We plan to implement a decentralized storage at Callisto Network. I was researching SWARM for long enough. I like its main idea, but it has some problems that could not be solved: for example an issue of microtransactions. There is no solution for this problem unless you have free transactions. And transactions are not free at Callisto.
Explain, please .

What is not clear here? Refused from one way to solve the problem in favor of another. Or are you interested in what SWARM is?
As far as I know, SWARM is a mobile application for different platforms that allows you to share your location. "The introduction of a decentralized storage facility into the Callisto network." What will it give? "
Swarm is a distributed storage platform and content distribution service, a native base layer service of the ethereum web3 stack. The primary objective of Swarm is to provide a sufficiently decentralized and redundant store of Ethereums public record, in particular to store and distribute dapp code and data as well as blockchain data. From an economic point of view, it allows participants to efficiently pool their storage and bandwidth resources in order to provide these services to all participants of the network, all while being incentivised by Ethereum.
