Blockchain does not store IP addresses but blockchain explorers do store IPs of their visitors. People asked for decentralization, and privacy but unfortunately they in their turn forget to protect their privacy. Have you ever thought of losing your privacy because of visit blockchain explorers to check your transactions' confirmations?

Many people do that and it breaks their privacy.

If caring about privacy, doing all on Tor network. Tor browser to visit any site, and to check bitcoin transaction confirmations on explorers as well. Don't protect your privacy in half because you will lose them all.

You can use this to your advantage too, because you search for several known wallets and they also tie that to your IP address and you confuse them even more. Wink

A lot of these sites also detect when you use Tor and then they block those IP's... so the next person using the IP would also be blocked. (That is to say if you not going through a service provider that use DHCP and also using the same exit nodes. Roll Eyes

Some people are even dumb enough to go through all the KYC requirements to use exchanges and then they get linked to their other activities in that way, when they re-use the same Bitcoin address to deposit or to withdraw.

It's not only blockchain explorers, full nodes, wallet servers, online wallets all might store the logs with IP addresses and the requested address. We even know that some do, because companies like chainanalysis run some Electrum servers to harvest this sort of data.

So, even if blockchain doesn't store addresses, you still should worry about it if you don't want anyone in the world to link your IP with your coins. Research how to run Bitcoin through TOR.

IP's are not stored in the blockchain, only websites could able to store your IP address. It is the reason why other people uses VPN or Tor browser to change their IPs and hide or save their privacy. Don't you worry about blockchain technology because it is completely safe and secured that makes it very difficult for everyone to hack or change its system.

No and never! If IPs are stored, then bitcoin wouldn't have been used for illegal things! But it's not! You can get a good idea of what is stored in bitcoin block from the below article,

https://www.investopedia.com/terms/b/blockchain.asp

- Blocks store information about transactions like the date, time, and dollar amount of your most recent purchase from Amazon. (NOTE: This Amazon example is for illustrative purchases; Amazon retail does not work on a blockchain principle as of this writing)

- Blocks store information about who is participating in transactions. A block for your splurge purchase from Amazon would record your name along with Amazon.com, Inc. (AMZN). Instead of using your actual name, your purchase is recorded without any identifying information using a unique “digital signature,” sort of like a username.

- Blocks store information that distinguishes them from other blocks. Much like you and I have names to distinguish us from one another, each block stores a unique code called a “hash” that allows us to tell it apart from every other block. Hashes are cryptographic codes created by special algorithms. Let’s say you made your splurge purchase on Amazon, but while it’s in transit, you decide you just can’t resist and need a second one. Even though the details of your new transaction would look nearly identical to your earlier purchase, we can still tell the blocks apart because of their unique codes.

Hope this clears up your mind!

Depends on where or how IPs will be stored to prevent Bitcoin from being used for illegal things. Any kind of Companies and people having access to people's IP is its self "illegal" because it violate the fundamental right to privacy in many countries law. Privacy or The Right to Privacy in environment where evil, lawlessness, immorality, uncertainty etc reign is a good thing.
IPs could be thoroughly encrypted and stored on "public network" as long as it's done transparently, safely/securely, immutably. If someone commits a serious crime, the police could have access to the criminal IP... I believe this should be done on thesame decentralized network, for the sake of immutablity, clear rules, accountability, privacy, security, etc features of the Blockchain/decentralized-tech.
In my opinion, any kind of people shouldn't have access to people's IPs if the owners did not do things that deserve getting their IPs exposed to untrustworthy/immoral people

Blockchain itself doesn't store any IP address for bitcoin transactions. But your IP address would be exposed or can be logged in some other way. You may read this question made on Bitcoin Stack Exchange, How do I see the IP address of a bitcoin transaction? There is some information which would be helpful for you.

Read more on Your IP address can be logged

Quote here,

Quote from: https://bitcoin.org/en/protect-your-privacy#iplog

Because the Bitcoin network is a peer-to-peer network, it is possible to listen for transactions' relays and log their IP addresses. Full node clients relay all users' transactions just like their own. This means that finding the source of any particular transaction can be difficult and any Bitcoin node can be mistaken as the source of a transaction when they are not. You might want to consider hiding your computer's IP address with a tool like Tor so that it cannot be logged.

Hi all,

when a new transaction is created and spread over the network, is the IP of the original creator of the transaction stored?

Just wondering, because this would harm privacy.

Thanks in advance!

Sakurro

no, it's not stored in the blockchain...
