在PlatON新贝莱世界测试网0.13.0版本即将上线之际，为更好地适配主网上线工作并为用户提供更直观的产品体验，PlatON将正式启用全新账户地址格式！由hex+EIP55规范转为带固定前缀的bech32地址编码规范。
为什么采用bech32地址编码？
PlatON底层使用byte的形式存储地址，当地址需要显示给用户时，当前的规则是将地址转成16进制字符串，然后采用EIP55的标准对所得字符串中的部分字母转大写，得到最终地址字符串，例如:
0x7cB0f5D66D07472A835C97e288931BE2518f7b21
这种字符串虽然可以通过计算机校验（是否符合EIP55规范），但对用户来说辨识度不高。
在对各主流公链的地址生成进行充分调研后，我们决定采用bech32的方式对内部地址编解码成字符串来对外显示，长度与原编码方式长度保持一致，均为42，hrp（human readable part)为lat（主网）和lax（其他网络）。
例如：lax10jc0t4ndqarj4q6ujl3g3ycmufgc77epxg02lt
注：
· 主网前缀为lat，其他网络前缀为lax
· bech32是基于base32的一种编码方式，可以快速交易生成的地址并且生成的地址具有辨识度。

全新账户地址 “超级符号”诞生
此次更新账户地址格式，除了由hex+EIP55规范转为带固定前缀的bech32地址编码规范之外，最大、最直观的变化莫过于加入了前缀“lat”（测试网为“lax”）。PlatON作为隐私计算网络与金融基础设施，LAT是底层金融基础设施重要的流通凭证，也是PlatON经济机制模型中的核心支撑。此次“lat”前缀的加入，增加了PlatON品牌的辨识度，全面提升了用户认知，并将“lat”升级为超级符号，覆盖全球用户。
升级后的全新账户地址格式如下：
