Bigger ships, bigger ports an opening for 3PLs

This story indicates that 3PLs will provide the supply chain wisdom the ocean carriers and port operators  refuse to take on.  Look for more and more profitable intermediaries, rather than fewer, in ocean supply chains. They are not likely to be supplanted by blockchain systems.

Alternative to risky IT investment for maritime firms

Here’s a great idea: why don’t we simply buy a 3PL?  It is a lot easier than developing all that wretched software ourselves!  Seriously, why isn’t consolidation of 3PLs and maritime firms a good way to extend services beyond the port and put them under the control of someone we can trust to (more or less) handle the movements the way we want?   It is a time-honored way to gain capabilities we do not have without doing the work of creating a new business.  Sure there can be some coordination issues, but are they as bad as Maersk has coordinating with IBM on their blockchain system?

Remember that providing coordination and visibility of information is mostly what blockchain accomplishes, and the jury is out on whether it can be made competitive with existing types of databases (which may also need improvement, to be sure).  And any of these systems is “permissioned” in blockchain lingo– there is a governor who is empowered to make decisions about who is allowed to use it.  None of them is truly decentralized for governance, as the Bitcoin advocates would have you believe; in that world, the miners (of whom there are now about 6 with a 75% share of all blocks mined) can exercise control whenever they want.

It comes down to trust. Who do we trust?  Central banks, or a bunch of miners?  Or are we happy enough trusting Maersk, or CMA-CGM and Ceva, or some other 3PL with our cargo, and prefer to argue with them over damaged or misplaced cargoes, rather than debate with some Ethereum sites about these issues?

I’m not sure how it will come out, but I don’t think it will be all one way or the other.

Here is the original article the Loadstar referred me to.  It is a picture a bit too rosy, perhaps, but quite clear.

It doesn’t say that blockchain’s smart contracts will turn logistics people from a handful of paper shufflers to a handful of logicians whose job is to read and prove out the code of smart contracts.  That code will be embedded and executed in a transaction, without oversight, so it had better be right. How do we prove that?  The arguments will shift from arguing about how the actual contract matches with what happens, and goes wrong– to arguing about both that, and whether the smart contract program had a bug in it.

I think there’s a new frontier for provability software, that can read a program and match it with some specs to see if it matches.  The computer mathematicians already have software that can inspect theorem proofs and say if they are valid or not.  I think we need similar software.

Remember every program has bugs. 2018.02.21 07-36-08  Blockchain explained through college basketball — FreightWaves
