Bitcoin Ordinals launchpad proposes BRC-69 standard to reduce costs by 90%

Bitcoin Ordinals launchpad Luminex has proposed a new standard called BRC-69 aimed at making it significantly cheaper and more efficient to mint Ordinals-based NFT collections on the Bitcoin blockchain. According to Luminex’s technical documentation, BRC-69 uses a mechanism known as recursive inscriptions to “recycle” already inscribed on-chain data, allowing minters to reduce inscription data size and thereby cut costs by more than 90%, depending on collection size and network fees. Under the Ordinals protocol, NFTs are created by inscribing data such as images or text directly onto individual satoshis, which can be costly and blockspace-intensive when collections involve many large images. BRC-69 restructures the process into three or four combined steps—inscribing trait images once, deploying the collection metadata, compiling it, and then minting assets—so that each individual NFT only needs to inscribe a short line of text referencing existing on-chain traits rather than a full image. Frontends that support recursive inscriptions can then automatically render the final images using only on-chain resources, maintaining full on-chain provenance while optimizing block space. Luminex also highlights an on-chain pre-reveal mechanism as a second key feature of BRC-69, enabling Ordinals collections to conduct reveal phases and show final images in a way similar to NFT launches on other chains, but fully on-chain. The proposal addresses two major criticisms of Bitcoin Ordinals—high inscription fees and heavy use of block space—while potentially making large-scale NFT-style collections more practical on Bitcoin. The standard is published on GitHub and can be used via Luminex’s creator tools, lowering the technical barrier for collection creators.
