久等了!Filecoin 测试网还有 13 小时上线|点滴资讯

喜大普奔!Filecoin 官方宣布:12 月 11 日测试网上线,2020 年第一季度主网上线,距离测试网上线还不到一天,让我们来看看官方的最新消息。

久等了!Filecoin 测试网还有 13 小时上线|点滴资讯

成为 Filecoin 矿工为社区成员提供了一个机会,可以帮助他们存储和保留对人类最重要信息的访问。通过提供网络安全性和基础架构,Filecoin 矿工可以帮助构建更开放,更具弹性和可信赖的 Internet。

Filecoin 挖掘是一个新机会,它可以通过庞大的网络为客户提供数据存储和检索服务来赚取收入。矿工通过在 Filecoin 网络上存储和检索客户信息来赚取费用。

Filecoin 矿工存储的客户端数据越多,矿工的存储能力就越大。网络上更多的存储能力意味着特定的矿工更有可能生成区块并赢得区块奖励。矿工可以选择是否参与存储功率共识,存储挖掘和 / 或检索挖掘。我们预计许多矿工将在这些类别中提供针对性的专业服务。

您放置在 Filecoin 网络上的采矿硬件除了提供网络安全性和批量生产外,还将为客户端提供有用的数据存储服务。这将 Filecoin 网络上的挖掘与传统的工作量证明网络区分开来。

重新分配多余的存储容量以运行 Filecoin 节点会将您曾经的潜在存储资产转变为安全的存储服务。矿工提供的区块生产,存储和检索服务对于 Filecoin 的生态系统而言具有不可估量的价值。通过将许多矿工和存储提供商聚集在一个分散的网络中,Filecoin 联合了有史以来第一个用于租用数据存储的算法市场中的存储提供商。

Becoming a Filecoin miner is an opportunity for community members to help store and preserve access to humanity’s most important information. By providing network security and infrastructure, Filecoin miners help build a more open, resilient, and trustworthy Internet.

Filecoin mining is a novel opportunity to earn revenue from providing data storage and retrieval services to clients across a vast network. Miners earn fees by storing and retrieving client information on the Filecoin network. The more client data a Filecoin miner stores, the more that miner’s storage power grows. More storage power on the network means it is more likely a specific miner can generate blocks and win block rewards. Miners can choose whether to participate in storage power consensus, storage mining, and/or retrieval mining. We anticipate many miners will provide focused, specialized services within these categories.

The mining hardware you put on the Filecoin network will provide useful data storage services for clients in addition to providing network security and block production. This differentiates mining on the Filecoin network from traditional Proof-of-Work networks.

Reallocating excess storage capacity to run Filecoin nodes turns your once latent storage assets into a secure storage service. The block production, storage and retrieval services that miners provide are incredibly valuable to Filecoin’s ecosystem. By bringing many miners and storage providers together in a decentralized network, Filecoin unites storage providers in the first-ever algorithmic marketplace for hiring data storage.

如何加入 Filecoin 测试网

如何加入测试网,让我们一起来学习!

要加入即将到来的 Filecoin testnet,你需要合适的硬件和安装和设置 Lotus 实施。有关安装和设置的更多信息,请参阅 Lotus docs (https://docs.lotu.sh/)。

接下来,您需要抵押 Filecoin 代币作为建立矿工的抵押。“抵押抵押品”是作为存储矿工加入网络所需的初始文件币数量。随着时间的推移,矿工进入与客户的每个额外存储交易时,还必须存入更多的“交易抵押品”。抵押品已部署在网络上,以确保矿工的行为正常,并以 FIL 令牌计价。有关抵押品的详细信息将在未来几周内在 Filecoin 规范中最终确定。在测试网期间,您可以从我们的网络水龙头取回测试文件币,用作开始挖掘的抵押。测试文件币没有任何价值-正式文件币令牌将在主网启动后才能发布。

To join the upcoming Filecoin testnet, you’ll need appropriate hardware and to install and set up the lotus implementation. For more information about installation and setup, please see the lotus docs.

Next, you’ll need to pledge filecoin tokens as collateral to set up your miner. “Pledge collateral” is an initial amount of filecoin that is required to join the network as a storage miner. A miner must also deposit more “deal collateral” over time as it enters each additional storage deal with clients. Collateral is deployed on the network to ensure miners behave appropriately, and it is denominated in FIL tokens. Details about collateral will be finalized in the Filecoin spec over the coming weeks. During testnet, you can retrieve test filecoin from our network faucet to use as collateral to start mining. Test filecoin do not have any value – the official filecoin tokens will not be released until mainnet launch.

协议实验室的标准硬件测试配置

(请仔细阅读)

注意:本节描述了协议实验室团队用于在 Lotus 实现上测试 Filecoin 存储挖掘的标准测试配置。无法保证此测试配置将适用于主网启动时的 Filecoin 存储挖掘。如果您需要购买新硬件以加入 Filecoin 测试网,建议您购买的硬件数量不要超过测试所需的数量。

我们的标准测试配置是 Filecoin testnet 挖掘的众多可能性之一。我们希望测试网矿工能够找到其他硬件组合,其中一些可能比下面描述的测试配置更有效。如果您使用其他硬件配置来运行 Lotus,请运行 Lotus 基准测试工具,并将结果发布到此线程中。

开采区块所需的扇区大小和最低保证存储量是影响硬件决策的两个非常重要的 Filecoin 测试网参数。我们将在测试网期间继续完善这些参数(以及其他证明参数)。因此,我们针对 Filecoin 主网的标准测试配置可能会更改。

扇区大小:如果您选择购买硬件以在 Filecoin 测试网上进行测试,我们建议您购买支持 Seal 32GiB 扇区的计算硬件。测试网将暂时支持 1GiB“测试部门”,以便矿工可以轻松地加入网络。这样小的扇区大小对于主网来说是不现实的。在测试网启动后,我们将进行一次分叉升级,以停止对 1GiB“测试部门”的支持,并将在我们的博客上宣布升级的时间和机制。

矿工规模:要有资格在测试网期间进行区块挖掘(不仅仅是接受存储交易),矿工必须保证至少 512GiB 的磁盘存储空间。Filecoin 主网的这一要求可能会增加。如果您只想参与存储交易,则可以以较少的存储空间加入网络。但是,如果您当前对网络的认捐额不足 512GiB,那么您经过验证的存储将不会计入网络的总功率,也将无法使您获得大量奖励。

下面是我们测试过的用于 Seal Lotus 上 32GiB 扇区的配置。该配置基于 Filecoin 挖掘过程中所需的步骤。我们在标准测试配置中进行了与计算能力相关的特定权衡(即,我们为 GPU 分配资源而不是更多的 CPU 能力)。可以使用其他配置在 testnet 上进行挖掘,但是由于我们尚未测试所有配置,因此在本文中我们将不讨论其可行性或性能。

小编注:目前如果选用 32G 扇区大小的话,至少需要 64—96G 的内存,同时需要 512G 的硬盘空间以上,希望广大矿工早做准备!

CAUTION: This section describes the standard testing configuration the Protocol Labs team has used to test Filecoin storage mining on the lotus implementation. There is no guarantee this testing configuration will be suitable for Filecoin storage mining at mainnet launch. If you need to buy new hardware to join the Filecoin testnet, we recommend to buy no more hardware than you require for testing.

Our standard testing configuration is one of many possibilities for Filecoin testnet mining. We expect testnet miners to find additional hardware combinations, some of which might be more efficient than the testing configuration described below. If you’re running lotus with alternate hardware configurations, please run the lotus benchmarking tool and post your results in this thread.

Sector sizes and minimum pledged storage required to mine blocks are two very important Filecoin testnet parameters that impact hardware decisions. We will continue to refine these parameters (and other proofs parameters) during testnet. Because of this, our standard testing configuration for Filecoin mainnet may change.

Sector Sizes: If you choose to purchase hardware to test on the Filecoin testnet, we recommend you buy computational hardware that will support sealing 32GiB sectors. Testnet will temporarily support 1GiB “test-sectors” so miners can easily on-board to the network. This small sector size is not realistic for mainnet. We will perform a fork upgrade to discontinue support for 1GiB “test-sectors” after testnet launch, and will announce the timing and mechanics of the upgrade on our blog.

Miner Size: To be eligible for block mining during testnet (not just accepting storage deals), a miner must pledge at least 512GiB of disk storage. This requirement will likely increase for Filecoin mainnet. If you’re only interested in participating in storage deals, you can join the network with less storage. However, your proven storage will not count towards total network power and will not enable you to earn block rewards if you currently have under 512GiB pledged to the network.

Below is the configuration we have tested for sealing 32GiB sectors on lotus. The configuration is based on the steps required in the Filecoin mining process. We made specific trade-offs related to computational power in our standard testing configuration (i.e., we allocate resources for GPUs instead of more CPU power). It is possible to mine on testnet with other configurations, but since we haven’t tested all of them, we will not cover their viability or performance in this post.

复制证明(“ PoRep”或“Seal”)

我们正在测试功能强大的 CPU (至少具有 8 个内核),以便在 PoRep 期间复制客户端数据。强大的 CPU 使矿工可以更快地处理数据并更快地生成 PoRep,从而在网络上获得能量。

复制过程利用快速磁盘将数据从内存卸载到磁盘上。为此,我们已经测试了 SSD (512GB),该 SSD 可以用作大型缓存,以存储 Seal 的传输中扇区(在 PoRep 的预提交和提交阶段),并在 Seal 过程中进行缓存。

我们的标准配置还可以在大量 RAM (128GB)下运行。需要 RAM 来计算内存中的数据复制,当前与扇区大小有 2-3 倍的关系。我们设计用于在 PoRep 和 PoSt 的 SNARK 生成过程中运行的电路非常大,并且会消耗大量 RAM。这些大型电路最大程度地减少了 SNARK 证明输出的占用空间,以实现高效的链上提交。

我们还使用强大的 GPU 功能以更省时,更经济的方式生成 SNARK。在每个 Seal 副本的 PoRep 证明上生成 SNARK,并将 SNARK 输出提交到链中。我们特别注意到 Lotus 实现是为 NVIDIA 制造的 GPU 芯片设计的,但是,我们预计将来还会有其他制造商的支持卡。随着我们继续调整证明参数,我们期望主网电路比测试网电路需要更多的计算能力。

我们在测试中观察到,让多个“Seal 设备”在一个存储范围内工作可能比在单个计算机上运行整个 Filecoin 挖掘过程(Seal 和 PoSt)效率更高。这使矿工可以一次高效地运行多个流程。

有关复制证明过程如何与挖掘硬件相关的更多信息,请参见下面的图:

We’re testing with a powerful CPU (with at least 8 cores) to replicate client data during PoRep. A powerful CPU allows a miner to process data faster and generate PoReps more quickly to gain power on the network.

The replication process utilizes fast disks for offloading data from memory onto disk. For this we’ve tested with SSDs (512GB) that function as a large cache to store unsealed sectors-in-transit (during the pre-commit and commit phases of PoRep) and to cache during the sealing process.

Our standard configuration also runs with a large amount of RAM (128GB). RAM is needed to compute data replication in memory, and currently has a 2-3x relationship to sector size. The circuits we designed to run during SNARK generation in both PoRep and PoSt are very large and will consume a significant amount of RAM. These large circuits minimize the footprint of the SNARK output of proofs for efficient on-chain submission.

We also use significant GPU power to generate SNARKs in a more time-efficient and cost-effective way. SNARKs are generated on PoRep proofs of each sealed replica and the SNARK output is submitted to the chain. We specifically note the lotus implementation is designed for NVIDIA-manufactured GPU chips, however, we anticipate supporting cards from other manufacturers in the future. As we continue to fine-tune our proofs parameters, we expect mainnet circuits to require more computational power than testnet circuits.

We observed in our testing that it can be more efficient to have multiple “sealing machines” working across a range of storage instead of running the entire set of Filecoin mining processes on a single machine (sealing and PoSt). This allows a miner to efficiently run multiple processes at a time.

时空证明(“ PoSt”)

我们的测试配置考虑了存储开销–我们目前估计开销是承诺存储的 2 倍,但是对于主网来说可能有所变化。我们目前在 Seal 存储区的磁盘存储中运行着约 1.5TB 的存储空间,但我们认为,有更有效的方法来配置 Seal 存储区以减少开销。我们还测试了对 Seal 扇区的快速并行磁盘访问,以生成票证来潜在赢得 ElectionPost 中块奖励的选举票。

当运行后期处理,我们目前的测试配置存储 Seal 部门在硬盘上,不断操作(24 / 7)由于频繁读取提交帖子。

仅当矿工在给定时期内因赢得大块奖励而赢得了选举票时,才在选举时空(“ ElectionPoSt”)中运行 SNARK 。每当矿工赢得选举票时,我们的配置就使用 GPU 的功能来计算 PoSt SNARK 的输出结果,准确计算出每个纪元周期(约 20 秒)内的 PoSt SNARK。

PoSt 所需的 GPU 功能在很大程度上取决于矿工在任何给定时期拥有多少张获胜选举票,这与他们在网络中的存储比例有关。

我们还建议使用较低延迟的网络连接来按时提交 PoSt。如果矿工多次未能按时提交 PoSt,则可能导致赢得较少的区块奖励,并增加被削减的风险。

有关与采矿硬件相关的 ElectionPoSt 流程的更多信息,请参见下图:

Our test configuration accounts for storage overhead – we currently estimate overhead as 2x pledged storage, but this could change for mainnet. We’re currently running ~1.5TB in disk storage for sealed sectors, but we believe there are more efficient ways to configure sealed storage to reduce overhead. We’re also testing with fast and parallelized disk access to sealed sectors for generating tickets to potentially win election tickets for block rewards in ElectionPost.

When running PoSt processes, our current testing configuration stores sealed sectors on hard disks that continually operate (24⁄7) due to frequent reads for submitting PoSt.

SNARKs are run during Election Proof-of-Spacetime (“ElectionPoSt”) only if a miner has winning election tickets for earning block rewards during a given epoch period. Our configuration uses GPU power to compute PoSt SNARKs output well within (~20 seconds) each epoch period each time our miner wins an election ticket. GPU power needed for PoSt largely depends on how many winning election tickets a miner has during any given epoch, which is related to their proportion of storage in the network.

We also suggest a relatively low latency network connection to submit PoSt on time. If a miner fails to submit PoSt on time many times, it could lead to winning fewer block rewards and increase the risk of being slashed.

For more information about the ElectionPoSt process relates to mining hardware, see our diagram below:

Filecoin 挖掘不是工作量证明 GPU 挖掘

请记住,Filecoin 挖矿基于存储能力共识:在网络上拥有更多功能(经过验证的存储)与赢得更多区块奖励直接相关。 矿工在网络上的电量与矿工在网络上存储的数量成线性关系,而不是与矿机运行的 GPU 数量成线性关系。相比之下,在工作量证明 GPU 挖掘中,矿工必须以 GPU 的能力进行竞争才能赢得区块奖励。在 Filecoin 挖掘中,矿工在存储能力共识而非 GPU 能力上竞争。矿工只有在赢得选举票时才在 ElectionPoSt 中使用 GPU。赢得权力的最佳和最便宜的方法是向 Filecoin 网络添加更多有用的存储。

如果您是较小的矿工,担心 GPU 的成本,请放心,我们正在努力使矿工将 SNARK 计算安全地外包给第三方服务提供商。

小编注:点对点以帮我们的小矿工外包算力,防止攻击,保证挖矿安全。

现在您已经了解了我们,准备将其投入使用!您将有机会很快加入 Lotus 测试网。

Remember, Filecoin mining is based on storage power consensus: having more power on the network (proven storage) is directly related to winning more block rewards. The amount of a miner’s power on the network is linear with respect to the amount of storage the miner puts on the network, not the amount of GPUs it runs. By comparison, in Proof-of-Work GPU mining, a miner must compete on GPU power to win block rewards. In Filecoin mining, a miner competes on storage power consensus and not GPU power. Miners use GPUs during ElectionPoSt only if they have winning election ticket. The best and cheapest way to gain power is by adding more useful storage to the Filecoin network.

If you’re a smaller miner worried about the cost of GPUs, rest assured that we’re working to enable miners to securely outsource SNARK computation to third party service providers.

Now that you know about the gear, get ready to put it to work! You’ll have the opportunity to join the lotus testnet soon.
