> if you want your distributed database to generate unique identifiers, partition the id space so each node is guaranteed not to overlap. You trust to nodes so you don’t need blockchain. You can also generate unique IDs by giving each server/node a unique hash and then use (node_id,1), (node_id,2), ... etc. Its more complex this way but this approach compresses way better if you have a lot of IDs. (Thanks Martin Kleppmann for this trick) |
