Understanding Bitcoin Ordinals and Inscriptions
The process of adding inscriptions to "satoshis" (the smallest unit of Bitcoin) is called inscribing, similar to minting Ethereum NFTs.
What Are BTC-NFTs?
When inscription data is added to a satoshi, it effectively creates a BTC-NFT.
Key Differences Between BTC-NFTs and ETH-NFTs
- Permanence: BTC-NFTs are stored permanently on the Bitcoin blockchain, while ETH-NFTs only store metadata (e.g., title, author, tags) on-chain—actual content often resides off-chain.
- Decentralization: BTC-NFTs inherit Bitcoin’s security, whereas ETH-NFTs rely on Ethereum’s smart contract infrastructure.
What Is BRC-20?
Introduced in March 2023 by @domodata, the BRC-20 token standard extends Bitcoin Ordinals by embedding token information into inscriptions. Unlike Ethereum’s ERC-20, BRC-20 tokens:
- Cannot interact with smart contracts.
- Are tied to satoshis, deriving baseline value from Bitcoin itself.

Will BRC-20 Tokens Go to Zero?
- Technically possible, but satoshis (1 sat = 0.00000001 BTC) retain intrinsic value—currently ~$0.0003 at $30K/BTC.
- Tokens with high satoshi-to-supply ratios may trend toward zero.
Beyond BRC-20: Emerging Standards
BRC-21 (Cross-Chain Assets)
A bridge protocol locking assets (e.g., ETH) on other chains to mint equivalents (e.g., XETH) on Bitcoin.
ORC-20 (BRC-20 Fork)
An optimized fork adding features like upgradable inscriptions.
Opportunities with BRC-20
- Fresh Start Appeal: Meme-like consensus drivers reignite NFT/Meme hype on Bitcoin.
- Multi-Chain Potential: Compatible with forks like BCH/LTC, expanding use cases.
- Miners’ Incentives: Increased transaction fees supplement block rewards.
- Broad Narratives: Ties to DeFi, Web3, and exchanges fuel speculative interest.
- Unlocking Satoshi Value: Satoshis gain utility beyond microtransactions.
Risks and Challenges
- No Native Security: BRC-20 tokens lack Bitcoin’s decentralized validation.
- Low Entry Barriers: Easy minting floods the market with worthless tokens.
- Chain Bloat: Permanent inscriptions inflate block size, raising storage/transfer costs.
FAQs
Q: Can BRC-20 tokens replace Ethereum’s ERC-20?
A: No—they serve different purposes (simplicity vs. programmability).
Q: How does ORC-20 improve BRC-20?
A: Adds flexibility (e.g., mutable inscriptions) and scalability.
Q: Why do miners support BRC-20?
A: Higher transaction fees diversify revenue beyond block rewards.
