Opstream
A lightweight Bitcoin-native event stream protocol.

OP_RETURN verified
index rebuilt
Built to make Bitcoin NFTs easier to index, own, and monetize.
Opstream is designed around one simple advantage: state is an explicit event stream. Indexers read clear OP_RETURN instructions, creators get paid by valid operations, and ownership is replayed from addresses instead of fragile UTXO movement.
One address, not the whole chain
Opstream indexers follow the operator address event stream instead of decoding every inscription or tracking every wallet.
Creator fees are part of validity
A canonical mint or transfer includes the operator payment, so creator economics live inside the protocol rules.
Ownership is harder to break
Ownership is replayed from address anchors and protocol events, not accidentally moved by spending the wrong UTXO.
| Point | Opstream | Ordinals |
|---|---|---|
| Indexer | One operator address | Global inscription index |
| Creator fees | Required for valid events | Marketplace policy |
| Fractional NFTs | Native units | Not native |
| Marketplaces | Optional | Often index-dependent |
| Data layer | OP_RETURN JSON | Witness data |
| Decoding | Surface-level payload | Witness decoding |
| Ownership | Address-based state | UTXO-carried item |
The comparison focuses on the default ownership and indexing models.Opstream's goal is not to replace Bitcoin primitives; it keeps the protocol layer smaller by making state transitions explicit, address-anchored, and replayable.
Lightweight by design
Opstream avoids smart contracts, global NFT indexers, marketplace APIs, and external consensus. Bitcoin transaction history is the event log.
Operator event stream
Indexers follow one Bitcoin operator address, parse valid protocol transactions, and replay them in canonical order.
Deterministic transactions
Mint and transfer flows use stable output positions for operator payment, protocol JSON, and ownership anchors.
Rebuildable state
The database is only a cache. Ownership, balances, and collection state can be rebuilt from Bitcoin history.
