Archive nodes

Overview

All Minima nodes have a txpow database and an archive database.

The txpow database contains full blocks, which includes complete information about all transactions. This is limited to the most recent blocks from the unpruned section of the chain - approximately the last 24 hours worth.

The archive database contains the last 2 months of sync blocks, which do not include transaction details but do hold all the MMR proofs for coins spent or created in the block. Sync blocks older than 2 months are not stored unless the node is set up as an archive node.

Archive nodes store all the sync blocks from after the archive node is started, no pruning is done after 2 months.

important

An archive node can only be used to recover users who created their nodes after your archive node was created. If you wish to be able to recover any Minima user, you must perform a chain re-sync from an archive node that holds the entire blockchain since genesis.
