First step to use block chain
I think an easy start to leverage it is within your own company. A blockchain can provide transparency on the value creation flow from raw material through production to customer sales. It is very valuable to understand the time the steps took and the cost that was added. That does not require all the mumbo-jumbo of cryptocurrency, nor are you depending on other companies to join and be part of the chain. Without them a global chain just will not work :(
Do a small POC within the organization among your small set of suppliers, OE for a product or RM provenance.
And if possible do a smart contract POC as well.
eg. you have 4 entities, one Plant, One Supplier, One Logistics partner and one customer.
For a customized product, your customer puts a request ( you have to identify which attributes you have to capture in the customer UI page)...the same request with those attributes along with time stamp is registered on the blockchain.
The information is viewable by all 4 parties.
As soon customer enters the details, you put additional inputs (page to view and add info will be based on your access rights)
Supplier sees those, add some more stuff as per his UI etc.
Logistics provides views and goes ahead and delivers the product at customer site.
You can see the entire history and make payments by implementing smart contract.
I typed in hurry, if you have further question- feel free to ask.
So many blockchain applications for marketing; who would have thought when the financial markets only talk about digital currencies.
Digital currencies focus on speculation. What would be of more use in sustainability terms is to apply digital ledger technology (DLT) and explore the transactional nature of sustainability accounting and the potential of using smart contracts and encryption keys to develop a structured ledger from the distributed ledger. Not simple, not straightforward but potential revolutionary.
