ChainSafe currently operates:

• Mainnet and Calibnet bootnodes
• Calibnet faucet for tFIL and datacap
• Mainnet and Calibnet snapshot service

All of these services are indispensable to the public Filecoin infrastructure and in effect everyone building on top of it.

Calibnet faucet for tFIL and datacap

The faucet tFIL and test datacap faucet, allowing anyone to build and test against the calibration network free of charge before moving to mainnet. We have recently improved the rate limiting features of the faucet to address abuse issues. We also handle manual allocations for larger requests on an adhoc basis.

Mainnet and Calibnet bootnodes

We operate multiple bootstrap nodes that act as the default entrypoint for nodes joining the network:

• 3 mainnet bootstrap nodes
• 4 calibration network bootstrap nodes

Snapshot Service

Since the last RetroPGF we have taken responsibility for and rebuilt the snapshot service initiated and powered by Forest. This is the default snapshot service used by a majority of node on the network.

General Monitoring and Responsiveness

The team has been supporting the development of distributed monitoring and alerting practices to support the network following the nucleation of Protocol Labs, in addition to maintaining internal monitoring and on-call responsiveness.

(Disclosure: ChainSafe receives funding from Protocol Labs to cover a portion of the costs of operating these services. This is done close to cost, with the intent of furthering our involvement in the ecosystem).
