How Bitcoin Ordinals and Inscriptions Actually Work — Practical Tips for Wallets and BRC-20

Whoa! Bitcoin got weird again.

At first glance ordinals look like NFTs on Bitcoin, but that’s a simplification. My instinct said: “It’s just art on-chain.” Then I dug in and realized it’s more about satoshi indexing and witness data than about some neat token standard. Initially I thought inscriptions would be simple, though actually the plumbing is a bit fiddlier once you care about fees, UTXO management, and long-term recoverability.

Here’s the thing. Ordinals attach data to individual satoshis using the SegWit witness space and a convention for numbering sats. That lets you “inscribe” bytes — images, HTML, even scripts — onto a specific sat. The inscription isn’t a new token layer in the base protocol. Instead, it leverages existing transaction structure and a community convention to interpret certain data as meaningful content. On one hand that’s brilliant: you get immutability and Bitcoin’s security. On the other hand it’s messy: wallets need to opt in, indexers must parse transactions, and fees can be unpredictable.

Short story: inscriptions = data in witness + ordinal indexing. Medium story: anyone can inscribe, but the process depends on tooling and miners. Long story, with details: because inscriptions increase transaction weight, they can push fees up during congestion, cause UTXO fragmentation that complicates future coin selection, and require careful custody planning if you want to move or recover an inscribed sat later — and those trade-offs matter depending on whether you’re building collectibles, experimental finance, or just messing around as a hobbyist.

Wallets, Tools, and Getting Started

Okay, so check this out—if you want to store or trade ordinals you need a wallet that understands them. Not every Bitcoin wallet will display or preserve inscriptions. I use a mix of tooling depending on the task: for quick viewing and simple management there are browser extensions and web wallets that parse indexers; for custody and recovery you want a wallet that exports the full PSBT or shows exact UTXO-level details. One convenient place to start is Unisat — they’ve built tooling around ordinals that many users find friendly, and you can check them out here: https://sites.google.com/walletcryptoextension.com/unisat-wallet/.

I’m biased, but wallets that hide UTXO details are dangerous when you deal with inscriptions. Why? Because inscriptions are tied to specific sats. If your wallet consolidates or spends like a normal wallet without indicating which UTXOs hold inscriptions, you might accidentally burn or lose them. Also, some wallets re-broadcast transactions differently, and mempool behavior can affect whether an inscription actually lands where you expect. So watch the UTXO picker.

Fees are another beast. Inscriptions can be small (a few hundred bytes) or large (multi-kilobyte images). The bigger the payload, the more weight, the higher the fee. During market hype you might see fees spike and inscription costs balloon — I’ve paid more than I expected to ensure a timely inclusion. If you’re experimenting, consider batching inscriptions or using smaller payloads.

People ask about BRC-20 tokens. These are a clever hack: they use inscriptions to store JSON-like mint and transfer records that indexers interpret as tokens. They’re not a protocol-level fungible token standard like ERC-20; they’re an application built on-top of inscriptions. That brings power — you can create token-like systems without consensus changes — but also pitfalls: fungibility is imperfect, front-running and mempool manipulation are real risks, and many marketplaces rely on third-party indexers that might go down or diverge.

Security checklist (quick): back up your seed, prefer hardware wallets for custody, avoid wallets that auto-consolidate without warnings, and record which UTXOs contain valuable inscriptions. Also: be wary of “inscribe for me” services that require custody — you’re effectively handing them a private key capability. Somethin’ to remember: inscriptions live on Bitcoin, but they aren’t protected by extra token governance — they’re as secure (or as brittle) as the underlying UTXOs and the tools you use to manage them.

There are UX oddities worth calling out. Indexers disagree sometimes. If a marketplace shows an inscription but your node doesn’t — that’s not a conspiracy, it’s a tooling mismatch. Different indexers parse and display outputs differently, and they may follow different heuristics for what counts as an inscription. So if you’re composing software, build with multiple sources or clear error handling. (Oh, and by the way: test on testnet first.)

On community behavior: Ordinals have drawn artists, speculators, and developers. That mix creates both innovation and noise. Expect clever use-cases — like on-chain games, pay-to-inscribe auctions, and art archives — and expect scams or low-value spam, especially during hype cycles. I’m not 100% sure where this will land long-term, though I suspect inscriptions will remain a niche of high interest to certain communities and use-cases rather than a mass UX layer for everyday payments.
