Terra is a Proof of stake chain and can also be used as a Smart contract platform. Terra protocol aims to create a stable priced currency by adopting an elastic monetary policy. Terra is supported by a basket of fiat-pegged, seigniorage share style stable coins which are algorithmically stabilized by its native crypto asset, Luna.
The Terra table schemas build on the concepts laid out in Flipside's event data model. Terra tables are available in Velocity as the terra schema. The tables are built based on the terra message, transactions and transition information.
At Flipside database, for Terra, there are two types of tables, one is the Raw Tables and the other one is the Terra Base Tables, clicking the following link to see more details about the tables.
