前言

本文由ITAM在5月10日发表于ITAM的Medium官方主页。本篇文章介绍了ITAM有关底层公链自由选择的理念，大家都知道ITAM是部署在EOS链上的应用，其能够直接使用EOS链的诸多基础设施来帮助其实现发展目的，应该说ITAM的发展仰赖于EOS链强大的基础设施。但也应该看到，EOS链并非十全十美，其竞争链如ETH、波场、本体等也各有特色和优势，不同诉求的用户可能会更倾向于不同的公链选择。现在ITAM很可能会展示一项技术，让所有用户能够自由地选择区块链，而不是要求用户去适应其中一个。这是跨链技术大背景下的必然选择，我们有理由仰望更广阔的天空。

本篇文章如果使用直译，很多地方看着就会很奇怪，主要是英语的表达方式和我们惯用的表达方式不同。所以在这里想再解释下标题，这个标题有点儿驴唇不对马嘴的感觉，通读全文才能比较好理解。标题的前半部分是一种意指，整句话其实是ITAM如果在另一个区块链上运行会怎样，然后通过这个设问引出区块链选择自由的主题。不是要讲ITAM上的另一个区块链，而是要讲区块链选择自由的理念以及ITAM在这方面所做的研究和努力。

“选择自由”，被定义为个人决定自己行为的权利。

“区块链”，被定义为一个能够将交易历史记录在有序的数据区块上，通过共识机制跨越众多计算机链接在一起分散的分布式系统。

区块链 +选择

阅读这篇文章的标题，你可能会想，“所谓选择的自由，到底是什么？'”简而言之，就是将上面两个定义放在一起，即用户有权决定他想使用哪个区块链。

让我们直入主题，ITAM Games是一个基于EOS的项目，创建了一个利用区块链技术为用户提供真正的数字资产所有权的平台。但是，我们必须承认，还有许多其他区块链协议，所有这些协议既有其自身的优势，也有其自身的劣势。

区块链协议

在“区块链”的大框架下，我们可以选择许多不同的协议：EOS，以太坊，Tron，NEO，本体等。根据您的选择，您将获得不同的优势，但也需要面对一些劣势。比如，仅仅是各区块链的不同共识机制，从工作量证明（PoW）、股权证明（PoS）到授权委托证明（DPoS），就会对应用产生巨大影响。

例如，EOS（使用DPoS）具有交易速度的巨大优势;然而，这是以不得不依赖21块生产者为代价的，如果21个生产者中有15个同意，他们有权撤销交易。这对某些用户构成了巨大威胁，有些人甚至可能会说它不是“区块链”，因为它过于集中。

另一方面，使用PoW（比特币）和PoS（Ehetereum）的区块链可能更“分散”，因为给予个人更少的权力，使得区块链数据难以篡改。然而，这种优势会产生交易速度极慢的巨大劣势。

零和博弈

此时的区块链技术似乎就像在进行零和博弈游戏一样;当你获得一项收益，就需要通过另一个损失来平衡。最终，截至目前，还没有“完美”的区块链。哎呀，谁能说会有呢？但作为服务提供商，ITAM Games需要尽可能多地满足用户需求，不论他们使用哪种区块链，都尽全力解决消费者的需求。

其中要注意的一件事是，如果不是区块链的影响来自其“分布式”方面。那么，区块链行业社区是否会像分布式一样具有讽刺意味？以太坊拥护者宣扬EOS的缺点，而与此同时EOS拥护者攻击以太坊的缺陷，Tron支持者宣称这样或那样等等。这些现象构成了一个互相攻击的世界现状！

现在，这并不是说它一定是件坏事。如果用户可以选择他们想要使用的内容，就不会出现这样的情况。这就是多协议，跨平台功能至关重要的原因。我们不能因我们个人的喜好，便将其中一项区块链协议凌驾于另一项区块链协议上。

发送电子邮件至Blockchain

我们可以举一个例子，让我们回到互联网刚刚起步的时候，“电子邮件”的技术刚刚开始应用。如果AOL，Hotmail和雅虎关闭其自己的用户群，导致每个服务提供商的用户无法跨服务进行通信，会怎么样？电子邮件技术会成为今天的样子吗？几乎可以肯定不是！

该服务的用户不应因服务提供商的限制而导致其无法充分利用该技术。用户应该能够衡量对他们重要的利弊，来决定选择哪种服务，并且仍然能够获得技术本身的全部好处。

回到区块链，相应的理念也相应适用。假设您正在玩ITAM游戏的RPG游戏，并且遇到价值1000美元的极为罕见的物品。想要在价值降低之前快速出售该商品的用户将更加重视交易速度。然而，如果用户希望安全地持有这个并且没有计划在短期内进行销售，如果这意味着提高了安全性，用户则不会介意较慢的交易速度。

区块选择的自由

每个人都有权要求他们想要的优势，以及他们想要获得哪些优势。作为服务提供商，ITAM Games认识到这种需求和愿望的重要性，并且不怕尝试不同的可用协议。这就是为什么我们通过与Defractal合作在EOS和以太坊之间建立了一座桥梁，并且对未来的跨平台服务也有很大的计划。

EOS MainNet是ITAM Games目前选择连接到ITAM商店的首选，但在我们服务的整个生命周期中，我们将实施不同的协议，为我们的用户提供Freedom of BlockChoice。因为无法保证今天可用的任何区块链协议将在未来10年，20年，50年仍然存在，而且其他更好的区块链协议很有可能在未来发布，我们不会仅限于一个协议。

原文

“Freedom of Choice,” defined as the right of an individual to determine his or her own actions.

“Blockchain,” defined as a decentralized, distributed system wherein which the history of transactions are recorded on a chain of blocks, linked together in an immutable way across numerous computers.

Blockchain+Choice

Reading the title of this post, you may be wondering, “What in the world is ‘freedom of block choice?!’” To put simply, it’s the above two definitions put in one — the right of users to determine which blockchain he or she would like to utilize.

Let’s get one thing straight, ITAM Games is an EOS-based project, creating a platform that utilizes blockchain technology to give true ownership of digital assets to users. However, we must also acknowledge that there are numerous other blockchain protocols out there, all of which have their benefits, but also their own negative factors as well.

Blockchain Protocols

Under the big umbrella of “Blockchain,” there are many different protocols we can choose from: EOS, Ethereum, Tron, NEO, Ontology, etc. And depending on which you choose, there will be advantages gained, but also some aspects that needs to be given up. Just looking at which consensus system the protocol uses has huge effects, from Proof-of-Work (PoW) to Proof-of-Stake (PoS) to Delegated-Proof-of-Stake (DPoS).

For example, EOS (which uses DPoS) has the immense advantage of transaction speed; however, this comes at the cost of having to rely on 21 Block Producers, of whom have the power to reverse transactions if 15 of the 21 agrees to. This poses a grand threat to certain users, and some may even say it isn’t a “blockchain” as it’s too centralized.

On the flip side, blockchains that use PoW (Bitcoin) and PoS (Ehetereum) may be more “decentralized,” as less power is given to individuals so that the blockchain data is immutable. However, this benefits comes at the huge disadvantage of extremely slow speed.

Zero-Sum Game

Blockchain technology at this point in time seems almost as if it’s in a zero-sum game; you can have one gain, but it’s balanced off by another loss. Ultimately, as of right now, there is no “perfect” blockchain. Heck, who’s to say that there ever will be? But as a service provider, ITAM Games needs to satisfy as many users as we can, and quench the needs of our consumers without discriminating against which blockchain protocol clan they fall under.

One of, if not the biggest leverage of blockchain comes from its “distributed” aspect. However, is it not ironic that the community of the blockchain industry is just as distributed? Ethereum enthusiasts calling out EOS for its disadvantages, while EOS advocates disregard Ethereum for its deficiencies, Tron supporters claim this and that, so on and so forth. The status quo is a dog-eat-dog world!

Now, this isn’t to say that it’s necessarily a bad thing. Not if users are given the choice to choose which they would like to use. And this is why multi-protocol, cross-platform capabilities is crucial. We shouldn’t disregard one protocol over another because of our personal opinions; what’s important to me may not be to another.

Email to Blockchain

To give an analogy, let’s go back in time to when the Internet was at its infancy and the technology of “Email” first started. What if AOL, Hotmail, and Yahoo closed its doors to only its own pool of users, and users of each service provider couldn’t communicate across services? Would email technology be what it is today? Most likely (almost certainly) not!

The users of the service shouldn’t fall victim of not being able to fully take advantage of the technology because the service providers are limiting its use. The users should be able to measure the pros and cons that are important to them, choose the service based on the measurement, and still be able to reap the full benefits of the technology itself.

Bringing it back to blockchain, the same concept applies correspondingly. Let’s say you are playing an RPG game on ITAM Games and come across an extremely rare item worth $1,000. A user that wants to quickly sell this item before its value decreases would put more emphasis on transaction speed. However, a user that would like to safely hold this in their possession and has no plans on selling anytime soon wouldn’t mind having a slower transaction speed if it means security is heightened.

Freedom of BlockChoice

Everyone has the right to claim which advantages they would like, and which they would like to yield. ITAM Games as a service provider recognizes the importance of this need and desire, and are not afraid to experiment with the different protocols available. That is why we have created a bridge between EOS and Ethereum by joining forces with Defractal, and have big plans for the future regarding cross-platform services as well.

The EOS MainNet is the selection of choice by ITAM Games to be connected to the ITAM Store at the moment, but throughout the lifetime of our service, we will be implementing different protocols to offer Freedom of BlockChoice to our users. Because there’s no guarantee that any of the blockchain protocols available today will be around 10, 20, 50 years into the future, and there’s high possibilities of other great protocols debuting down the road, we won’t be limiting ourselves to just one single protocol.
