Store:

主要存储以下数据：

• 链数据（高度、拓扑高度，区块全排序，末端区块）
• 区块数据（区块）
• 交易数据（交易、交易所在区块高度，密钥镜像）

Store_Block_Topological_order

// stores a blocks topological order

Store_TX

// store a tx
// this only occurs when a tx has been mined or a a reorganisation is in progress
// stores a height to show at what height it has been mined

Store_TX_Height

// load height at which a specific tx was mined

Store_BL

// TODO the miner tx should be extracted ands stored from somewhere else
// NOTE: before storing a block, its transactions must be stored

Store_TOPO_HEIGHT

Store_TOP_HEIGHT

Store_KeyImage

store_TX_in_Block

store_TIPS

// store settle status within the block
// a blockid with stored with value 1  == it has been settled
// a blockid stored with value 0  == it has not been settled
// a blockid not found in store == it has NOT been settled

你让它存什么，它就存什么，不做任何与业务相关的判断。

Load_TOPO_HEIGHT

// faster bootstrap

Get:

Get_Block_Past

// all the immediate past of a block

Get_Block_Future

// a block withput a future is called tip

Get_Block_Output_Index

// get the position from where indexing must start for this block
// indexing mean vout based index
// cryptonote works by giving each vout a unique index number

Get_Blocks_At_Height

其它:

Is_Block_Topological_order

// since topological order might mutate, instead of doing cleanup, we double check the pointers

IS_TX_Valid

mark_TX

// this will mark a block, tx combination as valid/invalid
