Snapshots

Sync a Filecoin node in minutes, not weeks.

Validating the Filecoin chain from genesis takes about a month. A snapshot is a pre-validated collection of chain state you import to skip straight to a recent head. Stax serves fresh mainnet snapshots every day.

Snapshot hierarchy

Three depths, one format.

Pick the lightest snapshot that covers your use case. Most operators want lightweight; explorers and indexers want full; researchers reach for archival.

Recommended

Lightweight

Recent state without full history. The right choice for syncing a fresh node fast. Smaller, faster, sufficient for most operators.

End height: Recent head
Messages from: head − 2,000
State from: head − 2,000
Cadence: Daily

Heavy

Full

Recent head with deeper message and state history for explorers, indexers and anything querying older state.

End height: Recent head
Messages from: deep history
State from: deep history
Cadence: On request

Historical

Archival

Sparse checkpoints at fixed epoch intervals back to early 2026, for replay and point-in-time state reconstruction.

End height: fixed epochs
Spacing: ~30,000 epochs
Oldest: epoch 5,700,000
Cadence: rolling

Naming

Stax-branded, drop-in compatible.

Snapshots follow a predictable scheme: network, production date, and chain height at the snapshot head. The format is the standard Filecoin .car.zst — only the prefix is ours.

mainnet — the Filecoin network
2026-06-04 — UTC date produced
height_6075840 — chain epoch at head

Quick start

Download, verify, import.

Three steps from a cold box to a syncing node. The latest snapshot is always at the /latest/mainnet/ path.

Watch the sync

After import, the node fetches headers down to your snapshot height, then validates forward to the live head.

lotus sync wait
