Thinkium Blockchain features: 1. Thinkium takes unique hierarchical way to build a chain network, which can theoretically achieve unlimited scalability through the separation of subchains from the main chain, inheritance of child-chains from their parent-chain, intra- chain sharding, and cross-chain communications. 2. The Aplati tree, a flat tree structure that enables unlimited logical layers and significantly improves cross-chain efficiency. 3. A four-layer stack architecture which makes it easy and flexible for future system extension and upgrade. 4. The Actor-based parallel processing model, which enables high throughputs high complex transaction processing. 5. Dual-coin ecosystem. Thinkium supports subchains to develop their own coins and the corresponding independent eco-systems. 6. Thinkium supports early-stage small businesses to develop their own low-cost, independent single-chains, customized for their own business scenarios.
