Acquiring historical event data
When running an ABCI events database for Penumbra, node operators face a bootstrapping problem:
applications will require access to all historical events, but a given node can only emit
events for blocks greater than h, where h is the height at which the node joined the network.
The penumbra-reindexer (opens in a new tab) tool exists to support node operators
who require historical event data. Please see the README in that repository for details on using the tool.
Finding node state archives
In order to use the penumbra-reindexer, node operators must obtain historical archives for node state,
so that the reindexer can replay those blocks and emit the relevant ABCI events. Node operators are
invited to rifle through archive available via:

If your team maintains Penumbra archives, please submit a pull request to add it to this guide (opens in a new tab).
