@5b00f2ed *Sigh* the block chain is even the interesting component of a failure of an experiment 

It's not an accident it's not named blockcoin

It has essentially a single use case, and arguably none w/o a sensible consensus protocol which has yet to be proposed b/c all current proposals don't accomplish stated goals

If there is magic in cryptocurrency its so obviously asymmetric cryptography+merkle tree. 

Hence the  name Bitcoin, as in BitTorrent b/c the common use of merkle tree
