Regen Network

Regen Network is a public-blockchain ecosystem for ecological regeneration — it uses its dedicated chain, Regen Ledger, built on Cosmos SDK, to enable the creation, trading, verification, and retirement of ecological assets (such as carbon credits, biodiversity credits, soil-health credits) in a transparent, science-backed manner. Through its components — including the Regen Registry (a protocol and project registry) and a marketplace for ecological assets — it aims to align economic incentives with ecological outcomes.
