Pi Network’s Pi Node (Pi Desktop) Explained: Roles, Setup, Selection Criteria, and Future

Recently, the term “decentralization” has gained significant attention alongside the concept of Web3. Pi Network, a smartphone mining app gaining global popularity, is a project striving to realize this decentralized network vision.

In Pi Network’s envisioned decentralized future, the Pi Node (now Pi Desktop) plays a crucial role. Alongside mobile app mining, Pi Nodes serve as the backbone, maintaining network security and integrity.

This article provides a comprehensive explanation of Pi Node (renamed Pi Desktop in the latest Pi Network update), covering its role, participation levels, selection criteria, and future roadmap. Even without specialized knowledge, you’ll gain a deep and accurate understanding.

How will you contribute to Pi Network’s future? Through this article, gain insight into the importance and potential of Pi Nodes and take the next step in your engagement with the Pi Network ecosystem.

What is a Pi Node? Its Role in Supporting the Decentralized Network

A Pi Node is a crucial computer application that validates and records transactions on Pi Network’s decentralized ledger (blockchain). Similar to other blockchains, consensus among all nodes on the transaction order solves the challenges of maintaining a decentralized currency.

Pi Network’s Stellar Consensus Protocol (SCP)

Unlike Bitcoin and Ethereum, which use the energy-intensive “Proof-of-Work (PoW)” consensus algorithm, Pi Nodes utilize the Stellar Consensus Protocol (SCP), a different approach.

SCP involves nodes forming groups of trusted nodes (called “quorum slices”), agreeing only on transactions approved by these trusted nodes. This mechanism works in conjunction with the “security circles” formed by mobile miners, creating Pi Network’s unique global trust graph to determine who can and cannot validate transactions on the shared ledger.

This allows Pi Network to be more environmentally friendly and accessible, avoiding the massive energy consumption of typical PoW systems.

User-Centric Design Philosophy

Unlike many crypto projects, Pi Node prioritizes a “user-centric” design. Instead of requiring deep technical expertise for node setup, it’s designed for ease of participation; users simply install the desktop application on their computer. This approach aims for a truly decentralized ecosystem.

Three Pi Node Participation Levels: Find Your Contribution

The Pi Node software (Pi Desktop) offers three participation levels based on technical involvement. Each level has different roles and requirements, allowing users to contribute according to their capabilities.

1. Pi Desktop (formerly Computer App): Easily Connect with Pi Network

  • Role & Function: This level uses only the desktop app interface of the Pi Node software, providing similar functionality to the Pi Network mobile app on your PC. For example, view your Pi balance on a larger screen, use the chat function, or view media content.
  • Technical Requirements: No special technical knowledge or configuration is needed; it’s as easy as installing a typical PC app.
  • Features & Contribution: Improves accessibility to the Pi Network ecosystem and increases user engagement. However, this level doesn’t provide mining bonuses.

2. Pi Node: Become a Blockchain Validator

  • Role & Function: Access the Pi Node interface and follow instructions to complete necessary technical preparations (e.g., port forwarding). This allows your computer to run blockchain components, validating transaction validity and submitting transactions to be recorded on the blockchain. It doesn’t directly participate in consensus formation.
  • Technical Requirements:
    • Port forwarding
    • Suitable processor and memory (recommended specifications available)
    • Stable, high-speed internet connection
  • Features & Contribution: Contributes to network health and security, promoting Pi Network’s decentralization. Mining bonuses are possible at this level.

3. Pi Super Node: Supporting the Network’s Backbone

  • Role & Function: The most crucial role, forming the backbone of the Pi blockchain. In addition to all Pi Node responsibilities, it’s responsible for forming consensus to write appropriate transactions to the ledger and ensuring other Super Nodes and Nodes receive the latest blockchain state.
  • Technical Requirements: In addition to Pi Node requirements, a constant connection and highly reliable internet connection are necessary.
  • Features & Contribution: Essential for maintaining network stability and decentralization; selected by the core team. Offers the highest potential rewards due to its advanced contribution.

These three participation levels are further compared in the table below:

Participation Level Role & Function Technical Requirements (Main) Features & Contribution
Pi Desktop Use similar functions of the Pi Network mobile app on a PC (chat, balance check, etc.) No special technical knowledge required Easy access to Pi Network
Pi Node Transaction validation, submission, and recording on the decentralized ledger Port forwarding, appropriate PC specifications, stable internet connection Verifies blockchain integrity, contributes to network decentralization
Pi Super Node Pi blockchain backbone. Consensus formation, state synchronization Node requirements plus constant connection, high reliability, excellent internet connection Maintains network stability and decentralization

Security warnings like Microsoft Defender SmartScreen may appear when installing the Pi Node software, a common occurrence with new apps being installed by many users. As Pi Network’s user base grows, these warnings tend to disappear.

Pi Node/Super Node Selection Process and Criteria

To function as a Pi Node or Pi Super Node in Pi Network’s Testnet, download and install the Pi Node software on your computer. Follow the instructions within the Pi Node application, install the necessary technical packages, and keep the software running continuously. There isn’t a separate “application” screen; the process of correctly setting up and stably running the software is considered the application process itself.

The Pi Network core team then selects Nodes and Super Nodes based on the following criteria. Nodes and Super Nodes are evaluated using similar criteria, but the threshold for Nodes is set lower than for Super Nodes.

Selection Criteria

  • Uptime: Online 24/7 as much as possible.
  • Good Internet Connection: Fast and stable internet access.
  • Port Forwarding Capability on Local Router: Configuration enabling external communication.
  • Appropriate Processor and Memory: PC hardware specifications necessary for smooth node operation. At least 250MB of free disk space is recommended, but older PCs may lack sufficient performance.
  • Prior Community Contributions: Active participation in the Pi Network community.
  • Security Circle and Trust Score: Indicators of trustworthiness within Pi Network.
  • KYC (Know Your Customer) Completion: The process verifying the participant is a real person.

Selected Node and Super Node applicants are typically notified through the Pi Node interface over a period of about three months. Pi Network aims to be as inclusive as possible and plans to develop additional ways for more pioneers to access the Node role in the future.

Pi Network Testnet Roadmap: The Path to Decentralization

Pi Network presents a three-stage Testnet roadmap towards building a fully decentralized Mainnet. This roadmap is crucial for ensuring network stability, security, and scalability.

1. Selection Phase

  • Purpose: The core team runs the consensus algorithm on pioneers’ computers who have applied to be Nodes and successfully installed the necessary packages. This allows them to understand individual Node requirements (hardware, uptime, bandwidth, connection stability, etc.) and define appropriate thresholds to balance network security and activity.

2. Revision Stage

  • Purpose: Scenario testing and iterative improvement of the consensus algorithm. Stress tests simulating various scenarios (e.g., half the network is isolated, a Node suddenly stops/is compromised) are conducted to determine algorithm modifications and application methods for ensuring security, improving activity, and achieving scalability.
  • This stage includes a centralized layer to allow the core team to assign simulated data of the network graph and configuration to different Nodes, enabling efficient testing of a wide range of scenarios. This centralized layer will be removed in the Mainnet after serving its testing purpose.

3. Live Testnet

  • Purpose: After the selection and revision stages, various Node types actively fulfill their responsibilities. The network’s performance is tested using real data from security circles generated by mobile miners and the actual activities of network participants. This stage also includes an iterative process of testing, data analysis, debugging, and revision, continuing the pursuit of security, liveness, and scalability.

Through these stages, Pi Network addresses unique challenges (a large number of participants, decentralization of PCs as Nodes, integration of trust graphs from mobile miners, etc.) and advances the adaptation and expansion of SCP tailored to the needs of the Pi blockchain.

Frequently Asked Questions (FAQ) about Pi Node

Q. What’s the relationship between Pi Node software and the Pi Network mobile application?

A. The Node software and the mobile app are not mutually exclusive but complementary. You log in to the Node software using your mobile app account, linking them to the same Pi account.

Pi Network for Beginners: A Comprehensive Guide to the Pros and Cons of Smartphone Crypto Mining

コメントを残す

Pi Network is a blockchain project whose major feature is the ability to “mine” cryptocurrency on a smartphone. In traditional cryptocurrency mining, it was common to require high-performance computers and large amounts of electricity. However, Pi Network has attracted attention because mining can be done with a single tap from a smartphone app, without the need for special hardware.

Reasons Why Mining on a Smartphone is Possible

Pi Network is designed to perform the mining process in a way that consumes very little energy. Generally, cryptocurrencies that adopt the PoW (Proof of Work) method require vast calculations that involve significant power consumption. On the other hand, Pi Network utilizes the Stellar Consensus Protocol (SCP), and users can continue mining simply by launching the app and tapping a button every 24 hours. Since it doesn’t require large-scale hardware like CPUs or GPUs to run at full capacity for mining, the benefits include not only power saving but also minimal noise and heat issues.

Consensus Formation and Network Mechanism via SCP

The Stellar Consensus Protocol (SCP), adopted by Pi Network, has a mechanism for reaching transaction consensus based on a web of trust (security circles). Instead of competing through calculations like in the traditional PoW method, participants register trusted peers, and the entire network validates transactions. This is said to enable safe and efficient transaction processing while reducing energy consumption.

However, since smartphones serve as the primary nodes (units on the network), scalability issues such as transaction processing speed and node synchronization efficiency when scaled up are not fully resolved. Pi Network has not yet fully transitioned to the open network phase, and further technical ingenuity will likely be required to test its behavior under increased network load.

Comparison with Traditional PoW and PoS

Major consensus algorithms for cryptocurrencies include PoW (Proof of Work) and PoS (Proof of Stake). PoW, adopted by Bitcoin, requires vast power consumption and computational power. On the other hand, PoS, which Ethereum recently transitioned to, requires staking (collateralizing) a certain amount of coins to validate transactions.

  • PoW (Proof of Work): High power consumption, powerful mining machines are essential
  • PoS (Proof of Stake): Selection of validators based on coin holdings, relatively energy-efficient
  • SCP (Stellar Consensus Protocol): Adopted by Pi Network, consensus formation via web of trust

In the case of Pi Network, users do not need to collateralize any amount of coins. Since participation in mining is possible simply by launching the app and tapping daily, it has the characteristic of being overwhelmingly low-barrier for beginners. However, from a security perspective, the addition of managing a 24-word key phrase introduces another aspect of risk.

24-Word Security Key Phrase and Asset Protection

For Pi Network wallet management, holding a 24-word security key phrase is essential. This is the very means of accessing the user’s assets, and if it leaks externally, there is a risk of your Pi coins being stolen. While similar key phrases exist in many traditional cryptocurrency wallets, the increasing number of smartphone users has made lax management a factor that heightens security risks.

For example, saving a screenshot on your smartphone, sharing it with others via chat apps, or backing it up in plain text on online storage significantly increases the risk of the key phrase leaking. Therefore, when operating Pi Network, it is recommended to write it down offline as a memo and store it in a safe place such as a safe or security box.

How to Securely Store Your Pi Wallet Recovery Phrase

Convenience Unique to Smartphone Mining and Points to Be Careful About

The greatest convenience brought by smartphone mining is that it can be started “anywhere, by anyone, easily.” The idea that cryptocurrency accumulates simply by installing an app, registering as a user, and pressing a button daily is low-barrier and attractive even for those new to blockchain. Furthermore, there is no need to assemble expensive machines, nor is there the stress of worrying about home electricity bills.

On the other hand, there is a possibility that the majority of users are not skilled engineers, leading to issues during network expansion. For example, with the increase in new participants, strengthening the support system is required for issues like node synchronization delays or wallet operation errors. Also, from the system development team’s perspective, it is necessary to continuously improve the transaction processing capability and the mechanism for maintaining trust between nodes when the blockchain becomes open.

Where is Pi Network Heading?

Pi Network is attracting attention as an entity that can contribute to the popularization of cryptocurrency, designed to easily incorporate a vast number of smartphone users. It has significant power to approach those unfamiliar with blockchain technology and the potential to spread the concept of cryptocurrency to a wide range of users. When it becomes an open network in the future and progresses to the stage of linking with external exchanges and developing practical DApps, the actual value verification will finally begin in earnest.

Nevertheless, the mainnet has not yet reached a complete form accessible to everyone, and it remains unknown how much global usage the SCP-based mechanism can handle. Achieving smooth transactions while maintaining network decentralization requires technical challenges and community collaboration. The key to Pi Network’s widespread adoption will be how well it can balance convenience, security measures, and trustworthiness as a blockchain.

Points to Note When Using Pi Network and Summary

When starting Pi Network mining, please pay particular attention to the following points:

  • Store the 24-word security key phrase safely offline
  • Implement security measures on your smartphone and update the OS and apps as appropriate
  • Do not easily share the key phrase on social media or chat apps
  • Do not click on suspicious links and do not neglect malware protection

Neglecting these basic measures poses a serious risk of losing the cryptocurrency you have mined or having your account hijacked. What Pi Network aims for is to “allow more people to easily participate in the world of blockchain and cryptocurrency,” and its unique concept has the potential to bring a new wave to the market.

In the future, if measures to enhance network decentralization and scalability are put in place and it gains the trust of many users, Pi Network may become a presence comparable to existing PoW and PoS-based cryptocurrencies. How it actually grows and how it will affect the cryptocurrency landscape as a whole will make it a project that continues to attract attention.
