EthDenver 2021 workshop

An example app built with IDX.

Technologies

Ceramic HTTP Client: Provides access to the Ceramic Network via a remote node running Ceramic (and IPFS).
3ID Connect: Provides authentication to a DID (used by Ceramic) from a blockchain wallet, and stores a link from this blockchain account to your DID in IDX.
IDX: Provides a way to create identity records for a DID. Records are stored on Ceramic and can represent links to blockchain accounts or other user data.

Using demo app as a template

Instructions

Install dependencies:

npm ci

Start the development server:

npm start

Install Ceramic and IDX:

npm install -g @ceramicnetwork/cli @ceramicstudio/idx-cli

Run the Ceramic daemon:

ceramic deamon

Create a developer DID used to author the schema and definition:

idx did:create --label=local

Publish the schema (can be found below):

idx schema:publish local '{"$schema":"http://json-schema.org/draft-07/schema#"...'

Create the definition:

idx definition:create local --schema=<schema-url-from-above> --name="Secret Notes" --description="Seret notes for myself and others"

Open the src/idx.ts file and edit the aliases variable secretNotes to the DocID returned by the previous command.

Schema used by this app

{   "$schema": "http://json-schema.org/draft-07/schema#",   "type": "object",   "title": "SecretNotes",   "properties": {     "notes": {       "type": "array",       "items": { "$ref": "#/definitions/NoteJWE" }     }   },   "additionalProperties": false,   "required": [ "notes" ],   "definitions": {     "NoteJWE": {       "type": "object",       "properties": {         "protected": { "type": "string" },         "iv": { "type": "string" },         "ciphertext": { "type": "string" },         "tag": { "type": "string" },         "aad": { "type": "string" },         "recipients": {           "type": "array",           "items": {             "type": "object",             "properties": {               "header": { "type": "object" },               "encrypted_key": { "type": "string" }             },             "required": [ "header", "encrypted_key" ]           }         }       },       "required": [ "protected", "iv", "ciphertext", "tag" ]     }   } }

使用IDX构建的示例应用程序。

技术

陶瓷HTTP客户端：通过运行陶瓷（和IPFS）的远程节点提供对陶瓷网络的访问。
3ID Connect：从区块链blockchain钱包向DID（陶瓷使用）提供身份验证，并在IDX中存储从该区块链blockchain帐户到您的DID的链接。
IDX:提供为DID创建标识记录的方法。记录存储在陶瓷上，可以表示到区块链blockchain帐户或其他用户数据的链接。你知道吗

使用演示应用程序作为模板

说明

安装依赖项：

npm ci

启动开发服务器：

npm start

安装陶瓷和IDX：

npm install -g @ceramicnetwork/cli @ceramicstudio/idx-cli

运行陶瓷守护程序：

ceramic deamon

创建开发人员用于编写架构和定义：

idx did:create --label=local

发布架构（可以在下面找到）：

idx schema:publish local '{"$schema":"http://json-schema.org/draft-07/schema#"...'

创建定义：

idx definition:create local --schema=<schema-url-from-above> --name="Secret Notes" --description="Seret notes for myself and others"

打开src/idx.ts公司文件并编辑将变量secretNotes别名为上一个命令返回的DocID。

此应用程序使用的架构

{   "$schema": "http://json-schema.org/draft-07/schema#",   "type": "object",   "title": "SecretNotes",   "properties": {     "notes": {       "type": "array",       "items": { "$ref": "#/definitions/NoteJWE" }     }   },   "additionalProperties": false,   "required": [ "notes" ],   "definitions": {     "NoteJWE": {       "type": "object",       "properties": {         "protected": { "type": "string" },         "iv": { "type": "string" },         "ciphertext": { "type": "string" },         "tag": { "type": "string" },         "aad": { "type": "string" },         "recipients": {           "type": "array",           "items": {             "type": "object",             "properties": {               "header": { "type": "object" },               "encrypted_key": { "type": "string" }             },             "required": [ "header", "encrypted_key" ]           }         }       },       "required": [ "protected", "iv", "ciphertext", "tag" ]     }   } }
