宇宙 -> 星系 -> 行星

数据包括：

• 历史数据（原生数据）
• 状态数据（衍生数据）

UNIVERSE

var BLOCKCHAIN_UNIVERSE = []byte("U") //[]byte("BLOCKCHAIN_UNIVERSE") // all block chain data is store in this BLOCKCHAIN_UNIVERSE
var SMARTCONTRACT_UNIVERSE = []byte("SC")

区块链

智能合约

GALAXY

var GALAXY_BLOCK = []byte("GB")
var GALAXY_TRANSACTION = []byte("GTX")           // []byte("TRANSACTION")
var GALAXY_TRANSACTION_VALIDITY = []byte("GTXV") //[]byte("TRANSACTIONVALIDITY")
var GALAXY_KEYIMAGE = []byte("GKI")              //[]byte("KEYIMAGE")

var GALAXY_TOPOLOGICAL_ORDER = []byte("GT")  // []byte("TOPOLOGICAL")       // stores  block to topo index mapping
var GALAXY_TOPOLOGICAL_INDEX = []byte("GTI") //[]byte("TOPOLOGICAL_INDEX") // stores topological index  to block mapping

//2 galaxies store inverse mapping
var GALAXY_HEIGHT = []byte("GH")        //[]byte("HEIGHT")             // height to block id mapping
var GALAXY_OUTPUT_INDEX = []byte("GOI") //[]byte("OUTPUT_INDEX") // output index to wallet data for blockchain verification and wallets

// these store unstructured data
var GALAXY_KEYVALUE = []byte("GKV") //[]byte("KEYVALUE") // used to store simple data

区块、交易、密钥镜像

全排序、映射关系

高度、输出索引

// the various attributes stored in keyvalue
var TOP_HEIGHT = []byte("TOP_HEIGHT")   // stores current TOP HEIGHT, only stores single value
var TOPO_HEIGHT = []byte("TOPO_HEIGHT") // stores current TOPO HEIGHT, only stores single value
var TIPS = []byte("TIPS")               // this stores tips

高度、拓扑高度、末端区块

var PLANET_MINERTX_REWARD = []byte("REWARD")          //reward for minertx is stored here ( base reward + collected fees after client protocol run)

var PLANET_TIMESTAMP = []byte("TS") // []byte("TIMESTAMP")

// the TX has the following attributes
var PLANET_TX_BLOB = []byte("BLOB")          // contains serialised  TX , this attribute is also found in BLOCK where
var PLANET_TX_MINED_IN_BLOCK = []byte("MBL") //[]byte("MINERBLOCK") // which blocks mined this tx, stores topo height of mined block

复杂的数据结构有 Block、Tips、Transaction，其它 uint64、Timestamp、bytes，其它 TX_Output_Data（在钱包同步时，提供数据）。
