What Core is
Core is the application at www.bitcoinuniverse.io. It reads Bitcoin and Dogecoin, and the metaprotocol assets carried on them, and it lets you act on what you own through your own wallet.
Four jobs in one place
Section titled “Four jobs in one place”| Surface | What it answers |
|---|---|
| Explorer | What does this address hold, across every protocol Core reads? |
| Index | What tokens, names, or collections exist under this protocol, and who holds them? |
| Portfolio | What do I own, and what can I do with each item right now? |
| Markets | What is for sale, at what price, and can I actually buy it? |
Activity sits across all four: a record of what has listed, sold, delisted, or moved, dated from when the event happened rather than when a maintenance pass last touched the record.
Who it is for
Section titled “Who it is for”- Collectors checking what an address holds without connecting anything.
- Buyers who want the asset, the price, the fees, and the total in front of them before a wallet asks for a signature.
- Sellers listing, repricing, or delisting an item they hold.
- Developers and analysts who need to know which index answered a question, how far behind it was, and whether a figure was measured or simply not read.
You do not need a wallet to use most of Core. Searching, exploring an address, browsing an index, and browsing a market all work with nothing connected.
What Core deliberately does not do
Section titled “What Core deliberately does not do”Being clear about this is more useful than a feature list.
- Core does not custody anything. Keys stay in your wallet. No asset moves without a signature you approve there.
- Core is not a general block explorer. It has no in-app block list, block detail page, transaction detail page, or UTXO browser. Search recognises a block height, a block hash, a transaction id, and an outpoint, and hands each one to an external block explorer. What Core builds itself is the address view and the protocol asset view. Blocks and transactions explain exactly where the line falls.
- Core does not invent a number. A figure that was not read is shown as a dash. A market that could not be read says so rather than showing an empty table. Reading the numbers is the page that makes this usable.
- Core does not present an unreleased capability as available. A protocol whose execution path is incomplete is browsable and not tradable, and the interface says which. The support matrix is the list.
- Core does not run an exchange. The one figure it does not read from its own infrastructure is the fiat exchange rate, and the interface names the source and the time it was measured.
Where Core sits
Section titled “Where Core sits”The Bitcoin Universe protocol registry records capabilities per product
surface. Core is the surface called main. The siblings that appear beside it
are Wallet, Inscribe, and StampDEX. Each protocol page on this site
lists what the registry records for every surface, so a reader who cannot do
something in Core can see whether another product can.
Inscribe is a hand-off rather than an embedded screen: opening Inscribe from Core navigates to the Inscribe application rather than loading it inside Core.
Chains and networks
Section titled “Chains and networks”| Chain | Network | What Core does with it |
|---|---|---|
| Bitcoin | mainnet | Full explorer, index, portfolio, and market surfaces. 33 of the registry’s protocols. |
| Dogecoin | mainnet | Address explorer and markets for DRC-20, Doginals, and TAP on Doge. All three are behind one feature gate. |
| Zcash | mainnet | Two protocols, Zerdinals and ZRunes, recorded in the registry with read and explore actions only. They are documented at docs-zerdinals-and-zrunes. |
A staging deployment exists for release validation. It runs against its own isolated API lane and never falls back to production data. It is not a place to move real funds.
- Your first five minutes, a guided walk with nothing connected.
- Reading the numbers, the one concept that makes the rest safe.
- The protocol support matrix, before you assume you can trade something.
