2、通过教程购买ATOM

Cosmos是一个并行网络，各链由诸如Tendermint共识提供支持。在cosmos生态系统中各空间可以相互通信、交易、互操作。Cosmos的愿景是打破区块链之间的障碍，创建一个区块链互联网，成为各种实际使用场景的优先选择平台。

这一实现伴随着一系列系统工具的开发，包括Tendermint，Cosmos SDK、IBC，Hub和Zone之间的通信，通过IBC协议实现。以太坊所采用的Go-Ethereum是单片技术堆栈范畴，对其特性的一些升级、以及定制性的提升，是2014成立的Tendermint最早的切入点。Tendermint BFT是一种解决方案，它将区块链的网络层和共识层打包，开发人员只需专注于应用层而无需在意底层协议，这一对开发者友好的设计在公链泛滥的当今看起来并无新意，但如果考虑这一设想最早出现在2014年底，就能自然而然明白cosmos的前瞻性了。

此外，Tendermint 共识算法的主要好处就是它具有安全简易的轻客戸端，这一点使其成为手机和物联网用例的理想工具。Tendermint 轻客戸端只需和验证组的变化保持一致，然后验证最新区块中预先提交的+⅔，来确定最新情况。总而言之，跨链不是comos的全部，Tendermint技术在开发时间的节省上也下了很大的功夫，Tendermint BFT的属性适用公链、私链，Tendermint BFT仅处理区块链的网络和共识，节点传播事务和验证器就一组事务达成一致，以附加到区块链，每秒可处理数千事务。

COSMOS建立在Tendermint的BPOS+PBFT的共识机制上。该机制涉及验证人与提议人。PBFT则用来确认区块的有效性，抵押代币的数量决定验证人投票的权重过程中的权力，BPOS用来分配验证人的权力。每轮的提议人会从验证人顺序列表中按照其选票比例来选择确定。Tendermint采用由绝对多数的选票三分之二选定的最优拜占庭容错算法。

一、Cosmos SDK

图1 Cosmos SDK功能

SDK在Tendermint BFT的基础上，进一步缩短第三方开发者的研发周期，首先，它允许开发人员在Golang上移植任何现有的区块链代码库，Ethermint面向以太坊网络。所有现有的工具（Truffle，Metamask等）都与Ethermint兼容，无需额外工作即可移植智能合约。cosmos SDK基于两个主要原则，在此基础上进一步规范了框架：

模块化： Tendermint团队构建了Cosmos Hub所需的基础模块。任何开发人员在构建自己的应用程序时都可以使用这些模块。并可以为Cosmos SDK创建一个模块。
安全边界：限制模块之间的安全边界，使开发人员能够更好地处理模块的可组合性，同时，限制恶意或意外交互的范围。

Cosmos SDK的详情可以在官网进行查阅，提供了用于构建命令行界面（CLI），REST服务器和各种其他常用的实用程序库。

二、IBC

在cosmos网络中，区块链之间的连接通过区块间通信协议（IBC）协议实现。IBC利用Tendermint共识，允许异构链将值（即token）或数据相互转移。异构链的特点是具有不同的层，各区块链由一组验证器维护，这些验证器称为矿工。在各自的网络中，共识、应用层皆有不同，为了与IBC兼容，需要遵循一些共识层的要求。IBC允许异构区块链相互传递令牌和数据，这意味着具有不同应用程序和验证器集的区块链是可互操作的。

链A上的一个帐户想要发送10个令牌到链B时，系统将连续地进行跟踪，将允许每个链跟踪另一个链的验证器集。且每一条链都运行另一条链的轻客户端。启动IBC传输时，IBC协议中的两个关键信息分别是IBCBlockCommitTx和IBCPacketTx，前者记录发送方所在的最新区块信息；后者是跨链交易本身的信息，执行时通过提及跨链指令存入outgoing队列；从outgoing队列取出交易信息，提交到Hub，由Hub执行后续步骤，以实现跨链交易。在此过程中，ATOM被锁定（绑定）在链A上，然后将10个ATOM的证据从链A转发到链B，并在链B上针对链A的有效性进行验证，如果有效，则在链B上创建10个ATOM凭证。在链B上创建的ATOM不是真正的ATOM，类似的机制用于在ATOM返回其原始链时解锁ATOM。

在IBC的设计原理上，通过直接连接可以将网络中的每个区块链彼此串联起来。但这种情况需要面临二次增长的不可控性，为了解决这个问题，Cosmos提出了一种模块化架构，在网络中具有两类区块链：枢纽Hub和区域Zone。前者专门设计用于将区域连接在一起。当区域与枢纽建立IBC连接时，它可以自动访问（即发送和接收）与其连接的每个其他区域。因此，每个区域只需要与一组受限的枢纽建立有限数量的连接。还可以防止区域内的双重支出。空间内部所有代币的转移将通过Cosmos Hub，Hub将完成各空间代币持有总量的记录，以及各空间的隔离，并囊括用户数据报协议（UDP）、传输控制协议（TCP）。Hub与各空间的状态变化会保持信息通信的一致，通过发布梅克尔证明（Merkle-proof）来说明信息已经被传送或接收。

Cosmos将在发布时提供良好的垂直可扩展性，在完成IBC模块后，将实施水平可扩展性解决方案。在Cosmos Network中推出的第一个Hub是Cosmos Hub。其令牌称为ATOM。Cosmos 中的验证人类似于提供机器的矿工，非验证人将ATOM权益代币委托用于投票。以此实现一定的ATOM奖励分配，当验证人被攻击或作恶时，系统采用一定的机制进行惩罚和削弱。

三、Cosmos可解决的区块链问题

1、可扩展性
工作量证明协议缓慢，昂贵，不可扩展且对环境有害。
Tendermint BFT解决了这个问题。
Tendermint BFT是拜占庭式容错共识引擎，可为Cosmos权益证明提供支持。

2、易用性
区块链应用程序很复杂，开发人员很难理解。
Cosmos SDK修复了此问题。
Cosmos SDK是用于构建可互操作的，特定于应用程序的区块链的模块化框架。

3、互通性
区块链经济孤立无援，彼此之间无法转移资产。
IBC协议解决了这个问题。
区块链间通信（IBC）是一种类似于TCP / IP的区块链消息传递协议。

四、主要特点和里程碑

Tendermint Core: “Tendermint Core”是一款即用型区块链引擎，配备 Cosmos 实用拜占庭容错共识协议。内核可用于搭建公共或私有区块链。共识机制提供即时结算和安保；优先保障安全，其次才是网络活跃度。

Cosmos SDK: 作为便利工具包，Cosmos SDK 有助开发者搭建应用专属的区块链。

跨链通信: 为了向开发者提供更多搭建区块链的工具，Cosmos 项目的下一个目标是提高不同区块链之间的互操作能力，实现跨链和跨层交易。借助分区组合，用户得以在 IBC 兼容链组成的代币生态系统内自由交易。

Cosmos is a parallel network, and each chain is supported by consensus such as Tendermint. In the cosmos ecosystem, various spaces can communicate, trade, and interoperate with each other. The vision of Cosmos is to break down the barriers between blockchains, create a blockchain Internet, and become the preferred platform for various practical use scenarios.

This implementation is accompanied by the development of a series of system tools, including Tendermint, Cosmos SDK, IBC, and communication between Hub and Zone is implemented through the IBC protocol. Go-Ethereum used by Ethereum is a monolithic technology stack. Some upgrades to its features and improvements in customization were the earliest entry points for Tendermint, which was established in 2014. Tendermint BFT is a solution that packages the network layer and consensus layer of the blockchain. Developers only need to focus on the application layer without caring about the underlying protocol. This developer-friendly design is very popular nowadays when public chains are flooding. It sounds nothing new, but if you consider that this idea first appeared at the end of 2014, you can naturally understand the forward-looking nature of Cosmos.

In addition, the main benefit of the Tendermint consensus algorithm is that it has a secure and simple light client, which makes it an ideal tool for mobile and IoT use cases. The Tendermint light client only needs to keep up with the changes in the validation group, and then verify the pre-committed +⅔ in the latest block to determine the latest situation. All in all, cross-chain is not all of Comos. Tendermint technology has also made great efforts in saving development time. The properties of Tendermint BFT are suitable for public chains and private chains. Tendermint BFT only handles the network and consensus of the blockchain, and node propagation Transactions and validators agree on a set of transactions to be attached to the blockchain, which can process thousands of transactions per second.

COSMOS is built on Tendermint’s BPOS+PBFT consensus mechanism. This mechanism involves validators and proposers. PBFT is used to confirm the validity of the block. The number of mortgage tokens determines the power of the validator in the weighting process of voting. BPOS is used to allocate the power of the validator. The proposer of each round will be selected from the validator order list according to the proportion of their votes. Tendermint uses an optimal Byzantine fault-tolerant algorithm selected by a supermajority of two-thirds of the votes.

1. Cosmos SDK

On the basis of Golang, it further shortens the research and development cycle of third-party developers. First, it allows developers to Port any existing blockchain code base, Ethermint targets the Ethereum network. All existing tools (Truffle, Metamask, etc.) are compatible with Ethermint, allowing smart contracts to be ported without additional work. The Cosmos SDK is based on two main principles that further standardize the framework:

Modularity: The Tendermint team built the foundational modules required for Cosmos Hub. Any developer can use these modules when building their own applications. And can create a module for the Cosmos SDK.
Security Boundaries: Restricting the security boundaries between modules enables developers to better handle the composability of modules while limiting the scope of malicious or unexpected interactions.

Details of the Cosmos SDK can be found on the official website, which provides libraries for building command line interfaces (CLI), REST servers and various other commonly used utilities.

2. IBC

In the cosmos network, the connection between blockchains is realized through the Inter-Block Communication Protocol (IBC) protocol. IBC utilizes the Tendermint consensus to allow heterogeneous chains to transfer values (i.e. tokens) or data to each other. Heterogeneous chains are characterized by having different layers, with each blockchain maintained by a set of validators called miners. In their respective networks, the consensus and application layers are different. In order to be compatible with IBC, some consensus layer requirements need to be followed. IBC allows heterogeneous blockchains to pass tokens and data to each other, meaning blockchains with different applications and validator sets are interoperable.

When an account on chain A wants to send 10 tokens to chain B, the system will track it continuously, allowing each chain to track the validator set of the other chain. And each chain runs a light client of the other chain. When starting an IBC transfer, the two key pieces of information in the IBC protocol are IBCBlockCommitTx and IBCPacketTx. The former records the latest block information where the sender is located; the latter is the information of the cross-chain transaction itself, which is deposited by mentioning the cross-chain instructions during execution. outgoing queue; take out the transaction information from the outgoing queue and submit it to the Hub, and the Hub will perform subsequent steps to achieve cross-chain transactions. During this process, ATOM is locked (bound) on chain A, then forward the evidence of 10 ATOMs from chain A to chain B, and verify the validity of chain A on chain B. If valid, create 10 ATOM credentials on chain B. The ATOM created on chain B is not a real ATOM, a similar mechanism is used to unlock the ATOM when it returns to its original chain.

Based on the design principle of IBC, each blockchain in the network can be connected to each other through direct connections. However, this situation requires the uncontrollability of secondary growth. In order to solve this problem, Cosmos proposes a modular architecture with two types of blockchains in the network: Hub and Zone. The former is specifically designed to tie areas together. When a zone establishes an IBC connection with a hub, it can automatically access (i.e. send and receive) every other zone connected to it. Therefore, each region only needs a limited number of connections to a restricted set of hubs. Also prevents double spending within a zone. The transfer of all tokens within the space will go through the Cosmos Hub. The Hub will complete the record of the total amount of tokens held in each space, as well as the isolation of each space, and include User Datagram Protocol (UDP) and Transmission Control Protocol (TCP). The status changes between the Hub and each space will maintain the consistency of information communication, and the information has been transmitted or received by issuing Merkle-proof (Merkle-proof).

Cosmos will provide good vertical scalability at launch, and horizontal scalability solutions will be implemented after the IBC module is completed. The first Hub launched in Cosmos Network is Cosmos Hub. Its token is called ATOM. Validators in Cosmos are similar to miners who provide machines, and non-validators delegate ATOM stake tokens for voting. In this way, a certain ATOM reward distribution is achieved. When the validator is attacked or does evil, the system uses a certain mechanism to punish and weaken it.

3. Blockchain problems that Cosmos can solve

1. Scalability
Proof-of-work protocols are slow, expensive, unscalable and Harmful to the environment.
Tendermint BFT solves this problem.
Tendermint BFT is a Byzantine Fault Tolerant consensus engine that powers Cosmos Proof of Stake.

2. Ease of use
Blockchain applications are complex and difficult for developers to understand.
The Cosmos SDK fixes this issue.
The Cosmos SDK is a modular framework for building interoperable, application-specific blockchains.

3. Interoperability
The blockchain economy is isolated and cannot transfer assets between each other.
The IBC protocol solves this problem.
Inter-Blockchain Communication (IBC) is a blockchain messaging protocol similar to TCP/IP.

4. Main features and milestones

Tendermint Core: “Tendermint Core” is a ready-to-use blockchain engine equipped with Cosmos Practical Byzantine Fault Tolerance consensus protocol. The core can be used to build public or private blockchains. The consensus mechanism provides instant settlement and security; security is prioritized, followed by network activity.

Cosmos SDK: As a convenient toolkit, Cosmos SDK helps developers build application-specific blockchains.

Cross-chain communication: In order to provide developers with more tools to build blockchains, the next goal of the Cosmos project is to improve the interoperability between different blockchains and achieve cross-chain and cross-layer trade. With the help of zone combinations, users can trade freely within the token ecosystem composed of IBC compatible chains.
