| Jun 28, 2020 at 11:02 | comment | added | David Schwartz | @DavidMulder The accepted answer answers the wrong question -- when do you need a blockchain, that is, when do you have a problem that can't be solved without a blockchain. That's not the question the OP asked at all. (When do you need a car in the sense of when can a horse not possibly do the job is not the same question as whether a car is a good solution to some problem.) | |
| Jun 28, 2020 at 11:01 | comment | added | David Schwartz | @DavidMulder As for cost, blockchains are only expensive if they do the initial distribution of a cryptocurrency in a decentralized way. That's still an advantage for blockchains because non-blockchains systems can't do that at all and blockchain systems that don't have that requirement don't have that cost. | |
| Jun 28, 2020 at 10:59 | comment | added | David Schwartz | @DavidMulder The original question pointed out only one supposed disadvantage of blockchains and I showed that it's actually an advantage. You are confused about data mutability -- there is absolutely no difference between "first the data was A, now it's B" and "the data has, as an immutable state, that it was A and then appended on that it changed to B". Mutability and immutability are two ways of expressing precisely the same thing. | |

Just because a solution is better or as good as another in one aspect this does not mean it's "just as good" in general. From engineering cost to the requirement that typically data should be mutable (not to say that one doesn't want log files which use merkle trees/hash trees to allow auditing) the cost of blockchain based solutions is significant. The accepted answer does a splendid job highlighting in which rare cases a blockchain makes sense outside of the 'cryptocurrency' use case it was designed for, whilst this answer barely touches upon one aspect. | |
