That doesn't really need the multiparty aspects of a blockchain though, you can solve that with just cryptography. (Indeed in Germany digital cashier machines etc already need to store such logs and print the transaction checksum etc on receipts - just storing that online instead of on the device is currently not common)
- nforgerit 4y agoI was deliberately talking about a hash-chain and not about blockchain. Point is, if they infrequently collect the head's hash, the tax audit consists of just a recalculation. That could be a first step. If they then would somehow (like you mentioned) provide a service for providing authenticity of receipts, they'd have a system that works better than what they have now with much less work. Am I missing sth?
- detaro 4y agoThat it's not really relevant to discussion of "crypto" in the sense used here, and that this logging already exists and is the law? The checking obviously still needs to be done, and since people generally dont get receipts digitally requires some manual work.
