With the rosetta queries for the block at a particular blockheight, one extra transactions i am getting at the 0th index but that is not present in the explorer?
Is that a garbage transaction?
And is there any more explorer for kava present other than mintscan?

There can be up to two "extra" transactions in a block returned by rosetta. Cosmos blockchains support begin and end block functionalities, which allows balances to change before and after transactions are processed in a block.

Rosetta on the other hand has no concept of balance tracking outside of transactions.

Therefore this rosetta implementation, as well as the one included in cosmos-sdk, adds a transaction to represent balance changes in the begin block and another transaction to represent balances in an end block.

If we look at a block like 2208900, it has no transactions but rosetta reports a single transaction to represent the balance changes in the begin block.

These extra transactions are prefixed with either 0x00 (begin block) or 0x01 (end block) and use the block hash as the suffix.

The hash of block 2208900 is 7AFC8ACE45FE7872944F92C17A160ACB7589C3DDDDA0E15943009DA014340D0A and the transaction hash representing the begin blocker is 007AFC8ACE45FE7872944F92C17A160ACB7589C3DDDDA0E15943009DA014340D0A. If the block had any end block balance changes, a transaction with hash ``017AFC8ACE45FE7872944F92C17A160ACB7589C3DDDDA0E15943009DA014340D0A` would have been included.
