The PCHAIN Network is a new infrastructure level public chain system with native support for multi-chain applications and EVM. It provides an open, scalable platform for third party developers in the industry, enabling large-scale enterprise applications based on smart contracts. The core technologies of the PCHAIN Network include:

1. The first native multi-chain architecture that supports EVM, with a consensus of POS based on a multi-layer sharding mechanism that greatly improves transaction performance.
2. A new Oracle mechanism based on the knowledge graph, which makes it easier to encapsulate smart contracts. The endogenous W3C-compliant smart data of the PCHAIN Network effectively addresses the issue of non-intelligence in smart contracts and can become a fundamental element of smart contracts, similar to market exchange rate data from external sources.
3. The goal of PCHAIN Smart Data is to generate valuable data that filters out noise and make it an integral part of Oracle. These smart data can be used in various smart contracts and other cross-chain requests on the PCHAIN Network. Smart data serves as an intermediary between blockchain and artificial intelligence, facilitating the integration of blockchain with big data. It has vast application prospects, including decentralized question and answer, forecasting markets, distributed knowledge graph building, social networks, digital identities, and more.
4. The trunked cross-chain solution makes the exchange of digital currency and digital assets more convenient. Various Tokens (e.g. BCH, ERC20) can be directly used to invoke smart contracts in the PCHAIN Network.

Pi Network is aware of reports that several unauthorized third-party exchanges, and potential unknown third parties, are seeking to list Pi or tokens purporting to be Pi, or some purported derivative of Pi, without the consent, authority, or involvement of Pi Network.

Pi is currently in the Enclosed Network period of Mainnet and is not approved by Pi Network for listing on any exchange or for trading, and Pi Network is not involved with any purported postings or listings.

The Network is NOT having any ICOs or any type of crowdfunding, and any sales of Pi are unauthorized and have no affiliation with Pi Network.

Currently, Pi Network recommends to all Pioneers and potential Pi users not to engage with any of these exchanges or third-party actors as their actions are not affiliated with Pi Network, and could result in substantial loss or damage to Pi users. Pi Network is also requesting these posts and exchange listings removed, and evaluating additional actions with respect to the third parties and exchanges. In the interim, it is important to reiterate that the transaction of Pi through an exchange is explicitly prohibited during the Enclosed Mainnet period, and doing so would be a violation of Pis policies.

Pi Network is a social cryptocurrency and developer platform that (1) allows mobile users to mine Pi coins without draining battery or harming the environment and (2) fosters the worlds most accessible and ubiquitous apps platform where developers can offer users real-life utilities and products in exchange for Pi coins.

With its 35+ million engaged user base and novel mining mechanism that allows anyone to mine Pi straight from their smartphones, Pi Network strives to bring real power back to the masses. Pis blockchain secures not only transactions via a mobile meritocracy system but also a full Web 3.0 experience where community developers can build decentralized applications (dApps) for millions of users.

Pi Network is founded by Dr. Nicolas Kokkalis and Dr. Chengdiao Fan—two Stanford PhDs in computational engineering and social sciences.

Dr. Kokkalis, in addition to developing/founding several startups and human-centered technologies in the past, teaches Stanfords computer science class, Decentralized Applications on Blockchain.

Dr. Fan, receiving her PhD in computational anthropology, has also worked as a founding developer of several startups and projects around scaling social communications and surfacing untapped social capital for people everywhere.

Both are strong and long-term believers in the technical, financial, and social potential of cryptocurrencies, but frustrated by their current limitations. To resolve traditional blockchains shortcomings, they employ a user-centric design philosophy that turns the development process of new blockchains upside down.

Pis blockchain uses an adaptation of the Stellar Consensus Protocol (SCP)—an instantiation of the Federated Byzantine Agreement—to validate transactions.

Compared to traditional blockchain mining methods like Proof-of-Work or -Stake, Pis protocol uniquely provides decentralized control, low latency, flexible trust, and asymptotic security at a fraction of the environmental cost. In short, fault tolerance is achieved through a decentralized web of nodes reaching consensus via a trust network of mobile users who validate their daily presence and vouch for others authenticity in the network to earn Pi. Environmental impact is vastly lowered since this method does not require energy-intensive hardware to mine.

Pi Networks robust ecosystem design is built on an intuitive and transparent model, facilitating Pi coins as a medium of exchange without token concentration. Key tenets include fair distribution (everyone mines at the same rate), scarcity (the mining rate decreases as more people join), and meritocracy (rewards are distributed based on contributions to the network).

Pi Networks developer platform also offers numerous qualities that may interest developers. As the worlds largest identity-authenticated userbase, Pi Network has pre-built infrastructures such as a crypto wallet, user authentication, notifications, deep linking, app interoperability, and many other functionalities in the pipeline. Its App Engine uses an operating system similar to Apples iOS, with a secure blockchain component. Community developers can incorporate Pis SDK and user-authentication measures into their apps, enabling Pioneers to seamlessly integrate into the Pi ecosystem and move back and forth between different interoperable apps without logging in separately or providing other contact information.
