Layer 1 / NETWORK PROFILE
Filecoin
FIL CMC #74 in the snapshot
A storage network and programmable blockchain that uses economic commitments and cryptographic proofs to coordinate providers, data storage, and on-chain services.
01 / THE PURPOSE
What is Filecoin for?
Filecoin lets clients arrange storage with providers and makes storage commitments verifiable. Its blockchain records the economic and proof-related state; it is not a system that puts every stored file directly inside every block.
02 / THE ARCHITECTURE
Three questions about the machinery.
How does it agree?
Consensus & securityExpected Consensus selects block producers using storage power backed by proofs. Providers prove replication and continued storage. Fast Finality in Filecoin, or F3, adds a finalization mechanism alongside the existing block-production process.
Where do instructions run?
Execution modelThe Filecoin Virtual Machine runs programmable actors, with the FEVM providing Ethereum-compatible execution. Contracts can coordinate storage-related funding and other on-chain applications, while retrieving a file is a separate service workflow.
What is the token for?
FIL in the systemFIL pays network fees and participates in storage-provider collateral, rewards, and storage economics. An application may use additional payment assets without changing FIL’s role in the underlying network.
03 / THE DESIGN CHOICES
What comes with the design?
Each architecture makes choices about security, performance, coordination, and who can participate.
A valid storage proof is not the same as a guarantee of fast retrieval through a particular gateway.
Storage providers face hardware, collateral, uptime, and proof-generation obligations, which influence participation costs.
Clients still need an appropriate replication, access-control, and retrieval plan for the data they care about.
04 / IN PRACTICE
Follow one use.
An archive stores copies with multiple providers and monitors their commitments. A later download still needs a working retrieval path; the archive’s preservation policy must consider both proof-backed storage and practical access.
