解析区块链之：Polygon 公链 - 知乎

解析区块链之：Polygon 公链 - 知乎切换模式写文章登录/注册解析区块链之：Polygon 公链网诺数据科技Polygon，这也是我们幻塔空间目前部署的公链，也就是说，幻塔空间这个平台是在基于polygon这条区块链上去构建起来的。对于这条区块链，我们务必需要了解一下和这条公链相关的知识以及它的优势和特点，以方便以后我们能够更好的使用幻塔空间。去年开始，公链Polygon(原Polygon)的流通市值从30亿美元增长到目前超过133亿美元，Polygon俨然成为了近期加密资产市场最大的一匹黑马，那么这背后到底发生了什么呢？一、Polygon公链简介去年，2021年，Polygon拿到了多笔天使投资人的投资，这让Polygon 的代币 Polygon 已经跻身全球市值前 20 大加密代币之一。Polygon，前身是Matic，因为在加密市场里，它像黑马一样的出现，所以又被国内行业戏称为“马蹄”。Polygon是一个建立在以太坊上的Layer2扩展解决方案上的公链。和以太坊比起来，Polygon的速度、可扩展性和可用性都更加有优势。作为后起之秀，Polygon着重布局在区块链游戏和NFT领域。这里我再给大家解释一下Layer2 解决方案。Layer 2 ，也就是第2 层解决方案。这是建立在现有区块链之上的协议，旨在解决区块链主网的交易速度和可扩展性问题。Layer 2 解决方案看似除了有着无穷无尽的技术词汇，对于一般的散户投资者来说其实并没有什么太大的关联，其实不尽然，许多DeFi 用户、GameFi 游戏玩家其实在不自觉中都早已使用了layer 2 的解决方案。GameFi、NFT 都将受益于Layer 2 的技术演进。因为幻塔空间做的是艺术品的交易和流转，所以我们使用了Polygon这条公链来搭建我们的平台。二、Polygon的诞生及发展Polygon产生的背景：以太坊公链的尴尬与矛盾。虽然目前全球有很多落地公链，但是真正发展去中心化应用场景的公链几乎不存在。而POW和POS公链，由于全节点参与记录，从而形成了可扩展性问题和性能瓶颈，限制着这些公链的实际效率。其中，最具代表性的公链是以太坊。然而以太坊也有自身的局限性。一方面，以太坊的经常出现网络拥堵，大量交易处于待确认状态；另一方面，以太坊上又积累了大量的价值，不仅仅是以太坊币，还有大量在以太坊上发行的通证。以太坊公链上的总价值是非常庞大的，而这种庞大与其性能、吞吐量之间形成了一种激烈的矛盾。目前，公链的算力和性能是限制着公链实际应用的核心问题。基于这样的尴尬矛盾，Polygon项目才诞生了，它通过建立侧链，将主链上的资产跨链到Polygon链上进行处理。和以太坊比起来，Polygon交易量是以太坊的3倍，而gas费只有以太坊的0.01%。2019年，Polygon通过代币销售，一共筹集了550万美元，并从知名个人和机构筹集了数百万美元。尽管它在技术上仍处于开发状态，其主网已于2020年6月上线。Polygon的出现有效地将以太坊转化为一个成熟的多链系统，也就是区块链互联网。它至少有三个主要优点：能够充分受益于以太坊的网络效应、本质上更安全、更加开放和强大。我们还需要介绍一下Polygon公链的创始人，他曾是印度一位钻石工厂工人的儿子，曾经住在印度古吉拉特邦，艾哈迈达巴德郊区的一所小房子里，经常为付不起学费而痛苦挣扎。他当时的抱负是找到一份体面的、有薪水的工作，以帮助偿还父亲的债务。不过，命运显然为 Polygon 的联合创始人兼首席执行官安排了更好的方向。Polygon 是一个在印度诞生的区块链协议。创始人在创立这个项目之前一度负债累累，他也从没想过自己会创办一家价值十亿美元级别的公司。创立项目之初，创始人们是从对以太坊进行扩容这个解决方案开始入手的。当时的解决方案是建立在 Plasma 上的。当时每个人都希望在以太坊之上打造一个 Plasma 扩容解决方案，但是以太坊社区转向了多种不同类型的扩容解决方案，这些解决方案都拥有更多的研究者和更高的曝光率。另一个问题是因为他们是从印度开始创业的，他们没有大型风投的支持——两个创始人都没有印度理工学院毕业生的光环。因此，他们不会立即得到 VC （风投）的关注，尤其是在印度的加密货币领域，这个领域一直存在不确定性。现实如此，创始人他们不得不砥砺前行。如果没有上述不利因素，像他们这样的项目可能早就已经筹集到 5000 万美元或者1 亿美元的融资，然后开始高歌猛进了。但现实还是残酷的，没有资本的支持，几位创始人不得不脚踏实地去努力。他们利用现有的优势，想到去找到一种方法来支持上面提到的这些以太坊多种扩容解决方案。因为，他们拥有的应用比该领域的任何人都多。他们还让从事类似工作的另一位专业人士成为了polygon的联合创始人。2021年2月，Matic更名为Polygon。三、Polygon项目的运营情况以及能解决的问题Polygon Network 每天进行 500 万笔交易，以太坊每天进行 170 万笔交易。Polygon 是一个可扩容的网络，交易吞吐量会更多，但它现在已经是以太坊的 3 倍。 Polygon 项目的实际网络是去中心化的，甚至是创始人也无法控制，因为它由世界各地的数百个验证器和网络运行。如果你想关闭或改变任何东西，你办不到——这就是它的美妙之处。目前Polygon是全球性的项目或平台，甚至联合创始人也在世界各地。对于国外的创业公司或者初创项目来说，构建整个企业和一切的前提方式是：它不受政府监管行为的影响。和我们的政府不同，国外的政府更像吸血鬼。目前，Polygon上的流通代币估值约为 140 亿美元，占平台代币总供应量的 60%。在用户方面，Aave 是 Polygon 上推出的最大 DeFi 应用之一，与在以太坊的 26,000 名用户相比，在 Polygon 上拥有 30,000 多名用户。总的来说，在 Polygon 上，有接近 100 万个唯一地址，占到今天以太坊地址的 30-50%，因为单凭借能够扩容平台这一点就足以吸引到更多的新用户。然后我们来说一下Maitc。Matic是基于以太坊发行的ERC 20执行标准，我们也可以把它看成Polygon的链上代币。目前，Polygon每年对验证者和授权者的注册奖励约为12%。虽然这两个实体都没有最低股份，但验证者必须有足够的Polygon才能进入前100名，且所有Polygon代币都将被锁定21天，如果验证者行为不当，则会被剔除。Polygon的钱包也被用于支付Polygon网络的使用费以及Polygon未来开发所需的费用。其低手续费与兼容以太坊的特性已经使以太坊的的那些比较流行的DeFi协议在Polygon上进行部署，这些协议目前锁定的总价值接近50亿美元。Polygon这个基于以太坊的区块链互联网应用能够做到减轻以太坊这个平台的算力负担，不至于拥堵，同时还能够让信息透明公开，实现共享，便于查阅。对此，Polygon创始人用印度的国家网络举了一个例子。假如，在印度马哈拉施特拉邦的一家餐馆需要查询餐馆里的从业人员是否都接种了新冠疫苗。有两个选择，一是政府可以推出一个网页，可以在其中放置接种卡或其他证明材料，然后可以通过扫描获取信息。但印度的政府必须维护这个应用的运行，但巨大的流量和运营成本就会让政府的官网不堪重负。但是在Polygon上，一旦把这个功能加在上面，将其放在区块链上进行检验，是否接种了疫苗就一目了然，并且无需耗费政府网络的算力。对于Polygon的创始人来说，能够为以太坊进行扩容是他们推广自己项目的卖点。尤其对于公共产品数据来说，政府有很多可以用于公共产品的数据。这些可以放在区块链上，像印度这样的国家可以从中受益匪浅。最后，在这里说一段和创始人相关的逸闻。创始人的家人，在他开始创业之初，由于区块链的概念过于抽象，看不到实物和实际利益，所以他们并不了解 Polygon。创始人的岳父母曾以为他在干违法勾当，甚至怀疑他是个法外狂徒。直到新闻媒体开始报道Polygon，直到Polygon成为被广泛使用的公链，他的家人们才能够确定他是在干正事。这种不了解就容易恐慌的心态想必在座的各位多少都曾有过。但是学习和了解能够解决一切恐慌，希望大家能够通过今天的课程，对我们幻塔空间使用的Polygon公链有个全新的认知。在云南省发改委、云南省数字经济局、云南省区块链中心以及五华区管委会的领导和支持下，我们网诺科技将在2022年继续践行复兴中华文化的职责和使命，提供数字化平台运营服务，给平台3.0时代的数字艺术品交易进行赋能，构建可持续发展数字经济交易生态。发布于 2022-03-18 14:27区块链(Blockchain)数字货币公链赞同 229 条评论分享喜欢收藏申请
