How do I check the blockhain?

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

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

Yes I will recommended to verify the status of your transactions on the blockchain. It will ensure your transaction validity and completion of your transaction. You can do this task just by checking the transaction details on a any blockchain explorer

If you are running your own node then its provide more decentralized  way to verify your transactions. When you run a node, you validate transactions without relying on third-party services. In node you just have to connect wallet with node and here you could check transaction here with full privacy.

As a normal user , I will recommend sample site (Blockchain.com) which is easy to check but if you have good knowledge of node then go for advance transaction checking

As mentioned above, you can do it with a block explorer but whatever wallet software you're currently using should give you the number of confirmations, and also link you to the block explorer directly, whenever you receive or send funds.

It is not necessary if it is not a paper wallet. So far you have access to your wallet and you can check the transaction directly on the wallet.

How do I do it?

If you paste the txid of the transaction on a blockchain explorer, you will see the details.

Example of explorer is https://blockchair.com

If you do not want to depend on other nodes, you have to run your own node. This can help you have privacy. This is not related to your question about transaction.

You really don't need to double check all the stuff going in and out of your wallet. Especially after it's confirmed - that data gets stored on the blockchain so your wallet grabs it from there anyway.  Kinda pointless to keep rechecking. 

But say something seems weird or you just wanna peek at the details on an independent blockchain explorer site.  Those sites can get your IP address and other private stuff then pass it to who knows who and  better to cover your tracks. So I'd say throw on a VPN or use Tor if you're worried about that.

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.

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. 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.

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.

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.

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

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?

[hosseinimr93]

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.

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.

Why Tor must be a must? It is only recommended for people that want anonymity. Such people should also be connecting their wallet to Tor.

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.

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.

Hmm I see.

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?

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

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.

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.

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
