	// contains filtered or unexported fields
}

BaseApp reflects the ABCI application implementation.

	name string, logger log.Logger, db dbm.DB, txDecoder sdk.TxDecoder, options ...func(*BaseApp),

Regardless of tx execution outcome, the ResponseCheckTx will contain relevant gas execution context.

func (*BaseApp) GetBlockRetentionHeight 

func (app *BaseApp) GetBlockRetentionHeight(commitHeight int64) int64

GetBlockRetentionHeight returns the height for which all blocks below this height are pruned from Tendermint. Given a commitment height and a non-zero local minRetainBlocks configuration, the retentionHeight is the smallest height that satisfies:

- Unbonding (safety threshold) time: The block interval in which validators can be economically punished for misbehavior. Blocks in this interval must be auditable e.g. by the light client.

- Logical store snapshot interval: The block interval at which the underlying logical store database is persisted to disk, e.g. every 10000 heights. Blocks since the last IAVL snapshot must be available for replay on application restart.

- State sync snapshots: Blocks since the oldest available snapshot must be available for state sync nodes to catch up (oldest because a node may be restoring an old snapshot while a new snapshot was taken).

- Local (minRetainBlocks) config: Archive nodes may want to retain more or all blocks, e.g. via a local config option min-retain-blocks. There may also be a need to vary retention for other nodes, e.g. sentry nodes which do not need historical blocks.
