So, this is half an idea but I'm going to throw it out there anyway..The problem:
There is a central authority, for postcodes. In the spirit of doing away with the need for central authorities, I wonder then a DAC might be useful.The motivation:
There is value in having consensus.
UK Postcodes alone are valued at £1.8bn a year. See http://www.bbc.co.uk/news/business-26605375
for the recent reaction to learning that UK.gov sold off that postcode detail.The solution?:
As much of an idea as I've had then is to setup a DAC as a reference for addresses - postal addresses and other real world place markers.
Rather perversely, I'm not sure whether this needs a blockchain, as there is no transfer required but instead just a consensus on what the reference is. So, a simple match of the address in a standard format, perhaps is the private key that gives a public unique reference address, which perhaps would be useful for automation and engaging the real world in a standard way. I wonder this almost calls for a reversable key rather than an encrypted one.
I'm struggling then to see how this might be implimented in a way that is easy to reverse, given that normally the move from private key to public address involves a loss of information.
If such a reference can be easily reversed, even if by lookup on the 'blockchain'; and if consensus could be found for such a reference, then 'profit' follows from the savings made from the efficiency such a reference provides.
If it is a lookup service, then populating the data might be a problem; if the public address is easily reversed to the 'private' full address, then no population of a blockchain is needed. This then I wonder is where the idea falls short.. If you need to populate the blockchain then that is tough data to get, if you don't then what is the point?.. and yet consensus is value, so how to secure that value??The reward:
Not for profit but as a loss leader. If there was a good way to make this consensus and do away with central authorities, then perhaps providing such a simple reference service for free would be a useful catalyst for engaging a wide audience for other DACs?
Disclaimer: I'm not a clever man
, so not in a position to implement any of this myself.
