Dumb this down for me, because it's unclear how blockchain would solve the issues you bring up.

Blockchain is just a ledger. So "the Blockchain" does not make anything significantly better. Its in fact ridiculously expensive. The idea is that everytime sweat shop X finishes sewing sequins on a dress, they can scan the RFID tag on the dress with their smartphone, and the ledger gets updated, and then Walmart can prepare for that dress, the shipping company can print out labels etc. Its a good idea. Industries are supposed to work this out, create their own cheaper blockchains that just need some sort of simple KYC to get started, then its as cheap as email to add your little bit to the supply chain. I dont know of any successful implementations Edit: no blockchain will solve the grey market problems. Everything will have to be made genuninely on the chain. Which starts to lead to probelsm with if you cannot get permission to write to the chain ... etc etc

  I appreciate the response, but it's still entirely unclear how blockchain would help here. In a supply chain, why would blockchain be better than a centralized process? It seems to be trying to put a square peg in a round hole.

    It's a fine question - I guess politics mostly 1. If the central database is proprietary then it is enforced (usually by a major retailer ie Walmart drives all sorts of RFID supply chain requirements for its suppliers. If blockchains come in this is likely how) 1.a. But which other retailer will sign up to walmart's versions ? So it is hard for all suppliers to sign up to the same standards 2. Open standards make it easier for anyone to write apps to join the chain. 3. it's not at all clear how this is better I will admit beyond "decentralised" and "open". But those are excellent places to start.

    Tampering. Bribes, hacking, idiocy, whatever. A proper blockchain is tamper resistant, so everyone trusts it.

      I will bribe people to put wrong information on the blockchain then.

        I understand your point, nothing is perfect, but surely a public easily-audited blockchain does more to deter corruption and, if it occurs, find the perpetrators? As compared to a traditional system which is basically a log file that anyone with access (such as a rogue IT admin) can change? You can sign entries but unless you have each subsequent entry build on what came before like in a blockchain, entries can be removed entirely and no one will know. There is a reason companies like DHL are interested in such things. https://www.dhl.com/au-en/home/insights-and-innovation/insights/blockchain.html https://www.dhl.com/au-en/home/insights-and-innovation/insig... Example: Our product is sourced from a company and this providence is on the blockchain. It comes to light they employ slave labour and we'd rather cover it up. How do we alter these original transactions without the evidence being in plain sight?
