Um, this is not part of the bitcoin block-chain? The bitcoin blockchain started way back in 2009. Nice try? Perhaps this guy is Satoshi Nakamoto? I am confuse

The block chain is always growing. This was recently added to it.

Sure it is. You can verify it yourself. [tsl@pepper ~]$ strings -n 20 ~/.bitcoin/blk0001.dat | tail -3 :TXXXWw,_ "), ,wWT: ::TTXXWWW lXl WWT: ----END TRIBUTE---- [tsl@pepper ~]$ The bitcoin blockchain contains a record of every verified transaction that's happened to date - it needs this information to verify new transactions. Sometime in the last 500 blocks or so, Kaminsky and Goodspeed used a trick to embed this memorial inside a transaction, which is then dutifully stored by all bitcoin clients.

  One wonders how the creators intend to scale a system where every user needs the entire past state of every coin..

    How else are you going to guarantee the irreversibility and proof in such a system? The block chain was very much a careful design consideration. Every user doesn't even need the full set of transactions. I buy and sell bitcoins and have only run the desktop client for a few minutes to see what it looked like.

    See https://en.bitcoin.it/wiki/Scalability https://en.bitcoin.it/wiki/Scalability. It is true that the network would have to evolve to a two-tiered structure with supernodes and client nodes. In Satoshi's paper it is explained how low-power client nodes can do "Simplified Payment Verification" (Section 8 of http://www.bitcoin.org/bitcoin.pdf http://www.bitcoin.org/bitcoin.pdf). This is the mode implemented by bitcoinj (http://code.google.com/p/bitcoinj/ http://code.google.com/p/bitcoinj/) and it is already used to run bitcoin clients on android.
