I think what would be better would be a centralized identifier that is ratified and federated and approved by the federated systems. (This could be a plausible use of blockchain). If they would incorporate that, then you could have the same identity regardless of what decentralized server you were on. Perhaps that would be a useful tool. Federated Centralization. Recreate the utility of FB/ Twitter / Google sign on without giving your data to tech conglomerates. You could even make it so that each site shares a unique sign in key so that you are the only person with the information of the main key and that would make it harder to trace back user info to the defederated central server system.
