EOSDevHelper is a cross-platform EOS PC wallet tool,which is developed by OracleChain.io.

EOSDevHelper是一個跨平臺PC端EOS錢包工具，由OracleChain團隊研發。

注意：此工具用於輔助智慧合約開發，並不是真正的錢包，錢包功能僅用於開發測試，請不要將EOS主網私鑰匯入此工具中，安全性不能保證。

ATTENTION: This Tool is used for developing EOS smart contract, it is NOT a real EOS wallet. The wallet in this tool is testnet only, please do NOT import your EOS private keys.

Overview/簡介

  The EOSDevHelper program is a light weighted wallet build on EOSIO ecology. It provides private basic key store with encryptions, signature, validation functions, and etc. Developers can use this tool connect the EOSIO testnet, and test the wallet/account/contracts interface in a more convenient way.

  EOSDevHelper是一個建立在EOSIO生態上的錢包工具。它提供了基礎的錢包功能，包含了私鑰加密管理、簽名校驗模組。開發者可以使用EOS開發助手連線EOSIO網路，更便捷地對錢包、賬號、合約介面等進行開發和測試。

ENVIRONMENT/開發和使用環境

Compile from source code/如何從原始碼編譯：

 MACOS、WINDOWS、UBUNTU

 1. install QT >= 5.8

 2. download our git repository.

git clone --recurse-submodules https://github.com/OracleChain/EOSDevHelper.git

 3. open Qt Creator and choose “Open Project”, select the “src/EOSDevHelper.pro” and open

 4. select Build from QT menu and Run it.

For ubuntu, if build with errors like connot find -lGL, this means the openGL development library is missing.
Just using this command to install:
sudo apt-get install build-essential libgl1-mesa-dev

DOWNLOAD & TRY/下載試用

For Ubuntu: Tested on Ubuntu 16.04 x64, you should chmod +x start.sh, then use ./start.sh .

DEPENDENCYS/依賴庫:

 1.our ECDSA is based on micro-ecc

  橢圓曲線演算法實現來自micro-ecc

  https://github.com/kmackay/micro-ecc

 2.We build a Publicly Verifiable Secret Sharing on secp256k1 which is published by Schoenmakers on crypto99 conference.

  我們在橢圓曲線secp256k1上實現了Schoenmakers在crypto99上提出的Publicly Verifiable Secret Sharing

About OracleChain/有關歐鏈

As the world’s first application built on an EOS ecosphere, OracleChain needs to meet the demands of the Oracle (oracle machine) ecosystem by efficiently linking blockchain technology services with various real-life scenarios, thereby delving into this immense tens of billions of dollars valuation market.

OracleChain（歐鏈）作為全球第一個直面區塊鏈生態Oracle（預言機）需求的基礎應用，將區塊鏈技術服務和現實生活中的多種需求場景直接高效對接，深耕這個百億美金估值的巨大市場。

As a decentralized Oracle technology platform based on the EOS platform, the autonomous Proof-of-Reputation & Deposit mechanism is adopted and used as a fundamental service for other blockchain applications.In addition to Oracle services that provide real-world data to the blockchain, Oracle services that provide cross-chain data are also offered. Given that OracleChain can accomplish the functions of several prediction market applications, such as Augur and Gnosis, OracleChain can also support smart contract businesses that require high-frequency access to outside data in certain scenarios, such as Robo-Advisor.

OracleChain是一個多區塊鏈的去中心化Oracle技術平臺，採用自主的PoRD機制，將現實世界資料引入區塊鏈，並將此作為基礎設施為其他區塊鏈應用提供服務。
OracleChain將在區塊鏈內提供現實世界資料的Oracle服務，同時還可以提供跨鏈資料的Oracle服務。基於OracleChain除了能實現Augur、Gnosis等預測市場（Prediction Market）應用的功能之外，還能支撐對鏈外資料有更高頻率訪問需求的智慧合約業務，比如智慧投顧等場景。

OracleChain will nurture and serve those blockchain applications that change the real world. Our mission is to “Link Data, Link World,” with the aim of becoming the infrastructure linking the real world with the blockchain world.

OracleChain將改變當前區塊鏈應用的開發模式，建立全新的生態圈，服務於真正能改變現實世界的區塊鏈應用。

By achieving intra-chain and extra-chain data connectivity, we aspire to create a service provisioning platform that can most efficiently gain access to extra-chain data in the future blockchain world.

OracleChain的使命是“讓世界與區塊鏈互聯”，立志成為連結現實世界與區塊鏈世界的基礎設施，通過把外部資料引入區塊鏈來實現鏈內鏈外的資料互通，OracleChian將是未來區塊鏈世界中最高效的獲取鏈外資料的服務提供平臺。
