+## TRON使用Google protobuf协议，协议内容涉及到账户，区块，传输多个层面。
+
++	账户有基本账户、资产发布账户和合约账户三种类型。一个账户包含：账户名称，账户类型，地址，余额，投票，其他资产6种属性。
++	更进一步的，基本账户可以申请成为验证节点，验证节点具有额外的属性，投票统计数目，公钥，URL，以及历史表现等参数。
+
+   3种`Account`类型：`Normal`，`AssetIssue`，`Contract`。
+
+    enum AccountType {
  
+      Normal = 0;

+# Protobuf protocol
+
+## The protocol of TRON is defined by Google Protobuf and contains a range of layers, from account, block to transfer.
+
++ There are 3 types of account—basic account, asset release account and contract account, and attributes included in each account are name, types, address, balance and related asset.
++ A basic account is able to apply to be a validation node, which has serval parameters, including extra attributes, public key, URL, voting statistics, history performance, etc.
+
+     There are three different `Account types`: `Normal`, `AssetIssue`, `Contract`.
+
+      enum AccountType {
  
+         Normal = 0;
  
+         AssetIssue = 1;
  
+         Contract = 2;
+       
}

+     `account_name`: the name for this account – e.g. “_BillsAccount_”.  
+     `type`: what type of this account is – e.g. _0_ stands for type `Normal`.  
+     `balance`: balance of this account – e.g. _4213312_.  
+     `votes`: received votes on this account – e.g. _{(“0x1b7w…9xj3”,323), (“0x8djq…j12m”,88),…,(“0x82nd…mx6i”,10001)}_.  
+     `asset`: other assets expect TRX in this account – e.g. _{<“WishToken”,66666>,<”Dogie”,233>}_.
