but i think it is a terrible idea because humans will make mistakes in calculations all the time and it is a really long and time consuming activity while there are many other safe ways to create a secure address.
Topic: paper and pencil bitcoin (Read 909 times)
I found the wikipedia article to be very helpful. Also check out different forums and read lots of posts to get a good idea of bitcoins, not just the technical stuff but the social things as well.
You can mine Bitcoins with paper and pencils, but Your hash rate will be measured in seconds / hash, not hashes / second. 
If the only things you were allowed were paper and pencil, say you were creating bitcoin in the 15th century, how would you do it? I ask because I'm trying to get a better understanding of how bitcoin works, and i think this would help a lot.

P.S. You can't mine with paper and pencil and you can create address with paper and pencil but it's little hard.
