Fluree announced a new partnership with Ikigai Technologies to provide off-chain data storage for Cardano metadata. The partnered project is named Logosphere. This new project is a cohort project of Project Catalyst.

The ultimate result of Logosphere will be a metadata sidechain for Cradfan that will be built with Fluree’s graph database. It helps Cardano query data more effectively and more precisely from various sources.

New Opportunities for Data-Focused Applications

Working with data is one of the most attractive sections of technology, especially in the blockchain industry. When a product can gather data from various sources and get insight from them, it will be very valuable. Many blockchains are trying to move to this section by gathering off-chain data and processing it in on0chain applications. Cardano is one of them. A new project from Fluree and Ikigai Technologies focuses on this matter. It will result in a metadata sidechain that helps dApps on Cardano.

Logosphere is the name of the new project that focuses on data use-cases in the Cardano blockchain. It helps the projects in this blockchain gather data more precisely and use it practically. Analytical purposes, building data-centric dApps, and cross-app data sharing are some of the use-cases for the new sidechain.


There is currently no standard for off-chain databases. It’s a burden for dApps that need cross-app data sharing and off-chain data analytics. Ikigai came with a proposal to solve this issue. It wants to use Fluree to build a sidechain for dApps. According to the announcement:

“Fluree’s immutable graph database has native support for W3C data standards, making it well-suited for this solution. Transaction metadata in Cardano will be expanded beyond the current 16kB limit, and Fluree will provide an API to allow anyone developing dApps to harness a means of storing extended metadata.”

Accessing off-chain data is one problem, but being sure about its immutability is another. The new sidechain from Fluree and Ikigai assures developers that the gathered off-chain data has the same degree of trust as the on-chain data because it’s a sidechain and can benefit from Cardano features.

The public sidechain will be available in early 2022. Fluree and Ikigai engineers will collaborate with IOHK engineers in this project. IOHK team can surely help these teams work better with Cardano and deploy the sidechain in a way that can help Cardano developers at best.
