为什么Filecoin选择用“存储证明” (Proof-of-Storage),而不是“权益证明”(Proof-of-Stake)?


  • administrators

    Filecoin使用存储证明 (Proof-of-Storage)共识协议,因为它简单,能协调利益,并促使矿工以有竞争力的价格提供真实的新增的存储容量。 在开发一种我们称之为复制证据(Proof-of-Replication)的新型存储证明(Proof-of-Storage) 时,我们将使矿工的存储设备包含有用的数据,使其成为网络的一个宝贵资源。 权益证明是我们正密切关注的一个很有意思的研究领域。

    It shouldn't be a significant centralization risk. The costs of buying your own GPUs or starting a new outsourced proving service will be pretty low. Even if many people decide to use third-party provers, there should be a competitive and well-distributed market.

    We're working really hard to reduce sealing and proving costs. We really want to support smaller miners, but not at the cost of security. It's always possible to make things faster and cheaper through later optimizations, but it's hard to make things more secure.

    Why here! We will make this customizable, right now in lotus its set to some pretty big value. We might even make a special mode for 'filler storage', storage youre adding just for power that doesnt have any real deals associated with it.

    Details around faults and recovery can be found in the spec (https://github.com/filecoin-project/specs/). The protocol will accommodate both realistic operational needs for good miners and service providers, while maintaining the security of the protocol and Quality of Service for Clients' data. Having a data storage service offline is not good for Clients, and are not good for the service. At the same time, temporary power failures happen, and the protocol needs to accommodate them to some extent. As we get closer to mainnet, we will set cryptoecon parameters and policies, and we will explain them clearly for everyone.
