Are IPs stored in the blockchain?

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!

No, but some people decide to store it anyway, but they don't know the IP is actually IP the sender or another full node which propagate the transaction.

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 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.

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.

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.

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.

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.

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 depends how you create the transaction.
Your IP when your broadcast a transaction through bitcoin core, is revealed to the other nodes that receives the broadcast. Which is approximately 10 other nodes.
ChainAnalysis a firm specializing in tracking bitcoin transactions used to have 10.000 BTC nodes just to snoop on who was where when they broadcasted their transactions.

On a second thought, any transactions you do through Binance, Kraken or Coinbase has a registered IP of your account and is sold to companies like Chainanalysis or sent to IRS (if in US) like Coinbase does.

You can also go to blockchair.com enter your TX ID and you will see how "private" your transaction is...
