1001 Use Cases For Distributed Ledger Technology...

Virtual currencies are so last year. This year is about all the other uses for the underlying technology - the blockchain and other distributed ledgers.  

The number of use-cases is starting to snowball with every discussion about scenarios in which a certain item is dealt with many times by many parties. That's because it will be more efficient and cost-effective for the item to be represented by a 'hash' in the ledger, and each transaction related to that item to be 'hashed' so they are available to any computer running the same language/protocol, rather than dealing with that using 'old' technology. Even though the ledger is openly accessible to everyone's machine, confidentiality can be guaranteed using encryption, so that only those computers with the right private key could unlock the hash and see the details.

Here are a few of the ideas, some of which are definitely being kicked around and most of which involve smart contracts, e.g.:

• car rental;

• identification tools - multi-factor authentication - e.g. checking validity of a drivers licence (hat tip to Alex Batlin)

• issuing/trading shares, bonds and other financial instruments;

• freight, transport, logistics - e.g. booking space in shipping containers, long-haul trucks and aircraft, and keeping track of the delivery items themselves;

• tracking, controlling autonomous vehicles/devices;

• switching to the best tariff minute to minute for services related to cars, homes, devices like insurance, gas, electricity, phone contracts;

• renting hotel rooms, accommodation;

• tracking and paying royalties for music, films etc;

• something I'm working on that it's not my place to disclose;

and on, and on.

In other words, distributed ledgers as a platform will have the same horizontal impact as the Internet,  mobile networks and the smartphone. The ledgers won't necessarily replace any of that, but will be an important layer, enabling all sorts of applications and devices to 'run' off the recorded transactions and related events.

Worth giving is some thought - just keep a good old fashioned pen and paper handy to jot down the flow of ideas ;-)

Christmas Special

Here's a little thought to distract you from the frustration of seemingly insufferable transport delays over the holiday season: might all this grief be a signal to either buy transport companies' shares or short them?

If it's true (as you may bitterly begin to suspect) that transport companies are ultimately profiting from captive UK customers (and the government) by raising fares despite ongoing public subsidy, under-investing in service improvement or snow-clearing and/or saving money by reducing services during difficult weather conditions, then might it not be worthwhile to buy their shares? I mean, if they're engaging in all theses tactics to be more profitable, then why not climb aboard?

Or perhaps you would prefer to bet that, if transport companies are unfairly taking advantage, then sooner or later they'll get rumbled and their stock prices will fall. In which case it may be worth shorting their shares.

In either case, any gains you might make would at least off-set fare increases and other costs. And the consolation that you are personally profiting from disruption might ease your personal discomfort.

Of course, your suspicions may prove to be unfounded or, even if true, may not be material to corporate results or otherwise sound in the market. In which case your investment won't pay off and you're misery may increase. But, hey, at least you'll be able to console yourself that you didn't just sit there simmering helplessly ;-).

Anyhow, safe travels and have a happy Christmas and New Year.
