Blockchain is made easy with the help of omini basis it is used to run businesses and    professionals  that is large scale and small to feature blockchain application without much cost or challenges ..The ominibasis helps transparency and security and also increases speed omini payment helps for easy payment blockchain can transfer supply chains and it can eliminate costly delays .

concerning the doubt of private handling of the real goods, in regards to how to ensure a barcode on a box of banana's can be messed with in the physical world while a blockchain is just data.

the shipping companies would only get paid if they actually deliver the goods requested. and as such if there was something not quite right about the physical box of banana's that does not match the blockchain data. then the nxt tx that shows the pass over from one depot to the next depot would take the banana's out of the blockchain and treat them as bad batch or stolen goods or defective product.

so keeping a precise inventory of a freight container is not just about data on a blockchain. but also the depots scanning barcodes and quality assurance checking the goods on the container. thus preserving the data represents the real bananas

so for the end destination retailer that is paying for the goods. if he does not get them. he does not pay shipping. so basically the shipping companies would need to stay honourable and follow the rules, else they wont get paid.

thats the whole symbiotic relationship of consensus and blockchain. everyone agree's and checks else if something goes wrong the data is rejected. so its in everyones benefit to play by the rules rather than try messing with your own data thinking they can game the system

its like mining. there is no point a miner(shipping)messing with data of a block or messing with an asset(banana). if the end recipient(retailer) does not accept what is in the block follows the rules. as they can just reject the block. and as such those collating the data and asset(shipping) wont get the reward(payment). thus no point the miner collating data(shipping) mssing with data or assets

...
as for why blockchain.
world wide shipping involves many companies. and this makes it expensive to have a central database with multiple access points where any employee from any company could edit the data. so auditors, security guards, hr departments build up alot of pen-pushing admin staff.. by having it as blockchain you dont need all th staff to monitor access to the data, as the data is self securing by its distributed and community auditing methods of consensus. thus if some pineapple company wanted to mess with banana stocks, they cant. even a banana company cant mess with banana stocks as the shipping and retail community will spot the difference.

..
as for why supply chains
this is to ensure everyone along the line is identified and paid, that way a company getting paid from a retailer cant syphon off the funds and not pay the farmer because its all done in one world wide system where the farmer would get paid and there is nothing a CEO can do you try to put more then he deserves into his own pocket.
its not just about letting a retail customer knowing about where their banana came from. its about the retailer knowing farmers are treated fairly, tax offices knowing the CEO of companies are not hiding profits. customs/borders knowing what tarrifs to charge. farmers proving they sent goods. shipping companies witnessing and signing goods are on route. helping to plan which container gets to go on which cargo ship efficiently. the food standard agency being about to track source if a contaminant/outbreak occured. and many many other things which are normally hand done by admin staff.
