I would like to purchase BTC's and save the majority of them in a paper wallet as I expect to hang on to them for at least a few years.

I was thinking of doing the following:

1) Install Electrum from a live DVD/USB (Ubuntu or Tails) onto a computer that's not online.

2) Record seed and copy the address's generated.

3) Delete the wallet

4) Send BTC's to the address's that were generated offline.

5) Confirm transfer of BTC's at Blockchain.info.


Does the steps above seem OK? Is there anything that should be changed or added?

How does the blockchain know that the address's that were generated offline are valid?


TIA
