The combination of YeeCo blockchain with artificial intelligence, Internet of Things, and 5G technology is expected to promote the development of smart healthcare, smart transportation, smart cities, digital society, and asset tokenization. YeeCo has developed an innovative and high-performance “shard+layer” architecture that adopts full-shard PoW solution and CRFG, YeeCo’s original final deterministic technique, to solve efficiency and security problems in the cross-shard and cross-chain transactions.
