I work broadly in financial markets. BC was talked into the ground thankfully ending 2018. Haven't heard squat since. I was genuinely interested particularly on aspects of dis-intermediating custody banks. But it doesn't take long to realize a few things about bonafide public BC: - the random guy adding his/her node to the network will need to catch up on serious data amounts or just take somebody's snapshot "as word". Can you boot strap your new node with a snapshot. Should you? Well, what are you going to do about getting all the back data in? - nobody is going to put private financial/trading/whatever details plain text on a block. so it'll have to be encrypted. so what are we really verifying? you're verifying what my copy of PGP produces? whatever gibberish I post to the block? I don't want to disclose from/who/when/amount/shares/bank-info/exchange/stock symbols .... nothing ... but regulators may need to see data un-encrypted ... so now what? Send regulators data the old way? While I do CAPEX the new way? C'mon. - The data has to be represented somehow. Since BC brings nothing to that party ... BC will wrap Swift, FIX, Omego, or by exchange or by regulator reporting format ... so BC is a crap load of work to fix nothing about the domain. And even that is a simplification. There's lots of little gotach's in data reporting between all the counter parties. - throughput is an issue on BC - just the idea that any joe can add a box to the network and start looking at financial data ... it's a non-starter ... although we can argue you can get some visibility from exchange data ... but traders might use BC to help settle and that may require a heck of a lot more detail that what NASDAQ provides - BC isn't a currency. A currency has to do certain things including being universally accepted in the country, have near constant value day to day. Whatever that is BC doesn't do it. - Another thing I find jaw dropping about the BC mentality is the insistence the unshakable foundation of the blockchain insofar as its non-deprecation and on the computers to apply the same logic and/or verification and xfer fees without human interference or bias. To date BC is pre-pre-pre-neophyte status. You start bringing in serious economic pressures, 1-offs, crashes, bailouts, disagreements and I'll bet some or all that code will fail/falter in human hands leading to code changes leading to forking. Today's money system didn't start this way. It was beat into today's shapes through problems, mistakes, and here and there some good ideas. So will BC. I seriously doubt the immutability of the rules governing blocks. Now you can back off public, decentralized ... into private block chains with shared or not shared keys and the like ... or just point-to-point block chains between trusted and distinguished entities ... but very quickly ... so what are we really doing here? BC is used it seems to me for speculation, buying small potato things like coffee or for the coolness factor or hiding. I'm not seeing serious industrial use cases. Now, there are two areas that I might see BC useful for: - things like ownership, proof of (say houses) - maybe voting -
