The first Bitcoin (BTC) transaction received to an IP address ?
« on: February 11, 2019, 08:54:25 PM »
On February 04, 2010 I made a forum post requesting that someone might try to send a Bitcoin transaction to my static IP address in the UK.

I had two windows terminals running Bitcoin and MT4 software and I wanted to see if the lowest subnet IP machine would receive the transaction.

Here is the original request and the response from the sender of the transaction(s) bitcointalk forum member 'SmokesTooMuch' (account 13).


Surely 'Satoshi' had already tested this functionality !? However, as far as I know this is/was the first Bitcoin (BTC) transaction received to an IP address ?

Port forwarding forwards a port to one computer.  It tells the router which computer handles connections to that port.  So that's the computer receiving.

If you didn't set up port forwarding, then incoming connections won't go to any computer, and attempts to send to that IP would just say it couldn't connect to the recipient and nothing is sent.  When sending by IP, you still send to a bitcoin address, but your computer connects to that IP, gets a new bitcoin address from it, gives the transaction directly to the them and confirms that it was received and accepted.

Someone should post their static IP so people can try out sending by IP and also give that user free money.

There's a 32-bit checksum in bitcoin addresses so you can't accidentally type an invalid address.

If 4) you send to a recipient who has abandoned or lost their wallet.dat, then the money is lost.  A subtle point can be made that since there is then less total money in circulation, everyone's remaining money is worth slightly more, aka "natural deflation".
