Running a Mina Archive Node

This article is published on Medium.

Mina is a succinct blockchain, and as a result, consensus nodes only store the recent history of the chain before discarding it (the last k blocks, currently 290).

Examples include block explorers and wallets. To solve this problem, users may optionally run an archive node that stores a summary of each block seen in a Postgres database.
