| Table | Key | Value | Description |
|-------------------|----------------------|--------------------|-------------|
| `BlockBlobs` | BlockHeight | `StorableVec<u8>` | Maps a block's height to a serialized byte form of a block
| `BlockHeights` | BlockHash | BlockHeight | Maps a block's hash to its height
| `BlockInfos` | BlockHeight | `BlockInfo` | Contains metadata of all blocks
| `KeyImages` | KeyImage | () | This table is a set with no value, it stores transaction key images
| `NumOutputs` | Amount | u64 | Maps an output's amount to the number of outputs with that amount
| `Outputs` | `PreRctOutputId` | `Output` | This table contains legacy CryptoNote outputs which have clear amounts. This table will not contain an output with 0 amount.
| `PrunedTxBlobs` | TxId | `StorableVec<u8>` | Contains pruned transaction blobs (even if the database is not pruned)
| `PrunableTxBlobs` | TxId | `StorableVec<u8>` | Contains the prunable part of a transaction
| `PrunableHashes` | TxId | PrunableHash | Contains the hash of the prunable part of a transaction
| `RctOutputs` | AmountIndex | `RctOutput` | Contains RingCT outputs mapped from their global RCT index
| `TxBlobs` | TxId | `StorableVec<u8>` | Serialized transaction blobs (bytes)
| `TxIds` | TxHash | TxId | Maps a transaction's hash to its index/ID
| `TxHeights` | TxId | BlockHeight | Maps a transaction's ID to the height of the block it comes from
| `TxOutputs` | TxId | `StorableVec<u64>` | Gives the amount indices of a transaction's outputs
| `TxUnlockTime` | TxId | UnlockTime | Stores the unlock time of a transaction (only if it has a non-zero lock time)
| Table | Key | Value | Description |

| `BlockHeaderBlobs` | BlockHeight | `StorableVec<u8>` | Maps a block's height to a serialized byte form of its header

<!-- TODO(Boog900): We could split this table again into `RingCT (non-miner) Outputs` and `RingCT (miner) Outputs` as for miner outputs we can store the amount instead of commitment saving 24 bytes per miner output. -->
