# awesome-decentralized-id —Draft

Much appreciation to [Peacekeeper](https://github.com/peacekeeper) for maintaining the [blockchain-identity](https://github.com/peacekeeper/blockchain-identity) repository, to which this document is indebted. 

**Collaboration Welcome**

This is a skeleton, around which I will fill in some background information; highlight the chosen resources; rearrange things a bit, and provide some justification for the way it's organized.

Please let me know if you think any of these resources are just as well left out, or any that you'd like to see included.

## Awesome Self-Sovereign Identity, Decentralized-ID, and Blockchain-ID related resources

>Imagine a world where you are in direct control of your personal information; a world where you can limit and control how much information you share while retaining the ability to transact in the world. This is self-sovereign identity, and it is already here. Blockchain is the underlying technology paving the path to self-sovereign identity through decentralized networks. It ensures privacy and trust, where transactions are secure, authenticated and verifiable and endorsed by relevant, permissioned participants,'—[Jerry Cuomo - IBM](https://techcrunch.com/2017/09/10/the-promise-of-managing-identity-on-the-blockchain/)

### RWoT
"The Web of Trust is a buzzword for a new model of decentralized self-sovereign identity. It’s a phrase that dates back almost twenty-five years, the classic definition derives from PGP.\n\nBut some use it as a term to include self-sovereign identity authentication & verification, certificate validation, and reputation assessment, while the vibrant blockchain community is also drawing new attention to the concept we aim to reboot it."
