MONART CITY · MONART STUDIO VENTURES
Monart City is an interdisciplinary urban innovation studio in Ghana, founded in 2019. Our work runs in three strands: security research for systems that must be able to prove their own history, research on combining technologies around real problems, and urban innovation and education with communities across Sub-Saharan Africa. Each card below says how far that piece of work has got and where on this site to look.

Tested in-houseBuilt and tested by our team. Not a third-party audit.
ResearchIdeas and frameworks, written up for discussion.
ProgrammeOngoing work with people and communities.
StoryEvents and reports from our work.
Our main technical project, and the parts of it you can check from your own browser.
A signature proves a record is genuine, not that the history around it is complete. CELA makes a recorded history tamper-evident, so a missing, reordered or rewritten step can be detected.
Status: seven of eight claimed security properties held in our own adversarial testing; two of those depend on how a deployment is set up. Post-quantum signatures for the history itself are planned.
The pages and files of monartcity.xyz are listed in a manifest signed with a classical (ECDSA-P256) and a post-quantum (ML-DSA-44) signature.
Check it: run the one-click verification in your browser. The page also has a post-quantum migration readiness assessment.
The public edition of the v3 whitepaper: what is built, which properties were tested and with what result, the limits of that evidence, and how to test CELA independently.
Get it: read it online or download the PDF. The full technical edition is shared under agreement.
A 3D view of every CELA layer, from the hardware source and host services to the signed history, the website signature and the Bitcoin anchor.
Check it: your browser verifies the snapshot against the site signature and re-checks the Bitcoin anchor with public block explorers. It shows the last manual refresh, not a live feed, and says how old it is.
How we think about technology, and what we follow.
Our definition of Constructive Technology: combining AI, blockchain, Web3 and hardware around one problem instead of using each in isolation. Also the open community report and the research that led to CELA.
Headlines we follow on quantum computing, AI and security, with global, Africa and Ghana coverage. Selected from outside sources, not our own results.
Where the studio started: education, sustainable building and community work.
Who we are and what we work on: digital infrastructure, urban technology, regenerative architecture and sustainable housing, community development, and policy research.
Our youth and education initiative: courses in regenerative architecture, cultural assimilation and community engagement, run with partner organizations.
Reports from DASA 2025, where we presented real estate tokenization and digital inclusion across Africa, and from the ESO Forum 2025 in Ghana.
Internships and volunteer roles for people who want to help build programmes, stories and partnerships. Leadership roles are still being defined.
