技术进展
UChain区块链项目团队Testnet测试网络封闭式研发进入第二周，目前整个加密模块的研发基本完成，Testnet作为UChain公链研发的第一个里程碑，目前开发进程非常顺利，欢迎持续关注。
Technical Progress Report
UChain Testnet has finished the second week of R&D. So far, the research on the cryptographic module is almost finished, and Testnet has undergone a smooth development process as the first milestone of UChain’s public blockchain R&D. Your continuous attention is welcomed and appreciated.
1.SHA256摘要算法实现
进度100%
SHA256算法原理上周做了介绍，本周该算法模型的基础代码已全部完成，接下来我们会做一些针对该算法的单元测试。
1. Achievement of SHA256 digest algorithm
Progress 100%
The principle of the SHA256 algorithm was introduced last week and the basic code of this algorithm model has been finished this week. Next, we will carry out some unit tests regarding this algorithm.
2.Base58Check编码方式的实现
进度100%
Base58Check编码工作全部完成，即将进入单元测试。
2. Achievement of Base58Check coding method
Progress 100%
Base58Check coding has been finished and will proceed onto the stage of unit testing.
3.ECC算法
进度100%
椭圆曲线加密算法，一种非对称加密算法，该算法原理在UChain白皮书有详细阐述。其优势是密钥更小，160位的椭圆密钥与1024位的RSA密钥安全性相同，对带宽要求更低且节省存储空间。
3. ECC Algorithm
Progress 100%
Elliptic Curve Cryptography (ECC) algorithm is an unsymmetrical encrypted algorithm and its principle is described in detail in the UChain white paper. With the advantage of a smaller encryption key, 160-digit elliptic encryption key boasts the same safety as 1024-digit RSA secret key, thus requiring less bandwidth, and saving storage space.
4.RIPEMD160函数
进度100%
以MD4为基础设计的加密哈希函数，同时也存在着128、256、320位元的算法，称为RIPEMD-128,RIPEMD-256和RIPEMD-320。
4. RIPEMD160 Function
Progress 100%
Cryptographic hash function based on MD4, with other algorithms including 128, 256 and 320 bits also exist, called RIPEMD-128, RIPEMD-256 and RIPEMD-320.
5.AES加密算法
进度100%
AES算法的模块在分组密码领域常有使用，涉及4种操作：字节替代（SubBytes）、行移位（ShiftRows）、列混淆（MixColumns）和轮密钥加（AddRoundKey），整个过程可逆，保证数据能被正确还原。
5. AES Encrypted Algorithm
Progress 100%
The module of the AES algorithm is often used in block cipher and involves four kinds of operations, namely SubBytes, ShiftRows, MixColumns and AddRoundKey. The whole process is reversible to make sure data can be restored correctly.
6.MerkleTree
进度100%
MerkleTree是一种特殊的二叉树，叶子节点是原始数据，非叶子节点是下面所有叶子节点值通过特殊计算得到，任何叶子节点上的数据更改都会传递到根节点上。UChain区块交易数据存储就是采用MerkleTree数据结构。
UChain测试小组将对以上六个模块进行单元测试，测试结果将在下周公布。
6. MerkleTree
Progress 100%
MerkleTree is a special binary tree, the leaf nodes are original data and non-leaf nodes are obtained by special calculation of all leaf node values under. Any data change on leaf nodes will be transmitted to root nodes. Transaction data of UChain blockchain is stored by using MerkleTree data structure.
UChain team will carry out unit tests to the above six modules and release the test results next week.

UChain简介
UChain是专为全球共享经济而设计的公共基础设施区块链网络。与其他共享经济企业一起，建立一个分散的全球共享经济生态系统，每个用户都可以在没有中介的情况下自由交换价值和发布需要共享的内容。UChain通过区块链生成和共享交易活动数字账簿的数据结构，其核心设计思想是系统中的每个网络节点都参与全网公开账簿记账，经多次确认进入历史的区块链信息将永久记录，无法进行任何修改。这种分布式总账结构保证了所记录信息的不可篡改且可追溯，创造出一条“去中心化”的、牢不可破的网络“信任链”。
UChain profile
UChain is an infrastructure blockchain network specifically designed for the global sharing economy. Together with other sharing economy enterprises, it establishes a decentralized ecosystem for the global sharing economy where each user can, without intermediary, exchange values freely and issue content to be shared. UChain generates and shares data structure of a digital account book for transaction activities via blockchain. The core design concept is that each network node will be involved in open account bookkeeping through the whole network, and blockchain information that has become part of the history upon confirmation many times will be recorded permanently, with no revisions being allowed. Such a distributed ledger structure makes sure the information recorded is traceable and cannot be tampered with, thus creating a decentralized network chain trustworthy and impossible to break.
