解析：

structs 定义函数   没个数组行，代表一个函数，函数名 name 函数参数 fields

actions 定义输出接口（输出哪几个函数）
　　比如上例子的 confirm 函数， 函数参数从structs 里找
　　实际调用命令 cleos push action deposit.tx confirm '["p1","p2","p3","p4","p5"]' -p eosuserxxx
　　["p1","p2","p3","p4","p5"] 对应 fields： validator from to quantity txhash

tables 定义表 ， 表名 name, scope 从 get scope deposit.tx 找
　　如果 scope 不存在，返回空行
比如 ：
cleos get table deposit.tx xxxx transactions
cleos get table deposit.tx ......2cel2kc transactions

cleos get scope deposit.tx
查表数据
cleos get table deposit.tx USDT transactions
