BU-TOKEN(BU币)是BUMO主网的Token，BUMO是下一代商用级基础公共区块链，旨在建立价值流通的泛在信任网络，致力于打造广泛数字信任、价值自由流通、大众共享应用的分布式商业生态。
BU-TOKEN (BUKEN) is Token of the BUMO main network and BUMO is the next generation of basic public blocks at the commercial level, aimed at creating a general network of trust in the flow of values and working to create a wide range of digital trust, free circulation of values and distributed commercial ecology for applications shared by the general public.
打造新一代价值流通的泛在信任网络(Ubiquitous Trust Network)，使得“价值”有如“信息”一样地自甶流动。
Create a new generation of trust networks (Ubiquitous Trust Network) that allow & & & & rdquao; & & & ldquao; information & & rdquao; and self-mobilization.
BUMO的意义
The meaning of BUMO.
旨在建立广泛数字信任、资产自由流通、大众共有应用的区块链网络生态。着眼未来的价值流通网络，提供 开放、高效、扩展性强的底层技术支撑，契合金融、物联网、社交等各行业的资产数字化及价值流通需求；结合物联网技术，通过万物互联建立更广泛的“机器”信任，打造价值流通的坚实信任基础；将数字资产、智能设备、用户数据等有机地连接在一起，通过数字化交易及智能合约，让人们成为资产数字化及区块链新经济的真正受益者。
It is designed to create a broad network of digital trust, free circulation of assets, and community-based applications. It is based on a value-flowing network that provides open, efficient and well-extended bottom-of-the-board technology that matches the digitalization and value-flow needs of financial, physical, social and other industries; it combines material-networking technology to create a broader “ machine & & rdquo; trust to build a solid trust base for value flows; it is organically linking digital assets, smart equipment, user data, etc., to make people the real beneficiaries of the new economy of asset digitization and block chains through digital transactions and smart contracts.
BUMO的构建
BUMO 'S CONSTRUCTION
一是，无处不在的信任网络。区块链网络的信任基于无处不在的“机器”时，价值的流通才真正可信而高效。数字权力属于用户，让用户真正掌握自己的数字所有权，意味着所有用户共同参与到整个区块链网络的建设中来。通过全民参与、万物互联和民主共识，成为无处不在的信任网络。
One is the ubiquitous network of trust. Trust in the block chain network is based on the ubiquitous & ldquo; the machine & & rdquo; the flow of values is truly credible and efficient. Digital power belongs to the user, giving the user real ownership of his or her own digital ownership means that all users are involved in the construction of the entire block chain network. Through popular participation, connectivity and democratic consensus, it becomes an ubiquitous network of trust.
二是，可信的价值流通体系。“机器”与“机器”的连接，同时也是连接虚拟世界与现实世界之间的桥梁。当这样的一个泛在信任体系建立起来，网络的触角将无处不在，网络上的应用也将无处不在。价值将得以在这一泛在信任网络中自甶流动，形成可信的价值流通体系。
The second is a credible value flow system. & ldquo; machine & rdquo; connection with & & ldquo; machine & & rdquo; and a bridge between virtual and real worlds. When such a system of trust is built, the tentacles of the network will be everywhere, and the applications of the network will be everywhere. Values will be able to move from one network of trust to another, creating a credible system of value flows.

智能合约
Smart Contract
智能合约是区块链上一段可执行的图灵完备脚本，拥有自己的存储资源，通过交易触发合约后，合约引擎分配CPU和内存资源运行合约，从而完成业务逻辑。不同于传统的程序，智能合约需要满足两个特性，一是可停机，在有限时间范围内程序必须能够结束，这要求引擎能够采取方法度量合约可执行时间;二是确定性，同一输入必须产生对应的输出，这要求把所有不确定性因素排除掉。
A smart contract is an enforceable Turing script on the block chain, with its own storage resources. After a transaction triggers the contract, the contract engine allocates the CPU and the memory resource to run the contract, thus completing the business logic. Unlike traditional processes, the smart contract needs to meet two characteristics, one that can be shut down and the process must be able to end within a limited time frame, which requires that the engine be able to measure the time when the contract can be executed; and the other is certainty that the same input must produce the corresponding output, which requires all uncertainties to be removed.
BuContract(BUM〇 Contract)开发者可以自定义智能合约的读写操作供上层应用调用，底层账本会提供给智能合约访问链上数据的能力：全局状态、区块数据等，同时还能操作独有的数据存储区域以及发起合约交易与其他合约交互。
The BuContact Developer can customize the reading and writing operations of smart contracts for upper-level applications, and the bottom ledger will provide the ability of smart contracts to access data on the chain: global status, block data, etc., while also operating unique data storage areas and initiating contract transactions to interact with other contracts.
BuVM(BUM〇 Virtual Machine)是智能合约的执行环境，为应用层提供智能控制逻辑，与上层高级语言解析转换相结合，灵活支持虚拟机基础应用；通过定制化的API操作实现虚拟机的外置接口，可以灵活的与账本数据和外部数据进行交互。
BuVM (BUM0 Virtual Machine) is an implementation environment for smart contracts, providing intelligent control logic for the application layer, combined with advanced upper-level language deconstructs and flexible support for virtual machine base applications; the external interface of virtual machines through customized API operations allows for flexible interaction with book and external data.
BuContrac为了降低智能合约开发门槛，把区块链智能合约技术带给普通开发者，支持用JavaScript作为智能合约开发语言，这是全球最流行的开发语言之一；基于开源的Google Chrome V8引擎，实现了BuVM虚拟机。
To lower the threshold for intelligent contract development, BuContrac brought block chain smart contract technology to ordinary developers and supported JavaScript as an intelligent contract development language, one of the most popular development languages in the world; the open-source Google Chrome V8 engine enabled the BuVM virtual machine.
从而，有如下优点：
As a result, there are the following advantages:
一是，用户学习成本低，JS是Web最流行的语言；
One is that user learning costs are low, and JS is the most popular language in Web;
二是，执行效率高，不同于传统的基于栈的解释器，V8已经不是实际意义上的解释器，它采用延时编译及JIT技术直接把脚本语言翻译成目标机器二进制，使得执行效率等近似于本地程序。
The second is that, unlike the traditional warehouse-based interpreter, V8 is no longer a meaningful interpreter, using time delay compilation and JIT technology to translate script language directly into the target machine binary system, making implementation efficiency approximation to local procedures.
同时，BuVM将借助于WebAssembly技术快速支持C/C++、Python等开发语言，最终覆盖绝大多数开发者，对于智能合约后续在智能终端设备应用将起到很强的促进作用。
At the same time, BuVM will quickly support development languages such as C/C++ and Python with WebAssembly technology, eventually covering the vast majority of developers, and will be a strong catalyst for the follow-up of smart contracts in the application of smart terminal equipment.
为了对接链外现实世界数据，BuContract将支持两种方式：
To match real world data outside the chain, BuContrade will support two approaches:
(1)建立一个真实数据合约，甶数据提供商产生并维护，并且为其数据交一定押金，如果发现作恶，由记账人和其他社区参与者投票对其进行扣除押金的处理。
(1) The establishment of a real data contract whereby the data provider generates and maintains and pays a deposit for its data, and if the offence is found, the bookkeeper and other community participants vote for the deduction of the deposit.
(2)借助预言机(BuOracle，BUM〇 Oracle)，合约通过事件触发的方式通知预言机需要获取的数据，预言机处理完成后再传回给虚拟机，合约需要充分信任预言机。
(2) With the help of BuOracle, BUM0, Oracle, the contract provides notice of the data required by the pronunciation machine by means of incident triggers, the pronunciation machine is processed and returned to the virtual machine, and the contract requires full trust in the pronunciation machine.
BuContract将根据不同行业分类，提供合约模板，例如数字资产的发行，开发者只需要简单修改其中的参数即可快速安全的实现合约功能。BuContract将提供合约在线编辑及调试工具，可以帮助开发者高效率编写调试合约。
BuContrade will provide contract templates, such as the release of digital assets, according to different industry classifications, and developers can quickly and safely achieve contract functionality by simply modifying the parameters. BuContrade will provide online editing and debugging tools for contracts, which can help developers prepare debugging contracts efficiently.
