Decentralized Storage System

This chapter introduces the proposal of DACS and Sustainable Generation Manager (SGM) to maintain storage availability on Xenea. Also presented is the system architecture and its implementation along with its parameters.

Inside the payload of Xenea, a hash value of the stored data is input. Therefore, the Layer 1 blockchain with the capability to store the hash value along with the NFT contents is required. The proposed system architecture allows for long-term and secure storage of large amounts of NFT content.

Decentralized Autonomous Contents Storage (DACS)

Decentralized Autonomous Contents Storage (DACS) is an architecture for integrating distributed file systems into blockchains. DACS enables sustainable content storage by linking IPFS and other hash-based file systems across multiple nodes on the network. Each DACS node can input a user's NFT content or its payload as transactions onto blocks of Xenea multiply. Users store their NFT content in these nodes without losing their NFT data.

Network design and conditions for DACS nodes

DACS nodes connect storage devices to Xenea and contribute to maintaining the Xenea network; DACS nodes are designed to add only the necessary storage space on Xenea and not increase the unnecessary on the Xenea network, thereby stabilizing the mining process. DACS nodes can acquire storage operating rights and accept additional XENE staking. The amount of staking is proportional to the amount of physical storage in the DACS node.

DACS node operating conditions:

The storage features of the DACS node will be operated under the responsibility of its owner, however, in Phase 1, until the Xenea network is stable and sufficiently decentralized, Xenea will operate the Decentralized Autonomous Contents Storage (DACS) mining pool in the form of cloud mining, as well as the maintenance of the physical storage space of the DACS nodes.

When the number of DACS nodes is sufficiently decentralized to enter Phase 2 or beyond, each DACS node can operate and manage its own physical storage by satisfying the DACS node's operational requirements.

To become a DACS node owner, one must have storage and a collateral XENE. XENE held in collateral will be deducted in the event of a failure of the DACS node's network, depending on the severity of the failure.

The XENE collateral will be returned to the DACS node at the end of the contract term, but may remain as collateral if the DACS node is to continue to operate.
