okay i'm edmund edgar around reality
keys I'm going to keep this short to
leave some room for am Thomas's going to
show you something crazy cool in the
same day using TLS notary so we're an
Oracle Service we've been running since
early 2014 we we started off providing
keys that you could use to make smart
contracts with Bitcoin now so we can
doing that for a while obviously there
were a lot of limitations making smart
contracts with Bitcoin so now we've
started publishing some data that you
can use with ethir iam which is going to
have as we all know a lot more
possibilities our process is very simple
we pull through an API we publish what
we see if that API was correct you can
just leave that as it is and we'll
provide you that late for free if that
information was incorrect you can send
us a dispute Lee and we'll check it out
and what that allows us to do is to pull
from some fairly unreliable data sources
so we can use data for example use data
in the past from freebase or from wiki
data which are things that people can
tamper with but ultimately if you pay a
fee we can check it out with you can get
you to the right answer we found with
Bitcoin we found people coming up with
all kinds of crazy data that they're
interested in that they want to make
smart contact about that we weren't
expecting we found that people wanted to
make smart contracts with their future
selves say if I do this run i'm going to
get my money back if i fail to do the
run my money's going to charity we found
all kinds of things that people want to
do so if there's some data you need you
need it certified so that you can make
trusted contact contract based on it and
you don't see it on the site then just
let us know right now what we're doing
is we're doing the whole thing off chain
so we sign data we give you some data
and a signature you can make a new
theory and contract
just checks that signature and then uses
the data it's not particularly hard for
us if people need it to do it kind of
the traditional ethir Ian way
traditional way of just publishing a fee
and to the chain we can do that as well
so just let us know so that's reality
keys com I know there are your hearing
from Thomas next who also runs a an
Oracle Service and I think it'll be
another one coming fairly soon so it
shouldn't be long until there is
something I at least three independent
trusted sources of data in the market so
you can combine those you can say if you
don't want to trust one of us you'll be
able to say two out of three of these
have to give you know this particular
answer and there are also people talking
if you look up for example Martin from
consensus piece on the ultimate Oracle
there are also some ideas about putting
a proof of state voting system above the
Oracle system so first of all you get
these islands on answer from the Oracle
it's very quick and very cheap but then
if somebody doesn't trust the Oracle or
if somebody thinks they're wrong then
you can throw it to to a vote if you
think that you've got a situation where
you can get a more reliable result from
a proof of state voting system so
they're all kinds of things you can do
with this if you don't see what you need
then get in touch and I hope you can
have a play around with it and see what
you can do with it ok so that's reality
he's calm
you
