L1 blockchain designed to solve the blockchain trilemma with modular design, subnets (shards) and paralellism. Rubix subnets automatically sync to the mainnet without oracles unlike in other modular chains like Cosmos. Salient features include zero gas fees (subnets can pledge RBT tokens in the backend and offer Web2 like UI with zero gas fees at the front end) due to the unique Bring Your Own Blockspace (BYOB) concept. RBTs are the native utility tokens for the Rubix chain. Validators need to pledge RBTs to secure the network. Demand for RBTs will increase as the number of transactions increase. All except 56 RBTs are mined. The network is currently at Level 4 difficulty. There will not be more than 51.4 million tokens ever. Rubix is designed to enable enterprises and Web2 apps mass migrate to Web3. Rubix should support 1 billion users in 5 years. Several ultra-scale projects like ONDC (first ultra scale p2p ecommerce platform), YMCA healthchain/Educhain (100 m+ global community supported by US$10 bil revenue), Decentralized IDs (10 mn DIDs by mid 24), IRCTC (largest Railway network) and energy tracking are being built on Rubix currently. Rubix did not do ICO or IEO and RBT is carefully designed to be a full blown Utility.
