# Storage of DNN and Minting of the NFT

When a MASTER or MAESTRO training has been completed, the corresponding DNN network (piece of software and associated parameters) will be stored on the interplanetary file system (IPFS) network of the MATRIX Blockchain.

The consequential DNN is then minted as a fractional NFT and stored on Ethereum Blockchain with ownership information based on the contribution by parties involved, i.e., those providing training algorithm/model, datasets, and computing power.
