🌿GreenChain

Every plant has a lineage.
Make it public.

GreenChain is a shared, tamper-evident ledger of plants for local growers. Register a plant, take a cutting, pass it on — and trace any plant all the way back to the seed or the swap it came from.

How the chain works

  1. 1Register a plant. Give it a name, a species, and where it came from. It gets a permanent code like GC-7K2P.
  2. 2Propagate it. Take a cutting or division and register the offspring from the parent. The two are now linked.
  3. 3Trace the provenance. Every plant shows its full ancestry and descendants, plus a fingerprint that changes if any ancestor does.
