Variations in token standards among the leading 10 blockchains and their functions

Token standards are guidelines and protocols that determine the functionality of tokens on a blockchain. Various blockchains implement their own token standards to promote interoperability, security, and efficiency. Below are some significant token standards across the leading 10 blockchains with Turing complete environments, including Ethereum, Solana, BNB, and XRP:

Ethereum Token Standards

Ethereum has established numerous token standards to aid in the creation and management of digital assets. These standards guarantee that tokens can interact with a variety of decentralized applications and services within the Ethereum ecosystem.

1. ERC-20: The ERC-20 standard is the most prevalent for developing fungible tokens on the Ethereum blockchain. These tokens are interchangeable, making them ideal for currencies, staking tokens, and utility tokens. ERC-20 tokens adhere to a defined set of rules regarding token transfers, transaction approvals, and user access to token data.
2. ERC-721: This standard is utilized for generating unique and non-interchangeable NFTs. ERC-721 tokens are frequently employed for digital art, collectibles, and other singular assets. Each token possesses a unique identifier, distinguishing it from other tokens.
3. ERC-777: The ERC-777 standard enhances ERC-20 by permitting more intricate interactions, such as sending tokens to a contract while notifying the contract in a single transaction. It also incorporates features for improved privacy and security, addressing some limitations of ERC-20.
4. ERC-1155: This multi-token standard enables the creation of both fungible and non-fungible tokens within a single contract. ERC-1155 supports batch transfers, which can lower transaction costs and alleviate network congestion. This standard is advantageous for applications that necessitate the management of various token types.
5. ERC-4626: Tailored for tokenized vaults, ERC-4626 optimizes and consolidates the technical parameters of yield-bearing vaults. This standard seeks to simplify the creation and management of vaults that yield returns on deposited assets.

6. DN-404: DN-404, or “Divisible NFT-404,” is an experimental standard aimed at overcoming the limitations of ERC-404 by enhancing the efficiency, scalability, and interoperability of tokenized assets. DN-404 employs a bifurcated approach, utilizing base ERC-20 tokens to represent fractions of NFTs and mirror ERC-721 tokens to represent the actual NFTs. This design improves transaction throughput, reduces costs, and enables cross-chain transactions.

Solana Token Standards

Solana, recognized for its rapid and cost-effective transactions, has created its own token standards to bolster its expanding ecosystem of decentralized applications and digital assets.

1. SPL (Solana Program Library): The SPL token standard is utilized for both fungible and non-fungible tokens on the Solana blockchain. Unlike Ethereum, which has distinct standards for various token types, SPL adopts a unified approach where distinctions are established at the token creation phase. This standard ensures that SPL tokens are compatible with Solana wallets and smart contracts.
2. Token-2022: An enhancement of the SPL standard, Token-2022 introduces new features such as interest-bearing tokens and improved transfer capabilities. This standard aims to offer greater flexibility and advanced functionalities for developers and users on the Solana blockchain.

BNB (Binance Smart Chain) Token Standards

Binance Smart Chain (BSC) has formulated token standards to support its ecosystem of decentralized applications and services. These standards are designed to be compatible with Ethereum’s ERC standards, promoting cross-chain interoperability.

1. BEP-2: The BEP-2 standard is utilized for tokens on the original Binance Beacon Chain, primarily for the native BNB coin and other tokens on the Binance decentralized exchange. BEP-2 tokens adhere to a set of rules that ensure they can be easily traded and managed on the Binance Chain, which is currently being phased out.
2. BEP-20: This standard is implemented on the BSC and is compatible with the Ethereum ERC-20 standard. BEP-20 facilitates the creation of various token types, including utility tokens, stablecoins, and more. BEP-20 tokens can be readily exchanged with BEP-2 tokens, offering flexibility and interoperability within the Binance ecosystem.

XRP Ledger Token Standards

The XRP Ledger, designed for rapid and efficient cross-border payments, has its own standards for the creation and management of tokens.

1. XRP: The native token of the XRP Ledger, XRP is utilized for transactions and serves as a bridge currency for cross-border payments. Unlike other token standards, XRP does not conform to a specific token standard like ERC-20 but is essential to the operations of the XRP Ledger.
2. XLS (XRP Ledger Standards): These standards outline the specifications and protocols for creating and managing tokens on the XRP Ledger. XLS standards ensure interoperability and compatibility within the XRP ecosystem, facilitating the development of various token types, including fungible and non-fungible tokens.

Key Differences

• Interoperability and Ecosystem: Ethereum’s ERC standards are highly specialized and encompass a broad ecosystem, making them suitable for diverse applications but often resulting in increased complexity and gas costs. Solana’s SPL standard is more unified, providing lower transaction fees and quicker settlement times, which is beneficial for high-throughput applications. BNB’s BEP standards are crafted for compatibility with Ethereum’s ERC standards, enhancing cross-chain interoperability. XRP Ledger’s XLS standards concentrate on ensuring interoperability within the XRP ecosystem.
• Transaction Costs and Speed: Ethereum is recognized for higher transaction costs and slower processing times, particularly during network congestion. Due to its unique consensus mechanisms, Solana offers significantly lower fees and faster transactions. BNB Smart Chain also provides reduced transaction costs compared to Ethereum, while XRP Ledger is optimized for swift and efficient cross-border payments.
• Token Types and Flexibility: Ethereum presents a variety of token standards for different use cases, including fungible tokens (ERC-20), non-fungible tokens (ERC-721), multi-tokens (ERC-1155), and hybrid tokens (DN-404). Solana’s SPL standard merges fungible and non-fungible token functionalities within a single protocol. BNB’s BEP-20 standard expands the capabilities of ERC-20, while XRP Ledger’s XLS standards offer a framework for both fungible and non-fungible tokens.

Each token standard is vital to its respective blockchain ecosystems, enabling the standardized and interoperable creation, management, and transfer of digital assets.
