[Bitcoin-development] Reusable addresses

[Byte Coin]

I'm very pleased that my old idea is getting some traction and that I have been 
appropriately credited!
I also think the term reusable addresses is preferable to anything to do with 
stealth for the reasons mentioned.

You should note that the privacy guarantees they provide are not that strong 
but their limitations have been adequately discussed elsewhere.

On an unrelated note - I'd like to solicit some help in restoring access to my 
Bytecoin account on http://bitcointalk.org/

Cheers!

Re: [Bitcoin-development] address collision and undependability

From https://bitcointalk.org/index.php?topic=20955.msg264038#msg264038

This may be an appropriate thread to mention that the the checksum at the end 
of an address does not effectively prevent single character errors or 
transpositions.

For instance https://blockexplorer.com/search/1ByteCoin  shows that

1ByteCoinAddressesMatch1kpCWNXmHKW 1ByteCoinAddressesMatch1kpCxNXmHKW 
are both valid addresses even though they only differ by one character.

Similarly, the valid addresses

1ByteCoinAddressesMatchcNN781jjwLY 1ByteCoinAddressesMatchcNN718jjwLY 
only differ by one transposition.

Subject: [Bitcoin-development] address collision and undependability

There was a discussion on #bitcon-dev yesterday
I stated that it would be impractical to generate two bitcoin addresses, such 
that they differed in exactly one character (modulo different checksums).
The corollary to this is that if you find an address with a verifiable 
signature. Changing one character of that address would have no known private 
key, and hence be normally undependable.
Does that sound correct?
