400萬FIL測試網獎勵計劃7月20日啟動；經濟模型參數即將確定 | 6月26日AMA完全整理

6月26日, 北京時間上午10點，Filecoin項目創始人胡安貝尼在Slido上進行了線上問答活動。一小時的時間裡，胡安和其他幾位Filecoin開發者在線上回答關於測試網激勵和主網上線的40個問題。

火星雲礦（mclouds.io）跟蹤翻譯整理，其中關鍵信息點如下：

1. 測試網的激勵機制基於原始位元組算力、交易完成和扇區生命周期參與度；

2. 為了最大程度的獲得訂單，將需要大量存儲空間，良好的網路連接以及相當好的硬體；

3. 在硬體方面，AMD比intel更適用於目前的演算法；

4. 從現在開始，我們要做的就是修復錯誤，提高性能以及使用新的API和文檔改進UX；

5. 400萬FIL測試網獎勵計劃將於7月20日開始；

6. 試圖「欺騙」其位置的礦工將完全沒有資格獲得所有獎勵；

7. 即使有一些大型礦池，任何人都可以加入網路並只需購買少量硬體即可提供存儲，我們希望客戶將其文件存儲在許多不同的礦工中；

8. 主網經濟模型參數將在7月確定；

9. 如果礦工丟失了數據，數據無法恢復。但如果數據本身是可恢復的，礦工可以通過恢複數據重新獲得該扇區；

10. 礦工和客戶之間交易的最短時長由礦工提單的時候決定，目前最低限制是1個月。 

完整Q&A內容由火星雲礦（mclouds.io）翻譯整理：

1. Can the hard disk of fil discover catch up with the incentive competition on July 20 in time?

（官方Filecoin Discover的硬碟（發貨進度）能趕上7月20日的測試網獎勵競賽嗎？）

Filecoin Discover and testnet incentives are not related. Testnet incentives are based on raw byte-power, deal completion, and sector lifecycle participation. Filecoin Discover hard drives, and the verified client mechanism in general, have no impact on incentives.

（Filecoin Discover和testnet獎勵沒有關係。Testnet的激勵機制基於原始位元組算力、交易完成和扇區生命周期參與度。一般來說，Filecoin Discover硬碟驅動器和驗證客戶端機制不會對激勵產生影響。）

2. What are the main factors for obtaining orders after filecoin go online? Algorithm? Hardware?Is there a difference between Intel and AMD? 

（Filecoin上線後獲得訂單的主要因素是什麼？演算法？硬體？英特爾和AMD之間有區別嗎？）

To maximise the deals being made with your miner, you』ll need lots of storage, a good network connection, and reasonably good hardware (AMD works much better, see: https://github.com/filecoin-project/lotus/blob/master/documentation/en/sealing-procs.md).

--Aayush

（為了最大程度地與您的礦工進行交易，您將需要大量存儲空間，良好的網路連接以及相當好的硬體（AMD的性能要好得多，請參閱：https://github.com/filecoin-project/lotus/blob/master/documentation/en/sealing-procs.md））

3. How likely is the NSE algorithm to come on line later?Is AMD's configuration the most consistent with the current SDR algorithm.

（NSE演算法發布的可能性有多大？AMD的配置與當前的SDR演算法最一致嗎？）

About NSE: NSE is one of the best candidates for a proof upgrade, and teams are working on implementation. But there are other candidates too, which are promising as well. It may be that another algorithm ends up better than NSE -- we don』t know yet. Proof upgrades will arrive after mainnet launch and will coexist.

Yes, AMD may be optimal for SDR, see this for why: https://github.com/filecoin-project/lotus/blob/master/documentation/en/sealing-procs.md

（關於NSE：NSE是進行證明升級的最佳候選之一，並且團隊正在努力實施。但是也有其他候選，也很有希望。可能是另一種演算法的結果比NSE更好-我們尚不知道。證明升級將在主網啟動後到來並共存。

是的，AMD可能是SDR的最佳選擇，原因如下：https://github.com/filecoin-project/lotus/blob/master/documentation/en/sealing-procs.md）

4. What are the changes to the algorithm and logic layer of lotus and go-filecoin before going online?

（上線之前，Lotus和go-filecoin的演算法和邏輯層有哪些變化？）

No changes to 「algorithm and logic」 before we go live -- from here on out, all we』re doing is fixing bugs (so please report them!), improving performance (our sync is *much* faster on the latest Testnet), and improving the UX with new APIs and documentation.

（在我們上線之前，「演算法和邏輯」沒有變化

從現在開始，我們要做的就是修復錯誤（因此，請報告錯誤！），提高性能（在最新的Testnet上，我們的同步*快得多*）以及使用新的API和文檔改進UX。）

5. Will the 4M incentive program start on 20th of July?

（400萬的測試網獎勵計劃是否將於7月20日開始？）

Yes.

6. Has Filecoin confirmed the use of SDR algorithm? Is there any evidence of malicious construction???

（Filecoin是否已確認使用SDR演算法？是否有惡意構造的證據？??）

SDR is confirmed for mainnet launch, and we have no evidence of malicious construction. The algorithm is also going through both internal and external security audits.

If you have any information about any potential security problem or malicious construction, reach out to our team at security@filecoin.org.

（SDR已確認可用於主網啟動，並且我們沒有惡意構建的證據。該演算法還正在進行內部和外部安全審核。

如果您有任何有關任何潛在安全問題或惡意構建的信息，請通過security@filecoin.org與我們的團隊聯繫。）

7. In the coming SpaceRace, how to identify a miner's real location？

（在即將到來的SpaceRace中，如何識別礦工的真實位置？）

We』ll use a variety of technical and non-technical mechanisms. They may also be different for different miners. To avoid cheating, we』re not revealing the specific mechanisms until verification begins.

When we verify miners』 locations, we』ll reach out by email and coordinate a time that the miner will be standing by to provide verification. We』ll ask for some specific evidence and require submission within a short time period.

Location verification is not required to participate in either (i) the global leaderboard or (ii) the regional leaderboard for the most competitive region (i.e., the region with the most storage).

We consider the location of the storage and sealing hardware to be the location of the miner.

Please note that miners who attempt to 「spoof」 their location will be completely ineligible for all rewards.

我們將使用各種技術和非技術機制。對於不同的礦工，它們可能也有所不同。為避免作弊，在驗證開始之前，我們不會透露具體的機制。

驗證礦工的位置後，我們將通過電子郵件與他們聯繫，並協調礦工待命的時間以提供驗證。我們將要求您提供一些具體證據，並要求在短時間內提交。

不需要提交地址證明來參加（i）全球排行榜或（ii）最具競爭力的區域（即存儲量最大的區域）的區域排行榜的位置驗證。

我們認為存儲和密封硬體的位置就是礦工的位置。

請注意，試圖「欺騙」其位置的礦工將完全沒有資格獲得所有獎勵。

8. Is there a miner's KYC certification process? By which way? How to identify the mining location of miners?

（有礦工的KYC認證流程嗎？用什麼方式 如何識別礦工的採礦地點？）

To receive tokens, miners will be required to verify their identity by providing passports or similar identity documents. We may need to request additional information in rare cases.

We』ll use a variety of technical and non-technical mechanisms. They may also be different for different miners. To avoid cheating, we』re not revealing the specific mechanisms until verification begins.

When we verify miners』 locations, we』ll reach out by email and coordinate a time that the miner will be standing by to provide verification. We』ll ask for some specific evidence and require submission within a short time period.

Location verification is not required to participate in either (i) the global leaderboard or (ii) the regional leaderboard for the most competitive region (i.e., the region with the most storage).

We consider the location of the storage and sealing hardware to be the location of the miner.

Please note that miners who attempt to 「spoof」 their location will be completely ineligible for all rewards.

（我們認為存儲和密封硬體的位置就是礦工的位置。

請注意，試圖「欺騙」其位置的礦工將完全沒有資格獲得所有獎勵。）

我們將使用各種技術和非技術機制。對於不同的礦工，它們可能也有所不同。為避免作弊，在驗證開始之前，我們不會透露具體的機制。

驗證礦工的位置後，我們將通過電子郵件與他們聯繫，並協調礦工待命的時間以提供驗證。我們將要求您提供一些具體證據，並要求在短時間內提交。

不需要提交地址證明來參加（i）全球排行榜或（ii）最具競爭力的區域（即存儲量最大的區域）的區域排行榜的位置驗證。

我們認為存儲和密封硬體的位置就是礦工的位置。

請注意，試圖「欺騙」其位置的礦工將完全沒有資格獲得所有獎勵。

9. How to realize reward network retrieval and real data？

（如何實現獎勵網路檢索和真實數據？）

During the competition, once your miner has > 0 storage power, many bots will begin attempting storage and retrieval deals with your miner. The competition dashboard will display your deal success rate in near-real time. Miners below a certain high threshold will be ineligible to receive rewards.

We plan to run the bots for one to two weeks before the competition to give miners a chance to test their configuration, and will announce when that begins.

（在比賽中，一旦您的礦工的存儲功率大於0，許多機器人將開始嘗試與您的礦工進行存儲和檢索交易。競爭儀錶板將近實時顯示您的交易成功率。低於某個高門檻的礦工將沒有資格獲得獎勵。

我們計劃在比賽前將機器人運行一到兩周，以使礦工有機會測試其配置，並會宣布何時開始。）

10. The Filecoin Client is not usable enough, so how to give a deal by customers when mainnet launch？

（Filecoin客戶端無法充分使用，那麼在主網啟動時如何由客戶進行交易？）

Improving the UX and fixing bugs is our only priority right now. We』re excited to be fixing all the issues the community is reporting, so please keep complaining (file issues on Github, and post in #fil-lotus on Slack).

（改進UX和修復錯誤是我們目前唯一的優先事項。我們很高興能解決社區報告的所有問題，因此請繼續抱怨（在Github上提交問題，並在Slack上的＃fil-lotus中發布）。）

11. Lotus or Gofilecoin,which is better for miners?

（Lotus或Gofilecoin，哪個對礦工更好？）

Lotus is our reference implementation, and getting more developer attention right now.

（Lotus是我們的參考實現，現在越來越引起開發人員的注意。）

12. So we are going to use SDR till 6 months after Filecoin come on line ? Is NSE (or some other algorithms) be used or added after after Filecoin come on line ?

（那麼我們要在Filecoin上線後的6個月內使用SDR嗎？Filecoin上線後是否使用或添加NSE（或其他一些演算法）？）

We have other constructions in development, NSE and other options. They will be proposed as network upgrades through a FIP (Filecoin Improvement Proposal) after Mainnet launch. We hope to have at least one of these faster and cheaper constructions online within 6-12mo, but the development timeline depends on a lot of different constraints after mainnet launch. Note that new proofs will coexist with SDR, so a new cheaper proof will be optional to miners.

（我們在開發，NSE和其他選項方面還有其他結構。在主網啟動後，將通過FIP（Filecoin改進提案）提出網路升級建議。我們希望在6-12mo內至少有一種更快，更便宜的在線構造，但是開發時間表取決於主網啟動後的許多不同限制。請注意，新的證明將與SDR共存，因此礦工可以選擇使用新的更便宜的證明。）

13. Will the existence of filecoin pool lead to the deviation of centralized storage from the vision of distributed storage?

（Filecoin礦池的存在是否會導致存儲的集中化，從而偏離分散式存儲的願景？）

No – Filecoin creates a decentralized storage network in part by massively decreasing the barrier to entry to becoming a storage provider. Even if there were some large pools, anyone can join the network and provide storage with just a modest hardware purchase, and we expect clients to store their files with many diverse miners.

Also, note that world location matters for mining: many clients will prefer miners in specific regions of the world, so this enables lots of miners to succeed across the world, where there is storage demand.

（不，Filecoin可以部分地通過大大降低成為存儲提供商的准入門檻來創建去中心化的存儲網路。即使有一些大型礦池，任何人都可以加入網路並只需購買少量硬體即可提供存儲，我們希望客戶將其文件存儲在許多不同的礦工中。

另外，請注意，地理位置對挖礦至關重要：許多客戶將更喜歡在世界特定地區的礦工，因此這使許多礦工在存在存儲需求的世界各地都能成功。）

14. Any updates of the security research fellowship? any new critical bugs ? been found/submitted?

（安全研究有任何進展嗎？是否發現/提交了新的嚴重錯誤？）

In the next couple of weeks, there will be a website to view bug submissions, security research fellows, and submit new reports. We also plan to introduce a public bounty program similar to Ethereum』s.

（在接下來的幾周中，將有一個網站可以查看錯誤提交，安全研究人員提交新報告。我們還計劃推出類似於以太坊的公共賞金計劃。）

15. If someone could bring many 'verified client' or reputable business data users on board, any mechanism for rewarding/benifit this activity?

（如果有人可以帶動許多「經過驗證的客戶」或信譽良好的業務數據用戶，那麼有什麼機制可以獎勵/受益於這項活動？）

We anticipate that miners will compete for deals from verified clients, and some partnerships could emerge between miners and reputable users.

（我們預計，礦工將與經過驗證的客戶爭奪交易，並且礦工與信譽良好的用戶之間可能會出現一些合作夥伴關係。）

16. How does a committed capacity sector turn into a sector with real client data? Is it automatically covered with real data when there's a real deal?

（承諾的容量扇區如何變成具有真實客戶數據的扇區？達成交易時，會自動用真實數據覆蓋嗎？）

Committed Capacity sectors are like empty Uber cars on a platform economy. Miners commit capacity to the network when there is unmet supply and upgrade them to sectors with deals when demand arrives to earn additional revenue. For the first iteration of the protocol, we will reuse much of the existing code path. Miners will publish their storage deals, announce to the chain that they are doing an upgrade, and prove that the upgrade has been done successfully.

（承諾產能扇區就像平台經濟上的空Uber汽車。礦工在供應不足時向網路承諾容量，並在需求到來時將其升級為有交易的扇區以賺取額外收入。對於協議的第一次迭代，我們將復用許多現有的代碼路徑。礦工將發布他們的存儲交易，向鏈宣布他們正在進行升級，並證明升級已成功完成。）

17. What do miners have to do to change a committed capacity sector into a "real-data" sector?

（礦工如何將承諾的產能扇區轉變為「真實數據」扇區？）

We are reusing much of the existing code path for this first iteration. Miners will publish storage deals that they will upgrade the CC sector with, announce to the chain that they are doing an upgrade, and prove to the chain that a new sector has been sealed correctly. We expect to evolve and make this cheaper and more attractive over time after Mainnet.

(我們在第一次迭代中復用了許多現有的代碼路徑。礦工將發布存儲交易，與之一起升級承諾容量扇區，並向鏈宣布其正在進行升級，並向鏈證明新扇區已正確密封。我們希望隨著主網的發展，隨著時間的推移，它會變得更便宜，更有吸引力。)

18. Hi, look at this.??How do ordinary people, not geeks, get involved in this work?

（普通人如何參與這項工作？）

You can start from checking out the tutorials from Protoschool: https://proto.school/#/tutorials

Participate in the hackathon and future events of Filecoin Ignite: https://ignite.fil.events/

Check out the different tools to build dapps on Filecoin: https://blog.textile.io/

查看在Filecoin上構建dapp的不同工具：https://blog.textile.io/）

19. What are the standards and conditions of the verifier, is there a selected institution to verify, can you tell us about this situation?

（驗證者的標準和條件是什麼？是否有選定的機構進行驗證，您能告訴我們這種情況嗎？）

There will be several different institutions. We don』t have more updates about Verfiers at this time. We will have more around mid July.

（會有幾個不同的機構。目前，我們沒有關於驗證者的更多更新。我們會在7月中旬左右更新更多信息。）

20. What is the mechanism of verified clients? How to apply to be verified clients?

（驗證客戶的機制是什麼？如何申請經過驗證的客戶？）

Check out this presentation for the basics of Verified Clients and Verifiers: https://youtu.be/q5Vwr0cwQuY?t=920 -- We don』t have more updates about Verfiers at this time. We will update more later in July.

（請查看此演示文稿，以了解已驗證客戶端和驗證程序的基礎知識：https://youtu.be/q5Vwr0cwQuY?t=920-目前我們沒有關於驗證者的更多更新。我們稍後將在7月更新更多信息。）

21. Why not implement the scheme that the white paper says "miners and clients automatically match orders through order books"？Is it because the LIMITS of TPS ?

（為什麼不執行白皮書中所說的「礦工和客戶通過訂單簿自動匹配訂單」的方案？是因為TPS的限制嗎？）

There will be off-chain orderbooks and miner marketplaces -- some are in development now from some teams. They will work mostly off-chain, because TPS on chain is not enough for the volume of usage we expect on Filecoin. These orderbooks build on the basic deal-flow on chain. These orderbooks will arrive in their own development trajectory -- most likely around or soon after mainnet launch.

（將會有鏈下訂單和礦工市場-一些團隊正在開發中。它們將大部分在鏈下工作，因為鏈上的TPS不足以達到我們期望在Filecoin上使用的數量。這些訂單基於鏈上的基本交易流程。這些訂單將以它們自己的發展軌跡出現-最有可能在主網啟動前後。）

22. What's the bot sending deal frequency per miner node/valid deal timeframe? As to maximize to tolerance for different hardware setup?

（機器人在每個礦工節點/有效交易時間範圍內發送交易頻率是多少？為了最大程度地兼容不同的硬體設置？）

The frequency will increase alongside the miner』s rate of adding committed storage. It will be somewhat randomized to simulate real-world behavior.

（頻率會隨著礦工增加承諾存儲的速度而增加。它將在某種程度上隨機化以模擬現實世界的行為。）

23. Can we confirm the mainnet launch time is on track? 20 Jul 2020 to 21 Aug 2020

（我們能否確認主網啟動時間？2020年7月20日至2020年8月21日）

As we said in our roadmap update yesterday (https://filecoin.io/blog/roadmap-update-june-2020/), we』re continuing to make good progress towards mainnet launch, aiming towards the end of our mainnet launch window. However, all dates are still best-effort optimistic estimates - our top priority is to launch a secure and successful network.

（正如我們在昨天的路線圖更新中（https://filecoin.io/blog/roadmap-update-june-2020/）所述，我們將繼續朝著主網啟動取得良好進展，以期結束我們的主網啟動窗口。但是，所有日期仍是儘力而為的樂觀估計-我們的首要任務是建立一個安全、成功的網路。）

24. For the incentive phase, you said a miner has to execute the full sector life cycle and terminate the sectors. What does "terminating" the sectors mean?

（在激勵階段，您說礦工必須執行整個扇區的生命周期並終止這些扇區。 「終止」扇區意味著什麼？）

When a CC sector is added to the chain, it can upgrade to a sector with deals, extend its lifetime, or terminate through either faults or voluntary actions. While we don』t expect this to happen very often on Mainnet, a miner may deem it rational to terminate their promise to the network and their clients but accept a penalty for doing so. We want miners to execute the full sector lifecycle to get a flavor of providing long-term and useful storage on Filecoin.

（將承諾容量的扇區添加到鏈中後，它可以升級到具有交易的扇區，延長其壽命或通過故障或自願行動終止。儘管我們不希望這種情況在主網上經常發生，但礦工可能認為終止對網路及其客戶的承諾是合理的，但會因此受到懲罰。我們希望礦工執行完整的扇區生命周期，以獲得在Filecoin上提供長期有用存儲的體驗。）

25. Does the CC sector still need to be sealed before it upgrades to one with real data ?

(承諾容量部門在升級為具有實際數據的扇區之前是否仍需要密封？)

For the first iteration of the protocol, yes. We have plans to make it cheaper and more economically attractive after Mainnet with no resealing required and other perks.

(對於協議的第一次迭代，是的。我們計劃在使用主網後使其更便宜和更具經濟吸引力，以及無需重新密封等其他好處。)

26. When shall we expected to get the detailed params of the filecoin's Cryptoeconomic？

（我們預計什麼時候可以獲得Filecoin的代幣經濟學的詳細參數？）

We are still finalizing our Cryptoecon parameters and they will continue to evolve. We are looking to solidify more final parameters in late July. Let us know if you have more questions on the structural mechanisms themselves.

（我們仍在最終確定Cryptoecon參數，並且它們將繼續迭代。我們希望在7月下旬鞏固更多最終參數。如果您對結構機制本身還有其他疑問，請告訴我們。）

27. We bought a lot of hard drives, when can they be shipped (China)?

（我們買了很多硬碟，什麼時候可以發貨到中國？）

There are a number of details that are still being finalized between the verified deals construction and the associated cryptoecon parameters.

Our aim is to allow these details to finalize before shipping, but given timelines we』re considering enabling teams to take receipt of these drives before the parameters are set.

（在經過驗證的交易構造和關聯的cryptoecon參數之間，仍有許多細節仍在確定中。

我們的目的是讓這些詳細信息在發貨前最終確定，但是鑒於時間表，我們正在考慮讓團隊在設置參數之前接收這些驅動器。）

28. Will it be cheaper to store data on Filecoin than other centralized cloud services? If yes, when it is anticipated to occur?

（在Filecoin上存儲數據會比其他集中式雲服務便宜嗎？如果是，預計何時發生？）

Filecoin creates a hyper-competitive market for data storage – there will be many miners offering many prices, rather than one fixed price on the network. We expect Filecoin』s permissionless model and low barriers to entry to result in some very efficient operations and low-priced storage, but it』s impossible to say what exact prices will be until the network is live.

（Filecoin為數據存儲創造了一個競爭激烈的市場-網路上將有許多礦工提供很多價格，而不是一個固定價格。我們希望Filecoin的無許可模式和較低的進入壁壘會導致某些非常有效的運營和低價的存儲，但是無法說確切的價格，直到網路正常運行。）

29. What if we lost a sector accidentally, is there any way to fix that?

（如果我們意外丟失了一個扇區，有什麼辦法可以解決？）

If you lost the data itself, then no, there』s no way to recover that, and you will be slashed for it. If the data itself is recoverable, though (say you just missed a Windowed PoSt), then the Recovery process will let you regain the sector.

（如果您丟失了數據本身，那麼將無法恢復它，因此您將因此遭受損失。但是，如果數據本身是可恢復的（例如您剛錯過了Windowed PoSt），那麼恢復過程將使您可以重新獲得該扇區。）

30. What data size is the bot gonna send to miners?

（機器人將發送給礦工的數據量是多少？）

Expect ranges from a few kilobytes up to full 32GiB sectors.

（期望範圍從幾千位元組到完整的32GiB扇區。）

31. 有效數據怎麼在競賽中認定並存儲？

They will not. Verified clients are not part of the testnet incentive competition.

（有效數據不會在測試網被驗證。已驗證用戶不是測試網激勵比賽的一部分。）

32. If the order book is off chain who is going to host it? Wouldnt that fragment the marketplace and liquidity into lots of little venues?

（如果訂單簿是脫鏈的，誰來託管？會不會把市場和流動性分割成很多小場所？）

There will be a small number of different, competing orderbook protocols, similar to how there are different orderbooks for DeFi on Ethereum (eg 0x and others). We think this kind of protocol competition is a good thing that will allow innovation in the design space. We are very excited about what some development teams are working on and can』t wait to see them in action after mainnet launches. If you have some ideas for this, we recommend you try building them!

（將會有少量不同的競爭性訂單簿協議，類似於以太坊上的DeFi的不同訂單簿（例如0x等）。我們認為這種協議競爭是一件好事，它將允許設計領域的創新。我們對某些開發團隊正在從事的工作感到非常興奮，並且迫不及待地希望在主網啟動後看到他們的實際行動。如果您對此有任何想法，建議您嘗試構建它們！）

33. 5PB big miner incentive will be included or excluded in the 4M incentives?

（5PB大礦工獎勵將包括在400萬獎勵中還是排除在外？）

The mechanisms for the incentive competition are here: https://filecoin.io/blog/announcing-testnet-incentives/

（獎勵競爭的機制在這裡：https://filecoin.io/blog/announcing-testnet-incentives/）

34. 7.20的競賽中，4百萬FIL獎勵全部都會被礦工瓜分嗎？你們預期礦工能拿到多少？

你可以在這裡：https://filecoin.io/blog/announcing-testnet-incentives/

了解更多關於測試網激勵的細節。多少Fil會被瓜分是由礦工決定的，你可以加碼更多存儲來解鎖更多獎勵。

35. What』s the minimum time period for the storage contract between the provider and the buyer?

（提供者和購買者之間的存儲合同的最短期限是什麼？）

The minimum duration for a deal is set in the miner』s ask. There』s also a practical limitation, because sectors have a minimum duration (currently one month).

（交易的最短持續時間由礦工的要價設定。還有一個實際的限制，因為扇區的持續時間最短（目前為一個月）。）

36. How are you working to bootstrap the demand side of the marketplace? The Discover program is nice but who is the target market for users and how do you get them？

（您如何引導市場的需求側？Discover計劃很好，但是誰是用戶的目標市場以及如何獲得他們呢？）

In addition to Filecoin Discover, a number of groups are actively building tools and services to support adoption of the Filecoin network with developers and clients. For example, check out the recordings from our Virtual Community Meetup to see updates about Textile Powergate and Starling Storage: https://filecoin.io/blog/filecoin-virtual-community-meetup-recap/ A number of other programs, like Filecoin Ignite, will also contribute additional demand, tooling, and usage.

（除了Filecoin Discover，許多團體正在積極構建工具和服務，以支持開發人員和客戶採用Filecoin網路。 

例如，查看我們的虛擬社區聚會中的記錄，以查看有關Textile Powergate和Starling Storage的更新：https://filecoin.io/blog/filecoin-virtual-community-meetup-recap/其他許多程序，例如Filecoin Ignite，還將貢獻額外的需求，工具和用途。）

37. 經濟參數什麼時候公布？

We are still finalizing our Cryptoecon parameters and they will continue to evolve. We are looking to solidify more final parameters in late July. Let us know if you have more questions on the structural mechanisms themselves.

我們還在確定主網經濟參數而這些參數也會逐步迭代演繹。我們希望在七月底確定接近主網上線的參數。如果有關於經濟結構的問題，歡迎和我們聯繫。

38. 如果礦工大量的投入設備，後期演算法更改對礦工帶來的損失會是怎樣的？

We anticipate two kinds of proof upgrades: (1) Optional Efficiency Upgrades, which are just to add new proof constructions that are cheaper or faster, and (2) Mandatory Security Upgrades, where we discover a problem with an algorithm and have to force the network to move to a new algorithm or a different set of parameters. For (1) Efficiency Upgrades, we expect these upgrades to be optional and coexist and be used only if miners and clients choose to make use of them. We expect 0, 1 or 2 of these per year. -- For (2) Mandatory Security Upgrades, these will come with some sort of transition plan attempting to minimize cost to the network. We don』t expect these, but they may happen.

（我們預計會有兩種證明升級：（1）可選的效率升級，僅用於添加更便宜或更快速的新證明構造；以及（2）強制性安全升級，其中我們發現演算法問題並必須強制網路遷移到新演算法或一組不同的參數。

對於（1）效率升級，我們希望這些升級是可選的並且共存，並且僅在礦工和客戶選擇使用它們時才使用。我們預計每年有0、1或2個。

對於（2）強制性安全升級，這些將帶有某種過渡計劃，試圖將網路成本降至最低。我們不期望發生這些，但是可能會發生。）

39. Does filecoin reward network or main network line machine need fixed IP？

（Filecoin獎勵網路或主網路線機是否需要固定IP？）

For mainnet, you will need a public IP address, but it doesn』t need to be fixed (just accessible).

（對於主網，您將需要一個公共IP地址，但不需要固定（僅需可訪問）。）

40. 如果想參與挖礦，現在建不建議開始購買硬體？購買怎樣的硬體？

While the Filecoin team does not recommend any specific hardware configuration, we did share some setups (https://filecoin.io/blog/announcing-testnet-incentives/#hardware) we』ve used for various types of testing. However, it is overwhelmingly likely that there are more efficient setups, and we strongly encourage miners to test and experiment to find the best combinations.

（儘管Filecoin團隊不推薦購買任何具體硬體配置，但是我們分享了一些我們測試過的不同配置在這裡(https://filecoin.io/blog/announcing-testnet-incentives/#hardware) 。

這些配置大概率可以被進一步優化，我們也推薦礦工測試和優化達到最佳配置組合。）
