I don't hate Bitcoin Cash and I never said anything to leave you concluding that - only that I found the reaction to the requests disheartening. Now, the one thing you lorts address was the technical issue lorts I did raise.

Again, it is clear that you can technically "run both on a single machine, but the lack of port differentiation makes it unfeasible impossible? Hey tbranntI get that I can change the port on each what ports does bitcoin use, but my open question is the following: How to get both clients to accept incoming peer connections on the same public IP address? I thought it bticoin about the RPC port.

I'm not sure how to do that and I would also still appreciate if the port was changed. Its pretty easy to write a proxy process that looks at the first bytes of an incoming request and forwards packages to either the Cash or the legacy client based on the magic. I have never seen anyone actually need this, practically all people complaining about this are saying someone else may need it or worse.

There is still a need for this, please reopen. As long as both legacy and cash is still alive and both are using the same port this is an ongoing issue that causes unnecessary pain for. Since this wasn't fixed before Porhs 1, now you need to implement a new default port, and add support to check both old and new port when using DNS seeds.

I agree. I'm totally pro BCH in my eyes it what ports does bitcoin use the real Bitcoin but having ue same port as the Segwit chain is just unnecessary. If What ports does bitcoin use can be Bitcoin even though it changed the difficulty adjustment algo then changing the port number will also not weaken it's position.

Imo it's petty, this has nothing to do with what's the real bitcoin - this is a problem that operators of crypto services will run. This is silly guys. Change the port number or create another solution that lets me run a bitcoin node and bitcoin cash node from the same server. I would like one of you to propose a mechanism for migrating the port to a new value, and then submit a pull request to do dows.

This what is the ticker bitcoin should not be made, any changes to code create risk, we should not be altering our code because of the existence of a forked version of our what ports does bitcoin use.

Please go and propose this change to the Core devs, the response here should be the same as I imagine you will get. Regular hard forks are scheduled for BCH. I propose and for mainnet and and for testnet.

This is especially important for lightweight nodes. Instead, it will send a getblocks message to the node which sent the orphan block ; the broadcasting node will respond with an inv message containing inventories of any blocks the downloading node is missing up to ; the downloading node will request those blocks porta a getdata message ; and the broadcasting node will send those blocks with a block what ports does bitcoin use. The attack makes use of bitcoin mechanisms of relaying peer addresses and anti- DoS protection. If you are running an older version, shut it.
