In the last Networking & Communications blog post, chemewordsmith
posited that cryptocurrency--the most well-known of which is bitcoin--is in
some capacity here to stay. News from this week may already be proving this
prognostication correct.
Last month Goldman Sachs filed a
patent application for a new cryptocurrency they're calling "SETLcoin." The
currency is a component of a broader proposed settlement management system
aimed at reducing settlement times for securities transactions, which often
take days due to the financial mire of middlemen and other monetary difficulties.
SETLcoin would use blockchain "general
ledger" technology very similar to bitcoin's.
Based on Goldman's patent application, SETLcoin is a little
more complicated than a typical cryptocurrency. First, a single "coin" has
indefinite value, even in securities. Assuming an example of trading Google
stock, an "unmarked" SETLcoin can be assumed to have a single-share value, in
which case it would be simply termed "1 GOOG-S" [SETLcoins are labeled
according to their ticker symbol accompanied by an "-S"]. But the same label
can be marked as having a plural denomination of the same share; ie. "1 GOOG-S
valued at 100 Google shares" is a single SETLcoin worth 100 Google shares. I
find this needlessly confusing, but on we go.
What's more, SETLcoins can be assigned values corresponding
to a number of different currencies. So, a single IBM-S can be exchanged for a
certain amount of another company's stock or a SETLcoin worth US dollars. They
can also be directly converted into cryptocurrency, so you could trade your
IBM-S for 100 litecoins, or 5 bitcoins, or whatever it's deemed to be worth. In
that case the whole SETL concept is lost in the conversion to cryptocurrency,
if I'm reading the press release correctly.
[Unbeknownst to me before researching this blog post,] there
are hundreds of cryptocurrency types, of which only a handful are notable or
have large ($10 million+) market caps. And while the more decentralized
alternative currencies like bitcoin are starting to gain some clout in the
marketplace, corporate currencies like the one Goldman's proposing don't have
much of a precedent, which seems worrisome. After all, how much do you trust
your bank without the backing and oversight of the Federal Reserve?
But while many are touting SETLcoin as a "cryptocurrency,"
it seems to function more like a Goldman Sachs giftcard. Because a coin only
has value insofar as value is ascribed to it by a seller/buyer/Goldman, I see
this proposed system more like using a debit card instead of a check at the
grocery store: the currency's coming from the same place and you have to trust
a middleman to some degree (Goldman in the case of SETL, or Visa/MasterCard for
debit card services), but it's much more convenient and efficient. And while
it's a little different in principle, a few corporate players have been trying
to get involved in or spur
the "cryptorevolution" for some time now--Goldman's certainly not the first.
It'll be interesting to see if this system comes to pass. A
successful patent application would open up the need for enhanced network and
database security to protect an as yet unregulated and decentralized currency.
I, for one, will be skipping the SETL conversation and continuing to wait my
four business days.
