Topl

Topl is a blockchain project founded in 2017 and headquartered in Houston, purpose-built for traceability and impact measurement in environmental, social, and governance contexts. The chain uses a UTXO transaction model with emergent sharding and Ouroboros proof-of-stake consensus derived from Cardano; anyone can create tokens and smart contracts to tokenize supply chain commodities and automate agreements. A blockchain-as-a-service offering lets enterprises connect through subscription without running their own nodes.

It targets the lack of verifiable proof behind sustainability claims, where carbon offset allocation and ethical sourcing are hard to audit, replacing isolated databases and paper certification with on-chain records. In July 2024, stablecoin project Plasma acquired all of Topl's assets in exchange for up to 15 percent of Plasma's fully diluted share capitalization, folding Topl's team and technology into Plasma and ending independent development of the ESG chain.
