The world of cryptocurrency evolves at breakneck speed, and recent months have seen a surge in innovation around new token standards. These emerging protocols are reshaping how digital assets are created, managed, and interacted with across blockchains. While some critics argue they're merely experimental or inefficient, others view them as foundational shifts in blockchain functionality.
From Bitcoin-based tokenization to revolutionary NFT enhancements on Ethereum, these standards are unlocking new use cases and expanding the capabilities of decentralized systems. Let’s explore four of the most impactful new token standards making waves in 2025: BRC-20, Ordinals, Taproot Assets, and ERC-6551 Token Bound Accounts.
🔑 What Is BRC-20?
BRC-20 is a fungible token standard built specifically for the Bitcoin blockchain. Unlike traditional smart contract platforms like Ethereum, Bitcoin does not natively support complex programmable logic. However, BRC-20 leverages JSON (JavaScript Object Notation) data inscriptions to enable the creation, minting, and transfer of tokens directly on Bitcoin.
This standard operates through a proof-of-work mechanism and relies on ordinal inscriptions to embed token data into individual satoshis. While BRC-20 tokens do not support smart contracts, they’ve sparked renewed interest in Bitcoin’s utility beyond simple value transfers.
One major advantage? Growing exchange support. For instance, BRC-20 tokens can now be deposited and withdrawn on OKX, signaling increasing institutional recognition.

Why BRC-20 Matters
- Enables token issuance on the most secure blockchain.
- Opens Bitcoin to experimental DeFi and community-driven projects.
- Drives engagement through meme coins and cultural tokens.
Despite concerns over blockchain bloat and scalability, BRC-20 has proven that even a minimalist chain like Bitcoin can host token ecosystems — albeit with trade-offs.
🔖 What Are Ordinals?
Ordinals refer to a groundbreaking development that assigns unique identities to individual satoshis — the smallest units of Bitcoin (1 satoshi = 0.00000001 BTC). This innovation allows users to inscribe these satoshis with text, images, or code, effectively turning them into Bitcoin-native NFTs.
Before Ordinals, NFTs were primarily associated with Ethereum and other EVM-compatible chains. But with Ordinals, collectors and creators can now mint digital artifacts directly on Bitcoin, leveraging its unmatched security and decentralization.
Each ordinal is numbered based on its mining order, enabling true scarcity and provable rarity. These inscribed satoshis can be transferred peer-to-peer using compatible wallets, creating a new layer of digital collectibility.

Key Benefits of Ordinals
- No need for sidechains or bridges — everything happens on Bitcoin.
- Immutable and censorship-resistant due to Bitcoin’s robust consensus.
- Fosters a growing ecosystem of marketplaces, tools, and creators.
While debates continue over whether this use case aligns with Satoshi Nakamoto’s original vision, there’s no denying that Ordinals have ignited creativity within the Bitcoin community.
🌱 What Are Taproot Assets?
Taproot Assets is a protocol designed to scale Bitcoin’s ability to handle diverse digital assets beyond BTC itself. It builds upon the Taproot upgrade — a major enhancement that improved privacy and efficiency — by enabling the creation and transfer of custom assets directly on Bitcoin.
What sets Taproot Assets apart is its ability to bundle multiple asset operations into a single on-chain transaction, reducing fees and minimizing blockchain congestion. Additionally, it integrates seamlessly with the Lightning Network, allowing for instant, low-cost transfers of assets such as stablecoins, loyalty points, or tokenized real-world assets.
This protocol addresses one of Bitcoin’s long-standing limitations: the lack of native support for multi-asset transactions. By solving this, Taproot Assets paves the way for broader financial applications on the world’s most trusted blockchain.
How Taproot Assets Enhance Scalability
- Reduces transaction load through batched asset transfers.
- Leverages Lightning Network for fast off-chain settlements.
- Maintains compatibility with existing Bitcoin infrastructure.
As adoption grows, Taproot Assets could become a cornerstone for enterprise-grade applications on Bitcoin.
📜 What Is ERC-6551: Token Bound Accounts?
On the Ethereum side of the ecosystem, ERC-6551 (Token Bound Accounts) represents a paradigm shift in NFT functionality. Traditionally, NFTs have been static — they represent ownership but can’t act independently. ERC-6551 changes that by turning each NFT into its own smart contract wallet.
With ERC-6551, an NFT can own tokens, interact with dApps, and even accumulate transaction history over time. Imagine an in-game character NFT that earns rewards, buys items, and levels up autonomously — all while being fully owned by a user.
This standard introduces Token Bound Accounts (TBA), where every ERC-721 NFT is linked to a unique contract account. The result? NFTs evolve from passive collectibles into dynamic digital identities or agents capable of participating in the broader Web3 economy.
Real-World Applications of ERC-6551
- Gaming: Avatars that own inventory and earn income.
- Social Identity: Profile pictures that maintain reputation and content history.
- Digital Twins: Virtual representations of physical assets with full transaction trails.
ERC-6551 removes friction between wallets and NFTs, unlocking deeper composability across decentralized applications.
Frequently Asked Questions (FAQ)
What makes BRC-20 different from ERC-20?
BRC-20 operates on Bitcoin using data inscriptions without smart contracts, while ERC-20 runs on Ethereum with full programmability. BRC-20 is simpler but less functional than ERC-20.
Can I send Ordinals using any Bitcoin wallet?
No — only wallets that support ordinal inscriptions (like Xverse, Leather, or Hiro) can properly detect and transfer Ordinals without risk of loss.
Are Taproot Assets compatible with Lightning payments?
Yes! Taproot Assets are designed to work with the Lightning Network, enabling fast and low-cost transfers of non-BTC assets across Bitcoin’s second layer.
How does ERC-6551 improve NFT usability?
It transforms NFTs into active accounts that can hold assets, interact with protocols, and build historical records — turning them into true digital entities.
Do these new standards compete with each other?
Not necessarily. They serve different purposes: BRC-20 and Ordinals expand Bitcoin’s utility; Taproot Assets scales asset issuance on Bitcoin; ERC-6551 enhances NFT functionality on Ethereum. Together, they reflect diversification rather than competition.
Is there risk involved in using experimental token standards?
Yes — newer standards may face security vulnerabilities, limited tooling, or low liquidity. Always research thoroughly before engaging with emerging protocols.
Final Thoughts
The rise of these four token standards — BRC-20, Ordinals, Taproot Assets, and ERC-6551 — highlights a maturing crypto landscape where innovation isn’t limited to new blockchains but extends to reimagining what existing ones can do.
Bitcoin continues to surprise with layers of functionality once thought impossible, while Ethereum evolves beyond basic tokenization into richer digital experiences. As developers build on these foundations, users gain access to more powerful tools for ownership, identity, and financial expression.
Whether you're interested in collecting digital artifacts on Bitcoin or exploring self-sovereign NFT identities on Ethereum, now is an exciting time to dive deeper into what's possible.
