Solid project
The Solid project, a central project of Web3, is described here.
<Overview>
The Solid project was proposed by Sir Tim Berners-Lee, the founder of the World Wide Web, to build a decentralised web. and aims to enable users to own, manage and control their own data, the main aim of the project will be to address current problems with the centralisation of the web and the collection of personal data.
The central idea of the Solid project is that users will have personal data storage, called ‘pods’, where they can own, collect and control their own data, which will be represented based on standard Linked Data protocols, and users can use this The data can be shared with applications and services and access rights can be set as required.
The main features and objectives of the Solid project include
1. Data ownership and control: users can own their data and control access rights.
2. data decentralisation: data is distributed across pods of users, rather than in a centralised database, and data sharing is under user control.
3. portability: data can be easily moved between applications and services of the user’s choice.
4. interoperability: Solid is built on open standards, enabling it to work with different platforms and applications.
The Solid project will address key issues related to data ownership, privacy and security of personal data, and will seek to create a user-centric web. The progress of the project can be found on the official website and in relevant sources.
<About the tools used in the Solid project>
The Solid project is a project to realise a decentralised web, for which various tools and applications have been developed. Some of the tools and applications created by the Solid project are described below.
1.Solid POD:
The Solid POD (Personal Online Data Store) is a central element in the Solid project, a decentralised data storage where users can securely store and control their personal data, including
Inrupt Solid Server : open source server software by Inrupt, a company founded by Solid founder Tim Berners-Lee and working to promote the Solid project, which can be used to implement Solid POD and host Solid PODs themselves.
Solid Community Servers : A hosting service for Solid PODs run by the community. Users can choose these servers to create Solid PODs and store their data; Solid Community Servers provide an easy way for users to host their own data.
Solid Sakurai Project: an organisation that works with Japanese research institutes and companies to implement and promote the Solid project; the project implements Solid PODs, translates them into Japanese and organises related events.
<For an example of an implementation of the Inrupt Solid Server>
The basic steps for implementing Solid POD using Inrupt Solid Server are shown below.Inrupt Solid Server is an open source software associated with the Solid project, which can be used to host Solid POD.
The following outlines the steps for implementing Solid POD using Inrupt Solid Server.
Install Node.js: Inrupt Solid Server runs on Node.js, so first install Node.js, which can be downloaded from the official website.
Installing Inrupt Solid Server: open a terminal or command prompt and install Inrupt Solid Server using the following command.
npm install -g solid-serverSolid Server setup: once the installation is complete, the Solid Server needs to be set up. Use the following commands to start the setup process.
solid initThis command performs the initial configuration of the Solid Server. It provides configuration information and allows you to specify the Solid POD data directory and storage location for user accounts.
Starting the server: once the Solid Server setup is complete, start the server using the following command
solid startOnce the server is up and running, access to the Solid POD is possible. By default, it can be accessed at http://localhost:3000.
Creating a user account: if the server is running, a new user account can be created by accessing http://localhost:3000 with a web browser. Once a user account has been created, Solid POD is available.
Manage data and set access rights: upload data into Solid POD and set access rights as required; manage data via Solid Server and share data with other users and applications.
Linking applications: select and link Solid applications to use Solid POD. This enables data to be stored, edited and shared.
Data utilisation: data can be stored in the Solid POD and utilised through the Solid application. This allows the use of calendar applications, file sharing applications, communication applications, etc.
By following these steps, you can use Inrupt Solid Server to set up Solid PODs, store data securely and ensure security and privacy. If required, the Solid Server configuration can be customised, and the Solid project community and documentation are also valuable resources to provide support.
2. dokieli: dokieli is a distributed web authoring tool, which will be developed as part of the Solid project to create and view rich content on the web using Semantic Web technologies.
3. the Solid POD browser: special web browsers developed under the Solid project aim to allow users to store and control their data in Solid PODs (personal data storage). These browsers give users ownership of their data and emphasise privacy.
4. the Solid Data Browser: the Solid Data Browser will be a tool for viewing, editing and managing data in the user’s Solid POD. Users can organise their personal data, set access rights and share data when required.
5. Solid applications: the Solid project encourages an application ecosystem for decentralised handling of data, and different types of applications have been developed based on Solid principles, such as calendar apps, file sharing apps, communication apps, etc. 4. Inrupt: the core of the Solid project.
6. Inrupt: a core component of the Solid project, Inrupt will be a company set up to support the Solid implementation and ecosystem Inrupt provides tools and services for controlling data based on Solid principles.
These tools and applications aim to help users regain ownership and control of their data and improve the security and privacy of personal data The Solid project will enable a decentralised web and improve the modern web experience The technology will be a high-profile part of the initiative.
Solid applications
The Solid application will be an application developed based on the principles of the Solid project, which aims to create a decentralised web experience in which users regain ownership and control of their data The Solid application will have the following characteristics Features.
1. data decentralisation and ownership: the Solid application allows users to store their data in Solid PODs (personal data storage) and take ownership of their data. Data is stored in decentralised PODs rather than in a centralised database.
2. data security and privacy: the Solid application is designed to enhance the security and privacy of personal data. Users can set access rights to their data and control the sharing of data to other users and applications.
3. linked data and semantic web: Solid applications utilise linked data and semantic web technologies to semantically link data and information and present it in a machine-understandable format.
4. application diversity: many different applications have been developed to address different types of tasks and uses of Solid applications. These include calendar applications, file sharing applications, communication applications, social networking applications, etc.
5. interoperability: Solid applications comply with the standards of the Solid project and allow integration with different applications and services. Users can easily move their data between different applications.
The following are examples of specific Solid applications.
- Solid File Manager: the Solid File Manager is a web-based file manager for managing files and directories within Solid PODs. Users can upload, download, share and delete files within the Solid POD.
- Solid Chat: Solid Chat is an application that uses the Solid POD for live secure chat messaging. Users can chat with other users through Solid Chat and control message storage and privacy.
- Solid Calendar: Solid Calendar is an application for managing calendar information within Solid PODs. Users can create, view, edit and share appointments within the Solid POD.
- Solid Social Media Apps: several social media applications also utilise Solid PODs to provide a decentralised social platform. These applications allow users to control their own data and enable social communication.
- Solid Health Apps: the Solid project is also developing applications for secure management of healthcare-related data. Users can use Solid PODs to store and share health data and medical records.
- Solid Data Sharing Apps: there are also applications that enable data sharing and collaboration using Solid PODs. Users can share data and collaborate with other users and applications.
These are examples of common Solid applications.The goal of the Solid project will be to provide a web experience where users can own and secure their data. This will enhance data ownership and privacy and enable effective management of data. Many applications have adopted the Solid protocol and are being developed to achieve these goals.
To implement such Solid applications, web applications need to be developed to retrieve, update and share user data based on the Solid protocol. The basic steps to implement Solid applications and specific implementation examples are described below.
Implementation steps for a Solid application:.
1. design the web application: first, plan and design what Solid application will be developed. Clearly define the purpose and functionality of the application so that users can read, write and share data from the Solid POD.
2. understanding the Solid protocol: understand the Solid protocol and learn the API for users to retrieve and update data in the Solid POD. This includes Solid’s data model, linked data and webIDs.
3. develop a web application: develop a web application. Typically, design the front end using HTML, CSS and JavaScript, and establish communication with the back end using the Solid protocol.
4. use of Solid libraries: use Solid libraries and frameworks to simplify communication with Solid PODs and improve the user experience; libraries such as Solid React and rdflib.js are available for Solid applications.
5. user authentication and security: when users access the Solid application, the Solid protocol is used for user authentication. Access control and security of data should also be considered.
6. data retrieval and updating: retrieve data from Solid PODs, update, delete and create new data; the Solid application will manipulate data in compliance with linked data and semantic web principles.
7. data sharing and collaboration: the Solid application works with Solid PODs to share data in conjunction with other Solid applications. This allows users to use data with multiple applications.
These implementation examples can utilise web development technologies such as JavaScript and React.
Application of NFT technology
Combining the Solid project with NFTs opens up new possibilities for decentralised management of personal data and digital ownership at the same time – Solid is a decentralised framework for individuals to manage their data independently, while NFTs (non-substitutable tokens) are a mechanism to prove ownership of assets on the blockchain. The NFT (Non-Functional Token) is a mechanism for proving ownership of assets on the blockchain. Combining the two will enable users to have full ownership and control over their personal data and prove the authenticity and uniqueness of their data and digital content, while securely sharing their data with others.
The benefits of combining NFT with the Solid project include
Complete data management: users are free to manage, share and trade their data, enhancing privacy and security.
Valorisation of digital assets: by associating NFT with data and content, digital assets can be given economic value.
Transparency and trust: the usage of data and content is recorded on the blockchain, increasing transparency.
Specific ideas for how this could be achieved include
1. proving data ownership with NFTs: by associating NFTs with data stored by users in Solid (e.g. self-introductions, social networking posts, etc.), it is possible to prove that the data is owned by the user in a tamper-proof manner.
2. sharing content and assets: setting access and usage rights to specific data and digital assets through NFTs and managing access using blockchain; ensuring that data in Solid’s pods (personal data storage) can only be seen by designated people; licensing through NFTs management is possible.
3. tracking and controlling data access: by representing the data stored in Solid with NFTs, the history of access rights is recorded in the blockchain, allowing the user to know who has accessed the data and how many times. This enables users to have detailed control over their data usage.
4. decentralised identity and digital identity: user identity data (e.g. profile information) is NFTed to build a trusted digital identity. This enables users to have a consistent digital identity across different services.
Combining NFT with the Solid project in this way enables the management of personal data and the protection of ownership of digital assets, bringing more trust and value to users.
