什麼是 NFT?ERC-721?ERC-1155?新手 3 分鐘爆紅加密貨幣 NFT 懶人包
要了解 NFT 的運作方式, 也得了解技術協議中的幾個項目:
ERC-20: https://en.wikipedia.org/wiki/Ethereum#ERC-20_Tokens
ERC-721:https://en.bitcoinwiki.org/wiki/ERC-721
ERC-721 vs ERC-20
The most distinctive difference between these two types of tokens is their fungibility.
ERC-20 tokens are fungible. This is the «money-like» standard. Each ERC-20 token is completely the same and has completely the same value as others. It’s like dollars – each 5 dollars bill has a value of 5 USD.
ERC-721 tokens are non-fungible. This is the «things-like» standard. Each ERC-721 token is different from others – it has other characteristics. As Cryptokitties, where every of them is unique.

「ERC721 是什麼?為什麼要了解 ERC721?」2017 年 9 月 20 日由加拿大溫哥華新創公司 Axiom Zen,也就是因謎戀貓(CryptoKitties)遊戲而聲名大噪的新創公司 Axiom Zen 技術總監 Dieter Shirley 正式推出,他是 ERC721 規格標準的作者和主要貢獻者,ERC721 規格標準建立的是一種「不可替換代幣」(Non Fungible Token,NFT),這與目前主流的 ERC20 規格標準建立的代幣不同 。
ERC-1155:
The ERC-1155 Token Standard: Not Just For Gaming
With the new standards defined in ERC-1155, Crypto Items can now be minted and transacted in fungible and non-fungible variations and combinations. So a single ERC-1155 smart contract could mint a series of fungible gold tokens, silver tokens, and palladium tokens, all in one ERC-1155 smart contract.
