Callisto file system
Callisto File System solves a problem of independent and securely storing an
archive of security audit reports. The main purpose of this file system is to provide an opportunity to upload, store and view security audit reports, independently from any third-party services. At the same time, the Callisto file system enables users to store custom files in a distributed storage maintained by elected Callisto IPFS-host-nodes.
The system can be scaled depending on demand.
Alternative solutions: Filecoin, Maidsafe, Siacoin, and Storj Filecoin is a decentralized storage network created by the team behind IPFS for the purpose of incentivising the storage of files on IPFS. This protocol creates a
blockchain that utilizes the latest advancements in cryptographic proofs to generate trustless proof-of-storage and proof-of-replication. The protocol then incentivises individuals to run auditors that spot-check storage providers. Filecoin is the currency that storage providers are paid when someone wishes to store or fetch a file from the network. The underlying idea is that there are vast quantities of unused storage sitting on home computers and servers around the globe. Filecoin aims to enable the owners of this unused storage to monetize it, while eliminating any need for 3rd parties to trust the storage providers, or vice versa.
The model adopted by Filecoin is similar to other decentralized storage
solutions such as Maidsafe, Storj, and Siacoin. They all attempt to collect
micropayments for both the storage and retrieval of data, and they all create their own dedicated currency. Furthermore, all of these products target home computer storage providers renting out space located behind slow internet connections. Lastly, they all require users to continually purchase cryptocurrency to pay for storage and bandwidth. This means the files may not be available for the general public to access for free via their browser.
The cost of storage and bandwidth on these networks may be higher than that offered by cloud service providers such as Amazon S3. For example, at the time of this writing, Storj charges $0.05 per GB of download whereas Amazon charges $0.01 per GB downloaded. Storj charges $0.015 per GB per month whereas Amazon charges $0.0125 per GB per month for infrequently accessed storage (Glacier). It is not clear that the designs of Filecoin, Maidsafe, Siacoin or Storj scale up to many users and many accesses. As the number of users and files grows, the number of recurring payments will also grow. This will place increasing stress on their single-threaded blockchains as the base transaction load grows just to maintain the status quo. Users wanting to store files will need to set up their own server to
make automatic crypto payments or they will have to log in every month to do it manually. The overhead of zero-knowledge proofs and spot checks consume bandwidth and CPU resources whose cost may be greater than the actual cost of the storage and bandwidth being managed.
I continue to collect project information for a great article and review. If the author of the post, I use these thoughts for your article! Thank you for the information!
