一篇长文 讲解了mint NFT的滥用情形
有些NFT发行喜欢放rare items 包装得像抽卡游戏
但是contract导致的伪随机分布可能造成攻击者exploit
也就是说 只mint特定rare item 造成其他人的损失
除此之外 也有攻击者会事先布好bot去mint某些NFT
相信很多人都有过 货币IDO瞬间被机器人抢光的经验
中段则介绍一个NFT launch的技术流程:
Every NFT launch consists, at its heart, of four steps:
Bidding: The sale goes live, and users submit their bids to the operator (can
a smart contract).
Clearing: The operator matches the collected bids against remaining supply,
determines a clearing price, and selects winning bids.
Distribution: Winners can claim their newly-minted NFTs (or receive them from
the operator).
Metadata reveal: The operator reveals the properties of the NFTs.
每次NFT发行都包含四个步骤:
投标:销售开始,用户将投标提交给营运商(可以是智能合约)
清算:营运商将收集的投标与剩余供应进行匹配,确定清算价格,并选择中标
分发:获胜者可以领取他们新铸造的 NFT(或从营运商处接收)
元数据揭示:营运商揭示了NFT的属性
(内文还有各步骤详细介绍,这边就不引用了,可以点阅原文)
最後则是作者想告诉大家的一些结论:
Unexploitable fairness is the most critical property of an NFT launch with
random metadata. Use robust randomness and never reveal the metadata of an
NFT before it has been bought and settled.
不可滥用的公平性是具有随机元数据的NFT发行的最关键属性。使用强大的随机性,在NFT
被购买和结算之前永远不要透露它的元数据。
Race conditions hurt users, both those who participate in the mint and those
who don’t. Use sequential bidding and clearing (e.g., a raffle or a batched
auction) to solve this problem.
竞争条件会伤害用户,包括参与铸造的用户和不参与的用户。使用顺序投标和清算(例
如,抽奖或批量拍卖)来解决这个问题。
Consider cost-efficiency from minute one. Ask if any step that currently
happens on-chain could also happen off-chain to save money for your users.
Off-chain steps can include bidding but also market clearing, assuming users
can establish some degree of trust in the operator. Consider batching in the
reveal phase.
从第一分钟开始考虑成本效益。询问当前发生在链上的任何步骤是否也可能发生在链下
,以便为您的用户省钱。 假设用户可以对营运商建立一定程度的信任,链下步骤可以包
括竞标和市场清算。考虑在揭示阶段进行分批处理。
