## Overview The DWN (Decentralized Web Node) module provides decentralized data storage with encryption, permissions, and protocol management. ## Request: {{.RequestType.Name}} | Field ID | Name | Type | Description | | -------- | ---- | ---- | ----------- | {{range .RequestType.Fields}} | {{.Number}} | {{.Name}} | {{if eq .Label.String "LABEL_REPEATED"}}[]{{end}}{{.Type}} | {{fieldcomments .Message .}} | {{end}} ## Response: {{.ResponseType.Name}} | Field ID | Name | Type | Description | | -------- | ---- | ---- | ----------- | {{range .ResponseType.Fields}} | {{.Number}} | {{.Name}} | {{if eq .Label.String "LABEL_REPEATED"}}[]{{end}}{{.Type}} | {{fieldcomments .Message .}} | {{end}} ## Implementation Details {{if eq .MethodDescriptorProto.Name "RecordsWrite"}} - Creates or updates records in decentralized storage - Supports encryption for sensitive data - Stores data on IPFS with CID references - Enables protocol-based data organization {{else if eq .MethodDescriptorProto.Name "RecordsDelete"}} - Removes records from DWN storage - Can prune descendant records recursively - Maintains deletion history for audit {{else if eq .MethodDescriptorProto.Name "ProtocolsConfigure"}} - Defines custom protocols for data organization - Establishes schema and validation rules - Enables structured data interactions {{else if eq .MethodDescriptorProto.Name "PermissionsGrant"}} - Grants access permissions to other DIDs - Supports fine-grained access control - Can scope permissions to specific protocols or records {{else if eq .MethodDescriptorProto.Name "PermissionsRevoke"}} - Revokes previously granted permissions - Immediate effect on access control {{else if eq .MethodDescriptorProto.Name "RotateVaultKeys"}} - Rotates encryption keys for vaults - Maintains data accessibility during rotation - Supports scheduled and forced rotations {{else if eq .MethodDescriptorProto.Name "Records"}} - Queries records with flexible filters - Supports filtering by protocol, schema, parent - Returns paginated results {{else if eq .MethodDescriptorProto.Name "Vault"}} - Retrieves vault encryption status - Shows key rotation history - Returns vault metadata {{else if eq .MethodDescriptorProto.Name "IPFS"}} - Returns IPFS node status and connectivity - Shows peer count and storage metrics {{else if eq .MethodDescriptorProto.Name "CID"}} - Retrieves data by IPFS Content Identifier - Returns raw data from distributed storage {{end}} ## Storage Architecture - **IPFS Integration**: Large data stored on IPFS network - **On-chain References**: Blockchain stores CIDs and metadata - **Vault Encryption**: Sensitive data encrypted before storage - **Protocol Organization**: Data structured by custom protocols ## Security Features - End-to-end encryption for private data - JWT-based authorization for operations - Granular permission system - Cryptographic attestations for data integrity
