The Climate Warehouse Public Observer Node

A one-stop-shop to learn of and explore the third version of the Prototype

The World Bank has initiated the third phase of the testing and simulation with Chia blockchain platform to run the Climate Warehouse on an interoperable, public, and permissionless blockchain. In earlier simulation phases, the Climate Warehouse was tested on the Ethereum Hyperledger private platform through the blockchain service Kaleido. We recognize the rapid technological innovation in this space and the emergence of new platforms and will continue to assess the opportunities of using emerging technologies and platforms to support transparency and integrity of climate markets.  

To facilitate the understanding of necessary registry functions and data requirements for tracking transactions of units and demonstrate how the information is tracked through the Climate Warehouse, the website provides access to the Climate Warehouse’s Public Observer Node. The Public Observer Node provides an interactive approach for any user worldwide to learn of and explore the third version of the Climate Warehouse prototype

Data, Usage and Technical specifications



The Public Observer Node currently shows test data to illustrate how project and unit related information will surface in the Climate Warehouse once participants upload their data. The Climate Warehouse is built on top of the public blockchain, which means that any data submitted through the operational Climate Warehouse will become an immutable record in the public blockchain.


To view more information on the data fields and definitions, please check the Data Dictionary. The Data Dictionary is a document that provides a list of proposed parameters needed to track emission reduction units, also known as "Mitigation Outcomes (MOs)" in the Paris Agreement, that are traded in voluntary carbon markets or envisaged under Article 6 of the Paris Agreement.




Through the Public Observer Node, users can view how the Project and Unit related information is displayed in the Climate Warehouse, and also explore the details at Project and Unit level by clicking the individual data tabs and rows.

In addition to the Public Observer Node, Climate Warehouse Observers worldwide can run the same software, either locally or in the cloud to access the same data. If run locally, all data can be mirrored into a local MySQL database to power dashboards, analytics, and reports. 


The Climate Warehouse is fully decentralized and peer-to-peer. This means every participant and observer operate their own node, and there is no central server. This provides several benefits to the community using the Climate Warehouse:
