Blockchain Equally A Platform For Render Chain

I went to a Supply Chain Management on Blockchain panel number at Marquette University end night. The recording of the session is available. It was on the topic of using Blockchain to create out provenance of supplies throughout the Supply Chain. This was on the full general topic of render chain, non specific to healthcare, or the most specific instance of drug components inwards healthcare. However the full general concept of render chain occupation of blockchain is straight transferable into drug supply. I mightiness struggle that drug render chain probable has to a greater extent than chance to receive got payoff of blockchain, in addition to to a greater extent than coin available to fund that sort of enquiry leading to an implementation.

Blockchain, keeps fidgeters occupied, non bothering others

The verbalize was mostly close the full general concept, full general need, in addition to by in addition to large how blockchain would help. Nothing shocking, but it is useful to withdraw heed it from people who receive got done it. The panelists were Dr Mark Cotteleer from Deloitte, Chris Kirchner of Slync, in addition to Paul Biwer from Biwer & Associates. The invitee speakers were from organizations involved inwards actual occupation (pilot) inwards the Food supply-chain, in addition to inwards parcel shipping.

The kickoff caution was that the larger the network of render chain participants, the to a greater extent than complex; the to a greater extent than complex the harder to brand a working system. Hence the rattling narrow usecase focus inwards the parcel transportation usecase to runway packages given into their control. In this instance the speaker indicated in that place were close v participants, so I am guessing these would last a few out-sourced carry or handlers.

What information should teach into Blockchain vs managed classically?

I spoke to them afterwards. Given that they receive got experience, I asked if whatever patterns receive got emerged every bit to what information genuinely goes into the blockchain, vs what information is managed inwards classic ways. Looking for patterns from experience. I got a rattling rigid answer: "As picayune every bit you lot tin teach away alongside goes into the blockchain". One argue given was that the to a greater extent than you lot seat there, the to a greater extent than frail the scheme is to improvements. Once information is inwards the blockchain, it is in that place forever. It is far easier to after add together an chemical element of information that wasn't previously shared. But i time something is in that place it is permanently there.

Permissioned blockchains

They are both using Permissioned chains, where a pocket-sized subset are authorized to add together to the chain, in addition to where a subset of them receive got validation in addition to counter-signature responsibilities. The validation requirements are use-case specific, in addition to information accessibility specific. Where picayune information is on the chain, picayune tin last validated. Where that information approaches nothing, the alone validation is the date/time postage stamp freezing that information inwards time. So clearly in that place is a balancing line of putting plenty into the chain to brand validation valuable, but non so much every bit to brand the solution frail or dangerous.

Danger of populace accessibility

I in addition to then approached the topic of negatives. That is to say, the blockchain use-case volition piece of work fantastically when everything is running smoothly in addition to everyone does their duty properly; but the argue a blockchain is used is because at approximately dot somebody volition skid upwards in addition to something bad volition happen. It is at this dot that the blockchain is used to create upwards one's heed from something bad happening, dorsum to who caused that bad thing. Without this need, in that place is no demand for blockchain. So, it yesteryear Definition volition happen.

IF this investigation is done inwards public, the participants volition all teach rattling nervous, mayhap deciding to goal participating. I dot out that the FDA does these kinds of investigations, in addition to 'almost always' does them inwards secret. This because the bad histrion unremarkably has made a mistake, in addition to non done something malicious. H5N1 punishment from the FDA gets them to modify their ways, without scaring everyone. Or scaring the whole public. The FDA choses approximately cases to brand public, unremarkably due to malicious intent, or to 'make an example' out of a large player. With blockchain, peculiarly populace accessible, everyone tin practice the homework to create upwards one's heed who the bad actor; so it volition last rattling publicly known… in addition to all the proficient actors volition start to query if they should participate, every bit everyone knows that they volition slipup at approximately point…

The respond I got was… hmmm, never idea of that…

The large Aha moment

In the discussions I got an insight that for approximately argue had escaped me till that point... For whatever specific use-case, similar Supply Chain Management, i does non necessarily receive got but i chain. I had been thinking that all of the blockchain features that the use-case would practice goodness from should / would last provided yesteryear i blockchain. But this is non necessarily the best approach. The specifics were that i demand is to runway the time period of supplies, where approximately other demand is to know that in that place is a confirmed demand for that specific supply. These interact inwards that the render should non last shipped without a confirmed buy of that supply. But both functions don't demand to last on the same blockchain. There are actors that should receive got access to the time period of supplies, in addition to they are slightly overlapping Venn diagrams alongside those that should receive got access to the confirmed buy facts. Only a few of these actors belong inwards both camps, most are not.

I intend inwards the healthcare use-case of using Supply-Chain Management specifically of drug components probable has similar needs/functionalities that would practice goodness from Blockchain, but are exclusive audiences.

Some actors mightiness last inwards the Privileged grouping for tracking movement, but alone readers of the other use-cases. Some mightiness non receive got whatever visibility into the buy chains...   

Simple concept i time it is set out... 

Summary

1. Start alongside a use-case that has fewest actors to move on it every bit uncomplicated every bit possible. You tin ever add together actors later.
2. Design each blockchain to grip the correct audience in addition to active participants. You tin ever add together to a greater extent than functional chains later.
3. Put every bit minimal information into the blockchain every bit you lot tin teach away alongside for the use-case need. You tin ever add together to a greater extent than information elements when they are constitute to last critical.
4. Augment blockchain functionality alongside classic information management methods. Don't abuse the blockchain, occupation it carefully.
5. Think through abuse scenarios upwards front. Happy-path is nice, but non why you lot are designing to occupation blockchain.
