NEO platform offers storage ability for smart contract developers. Player's information can be stored into blockchain. Below describe how a player information stored into block:
The structure of byte storage
Due to complication of World Cup game, we have to store a lot of data. Below information describe the serialization of byte array.
1 byte 4 bytes uint array 4 bytes uint array 4 bytes uint array bet record array The length of balance | The balance amount | Last apply chips timestamp | The amount of bet records | The bets record.......
A sample of bet record: 4 bytes 1 byte (Win:0x1,Lose:0x2,Draw:0x3) 1 byte 4 bytes 4 bytes Match ID | bet type | is Calculated | odds x 1000 | Win Amount
MatchResult array(6 bytes): 4 bytes 1 byte 1 byte Match ID | TeamA Score | TeamB Score
