要说到最近推上最火热的热点,那肯定是 “ERC-404”,由 Pandora 团队开发出来的新代币标准,尽管不具备正式以太坊基金会提案通过的流程,仅是一个非官方的标准,但 ERC-404 “图币二象性”的设计让许多人感到耳目一新,也带来了一波炒作潮,不只是 Pandora 官方自推的 $PANDORA 同名代币在不到一周内暴涨超过 100X,更带动了一大票项目方抢着发行 ERC-404 标准协议。

本周 Dr. DODO 就带着大家一同了解下 ERC-404 标准到底是个啥?

起源

要介绍 Pandora 就得提到本月初出现了一个叫做 Uniswap Emerald(EMERALD)的新项目,Emerald 为了解决 NFT 流动性问题推出了一套改良版的代币标准,直接将流动性建立在 Uniswap 之上,当你在 Uniswap 买入 1 $EMERAID,得到 1 颗代币的同时你将得到一个 NFT,1 NFT = 1 $EMERAID token(ERC-20),但由于合约漏洞被攻击而多次更换代币合约,目前团队仍在加紧开发修复。而 Pandora 便是从 Emerald 上得到灵感,其三位创始人将 Emerald 合约优化为现在的 ERC-404 代币标准,ERC-404 试图解决传统 ERC-20 和 ERC-721 两大标准之间的鸿沟,通过一种富有创造性的编码方式让二者实现前所未有的共生。

ERC-404

这个被称为 “图币二象性”的设计,其核心秘密就在于损耗编码,ERC-404 巧妙地使同质代币的数量信息和非同质代币的 ID 标识能够共用同一数据结构进行存储,而且还确保了二者的区分性。这就像一个魔术师在不改变牌堆数目的情况下,同时识别出其中特定的几张牌。

ERC-404 带来的映射机制是另一个亮点。它可以在同质代币和其映射的非同质代币之间自然转换,当你出售代币时,对应的 NFT 会被自动销毁反之则会被创造出来。这样不但极大地提高了 NFT 本身的流动性,还能激发无限的交易创意。用户甚至可以 DIY 选择优先烧毁或保留哪些 NFT。

当然,作为一个实验性质的标准 ERC-404 现阶段还存在一些技术缺陷,主要体现在销毁 NFT 时无法明确指明对象这一点上,不过这可以通过一些 Tokenomics 设计如新增稀有度机制来化解。

现状

Pandora 是第一个基于 ERC-404 代币标准的代币,总量 10000 个,2 月 2 日推出至今其市值已接近 1 亿美元。2 月 6 日 Pandora 已过渡到 2/4 多重签名。说到 NFT 必然会提及稀有度以及碎片化问题,Pandora 也不例外,它在每次铸造新的 NFT 时,便被赋予不同的稀有度,它的稀有度有五个等级,便有可能的套利市场这样会促进流动性。

目前除了 Pandora 本身之外也有了许多依据 ERC-404 标准铸造的代币项目,而 OKX Web3 Wallet 上更是单独将其作出一个栏目分类。

笔者观点

在笔者看来 ERC-404 是一个极具开拓精神的实验,他的出现让许多 NFT Fi 项目相形见绌,NFT 流动性问题一直是许多人努力解决的问题,而 ERC-404 的出现直接将这解决方式作成代币标准成功地为原本水火不容的两大标准架起桥梁,也为数字资产领域打开了新的契机,很可能会诞生出更多令人拍案叫绝的创意。

当然作为一个非官方标准,它也隐含着一定的安全风险。我们拭目以待它的后续演进。


The author wants to talk about the hottest topic recently, which must be the new token standard developed by the team. Although the process proposed by the Ethereum Foundation is not formal, it is only an unofficial standard. However, the duality design of the token has made many people feel refreshed and brought a wave of hype. Not only did the official self-promoted token of the same name soar in less than a week, but it also led a large number of project parties to rush to issue the standard agreement. This week, we will take you to understand the origin of the standard. To introduce it, it must be mentioned that a new project named appeared at the beginning of this month. In order to solve the liquidity problem, an improved version of the token standard was introduced, which directly built liquidity on it. When you buy a token, you will get a token contract that has been replaced many times because of contract loopholes. At present, the team is still stepping up development and repair, and it is inspired from the world. Its three founders have optimized the contract to the current token standard, trying to solve the gap between the traditional and the two standards through one. A creative coding method makes the two achieve unprecedented symbiosis. The core secret of this design, which is called the duality of map and coin, lies in the loss coding, which skillfully enables the quantity information of homogeneous tokens and the identification of heterogeneous tokens to share the same data structure for storage, and also ensures the distinction between them. It is like a magician identifying specific cards at the same time without changing the number of cards. The mapping mechanism brought by it is another bright spot. The natural conversion between the mapped heterogeneous tokens will be automatically destroyed when you sell the tokens, otherwise, it will be created, which will not only greatly improve your own liquidity, but also stimulate unlimited trading creativity. Users can even choose which ones to burn or keep first, of course, as an experimental standard. At this stage, there are still some technical defects, mainly reflected in the inability to clearly specify the object when destroying, but this can be resolved through some designs such as adding a rarity mechanism. The present situation is that the first total amount of tokens based on the token standard was launched on March, and its market value has been close to 100 million US dollars. It has transitioned to multi-signature, saying that rarity and fragmentation are bound to be mentioned, and it is no exception. It is given different rarity every time it is cast, and its rarity has five grades, which will make it possible to arbitrage the market, which will promote liquidity. At present, there are many token projects cast according to the standard, and it is even a separate column classification pen. In my opinion, the author's view is a pioneering experiment, and his appearance dwarfs many projects. The liquidity problem has always been a problem that many people have been trying to solve, and the appearance directly makes this solution into a token standard, which successfully bridges the two incompatible standards and opens up new opportunities for the digital assets field. Of course, as an unofficial standard, it also implies certain security risks. We will wait and see its subsequent evolution. 比特币今日价格行情网_okx交易所app_永续合约_比特币怎么买卖交易_虚拟币交易所平台
