This is a curious topic to be raised on this curious site for an OP with that name.  Though I wonder if you named yourself ECB just for the provocative value on this site.

I'm still grappling with the technology of the block chain and how it works. (I hope you don't disqualify math as technology.)  And I especially include the cryptographic hash.

But wouldn't someone who calls himself ECB really hate the block chain and see it as competition?
