WTF ... SAME PERSON?
Yes, apparently also Mark Zuckerberg, Mark Shuttleworth, The Mark of the Beast, Satoshi Nakamoto, the love child of Stephen Hawking and Tim Berners-Lee, and a secret Nazi here to do economic war or the world.
Similarly, you are obviously from Microsoft, twice, since you are BING BING.
We were having another useful on-topic discussion.
Could marking be used by on-line sellers to make prudent credit-worthiness decisions ? If a seller can decide that a buyer is credit-worthy, then an online transaction can go much faster (i.e., no waiting for block chain confirmations).
A seller can of course themselves maintain a database of clients, and if a client has paid with a crypto currency before, and the transactions have been validated, then the seller can choose to close a transaction online immediately, even before a single block chain validation has occurred, equalling or surpassing the speed at which an online transaction paid with via a legacy credit card can be done.
Can marking be used to make this credit-worthiness decision by sellers who have no previous interaction history with a buyer ?
I see no reason why not, marking together with identifi optionally
[1] expose a provable graph of reputation+trust (and former transactions) which could be leveraged to do this,
The same trust combined with public key cryptography and web hooks can be used to allow instant transactions between implementations. It's very early days but we have the following trello card open.
Marking transactions already have hmac computed signatures on them from the core fields, if implementations had known signing keys they could web-hook post transfers to each other in real time, and settle out of band at end of day.
This is a way for implementations to talk to each other, so they can do transfers off chain and settle the difference between all tx at the end of the day on chain.
[1] Markings are from persona to persona, pseudonymous and off chain, as anonymous as most solutions get. Users can optionally say "I am persona-x on domain1 and persona-y on domain2", this exposes a graph of reputation/trust per domain, reputation with a purpose within some subject domain. This is what we mean by optionally.
