Without tor your ip adress then making trasactions is saved to blockchain
1. The IP address isn't stored on blockchain, unless you meant blockchain.com the block explorer?
2. IP address shown by blockchain.com is IP of the node which relay the transaction to blockchain.com node. It's unlikely the sender run full node and directly connected to blockchain.com node.
Tor obfuscates your entry and exit point to the network. Your exit node can only track you if they are also controlling your entry node and can link your entry and exit traffic between the two nodes, effectively mounting a Sybil attack.
Is this a risk worth thinking about? How many entry and exit node combinations exist on the TOR network? Do the numbers change and increase regularly or are they more or less the same for years?
