2、通过教程购买ECOC

ECOChain是一个真正快速且经济友好的分散式公共链,使用在虚拟机 (VM) 中执行的以太坊智能合约。由一家著名的国际区块链团队发起,它利用区块链技术作为基础,探索全球经济市场和区块链世界,构建全球分散分布式生态系统。

ECOChain的使命在未来经济市场体系的开发中,经济合作组织肩负着充分挖掘区块链优势的使命,运用传统的经济市场体系,重塑新的经济生态系统,实现良好、可信、快速、财务友好、经济友好的分散生态系统。同时,它使更多的人拥有一个安全和高质量的分布式安全网络,使市场的健康和值得信赖的发展和激励通过经济合作链来实现。这也是经合组织链小组的使命。

 

 

ECOChain的独特特点

 

在技术层面,ECOChain使用区块链技术(通信协议、加密等)构建,以确保用户之间的连接没有障碍。它具有以下独特优势:

1. 高性能
(1) 用户可以体验到高交易速度经济链利用长期以来已知的通信协议,以最大限度地发挥其效益。各种模型分析和压力测试鞋,它可以支持高达 560 交易每秒。
(2) 有效的自适应共识算法是由经社理事会提供的区块链协议。该自适应算法保证了公有链的高效并发处理,并准确解决了节点错误和网络连接问题。
(3)快速交易确认。ECOC使用高效且自适应的协商一致算法来确保完成事务,即事务确认,并优化事务确认过程中的其他属性,如加密安全签名算法和分类帐存储方法。
 (4) 对于存储,ECOC支持本地数据库存储、文件系统存储和云存储。本地存储实现冷热分离,数据库存储使用数据库和表模型,云存储支持根据云群集规则进行扩展。

2. 高速访问ECOC基于最小化业务应用程序开发圈、满足程序员现有的开发知识以及以高安全性促进其部署和维护的原则。因此,它在用户业务开发、部署和安全性方面实现了许多兼容性。该生态系统为用户和开发人员提供了许多客户端(不同钱包类型)和工具 (SDK),他们可以选择如何连接到具有良好UI体验、高安全性、更低的成本和快速速度的区块链。SPV(简单的验证付款)客户端也可以使用,使得许多操作成为可能,而无需运行完整节点,但也不使用第三方服务(信任较少操作)。

3. 高安全性
(1) 可靠且一致的存储ECOC保证在传输过程中不会通过非对称加密和数字签名(公共加密)篡改服务请求,并通过协商一致机制存储每个节点的数据。对于存储的数据记录,节点内的自检和准实时多节点数据验证用于确保无法修改存储的数据记录。
(2) 用户隐私和交易保密性ECOC中的用户真实身份和区块链公共地址是孤立的。公共地址是假名。无法从每个节点的记录存储获取关联的用户信息。用户信息存储具有多层保护,如权限控制、访问身份验证和加密存储。事务保密性较高的用户也可以选择独立于事务的机制。同一用户的每个事务都映射到区块链上的不同地址,从而确保无法在分类账上获取用户的多个记录(不可追踪)。
(3) 安全密钥管理系统在ECOC密钥管理解决方案中,提供了密钥安全和用户帐户委派功能,以确保密钥的安全性。密钥安全使用用户信息加密私钥。在正常业务流程下无法访问密钥安全。存在CLI和GUI工具以脱机保存密钥(冷存储)。此外,内部共识算法,投注者可以在形成块(Coinbase交易)时使用同一钱包的不同账户进行共同签名。这增强了赌注者的安全性。
(4) 操作效率ECOChain为数据指标(分析)构建 GUI和CLI工具。根据应用程序和业务 Dapp 的需求,智能合约的存储和区块链数据可以进行测试、检查、筛选或自定义,以生成任何类型的报告。此外,还存在用于代码编译的增强编译器。存在用于安全分析、智能合约的成本和性能的其他工具。所有这些都属于经济合作组织(ECOC)的生态系统。ECOChain提供通用和高效的信息收集组件,这些组件部署在业务层、共识节点层和分类帐存储层。信息收集组件将机器的系统信息(如CPU、内存、硬盘和网络状态)和节点使用状态(如节点访问、花费的时间、节点运行状况等)和业务使用情况(业务访问、成功率、耗时分发等)实时显示在监控界面上,以方便整个系统的管理。

 

 

ECOChain的生态系统扩展

 

随着经济合作链生态系统的不断完善、扩展和发展,越来越多的使用案例能够得到解决,而经济合作组织链的可用性将增强,从而带来更高的流通量和不可避免的更高价值。

用例1:交易市场商城经济
交易市场商城不仅给人们带来了便利,而且带来了巨大的交通流量。ECOC链将建立一个分散的在线经济市场交易平台,在这些平台上显示各种项目。买方和卖方就ECOChain平台上的智能合同达成一致。买方在区块链上放置一定数量的代币。卖方确认项目收到正确后,区块链上的令牌将自动发送到卖方的帐户。否则,如果买方尚未收到该项目或尚未确认,根据智能合约的协议,区块链上的令牌将返回到买方的帐户。对于某些大额交易,需要多种保护措施。人工智能技术可用于保护链条上记录的物品的产权,以避免双方违反合同。需要一定数额的存款(担保)。这种类型的买卖过程不仅安全,而且保护买卖双方的权利。

用例2:跨链事务和互操作性
如今,区块链具有许多不同的架构、属性和目标。有些人会活下来,另一些人不会。但是,是否可以以分散的方式将它们连接起来呢?分散的链(跨链)连接为连接的链和区块链行业增加了价值。应用程序可以普遍使用;网络效应提高了其可用性,并保留了权力下放(信任少财产)。经合组织已经在为此而努力。原子交换代码正在作为开源实现,存储库发布在 GitHub(GitHub源代码) 上。第一个目标就是以太坊,因为它是一个有着丰富生态系统的大平台。其他平台将跟随。原子交换是以完全分散的方式交换资产,这意味着在不同的链之间进行硬币或代币交换,而无需第三方或保管人。今后,将实现经合组织链与运行虚拟机的其他链之间的互操作性。一张关于跨链的黄色纸张也在进行中。

用例3:Oracle 的单独协议(共识)
虚拟机是确定性状态机。它与外部世界隔绝。这意味着它无法从外部访问任何数据。获取数据的唯一方法是从有权访问智能合约(通过合同函数)的人输入数据。有权访问这些函数的实体可以使VM代码有用。通常的例子是汇率数据。这就是术语"oracle"的诞生方式。对智能合约具有特殊访问权限并定期使用真实数据馈送它的实体是oracle。术语可能源于一个事实,即此实体(通常是服务器)受到应用程序用户的高度信任。这样,分散式应用程序就可以为实际用例运行。

用例4:位置证明的应用(PoL)
位置证明是实体必须向其他人证明其真实(物理)位置的问题。GPS系统向某人提供信息,以自动计算其位置,并出现小错误。问题是,这个GPS信息不能被用来说服别人。因此,整个问题是,如何有人可以证明,在给定的时间,他不伪造它的位置。PoL最常见的案例是应用于物流链。关于关键产品,如食品和药品,问题更加紧迫。还有其他用例。PoL没有常规解决方案。幸运的是,用例是特定的和位置绑定的。在这些地方,可以从不同的实体使用特殊硬件。我们称为用例3的oracle系统可在此处以完全信任的方式提供PoL。硬件、Oracle 共识和利益点的网状网络可以提供可行的解决方案。

2. Purchase ECOC through tutorials< /p>

ECOChain is a truly fast and economically friendly decentralized public chain using Ethereum smart contracts executed in a virtual machine (VM). Initiated by a well-known international blockchain team, it uses blockchain technology as a basis to explore the global economic market and blockchain world and build a global decentralized distributed ecosystem.

ECOChain’s mission In the development of the future economic market system, the Economic Cooperation Organization shoulders the mission of fully exploring the advantages of blockchain, using the traditional economic market system to reshape the new economic ecosystem and achieve good , trusted, fast, financially friendly, and economically friendly decentralized ecosystem. At the same time, it enables more people to have a safe and high-quality distributed security network, enabling the healthy and trustworthy development and incentives of the market to be realized through the economic cooperation chain. This is also the mission of the OECD Chain Group.

The unique characteristics of ECOChain

At the technical level, ECOChain is built using blockchain technology (communication protocol, encryption, etc.) , to ensure there are no obstacles to the connection between users. It has the following unique advantages:

1. High performance
(1) Users can experience high transaction speeds. The economic chain utilizes long-known communication protocols to maximize its benefits. Various model analysis and stress testing shoes, it can support up to 560 transactions per second.
(2) The effective adaptive consensus algorithm is the blockchain protocol provided by the Economic and Social Council. This adaptive algorithm ensures efficient concurrent processing of public chains and accurately resolves node errors and network connection issues.
(3) Fast transaction confirmation. ECOC uses an efficient and adaptive consensus algorithm to ensure completion of transactions, known as transaction confirmation, and optimizes other properties in the transaction confirmation process, such as cryptographically secure signature algorithms and ledger storage methods.
(4) For storage, ECOC supports local database storage, file system storage and cloud storage. Local storage implements hot and cold separation, database storage uses database and table models, and cloud storage supports expansion according to cloud cluster rules.

2. High-speed access ECOC is based on the principles of minimizing the business application development circle, satisfying programmers' existing development knowledge, and promoting its deployment and maintenance with high security. Therefore, it achieves many compatibility in terms of user business development, deployment and security. The ecosystem provides users and developers with many clients (different wallet types) and tools (SDKs), and they can choose how to connect to the wallet with a good UIBlockchain with proven, high security, lower cost and fast speed. SPV (Simple Verify Payment) clients are also available, making many operations possible without running a full node, but also without using third-party services (trust less operations).

3. High security
(1) Reliable and consistent storage ECOC guarantees that service requests will not be tampered with during the transmission process through asymmetric encryption and digital signatures (public encryption), and through consensus The mechanism stores data for each node. For stored data records, in-node self-tests and near-real-time multi-node data validation are used to ensure that stored data records cannot be modified.
(2) User Privacy and Transaction Confidentiality The user’s real identity and blockchain public address in ECOC are isolated. Public addresses are pseudonyms. Unable to obtain associated user information from each node's record store. User information storage has multiple layers of protection, such as permission control, access authentication, and encrypted storage. Users with higher transaction confidentiality can also choose a transaction-independent mechanism. Each transaction for the same user is mapped to a different address on the blockchain, ensuring that multiple records of a user cannot be obtained on the ledger (untraceable).
(3) Security Key Management System In the ECOC key management solution, key security and user account delegation functions are provided to ensure the security of keys. Key Security uses user information to encrypt private keys. Key security cannot be accessed under normal business processes. CLI and GUI tools exist to save keys offline (cold storage). Additionally, with the internal consensus algorithm, bettors can co-sign using different accounts from the same wallet when forming blocks (Coinbase transactions). This enhances the security of bettors.
(4) Operational efficiency ECOChain builds GUI and CLI tools for data indicators (analysis). Depending on the needs of the application and business Dapp, smart contract storage and blockchain data can be tested, inspected, filtered, or customized to generate any type of report. Additionally, enhanced compilers exist for code compilation. Other tools exist for security analysis, cost and performance of smart contracts. All of these belong to the Ecosystem of the Economic Cooperation Organization (ECOC). ECOChain provides general and efficient information collection components, which are deployed at the business layer, consensus node layer and ledger storage layer. The information collection component collects the machine's system information (such as CPU, memory, hard disk and network status) and node usage status (such as node access, time spent, node operating status, etc.) and business usage (business access, success rate, time-consuming Distribution, etc.) are displayed on the monitoring interface in real time to facilitate the management of the entire system.

ECOChain’s ecosystem expansion

With the continuous improvement, expansion and development of the economic cooperation chain ecosystem, more and more The more use cases can be addressed and the availability of the ECO chain will be enhanced, leading to higher circulationquantity and inevitably higher value.

Use Case 1: Trading Market Mall Economy
The Trading Market Mall not only brings convenience to people, but also brings huge traffic flow. ECOC Chain will establish a decentralized online economic market trading platform where various projects will be displayed on these platforms. The buyer and seller agree on a smart contract on the ECOChain platform. The buyer places a certain amount of tokens on the blockchain. Once the seller confirms that the item was received correctly, the token on the blockchain will be automatically sent to the seller's account. Otherwise, if the buyer has not received the item or has not confirmed it, the tokens on the blockchain will be returned to the buyer's account according to the smart contract's agreement. For some large transactions, multiple protection measures are required. Artificial intelligence technology can be used to protect the property rights of items recorded on the chain to avoid breach of contract by both parties. A certain amount of deposit (guarantee) is required. This type of buying and selling process is not only safe but also protects the rights of both the buyer and seller.

Use Case 2: Cross-Chain Transactions and Interoperability
Today, blockchains have many different architectures, properties, and goals. Some people will survive, others won't. But is it possible to connect them in a decentralized way? Decentralized chain (cross-chain) connections add value to the connected chain and blockchain industry. Applications can be universally used; network effects increase their usability and preserve decentralization (trust less property). The OECD is already working on this. The atomic swap code is being implemented as open source and the repository is published on GitHub (GitHub Source Code). The first target is Ethereum because it is a large platform with a rich ecosystem. Other platforms will follow. Atomic swaps are the exchange of assets in a fully decentralized manner, meaning the exchange of coins or tokens between different chains without the need for a third party or custodian. In the future, interoperability will be achieved between the OECD chain and other chains running virtual machines. A yellow paper on cross-chaining is also in progress.

Use Case 3: Oracle’s Separate Protocol (Consensus)
The virtual machine is a deterministic state machine. It is isolated from the outside world. This means it cannot access any data from the outside. The only way to get data is to enter it from someone who has access to the smart contract (via the contract function). Entities with access to these functions can make VM code useful. A common example is exchange rate data. This is how the term "oracle" was born. The entity that has special access to the smart contract and regularly feeds it with real data is the oracle. The terminology probably stems from the fact that this entity (usually a server) is highly trusted by the application's users. This way, decentralized applications can run for real-world use cases.

Use Case 4: Application of Proof of Location (PoL)
Proof of Location is a problem where an entity must prove its true (physical) location to others. GPS systems provide information to someone to automatically calculate their location, subject to minor errors. The problem is, this GPS information cannot be usedConvince others. So the whole question is, how can someone prove that at a given time he is not faking its location. The most common case of PoL is applied to the logistics chain. Regarding key products, such as food and pharmaceuticals, the questions are even more pressing. There are other use cases. There are no conventional solutions for PoL. Fortunately, use cases are specific and location-bound. In these places, special hardware is available from different entities. Our oracle system, which we call use case 3, provides PoL here with full trust. A mesh network of hardware, Oracle consensus, and points of interest can provide a viable solution.
