The project provisions, operates, and maintains critical Filecoin infrastructure across both Mainnet and Calibration Network, providing 24/7 availability for services essential to network reliability, developer workflows, and protocol resilience. This includes six bootstrap nodes (three per network), a continuous snapshot service delivering both latest and historical snapshots (diff and lite formats), a public Calibration Network faucet, and a Calibration Network miner.
This infrastructure supports node operators, developers, and protocol participants by ensuring access to core network services while complementing ChainSafe’s open-source Rust Filecoin node implementation, Forest.

To strengthen Filecoin’s resilience, decentralization, and long-term operability by providing reliable, independently operated core infrastructure services that enable developers, node operators, and ecosystem participants to build, validate, and participate without dependency on centralized providers.

Filecoin relies on shared infrastructure that is expensive and operationally complex to maintain, yet critical for healthy network participation. Without reliable bootstrap connectivity, accessible snapshots, testnet funding, and independently operated miners, onboarding becomes harder, recovery slows, operator diversity declines, and dependence shifts toward a small number of large infrastructure providers.
This increases centralization risk, reduces fault tolerance, and limits the ability of developers and independent operators to test, validate, and participate effectively across both Mainnet and Calibration Network.

ChainSafe operates this infrastructure as a long-lived public service under the ProPGF grant, ensuring continuous availability across both networks. Bootstrap nodes improve peer discovery and connectivity, the snapshot service supports fast recovery and historical state access, the public faucet reduces developer friction on Calibration Network, and the calibnet miner provides an independent Curio-based reference implementation outside large pools.
By maintaining these services with operational visibility and reliability monitoring, the project strengthens decentralization, improves service continuity, and provides practical validation feedback to core implementers, tooling maintainers, and ecosystem developers.
