In February 2023, the OCM Dimensions collection was launched, making use of a number of developments related to the Bitcoin Ordinals protocol. Ordinals facilitated the inscription of high-quality digital artifacts directly onto the blockchain, ensuring their permanent preservation in digital form. 


But OCM Dimensions stood out as a collection for demonstrating the potential applications of Ordinals early on. While Ordinals was still in its infancy, the collection gave the Bitcoin ecosystem – and crypto users more broadly – a glimpse into a bright future for the world’s oldest blockchain network.

What is OCM Dimensions?


OCM Dimensions is a generative 3D art collection by OnChainMonkey that pioneered recursion and parent-child inscriptions on Bitcoin. 


The first 300 pieces in the OCM Dimensions were inscribed onto sequentially ordered satoshis from one of Bitcoin’s earliest blocks—block 78 from January 2009. This choice symbolically linked the collection to the dawn of Bitcoin, reflecting the blockchain's early historical significance. 


The inscriptions were notably marked as "cursed" due to their negative inscription numbers, introducing a unique twist to their identity. Another standout feature of the collection was its on-chain random reveal mechanism activated post-mint, which dynamically unveiled the characteristics of each Dimension, boosting engagement and introducing an element of surprise for the community. 


The project was originally spearheaded by a skilled team including Danny Yang, Amanda Terry, and Bill Tai. The core values of OCM, represented by the acronym !RISE—standing for Respect, Integrity, Sustainability, and Enrichment—underline the commitment to uphold ethical standards and deliver enduring value to their community.

OCM Dimensions Concept


OCM Dimensions was born out of a vision to stretch the capabilities of Bitcoin beyond mere financial transactions and into the realm of complex, high-resolution, interactive digital art. This collection serves as a platform showcasing how art and blockchain technology can intersect, using the robust, secure foundation of Bitcoin to explore new forms of artistic expression.


The Ordinals that make up OCM Dimensions are not only visually compelling but are designed to be fully interactive and responsive. This adaptability allows the art to upscale and modify its resolution to fit different digital displays and virtual environments seamlessly, highlighting the potential for digital art in various technological spaces.

The technical development of OCM Dimensions is a testament to innovative blockchain utilization. The collection uses sophisticated blockchain techniques such as parent-child provenance, recursion, and composability. These methods ensure clear lineage, efficient problem-solving, and the creation of interconnected digital assets, respectively. 


Furthermore, the use of generative coding allows for the efficient reuse of code across different assets, which minimizes the blockchain space needed for each asset to less than 1 kilobyte—a crucial innovation given Bitcoin’s limited block space. The inclusion of popular libraries like p5.js and Three.js into the blockchain work of the collection not only facilitated rich artistic expression but also paved the way for other developers to leverage these tools within the blockchain ecosystem.

Associated Projects


Before the inception of OCM Dimensions, OnChainMonkey marked its territory as a pioneer within the blockchain space, initially launching on Ethereum in September 2021 due to Bitcoin's earlier limitations in handling such complex projects. As Bitcoin's capabilities evolved, OnChainMonkey transitioned and became the first collection of its kind to be inscribed onto the Bitcoin blockchain in early 2023, underscoring a significant evolution in the usability of Bitcoin for managing digital collections. 


OnChainMonkey has also played a crucial role in various social and humanitarian projects. Leveraging its platform and community, it has initiated impactful actions like high-profile rescues and relief operations, embodying its core values through tangible, positive changes in the real world. This project not only showcases technological and artistic achievements but also underscores the potential of digital communities to drive substantial societal impact.

The Future of Bitcoin Ordinals with OCM Dimensions


OCM Dimensions and its associated projects such as OnChainMonkey are emblematic of how blockchain technology is evolving to encompass a broader range of applications.


The transition of OnChainMonkey from Ethereum to the Bitcoin blockchain, complemented by the innovative use of the Bitcoin Ordinals protocol by OCM Dimensions, marks a significant milestone in digital art preservation and blockchain utilization. These collections not only challenge conventional perspectives on the role of cryptocurrencies but also set new benchmarks for digital interactivity and artistic expression. 


The pioneering spirit of the teams behind these projects, coupled with their commitment to social and humanitarian causes, illustrates the potential of blockchain technology to catalyze positive change in society. By leveraging the security, permanence, and innovative capabilities of blockchain, OCM Dimensions and OnChainMonkey are not just creating digital artifacts; they are fostering a community and environment where technology meets humanity, art meets digital permanence, and collective aspirations drive substantial societal advancements. 


This convergence of technology, art, and community outreach sets a promising path for the future of digital collections and their impact on the world.
