What Is BRC-20?
BRC-20 is an experimental token standard based on Bitcoin Ordinals inscriptions. It writes JSON messages such as deploy, mint and transfer into inscriptions, then indexers interpret those messages to calculate balances.
💡 Simple version: BRC-20 is not a native Bitcoin smart contract. It is token logic written as inscriptions and interpreted by indexers.
BRC-20 vs ERC-20
| Comparison | BRC-20 | ERC-20 |
|---|---|---|
| Network | Bitcoin | Ethereum / EVM chains |
| Execution | Inscriptions + indexers | Smart contracts |
| Complexity | Relatively simple | Highly composable |
| Main risks | Indexer differences, liquidity, fees | Contract bugs, approvals, project risk |
Why Did BRC-20 Tokens Get Speculative Attention?
- They brought token issuance narratives to Bitcoin.
- Early assets were marketed around scarcity and fair minting.
- Communities speculate around names, numbers and mint history.
Risks Beginners Often Miss
⚠️ Many BRC-20 assets are thinly traded. A token can show a price but have very little real buy-side liquidity. “Built on Bitcoin” does not mean “low risk.”
- Liquidity risk: selling may be difficult even if a floor price exists.
- Fee risk: Bitcoin network congestion can make transfers expensive.
- Indexer risk: different tools may interpret balances differently.
- Narrative decay: many inscription tokens may lose volume after hype fades.
- Phishing risk: fake mint pages and fake marketplaces are common.
How Should Beginners Approach BRC-20?
First understand it as an asset experiment on Bitcoin, not a reason to buy. If you experiment, use a small separate wallet, official marketplaces and money you can fully lose.
