Crust Network has a clear positioning:
Incentive layer for IPFS Storage proof layer
IPFS enables content-addressed file retrieval, free from centralized servers.
Crust uses MPoW (Meaningful Proof of Work) to verify that nodes are actually storing the data, and GPoS (Guaranteed Proof of Stake) to bind staking quotas to storage resources.
IPFS handles addressing, Crust ensures persistence. Together, they form a truly usable decentralized storage solution.
