Positiva, owning a share of real things on the blockchain
How we built Positiva, a system for owning a share of real-world assets as tokens, with the rules enforced by smart contracts on Cardano.
- Shared ownership
- Split into tokens
- CIP-68
- Follows the standard
- On the blockchain
- Rules enforced in code
The idea
Owning a share of a real thing, like a piece of property, should be as simple as holding a token. Positiva makes that work. Each asset is turned into tokens that people can own a share of and the rules for all of it live on the blockchain.
What we built
- The on-chain rules written in Aiken, split across two addresses on purpose so the main record of the asset is kept separate from the tradeable shares. That keeps things safe and clear.
- The off-chain part in TypeScript, which turns the tricky business of creating and splitting tokens into steps that run the same way every time.
- The app around it (a FastAPI and GraphQL backend with a database) that connects the product to the blockchain, with secure logins.
Why it matters
When you turn real assets into tokens, there is no room for mistakes. A bug in the rules is a bug in someone's ownership. So we treated the smart contracts as the serious thing they are: built to a known standard, laid out carefully and made to be something people can trust.
