Pi Network 項目方在台北時間六月九日下午2點30分更新 Pi App 首頁，對於近期區塊鏈盛事上許多專家學者提出區塊鏈公鏈的運行消耗了大量的地球資源(尤其指電力部分)的不同看法和疑慮—明顯的破壞環境，甚至因此產生一定程度上的汙染。為此，Pi Network 就此話題做出說明，釋放疑慮。
進一步的在內頁說明 Pi Network 公鏈節點的共識運算原理和方法，為什麼 Pi 不會消耗大量資源？使用什麼運算方法呢？和其他公鏈的共識基礎不同點在哪裡？
來消除一些學者及廣大先鋒的疑慮。

How can Pi be mined on mobile phones without the energy consumption typically known in “crypto mining”?
如何在沒有「加密挖掘」中通常已知的能源消耗的情況下在手機上挖掘 Pi？
Pi achieves this by using a different type of consensus algorithm in its blockchain rather than the widely-known and energy exhaustive Proof of Work (PoW) . Pi’s consensus algorithm is based on the Stellar Consensus Protocol (SCP) and an algorithm called Federated Byzantine Agreement (FBA), all of which do not require exhaustive energy consumption to reach consensus in order to secure a ledger. These types of consensus algorithms require the nodes to form quorums and exchange messages with each other based on a trust graph composed of individual quorum slices in order to come to “consensus” on what the next block should be.
Pi 通過在其區塊鏈中使用不同類型的共識算法而不是廣為人知且耗費電能的工作量證明 (PoW) 來實現這一點。 Pi 的共識算法基於 Stellar 共識協議 (SCP) 和一種稱為聯邦拜占庭協議 (FBA) 的算法(註：容錯算法)，所有這些都不需要消耗大量的能源來達成共識以確保分類賬的安全。 這些類型的共識算法要求節點形成仲裁併基於由各個仲裁切片組成的信任圖相互交換消息，以便就下一個區塊應該是什麼達成「共識」。
Mining is the process of contributing to the consensus algorithm of a blockchain to secure its ledger in exchange for rewards. While PoW mining requires a lot of energy consumption for nodes to “work” to solve mathematical puzzles to help the algorithm reach consensus, Pi mining requires a distributed trust graph. The security circles of each individual mobile miner will aggregate into a global trust graph that will feed the consensus algorithm of the Pi blockchain. Therefore, each mobile miner mines Pi by contributing to the intersectionality, security and feasibility of the Pi Blockchain’s consensus algorithm in order to secure the Pi ledger. While PoW miners’ contribution to those blockchains is energy, Pi mobile miners’ contribution to Pi Blockchain is their trust relationships and active confirmation of such relationships. The heavy lifting of running the consensus algorithm based on this trust graph aggregated from mobile miners is still done by computer nodes. In fact, the Pi Testnet already has more than 10,000 such computer nodes, placing Pi onto a good path towards creating a very decentralized Mainnet.
挖礦是為區塊鏈的共識算法做出貢獻以保護其分類賬安全以換取獎勵的過程。 PoW 挖礦需要消耗大量能量才能讓節點「工作」以解決數學難題以幫助算法達成共識，而 Pi 挖礦則需要分佈式信任圖。每個單獨的移動礦工的安全圈將聚合成一個全局信任圖(註：安全圈信任網)，該圖將提供 Pi 區塊鏈的共識算法。因此，每個移動礦工都通過為 Pi 區塊鏈共識算法的交叉性、安全性和可行性做出貢獻來挖掘 Pi，以保護 Pi 分類賬。 PoW 礦工對這些區塊鏈的貢獻是能源，而 Pi 移動礦工對 Pi Blockchain (註：Pi 區塊鏈)的貢獻是他們的信任關係和對這種關係的積極確認。基於這個從移動礦工聚合的信任圖運行共識算法的繁重工作仍然由電腦節點完成。事實上，Pi 測試網已經擁有超過 10,000 個這樣的電腦節點，這使 Pi 走上了創建一個非常分散的主網的良好道路。
