Topic: How do I check the blockhain? (Read 289 times)
You can check the blockchain by using Blockchain Explorer. which is a tool or website. Choose an explorer relevant to Bitcoin, such as Blockchain or blockchain.info. Which will help you to search the complete information of a particular block. If you want you can see all the information like transaction history balance and individual block, sending address. Remember that blockchain will give you complete transparency on the overall situation.
Hello, when I make a transaction, sending or receiving, is it recomended to check if it's valid on the blockchain?
How do I do it?
Running my own node helps checking it? Thank you

Well running your node could be of a great help but are you ready for the datas interm of handlingand storage althoughthe job is almost done to the fullest by the nod e it self, if you are only looking forward to just tracking your transaction or checking transaction history and validity you could could just make use of the sites that provide such tools we have the popular ones and I guess they must have shown or told u one or two in this thread , besides there are the most used ones
This two site offer almost all the tool you seek in term of your question , perhaps you could even get more knowledge from operating it
The full node actually is the one that needs more space since it stores all blockchain data’s and many more are still being stored, a 500GB plus should be ok for smooth running, you can just buy HDD instead of SSD since the former is cheaper. As for prune node it depends on the amount of space you want it to use then, I think you can specify it.
I have heard many users complaining about syncing issue when using part of a blockchain node instead of a full blockchain node. But since I don't have enough space on my device, I guess I'll have to rely on third party websites and platforms for now. And as for HDD, there isn't any hardware slot or space to add or extend the hard disk. Bad Luck. 
1. How much disk space one would need to run full node and prune node? (I don't think I have enough space for either of them, 240GB SSS, sad life).

2. How do we setup a blockchain node? (Again, I have no idea how this works, zero knowledge).
You can use bitcoin core as the software to run a node. Below are links of how to run a node and also where to download the bitcoin core app.

You can download bitcoincore from the link below
https://bitcoincore.org/ and then you install them, here is how to https://en.bitcoin.it/wiki/Help:Installing_Bitcoin_Core
If you run a prune node, you can check only your own transactions and if you import a new address, you have to redownload the blockchain.
If the purpose is to check any transaction without relying on third parties, a prune node wouldn't be helpful and you would have to run a full node.

That’s true but since a prune node can have some past blocks stored too, that means not all new address that needs to be verified it has to download past blockchain because some of the recent address might already have its block already on the prune node. It will redownload the entire blockchain again only if the address to be verified is older than the main address running the prune node?

You can check your transaction history in your wallet. In every wallet always have the transaction history to check the status of transaction and in there's not only transaction status, there is tx hash code or link transaction explorer to see your transaction.

check transactions on the blockchain in link "blockchain.com/explorer'. Just drop your transaction ID into the search bar and it will show you everything about its status. As for running your own node, that gets a bit more technical, need some programming knowledge for that How do I do it?

I use a watch only wallet on my tablet to my HW, with orbot on int. But I was thinking, what if the watch only is a fake and simply shows me something that doesn't exist on the blockchain? shouldn't I check at least 1 of the transactions, to confirm that's indeed on the blockchain?
You can check your transaction on a block explorer to make sure it's valid and it has been confirmed. But what makes you think the watch-only wallet may be fake and shows wrong information? Didn't you create the watch-only wallet by yourself? What software did you use for creating your watch-only wallet?
By the way, note that if your transaction has received 1 confirmation, it will likely receive more confirmations, but you shouldn't consider a transaction with 1 confirmation final especially if you have received a big amount of bitcoin.

To be sure that your funds are "real", you can just check the balance of your address (or addresses) on a BTC explorer or with Mempool as stated above.
For example, if you want to check the current balance of address 16uAEbhT9qeiWZt23Jiq8UJg4wvKz6aqH3, you go to https://mempool.space/fr/address/16uAEbhT9qeiWZt23Jiq8UJg4wvKz6aqH3
Your wallet is supposed to give you the transaction id related to your deposits, in the details of transactions. You can always check them to be sure that everything is fine. No matter if you use mempool.space, your own node or another explorer.
Hmm I see.

I also have a fullnode downloaded on another device, so I was wondering if I could check the blockchain from it, than it would confirm it
*edit I downloaded the full node by curiosity, never used it neither I run a wallet there

When you make transactions using platforms like multichain wallets or Metamask, they usually give you a receipt. To double-check and feel more secure, you can always verify the transaction on the blockchain explorer. Each blockchain has its explorer, like BSC has bscscan.com, and Ethereum has etherscan.io. Just Google it, and you'll find the right one for your blockchain. It's like having a digital receipt for your digital transactions, a way to ensure everything went smoothly and as expected in the vast world of cryptocurrencies.
List of useful Bitcoin block explorers
Many Bitcoin block explorers for you to choose from the list. It's worthy to remind you that when you use Block explorers to check transaction history especially if it is yours, you must use Tor connection.
You can use Watch-only wallets to check balance and transaction history, can not spend coins from Watch-only wallets.

People can use watch-only. But also they can use their wallet with seed phrase or private key to check the balance, not necessary to use blockchain explorer, except you want to track the transaction of coins that is not sent from or received on your wallet.

It will redownload the entire blockchain again only if the address to be verified is older than the main address running the prune node?
Yes, you have to redownload the entire blockchain.Every time you import a new address/private key or a new wallet in bitcoin core, it has to rescan and that's not possible if you are running a prune node and you don't have the entire blockchain.
Note that there is no way bitcoin core can know when your address was first used without having access to the entire blockchain.
If you run a prune node, you can check only your own transactions and if you import a new address, you have to redownload the blockchain.

Aside even running a full node if it is too large to keep the entire blockchain you can simply run a prune node and specify the amount of size you want it to occupy. Prune nodes is same as full node in terms of privacy

Yes you can run your own full node to avoid using the public blockchain explorer which could affect your privacy. Also just as said when when receiving a transaction do not rely total because it is in the explorer, have Atleast 3 confirmations or 6 confirmations which is considered the most safest option to avoid anything like a chain reorg in the process which could render even a 1 confirmation transaction invalid.
Running a node is different and you will have to spend money to have more space because you will need lots of space because running a node means you will download the data in the blockchain. <...>
I wouldn't say that's entirely accurate. You don't necessarily need to spend money to run a full Bitcoin node. Nowadays most regular computers have plenty of disk space for storing the whole blockchain.
As of now, the Bitcoin blockchain takes up around 530 gigs. but even a cheap laptop these days likely has at least a few terabytes of disk space. and So for most folks, storing the blockchain wouldnt be an issue or require buying new hardware.

There are other blockchain explorers if you search for it but if you don't want to then you can use the blockchain explorers that are provided by Mia Chloe. I always use mempool.space when I want to check something. To check your transaction, you need to copy the address if you can't find the transaction ID but if you do then you only need to copy and paste the transaction id into the blockchain explorer.
You don't need to run a node to be able to check or monitor your transaction status on the Blockchain.you can make use of
- Blockchain Explorer; all you have to do is put in the transaction id
- Mempool
Hello, when I make a transaction, sending or receiving, is it recomended to check if it's valid on the blockchain?
As I ready said by others, there are many block explorers that can be used to check if a transaction is valid. Just take note that being valid is not enough and you should never accept an unconfirmed transaction. It's possible that a transaction is now valid now but unconfirmed and becomes invalid after a while.
