Reading this comparison between IPFS and Swarm, I came across this section:
Filecoin is a sister project of IPFS, it adds an incentivisation layer to IPFS and relies on its own altchain. Proof of retrievability "mining" on the filecoin blockchain is a scheme providing ongoing compensation to storers for preserving content. Random audits as part of the proof of work task are responded to with proof of retrievability and the winning miners get compensated accordingly. Such a system has inherent limitations: IPFS can only implement positive incentives and relies on collective responsibilty.
But what is the problem with
only implement positive incentives and relies on collective responsibility? Is there something that Swarm's incentivisation system does that Filecoin/Storj does not?
