您怎么在Filecoin的去中心化存储网络上避免信息遗失的发生?

  • Filecoin专为高冗余,高可用性和高地理复制的存储而设计。没有人能够应付数据丢失的所有情况,但我们可以通过鼓励高度复制,主动修复损坏以及使矿工失败成本高昂来大幅提高成功的可能性。

    Filecoin以冗余方式将数据存储在多个存储矿工上。如果其中一个矿工丢失了文件,他们就会失去其抵押品(作为未能履行交易的支付费用),并且一名新矿工会被自动雇佣来存储该文件的另一个副本。通过这种方式,Filecoin网络有望自我修复,并随着时间的推移修复损坏。这在某些方面与今天的专业云存储提供商的工作方式相似,但多了一个可以在多个存储提供商之间的修复功能。

    在Filecoin网络上,客户可以调整其数据复制的次数,也称为复制因子(或擦除编码),以更高价格来实现更高级别的数据冗余和安全性。复制默认值将被仔细选择以提升安全存储能力和降低数据丢失的风险。客户可以调整这些默认值,以不同的成本实现更高(或更低)的冗余和安全级别。

    此外,我们预计声誉系统的产生。我们希望客户节点能够运行软件来了解存储矿工过去工作表现并有望雇佣到更可靠的矿工。

    If there does exist such a thing, I cannot find it.

    I don't believe there is

    zenground0 [7 hours ago]
    tho maybe phritz has some "refactor the vm" issues that are relevant

    I assert to you that we must create an InitActor in order for CreateStorageMiner conform to the specification.

    Why [7 hours ago]
    I’ll take things I don’t disagree with for $400 Alex

    zenground0 [7 hours ago]
    Agreement all around. However this is one of those changes that is pretty orthogonal to getting the storage protocol to work and something we can already do. We need to track it but I see it as a secondary priority to (for example) getting faults or arbitrating deals working.

    Thanks @zenground0, I concur. Init actor is in our high-level backlog, but I'm not surprised there's no issue yet. Is it reasonable to draw our boundary there for now?

    Does there already exist a story which addresses the need to create an InitActor?

    I believe that a solution to this problem is that the rust-fil-proofs CircleCI build needs to be modified to link the libfilecoin_proofs.a archive file to a dummy C program using the same pkg-config file which go-filecoin uses.

    The libfilecoin_proofs.a file has a few dynamic dependencies - things we can't link in statically, like glibc - and the linker flags have to been updated manually. Unfortunately, rust-fil-proofs CircleCI build doesn't try to link the libfilecoin_proofs.a file, so we don't know when we get the linker flags wrong until we've already updated the go-filecoin submodule SHA.
