# Tech stack

DFract leverages the technology developed by the Lum Network, that is itself based on the Interchain Stack : 

* Cosmos SDK 

> Cosmos SDK is the world’s most popular framework for building application-specific blockchains.\
> <https://docs.cosmos.network/main/>

* Inter-Blockchain Communication (IBC) protocol&#x20;

> IBC is a protocol that allows blockchains to talk to each other.\
> <https://ibc.cosmos.network/main/>

* Proof of Stake

> Proof-of-Stake, the consensus method that Cosmos is built on, is a different blockchain consensus model that is infinitely more energy-efficient than Proof-of-Work.\
