我们基于IPFS自主研发的可信去中心化计算公链，我们在中国有上万家中小企业客户。我们未来会将计算业务和IPFS技术，推向这些企业客户。希望未来我们能够有深度的合作。
Alita提供的大数据的计算业务是通用计算引擎,不像 SETIOHome
Folding@Home那样限定单一的项目,因此无法单纯用结果的验证来确定矿
工是否诚实地提供计算资源。因为任何用户的bug、语法、上游数据变动、
版本等都会造成结果发生变化,而且很多计算任务由于数据的变化不具有幂
等性。所以 Alita并没有通过结果验证确定工作证明,而是提供了PoTA( Proof
of Task Accomplishment),利用内存、CPU、存储、带宽(VCU)的占用时
间以及任务代码和输入数据来签发工作证明。
Alta的基础存储pS利用了IPFS。iPFS是一种协议,而不是一套完整
的文件系统。我们利用这种协议和组网,完成了存储副本、分片、寻址、安
全等组成存储集群,更适合于分布式计算任务的读取。
大数据的计算比较特殊,无法用结果衡量资源消耗真实性。任何用户的
bug、语法、程序包依赖、版本等都会造成结果不符合预期,而且很多计算
任务由于数据的变化不具有幂等性。所以Aita并没有通过结果验证确定工
作证明,而是提供了PoTA证明,利用可验证外包计算的算法,根据内存
CPU、存储(VCU)的占用时间以及任务代码和输入数据来签发工作证明。

Alita's big data computing service is a general-purpose computing engine,which does not limit to a single project like SETIOHomeFolding@Home. Therefore,it is impossible to determine whether miners are honest in providing computing resources by simply verifying the results. Because any user's bug,syntax,upstream data changes,and version will cause changes in the results,and many computing tasks are not idempotent due to data changes. So,Alita does not confirm the work certificate through the result verification but provide PoTA (Proof of Task Accomplishment),which uses the occupied time of memory CPU,storage and bandwidth (VCU),and task code and input data to issue work certificate. Alta's basic storage pS utilizes IPFS which is a protocol,not a complete file system. Using this protocol and networking,we have completed the storage cluster composed of storage copy,fragmentation,addressing,and security,which is more suitable for reading distributed computing tasks. The big data computing is quite special,and you can't use results to measure the authenticity of resource consumption. Any user's bug,syntax,package dependency,and version will cause the results to be inconsistent with expectations,and many computing tasks are not idempotent due to data changes. Therefore,Aita doesn't confirm the work certificate through the result verification,but provide PoTA certificate,and issue the work certificate according to the occupied time of memory CPU and storage (VCU),and task code and input data.

Thanks you for your interest in Gravity! Please allow me to introduce Gravity for you.

 

Here are more details on Gravity:

 

Gravity is decentralized data computing and exchange engine.

 

Gravity leverages user’s idle computing resources and organizes them into a massive and inexpensive cloud computing infrastructure.

 

Many companies could deploy a data service based on the computing infrastructure.

 

Data Service provides secure access to data that are too detailed, sensitive or confidential to be made available under the data protection law like GDPR.

 

Gravity is also attempts to Trusted Execution Environments (TEEs) on ARM-based systems , using the Trust Zone technology.

 

The main persons in Gravity are Providers and Users. Providers include Customer side ( eg. ARM mobile phones/ARM smart devices ) and Business side ( eg. ARM GPU hardware/ARM storage mining hardware ). Users is who that companies require inexpensive computing and require trusted data exchange.

 

Founders are core members as the early aliyun, and he has wealth of experience about building computing platforms、data application and exchange business. And Gravity core team members are the heads of storage and computing systems development come from first-class companies , including ali、Didi、Xiaomi and EMC.

Because Ethereum brought smart contracts, so that the rapid development of the entire blockchain ecology, but the rapid development of the same time, the size of the block, can not carry more application scenarios.
The emergence of FileCoin brings a turning point for the issue of blockchain storage. Whether or not Dapp can do more is likely to be affected by storage size. If you have storage support, social, short video and other multimedia applications will be able to set the scene.
On the other hand, data now resides on the central server, but does not belong to the user itself, user privacy is ruthlessly stolen. This is an Internet era, this is a streak in the eyes of Internet giants age. It is time to return the data ownership to the user, the user himself is the privacy control.
FileCoin network is strong, is that his network nodes are scattered and numerous, we need miners to support the network. Like miners, our miners spread the fire globally, and the FileCoin network becomes even more powerful as long as one of our regions receives our fire. We are not just miners, we are more burdened with our mission.
FileCoinClub is everyone's harbor, where we learn from each other and grow each other.
