How does “blockchain” prevent a document from being falsified?
- YeBanKo 4y agoBlockchain allows you to to trace every transaction to its source and prevent double spend, if it is public. It does not have to be decentralized though, can be a closed system where every node has to go through a certification. I assume that a certified mining facility would be closely watched to ensure that the amount of lithium they mine matches what the sign for in transactions. And on the output, battery manufacturers are required only buy lithium they can trace to a certified mine and sign every device the make, including how much lithium it contains. If the ledger is public, anyone can verify that input=output + balance. It is not going to be decentralized, but it can be publicly verifiable.
