Satoshi Reply to Mike Hearn

April 18, 2009 by bitcoincash

From: Satoshi Nakamoto <satoshin@gmx.com>
Date: Sat, Apr 18, 2009 at 6:16 PM
To: Mike Hearn <mike@plan99.net>

I sent back 32.51 and 50.00.

I badly wanted to find some way to include a comment with indirect transfers, but there just wasn’t a way to do it. Bitcoin uses EC-DSA, which was essential for making the block chain compact enough to be practical with today’s technology because its signatures are an order of magnitude smaller than RSA. But EC-DSA can’t encrypt messages like RSA, it can only be used to verify signatures.
