11+# DID PLC Method (did:plc)
2233-DID Placeholder is a self-authenticating [DID](https://www.w3.org/TR/did-core/) which is strongly-consistent, recoverable, and allows for key rotation.
33+DID PLC is a self-authenticating [DID](https://www.w3.org/TR/did-core/) which is strongly-consistent, recoverable, and allows for key rotation.
4455An example DID is: `did:plc:yk4dd2qkboz2yv6tpubpc6co`
66···8899## Motivation
10101111-[Bluesky](https://blueskyweb.xyz/) developed DID Placeholder when designing the [AT Protocol](https://atproto.com) ("atproto") because we were not satisfied with any of the existing DID methods.
1111+[Bluesky](https://blueskyweb.xyz/) developed DID PLC when designing the [AT Protocol](https://atproto.com) ("atproto") because we were not satisfied with any of the existing DID methods.
1212We wanted a strongly consistent, highly available, recoverable, and cryptographically secure method with fast and cheap propagation of updates.
13131414-We titled the method "Placeholder", because we _don't_ want it to stick around forever in its current form. We are actively hoping to replace it with or evolve it into something less centralized - likely a permissioned DID consortium. That being said, we do intend to support `did:plc` in the current form until after any successor is deployed, with a reasonable grace period. We would also provide a migration route to allow continued use of existing `did:plc` identifiers.
