ERC-6551: A Comprehensive Overview of the Non-Fungible Token (NFT) Standard

ERC-6551：不可取代代幣（NFT）標準的全面概述

Introduction to ERC Standards

ERC標準簡介

Ethereum Request for Comments (ERCs) are a series of technical specifications that outline standards for the development and implementation of smart contracts and tokenized assets within the Ethereum ecosystem. These standards ensure interoperability, uniformity, and security among decentralized applications (DApps) and smart contracts built on the Ethereum blockchain.

以太坊徵求意見（ERC）是一系列技術規範，概述了以太坊生態系統中智慧合約和代幣化資產的開發和實施標準。這些標準確保了基於以太坊區塊鏈的去中心化應用程式 (DApp) 和智慧合約之間的互通性、一致性和安全性。

ERC-6551: Defining Non-Fungible Tokens

ERC-6551：定義不可取代代幣

ERC-6551 is an ERC standard specifically designed to define non-fungible tokens (NFTs) within the Ethereum ecosystem. NFTs are unique digital assets that represent ownership or access rights to tangible or intangible items. Unlike fungible tokens such as ERC-20 tokens, which are interchangeable and can be divided into smaller units, each NFT is distinct and indivisible.

ERC-6551 是專門設計用於定義以太坊生態系統中的不可替代代幣 (NFT) 的 ERC 標準。 NFT 是獨特的數位資產，代表有形或無形物品的所有權或存取權。與 ERC-20 代幣等可互換代幣不同，這些代幣可以互換並且可以分為更小的單位，而每個 NFT 都是獨特且不可分割的。

Key Features of ERC-6551

ERC-6551 的主要特性

The ERC-6551 standard provides a standardized framework for creating, managing, and transferring NFTs within the Ethereum blockchain. Its key features include:

ERC-6551 標準提供了用於在以太坊區塊鏈內創建、管理和傳輸 NFT 的標準化框架。其主要特點包括：

• Unique Identification: Each NFT created using ERC-6551 has a unique identification that can be directly examined and verified within the Ethereum blockchain. This ensures that each NFT is distinct and cannot be replicated.
• Metadata Storage: ERC-6551 allows for the storage of additional metadata related to the NFT, such as descriptions, images, or any other information that the creator deems relevant. This data provides context and enriches the representation of the NFT.
• Ownership and Transfer Protocol: The standard establishes a clear protocol for transferring ownership of NFTs from one holder to another. NFT transfer transactions are transparently recorded on the blockchain, ensuring the traceability and security of ownership changes.
• Interaction with Smart Contracts: ERC-6551 enables NFTs to interact with other smart contracts within the Ethereum ecosystem. This allows for more complex functionality and deeper integration with DApps, unlocking new possibilities for NFT utilization.

Security and Protection

唯一標識：使用ERC-6551創建的每個NFT都有一個唯一標識，可以在以太坊區塊鏈中直接檢查和驗證。這確保了每個 NFT 都是獨特的且無法複製。元資料儲存：ERC-6551 允許儲存與 NFT 相關的附加元數據，例如描述、圖像或創建者認為相關的任何其他資訊。這些數據提供了上下文並豐富了 NFT 的表徵。所有權和轉讓協議： 該標準建立了一個明確的協議，用於將 NFT 的所有權從一個持有者轉移到另一個持有者。 NFT 轉帳交易透明記錄在區塊鏈上，確保所有權變更的可追溯性和安全性。 與智慧合約互動：ERC-6551 使 NFT 能夠與以太坊生態系統內的其他智慧合約互動。這允許更複雜的功能以及與 DApp 的更深入集成，從而釋放 NFT 使用的新可能性。安全和保護

The ERC-6551 standard also specifies security measures to protect the ownership and integrity of NFTs from attacks or manipulation. These measures help ensure that the ownership of NFTs is secure and cannot be compromised.

ERC-6551 標準還規定了安全措施，以保護 NFT 的所有權和完整性免受攻擊或操縱。這些措施有助於確保 NFT 的所有權是安全的且不會受到損害。

Technical Implementation

技術實施

The process of creating an NFT using ERC-6551 involves determining the metadata to be included, creating a smart contract that adheres to the ERC-6551 standard, and assigning a unique identifier to the created NFT.

使用 ERC-6551 建立 NFT 的過程包括確定要包含的元資料、建立符合 ERC-6551 標準的智慧合約，以及為建立的 NFT 指派唯一識別碼。

NFT transfer involves creating a transaction that moves the ownership of the NFT from the current holder to the new holder. This is achieved by updating the ownership record stored within the smart contract.

NFT 轉移涉及建立一項交易，將 NFT 的所有權從目前持有者轉移到新持有者。這是透過更新智能合約中儲存的所有權記錄來實現的。

NFT management encompasses monitoring and maintaining the metadata associated with each NFT and updating or modifying the smart contract if necessary to accommodate changes in features or functionality. Additionally, implementing robust security measures, such as thoroughly tested smart contracts, security audits, and best practices in privacy key management, is crucial for safeguarding NFTs.

NFT 管理包括監控和維護與每個 NFT 相關的元數據，並在必要時更新或修改智能合約以適應特性或功能的變更。此外，實施強大的安全措施，例如經過徹底測試的智慧合約、安全審計和隱私金鑰管理的最佳實踐，對於保護 NFT 至關重要。

Benefits of ERC-6551

ERC-6551 的優點

The adoption of ERC-6551 brings several benefits to the NFT ecosystem:

ERC-6551的採用為NFT生態系帶來了幾個好處：

• Enhanced NFT Compatibility: ERC-6551 introduces Token Bound Accounts (TBA), which allow NFTs to be combined with other related assets, such as NFTs, tokens, or attributes, into a single profile. This simplifies asset management and transfer across multiple platforms.
• Blockchain Identity Expansion: TBA enables each NFT to have its own identity, allowing NFTs to interact with DApps independently of the wallet that holds them. This can enhance the utility and value of NFTs.
• NFT Verification: TBA stores comprehensive data about NFT transaction history and asset utility, providing proof of ownership and enhancing the credibility of NFTs.
• Increased DApp Interaction: ERC-6551 allows NFTs to interact with various DApps, expanding their value and enabling NFTs to change their appearance and utility. This opens up new possibilities for NFT utilization and innovation.

Implementation and Use Cases

增強的 NFT 相容性：ERC-6551 引入了代幣綁定帳戶 (TBA)，它允許 NFT 與其他​​相關資產（例如 NFT、代幣或屬性）組合到單一檔案中。這簡化了資產管理和跨多個平台的轉移。區塊鏈身份擴展： TBA 使每個 NFT 都擁有自己的身份，允許 NFT 獨立於持有它們的錢包而與 DApp 進行交互。這可以增強NFT 的實用性和價值。NFT 驗證：TBA 儲存有關NFT 交易歷史和資產效用的全面數據，提供所有權證明並增強NFT 的可信度。增加DApp 互動：ERC-6551 允許NFT 與各種DApp交互，擴大其價值並使 NFT 能夠改變其外觀和實用性。這為 NFT 的利用和創新開闢了新的可能性。實施和用例

ERC-6551 has numerous potential use cases in the cryptocurrency industry, including:

ERC-6551 在加密貨幣產業有許多潛在的用例，包括：

• Dedicated NFT wallets for specific portfolios or collections
• Loyalty cards that retain bonuses, airdrops, and rewards even after being sold
• Decentralized IDs that securely store encrypted user data and proof of compliance
• NFTs representing role-playing characters with various equipment and items
• NFTs consisting of multiple nested NFTs
• Social media accounts managed by NFTs, storing user posts and photos
• Wallets collecting rewards from staked tokens, which can be sold separately
• NFTs that contain wallets previously used to lock up tokens, allowing for the sale of those tokens

ERC-6551 with TBA extends beyond art and gaming to encompass decentralized finance, potentially enabling the tokenization of real-world assets, as explored by traditional financial institutions.

適用於特定投資組合或收藏的專用NFT 錢包即使在出售後仍保留獎金、空投和獎勵的​​會員卡安全存儲加密用戶資料和合規證明的去中心化ID 代表具有各種設備和物品的角色扮演角色的NFT 由多個嵌套NFT 組成的社交媒體帳戶管理通過NFT，存儲用戶帖子和照片錢包從質押代幣中收集獎勵，這些代幣可以單獨出售包含以前用於鎖定代幣的錢包的NFT，允許出售這些代幣帶有TBA 的ERC-6551 超越了藝術和遊戲，涵蓋了去中心化金融，正如傳統金融機構所探索的那樣，有可能實現現實世界資產的代幣化。
