> HN is very anti-blockchain which is surprising. I’m not agreeing with the twitter user saying Wiki should be on a blockchain but projects like Visa B2B Connect, which wants to use a DTL for interbank transactions, or multi-party supply chains are valid use cases. They’re also technically interesting. The context for the blockchain is distributed public log allowing anyone to replay and revalidate transactions from the inception at any given time with no need for approval of any other parties. As soon as any of those characteristics ( distributed, public, revalidatable) are not met ( !distributed, has access controls, not revalidatable from inception ) it became a weird ass database. Probably a rather lousy database. Visa B2B Connect is a database, which is why Visa is needed and which is why customers need to be onboarded. Blockchain there is a marketing gimmick.
