I don't even understand what an "unmodifiable blockchain" held by a single private entity could mean.
They
- have the data of yesterday
- have backups of the data of yesterday
- are going to write today's data on top of it to continue the chain
(insert magic here)
- somehow we are super sure, tomorrow, that today's data has not been tampered with
If somebody can shine some light on the magic part, I'm interested
- onraglanroad 4mo agoThe point isn't that you can't add bad data: obviously you can. The point is that if the hashes of the blocks are published, you can't later go back and tamper with that data.
