Re: [Hyperledger Indy] Hyperledger Indy and Ethereum DIDs interoperability through decentralized universal resolvers on Ethereum/Indy - Nathan Aw from Singapore

Hi Oliver, Markus,

Many thanks. I took a deep look at the universal resolver and its
specifications at https://uniresolver.io/. It is really great. Some
questions I have.

1. Like a DNS system, is there some way that one can contribute to make the
universal resolver a decentralized one? (Based on my limited understanding,
the universal resolver is currently centralized.)
2. If an attacker gets hold of one's DID, e.g.,
did:sov:WRfXPg8dantKVubE3HX8pw, he or she gets all the DID document and its
service endpoint and some public key -- is this potentially troubling?

Thanks !

Regards,

Nathan Aw
