Does someone know if smart property is already really used now and what are the currently discussed implementations and concepts?
I don't think "smart property" or "smart assets" under our current
understanding and technological level can exist without third parties.
The blockchain was created only to facilitate a currency device that is
itself the blockchain system. That is Bitcoin's secret to success. The
blockchain is not really a currency facilitation platform, but is the
currency. That was the solution that Satoshi created. The blockchain
is not a chained ledger system, but is the digital token represented
in a physical verifiable form with self arbitration rules. Even Ethereum
has fallen into this trap, where they wanted to create a smart contract
platform based on blockchain, yet their token is mainly used for
currency or asset speculation, as a natural consequence of using
the blockchain within their concept. (IMO, it will become more
and more a regulatable currency and less a contracting device.)
So, if you choose to accept that argument, how is it possible to
"blockchain" things which are not actual representations of the
blockchain system, but only representations of things outside that
blockchain?
I'm not saying people are misguided here or are wasting their time,
since someone may come up with a solution eventually/possibly, but
I do not think the answer will be "blockchain". When Satoshi created
the blockchain, it was a means to an end, not a multi-tool solution
that can be added to preexisting systems to improve efficiency or
whatever. He backwards engineered for an online currency solution.
"Smart Contracts" and the like are expected and inevitable into the
future, but I think they will only be possible when non-biased and
non-corruptible Artificial Intelligences will perform the third party
duties that are always required for representations that the
blockchain can not directly represent.
