Deeds and Titles are typically government issued. For lack of a better word, we can call it a "Bitcoin Account". I've added some different graphics for the elliptic curve crypto and a better background.
Also, since when you import the private key you basically transfer all of the bitcoins in the account, I changed it from "SPEND" to "SPEND ALL".
This design gets better with every iteration. Keep up the good work!
I think "Bitcoin Wallet" is more accurate than "Bitcoin Account". Although an "account" generally implies an ID and password which could be interpreted as public key and private key, in the case of Bitcoin, "Account" is analogous with bank account and/or Bitcoin "Address".
It's not clear (since Bitcoin is unprecedented) but I believe these are the terms we should consider:
1) Bitcoin Wallet
2) Bitcoin Financial Instrument
3) Bitcoin Certificate
4) Bitcoin Bearer Bond
The first two, I feel, are accurate in their own right. A bitcoin wallet is a financial instrument.
I believe an argument could be made for certificate as in "certificate of ownership". The certificate would essentially make you the owner of that bitcoin address but not the owner of any specific amount of BTC.
Similarly, "bearer bond" could be used because whoever is the bearer of that paper has control of that bitcoin address. However, a bearer bond is a debt instrument and bitcoin is not a debt instrument.
Regarding "LOAD & VERIFY" and "SPEND ALL" compared to "ADDRESS" and "PRIVATE KEY". The first set of terms provides some usability for those new to bitcoin it helps them understand what each "number" is for, which is nice :-)
If we look at money from a century ago on Wikipedia we can see that sometimes full sentences appear. We should consider that this type of financial instrument requires instruction to use and re-use and we should consider 1 or 2 URLs be placed on the design, especially bitcoin.org
Also, I wonder what it would look like with a WIF private key instead of mini key.
