There are lots that have been done to reduce the impact of Sybil attacks on all major DHTs - deterministic node ids, replication, signed payloads, key abuse detection and mitigation, iterative lookups through trusted nodes, etc.
- verdverm 1y agoThose complications are why Bluesky chose something simpler for the PLC that gave them the features they needed given the resources they have available to manage this part of the protocol and infra.
- supermatt 1y agoAgain, and as I said, DHT resolution is just one of many options. As for “the complications”, those “complications” are just software - as implemented in dozens of libs - and already running on hundreds of thousands (if not millions) of nodes on some of the larger DHTs. The “features” they needed were equally solved with did:web using plc.directory - which could absolutely be backed by the PLC transparently.
