项目方跑路仿佛在任何行业中都不免出现，有痛点就是有机会，那么在web3区块链行业中，基于密码学以及公开规则合约的信任，能否从ERC721的协议上做优化，从而规避这种情况呢？
5月新出的EIP5058（提案讨论中，以太坊官方还未合并）想实现的ERC721L就是为此设计的，是将所有权和转移权分离的NFT拓展协议。
本文目录：
首先，为小白科普，EIP和ERC是什么关系？
其次，简述核心点：
a：EIP5058的愿景与实现方式，
b：ERC721存在的问题，以无聊猿抵押所有权导致APE空投被闪电贷攻击为例。
最后，穿插分析此EIP的可行性。
常说的EIP和ERC是什么关系？
EIP是什么？
全称 Ethereum Imporvement Proposals(以太坊改进建议), 是以太坊开发者社区提出的改进建议, 是一系列以编号排定的文件， EIP可以是 Ethereum 生态中任意领域的改进, 比如新特性、ERC、协议改进、编程工具等等。
入口：https://eips.ethereum.org/all
ERC是什么？
全称 Ethereum Request For Comment (以太坊意见征求稿), 用以记录以太坊上应用级的各种开发标准和协议(application-level standards and conventions)。如典型的Token标准(ERC20, ERC721)、名字注册(ERC26, ERC13), URI范式(ERC67), Library/Package格式(EIP82), 钱包格式(EIP75,EIP85)。
入口：https://eips.ethereum.org/erc
小结
ERC协议标准是影响以太坊发展的重要因素, 像ERC20, ERC223, ERC721, ERC777等, 都是对以太坊生态产生了很大影响。EIP则可以进一步先观察到行业内的动态，了解什么痛点是当前的瓶颈。因此我每周都在刷最新的EIP，从问题出发去寻找趋势。
总之，虽然两者并不重叠，但是所有的ERC都是EIP，反之则未必。
EIP-5058 想解决什么？
入口：https://github.com/ethereum/EIPs/pull/5058/files
本质上他是ERC721的拓展，让项目方可以对NFT资产，执行锁定而不是转移，他新增函数setLockApprovalForAll()以及lockApprove()，这样一来在锁定期结束之前被锁定的 NFT 不能转移。
对用户而言，资产还在我的账户内，而且到期了或者项目方出问题了，资产也不会损失。 对官方而言，不是恶意黑用户资产的，那就坦坦荡荡的只是锁定防止用户的问题，而不是要求必须转移。 授权对象：可以是第三方，犹如引入监管机构可以一键冻结账户。
这样一来，形成的博弈是让用户即有持有权的同时去发挥其使用权的价值，而项目方也可以以更安全的资产保护来做清白自证。其流动性也可以通过bound NFT来提升
EIP-5058 提案目前会怎样实现？
本质上是对NFT的锁定状态进行管理，让项目方在继承5058实现的NFT项目中，提供锁定即转移的功能，也可以在继承中实现更多功能比如版税等
目前的提案里他封装提供了若干提供方法：
用户授权项目方：lockApprove（许可锁定单个NFT），setLockApprovalForAll（许可锁定该地址下全部NFT） 项目方合约调用：lockFrom（锁定用户的NFT），unlockFrom（解锁用户的NFT
设定锁定期：
