* [Mastering Decentralized Identity](https://blockworks.co/news/what-is-decentralized-identity) 2023-03-14 Blockworks
> 1. The current centralized identity system confines the personal and professional development of users to a set of rules and incentives that exploit their attention.
> 2. Many major players are invested in a solution, including Disco, SpruceID, Iden3, Polygon ID, Ceramic, the Ethereum Foundation and many more.
> 3. The global decentralized identity market value is estimated to reach $6.8 billion by 2027 – according to Markets and Markets
> 4. Updates in account abstractions and identity wallets have unlocked new possibilities that have yet to be realized.
* [Decentralized identity](https://ethereum.org/en/decentralized-identity/) Ethereum.org
> traditional identity management systems have long relied on centralized intermediaries who issue, hold, and control your identifiers and attestations. This means you cannot control your identity-related information or decide who has access to personally identifiable information (PII) and how much access these parties have.
>
> To solve these problems, we have decentralized identity systems built on public blockchains like Ethereum. Decentralized identity allows individuals to manage their identity-related information. With decentralized identity solutions, you can create identifiers and claim and hold your attestations without relying on central authorities, like service providers or governments.

## ERC-EIP
### ERC-EIP
Identity related ERC-EIP
* [ERC: Lightweight Identity #1056](https://github.com/ethereum/EIPs/issues/1056)
> This ERC describes a standard for creating and updating identities with a limited use of blockchain resources. An identity can have an unlimited number of delegates and attributes associated with it. Identity creation is as simple as creating a regular key pair ethereum account, which means that it's fee (no gas costs) and all ethereum accounts are valid identities. Furthermore this ERC is fully DID compliant.
* [ERC1056 ❤ ERC780 — an open identity and claims protocol for Ethereum](https://medium.com/uport/erc1056-erc780-an-open-identity-and-claims-protocol-for-ethereum-aef7207bc744)

* [ERC-1812: Ethereum Verifiable Claims](https://eips.ethereum.org/EIPS/eip-1812) 2019-03-03 Ethereum
> A new method for Off-Chain Verifiable Claims built on EIP-712. These Claims can be issued by any user with a EIP 712 compatible web3 provider. Claims can be stored off chain and verified on-chain by Solidity Smart Contracts, State Channel Implementations or off-chain libraries.
* [EIP-712: Typed structured data hashing and signing](https://eips.ethereum.org/EIPS/eip-712) 2018-09-26 Ethereum
> This EIP aims to improve the usability of off-chain message signing for use on-chain. We are seeing growing adoption of off-chain message signing as it saves gas and reduces the number of transactions on the blockchain. Currently signed messages are an opaque hex string displayed to the user with little context about the items that make up the message.
* [ERC-1078: Universal login / signup using ENS subdomains](https://eips.ethereum.org/EIPS/eip-1078) 2018-05-04
> This presents a method to replace the usual signup/login design pattern with a minimal ethereum native scheme, that doesn’t require passwords, backing up private keys nor typing seed phrases.
* [ERC-1077 and ERC-1078: The magic of executable signed messages](https://ethereum-magicians.org/t/erc-1077-and-erc-1078-the-magic-of-executable-signed-messages-to-login-and-do-actions/351)

## Protocols
### Element
### Sidetree \ Element
* [Introducing Element](https://medium.com/transmute-techtalk/introducing-element-328b4260e757)
* [Sidetree Spec V1.0.0](https://identity.foundation/sidetree/spec/) 2023-05-05 DIF
> Sidetree is a protocol for creating scalable Decentralized Identifier networks that can run atop any existing decentralized anchoring system (e.g. Bitcoin, Ethereum, distributed ledgers, witness-based approaches) and be as open, public, and permissionless as the underlying anchoring systems they utilize. The protocol allows users to create globally unique, user-controlled identifiers and manage their associated PKI metadata, all without the need for centralized authorities or trusted third parties.
* [Sidetree Core Protocol and DID Method Drivers](https://github.com/transmute-industries/sidetree.js) 2022-09-20 Transmute
> Sidetree.js is a simple-as-possible TypeScript implementation of the Sidetree version 1.0 protocol. The purpose of the Sidetree protocol is to create a blockchain based public key infrastructure, where rather than having a central authority that can accept or revoke keys, by having the blockchain act as a whitness for regestering public keys, anyone can publish a public key that can be used to establish identity.
* [Introducing Element](https://medium.com/transmute-techtalk/introducing-element-328b4260e757) 2019-05-11 Transmute
> Transmute is excited to announce Element, an implementation of the Sidetree Protocol on top of Ethereum and IPFS. This work was done in collaboration with Microsoft and Consensys under the Decentralized Identity Foundation (DIF)
> ...
> We’re excited to use the serviceEndpoints defined in Element DID documents to track external integrations, in a privacy preserving manner, including identity hubs, credential stores, and more. Furthermore, the scalability that Sidetree brings to DIDs is unprecedented.
* [Element DID Method: Sidetree, Ethereum, IFPS](https://ssimeetup.org/element-did-method-sidetree-ethereum-ipfs-orie-steele-webinar-31/) 2019-07-04 Orie Steele
> In this talk, Orie will discuss the history of the Element DID Method, how it leverages the same Sidetree Protocol that is used by ION on the Bitcoin Network. He’ll introduce the motivation for Element and ION, and then walk through the core components of developing a working DID System, including topics such as wallets, signing, DID resolution, key revocation, and decentralization.

excerpt: "In your application, you must first configure your uPort object with an identifier and a private key (or signer function). There are several ways to instantiate a credentials object. The most common approach is to save a DID and private key on a server for your application and create a credentials instance from your application's unique private key. Signed JWTs for requests and verifications can then be passed to a client-side application, and presented to a user using a QR code or via another transport."

Performant and modular APIs for Verifiable Data and SSI. Create and manage decentralized identifiers + verifiable credentials without worrying about interop and vendor lock-in.
* [Introduction to Veramo](https://veramo.io/docs/basics/introduction) Veramo Docs
> Veramo is a JavaScript framework that makes it easy for anyone to use cryptographically verifiable data in their applications. It was designed to make it easy for developers who want to use DIDs, verifiable credentials, and data-centric protocols to bring next-generation features to their users.
* [How we built Cheqd with Veramo](https://medium.com/veramo/how-we-built-cheqd-built-with-veramo-eb59dd793764) 2023-04-14 Veramo
> Hi, my name is Ankur Banerjee. I’m the CTO and co-founder at cheqd, which is a Decentralized Identity startup. I’ll go into some of the USPS that we are trying to build out, which we are personally quite excited about, and doing that on Veramo SDK as one of the supported SDKs. My journey into digital identity and SSI probably started about five to six years ago. At the time, I was working at a large consultancy called Accenture, and I originally started off working on digital ID for traditional digital identity or traditional enterprises. I worked on a lot of biometrics and ID checking systems for some of the world’s largest banks.

> DIDs are not a replacement for Ethereum Accounts and ENS. Instead, DIDs can be seen as an abstract representation of those which makes it easier for developers to build applications across different chains and platforms. Many developers in the Decentralized Identity Community are already building a lot of Open Source tooling/products and protocols facilitating trust, privacy, security and data sovereignty, to integrate with the Ethereum ecosystem and vice versa. Some of the Open Source components include decentralized agents (e.g. Veramo), secure communication (i.e. DIDComm Messaging), capabilities-based authorization and delegation frameworks (e.g. ZCaps), login w/ identity wallets (i.e. SIOPv2), user-controlled confidential (e.g. Kepler) or public storage (e.g. Ceramic) and more.
* [DIDComm Messaging through libp2p](https://medium.com/uport/didcomm-messaging-through-libp2p-cffe0f06a062) 2021-11-30 uPort
> With InterPlanetary File System (IPFS) the Web3 community has established a critical piece of infrastructure that is used by the majority of web3 protocols to different degrees. Libp2p is part of the IPFS stack and is used for the underlying peer-to-peer network for discovery, routing and data exchange. Peers in the network can dial other peers in the network to exchange messages using various transports, like QUIC, TCP, WebSocket, and Bluetooth. Modular design of the libp2p framework enables it to build drivers for other transports. Peers can run on any device, as a cloud service, mobile application or in the browser and talk to each other as long as they are connected through the same libp2p network.
* [Introducing Veramo](https://medium.com/uport/introducing-veramo-5a960bf2a5fe) 2021-06-18 uPort
> In our last post we briefly presented Veramo and how it evolved from the challenges faced with uPort’s libraries. In this next series of articles we will give Veramo a proper introduction and answer some of the basics: why it exists and what it does, followed by articles describing the architecture in more detail, and how to build applications using Veramo. While our name may have changed, the original vision of allowing individuals and organizations to own their own data and maintain privacy, has not.
* [Veramo: uPort’s Open Source Evolution](https://medium.com/uport/veramo-uports-open-source-evolution-d85fa463db1f) 2020-05-04 uPort
> Over time the technical limitations with on-chain identities began to pile up, which led to uPort’s 1.0 architecture and pioneering the use of decentralized identifiers (DIDs) with our open-source libraries. At the time DIDs, together with verifiable credentials (VCs) were proposed W3C standards and are now nearing official status. Dozens of projects are still using several of our popular libraries: uport-connect, uport-credentials, uport-mobile, did-jwt, and did-resolver, to name a few. [...]
>
> Earlier this year, we released the culmination of these efforts, informed by years of open-source work, learning, and iteration, as Veramo.

> By resolving a DID a validator can typically discover the authoritative keys for different purposes or more generally, a set of verification methods for that DID. An Ethereum account could be a verification method as well. Service endpoints are extensible by design, so you could define your own ones if needed. However, the DID community has agreed on a set of well known service endpoints. Amongst them, the DIDComm service endpoint solves the how-to-reach-me problem and can be used to establish a secure communication channel with the other party. Despite there are only a few limitations of what properties can be associated with a DID, privacy regulations such as GDPR need to be considered very carefully.

## Literature
* [A First Look at Identity Management Schemes on the Blockchain](https://arxiv.org/pdf/1801.03294.pdf) IEEE 2018
> A uPort identity is underpinned by the interactions between Ethereum smart contracts: bespoke code that can regulate the movement of data and ether (the native cryptocur- rency) on Ethereum. Smart contracts are uniquely addressed by 160-bit hexadecimal identifiers, and, when invoked are executed by the Ethereum Virtual Machine (EVM) installed on every Ethereum node. Two smart contract templates designed by uPort comprise each uPort identity: controller and proxy. To create a new identity, a user’s uPort mobile application creates a new asymmetric key pair and sends a transaction to Ethereum that creates an instantiation of a controller that contains a reference to the newly created public key. Then, a new proxy is created that contains a reference to the address of the just-created controller contract; only the controller contract can invoke functions of the proxy; a constraint that is specified in the controller and enforced by the EVM. The address of the proxy comprises the unique uPort identifier (uPortID) of a user. A user is free to create multiple uPortIDs that are unlinkable. Figure 1 provides an overview of an interaction between a uPortID and the smart contract of a decentralised application on Ethereum.
>
> The private key that controls a uPortID is stored only on the user’s mobile device. Therefore, an important aspect of uPort relates to its social recovery protocol for the event of loss or theft of the user’s mobile device. For that, users must nominate the uPortIDs of trustees who can vote to replace the public key referenced in the controller with one proposed by the user in need; once a quorum is reached between those trustees on the new public key, the controller replaces the lost public key with the newly pro- posed public key. This process enables the user to maintain a persistent uPortID even after the loss of cryptographic keys.
>
> A final aspect of the uPort scheme is its support for securely mapping identity attrib- utes to a particular uPortID. The uPort registry is a smart contract that stores the global mapping of uPortIDs to identity attributes. Any entity can query the registry, however, only the owner of a specific uPortID can modify its respective attributes. Due to the inefficiency of storing large volumes of data in a smart contract, only the hash of the JSON attribute structure is stored in the registry.

* [WEB2 VS WEB3](https://ethereum.org/en/developers/docs/web2-vs-web3/) 2022-09-27 Ethereum
> Web2 refers to the version of the internet most of us know today. An internet dominated by companies that provide services in exchange for your personal data. Web3, in the context of Ethereum, refers to decentralized apps that run on the blockchain. These are apps that allow anyone to participate without monetising their personal data.

> As Jeremiah pointed out when we bumped into each other last night, public discussion of “web3” is almost completely focused on this last item: tokens, and the many ill-begotten schemes that they have enabled.
>
> But that is not web3’s lasting attraction. The other four promises – participation in governance, self-sovereign identity, content ownership and the freedom to build – are very appealing. In fact, it is hard to see how anybody (other than an incumbent with a turf to defend) could possible argue against any of them.

> Certainly, there is a wide range of opinion on Web 3.0: Cutler mentioned how Elon Musk sees this is more marketing hype than reality. Notably, there is a lot of money being pouring into Web 3.0 — Cutler said, “Venture capitalists have invested $12.75B in 460 different blockchain projects this past year, up from $2.75B in investments during 2020”. Widman said that “With Web 3.0, you have to get to a marketplace of ideas where they can win on their merits,” before the concept will gain traction.

With such augmented sociality, web3 can eschew today’s hyper-financialization in favor of a more transformative, pluralist future of increasing returns across social distance.

> what gives Aggregators their power is not their control of supply: they are not the only way to find websites, or to post your opinions online; rather, it is their control of demand. People are used to Google, or it is the default, so sites and advertisers don’t want to spend their time and money on alternatives; people want other people to see what they have to say, so they don’t want to risk writing a blog that no one reads, or spending time on a social network that because it lacks the network has no sense of social.
* [Web3 and Digital Embodiment](https://www.windley.com/archives/2022/01/web3_and_digital_embodiment.shtml) 2022-01 Phil Windley
> Web3 will make a difference for all of us if it enables people to become digitally embodied, able to recognize, remember, and react to other people and organizations online—without the need to be in someone else's database.
* [Decentralized Society: Finding Web3's Soul](https://papers.ssrn.com/sol3/papers.cfm?abstract_id=4105763) 2022-05-11 Glen Wheyl
> Key to this sociality is decomposable property rights and enhanced governance mechanisms—such as quadratic funding discounted by correlation scores—that reward trust and cooperation while protecting networks from capture, extraction, and domination. With such augmented sociality, web3 can eschew today’s hyper-financialization in favor of a more transformative, pluralist future of increasing returns across social distance.

> Web3 - used here as a general term incorporating efforts to enable trustless coordination with blockchain technology - is focused on decentralization. The promise is the ability to connect and work with anyone, anywhere, any time. In this virtual metaverse, there are few rules (and fewer regulations). It’s the blue ocean where anything digital can be quickly created and launched, including entirely new countries.

> Certainly, there is a wide range of opinion on Web 3.0: Cutler mentioned how Elon Musk sees this is more marketing hype than reality. Notably, there is a lot of money being pouring into Web 3.0 — Cutler said, “Venture capitalists have invested $12.75B in 460 different blockchain projects this past year, up from $2.75B in investments during 2020”. Widman said that “With Web 3.0, you have to get to a marketplace of ideas where they can win on their merits,” before the concept will gain traction.

* [WEB2 VS WEB3](https://ethereum.org/en/developers/docs/web2-vs-web3/) 2022-09-27 Ethereum.org
> Web2 refers to the version of the internet most of us know today. An internet dominated by companies that provide services in exchange for your personal data. Web3, in the context of Ethereum, refers to decentralized apps that run on the blockchain. These are apps that allow anyone to participate without monetising their personal data.

> Summary: Building a better internet won't happen by chance or simply maximizing freedom. We have to build systems that support justice. How can we do that? Philosophy discussions are the black hole of identity. Once you get in, you can't get out. Nevertheless, I find that I'm drawn to them

> As Jeremiah pointed out when we bumped into each other last night, public discussion of “web3” is almost completely focused on this last item: tokens, and the many ill-begotten schemes that they have enabled.

> But that is not web3’s lasting attraction. The other four promises – participation in governance, self-sovereign identity, content ownership and the freedom to build – are very appealing.

A credential is issued, and then held for a long period of time with intermittent voluntary presentations to many different verifiers. To put that back into our example, my auto club issues me a card, which I hold in my wallet for years (maybe decades!), and I might choose to show that card to a garage when I need a tow, or possibly to a store to get a discount.

> Self-Sovereign Identity (SSI) is arguably the most effective form of digital identity in Web 3.0. SSI is a user-centric identification method for controlling information. Fully aligned with Web 3.0, SSI eliminates the need to store personal information entirely on a central database and gives individuals greater control over the information they share to protect their privacy.

## EIP - ERC
* [ethereum/EIPs/issues/1056](https://github.com/ethereum/EIPs/issues/1056) - ERC: Lightweight Identity
- This ERC describes a standard for creating and updating identities with a limited use of blockchain resources. An identity can have an unlimited number of delegates and attributes associated with it. Identity creation is as simple as creating a regular key pair ethereum account, which means that it's fee (no gas costs) and all ethereum accounts are valid identities. Furthermore this ERC is fully DID compliant.
* [ethereum/EIPs/issues/780](https://github.com/ethereum/EIPs/issues/780) - EIP-780 Ethereum Claims Registry
* [ethereum/EIPs / eip-712.md](https://github.com/ethereum/EIPs/blob/f29527ab39357548b06b29e937a48f06ae099de7/EIPS/eip-712.md) - EIP712
- This is a standard for hashing and signing of typed structured data
* [ethereum/EIPs/issues/1495](https://github.com/ethereum/EIPs/issues/1495) - ERC-1484 Digital Identity Aggregator
- A protocol for aggregating digital identity information that's broadly interoperable with existing, proposed, and hypothetical future digital identity standards.
* [ethereum/EIPs / eip-1078.md](https://github.com/ethereum/EIPs/blob/ed621645c8f3bc5756492f327cda015f35d9f8da/EIPS/eip-1078.md) - EIP-1078
- This presents a method to replace the usual signup/login design pattern with a minimal ethereum native scheme, that doesn’t require passwords, backing up private keys nor typing seed phrases.
