They did use to use firstbits (not sure if they stopped because firstbits stopped or if they just decided that they didn't like the idea).

firstbits was a centralized concept as the conversion was based on database entries which may be modified leading to trust issues. MinAddress conversion is completely based on blockchain information and in no way the Min-Address can be modified.

Oh - I had thought that firstbits was just an *algo* that was based upon the blockchain also (happy to be corrected if you can show me a link). In any case firstbits doesn't work now so nice to see the idea appear again (now let's see if you can talk blockchain.info into using it).

Isn't this basically just "firstbits" (which seems to have disappeared a while back)?

Well it's not recommended as the best practice but I don't see anything dangerous in doing so. I think it's just a precautionary measure. I'm sure DannyHamilton will now tell me otherwise, though hehe.

Isn't re-using the same address not regarded as questionable?
i.e not the recommended best practice?

It requires you to re-use the address. Other than that is appears to be "safe".

I think something like this would be a great and useful idea, but it would be difficult for me to trust fully without it being proven safe 100% by others. Not saying yours isn't but I'd need to look into it more and have vouches from respected people.

Hi,

MinAddress is condensed form of your address with the following features:
Next generation address which is easy to remember and type
Case insensitive
Permanent and secure
Easy to verify

MinAddress uses the following concept making it permanent, secure and easy to verify:

Full address to Min-Address Conversion:
#Take the full address and find the block in which the first transaction to address occurs.The block number is the converted to hex-code and forms the first part of Min-Address.
#Get all the receiving addresses in the block and do a case insensitive comparison to find the minimum number of initial characters which uniquely identify the address, this forms the second part of the Min-Address.

Min-Address to Full address Conversion:
#Take the First part of the Min-Address and convert it to decimal, this is the block number.
#Get all the receiving addresses in the block and do a case insensitive comparison to find full address which uniquely matches the second part of the Min-Address.

After every conversion you will get a verify link which can be used to verify your Min-Address/Full Address.

Example: Bitcoin Full Address: 17ykeSBpC8MrJr4GrizNUYz6DEnwQ598fQ
             Min-Address: 3fa5b-17yk
             Verify Link: http://blockexplorer.com/block/00000000000000099f086871f03d03f6639b89799cb6d452a9f34c5764f83dcb

IMPORTANT

It seems that many people confuse this with some kind of centralized system where I can later change the Min-Address. To clarify the information is completely based on blockchain and in no way the Min-Address can be modified. Also even if MinAddress.info is down, the user can easily convert the Min-Address to Full-Address. Suppose you have a min address 3fa5b-17yk which you want to convert to full address. Just use any online tool to convert the first part "3fa5b" to decimal from hex which will be 260699. Now go to block 260699 in any bitcoin blockchain like blockexplorer.com and search for "17yk" .You will get your complete address 17ykeSBpC8MrJr4GrizNUYz6DEnwQ598fQ.

Minaddress.info just automates the conversion process[which can be done manually as shown above] and has no control over the final Min-address.

MinAddress Update [14-9-14]:

• Support for formats 17lv:46e02 as well as 46e02-17lv
• Added blockchain.info as backup data source along with blockexplorer.com to provide better service
• Added AddressMap which can be used for quick visual verification of addresses
• One to One Correspondence between MinAddress and Full Address implemented to prevent mistakes in MinAddress
