In a press release published on 9 September, Fluree announced it has partnered with Ikigai Technologies to provide a comprehensive off-chain data storage solution for the Cardano blockchain. The project, called “Logosphere,” will be funded as a cohort project of Catalyst, a Cardano community fund allocated through public voting.

Fluree is a provider of an immutable semantic graph data platform, while Ikigai Technologies is a blockchain company specializing in decentralized infrastructure. Ikigai will use Fluree’s technology to launch “Logosphere” as a public sidechain in early 2022. The company’s proposal centers around using Fluree’s immutable graph database to provide native support for W3C data standards. This will enable transaction metadata in Cardano to be expanded beyond the current 16kB limit, with Fluree providing an API to allow anyone developing dApps to harness a means of storing the extended metadata.

Until now, there hasn’t been an easy way to access the metadata on the Cardano blockchain. Users were required to go through third parties that inspect every transaction and there was no common standard for off-chain databases.

Brian Platz, the Co-CEO and Co-Founder of Fluree, said the fact that on-chain parts of Cardano are immutable, while the off-chain metadata is not, created a real trust problem for the ecosystem. 

“Fluree and Ikigai Technologies will work together to build a sidechain with the ability to link and share data while ensuring the same degree of trust as the on-chain data,” he said in the company’s press release.

The teams will collaborate on Logospehere’s design with engineers from IOHK, the company behind the Cardano blockchain.
