A Transparent and Verifiable Way to Sync the AT Protocol's PLC Directory
didplc.directory | DID:PLC Read Replica
A DID:PLC read replica for the AT Protocol. Resolve DID documents without hitting the main plc.directory server.
did:plc Directory
PLC is a persistent global identifier system, which allows accounts to retain relationships while changing names or migrating between service providers. It makes use of cryptography and gives individuals (or organizations) direct control and ownership over their identitifier, but does not make use of any blockchain or cryptocurrency technology, and is inexpensive enough to provide as a no-cost service.

Creating an Independent Public Ledger of Credentials (PLC) Directory Organization - AT Protocol
As the next step of maturing governance of the PLC identity system, Bluesky Social PBC is supporting the creation of an independent organization to operate the PLC directory.
built an atproto terminal ui for setting up alternative plc rotation keys. there are two types of keys. hardware-based: no sync software-based: synced via icloud is anyone interested in this? I could package it up and release it, though it needs a lot of UX work. tangled.org/saewitz.com/plc-touch/
Been thinking about plc.directory as a single-point-of-failure So as a learning exercise, I threw together DIDMARC - an example of an independent witness for the directory 🔍 This approach uses Starknet to be fully trustless, but a trusted mirror could perform similar checks to identify abuse
