I've read many of these "The NYSE is using bitcoin!" articles and I'm still not sure if the banks are using the wrong words, or if the journalist are? Maybe I'm missing something? One of the most critical parts of the Bitcoin network is the number of competing (non-colluding) parties doing proof of work. Re-writing the ledge would be entirely possible (and possibly easy) if there were only one or two parties processing transactions. If its just the NYSE "using Bitcoin technology" then haven't they effectively encoded transactions into a linked-list with a few frivolous hashes placed throughout? You need a lot of competing minors to produce the trusted ledger the global Bitcoin network enjoys. If these banks are serious about using Bitcoin (or at least what I define as Bitcoin) then how do they plan on incentivizing a diverse set of non-colluding minors?
