Our vision is to deliver a decentralized database layer to unify access to data. Xuma is currently developing a decentralized NoSQL database for developers which distributes data across Xuma’s global network. Unlike other solutions our database is multi-chain, fault tolerant, censorship resistant, DDOS-resistant, and has zero-downtime. Download our whitepaper to learn more.

Decentralized Database

A database network using key technologies to encrypt, store, retrieve and distribute data across Xuma’s global database network. The Xuma network is a sharing economy that incentivizes consumers and resource contributors.

Proof of Stake

Xuma Masternode and Staking technologies serves as the core engine that powers the network. The two technologies combine to process current and future tasks in our decentralized networks. In return for their participation, the network will compensate for work provided in the form of XMX coins.

Smart Contracts

This feature controls the system and allows consumers to define rules based on our market contract. Our smart contract will be able to work across blockchains and reduce if not eliminate data silos prevalent in today’s systems.

Masternode is an integral component to the overall Xuma network. Xuma network provides key functionality such as security, privacy, and global data distribution network. Anyone can run a masternode. Hosting Xuma masternode will generate additional Xuma for its owner. The current prerequisites to run a masternode inlude (1) 10.000 XMX as collateral and (2) a static public IP address.
