# Chain World underlying blockchain technology deployment

Chain World is based on the social industry's market pain points, combined with the development opportunities of blockchain metaverse technology, and proposes a vision system that is consistent with the value of content producers and consumers, creating a combination of social networking and games. Chain World, the metaverse ecological benchmark of financial integration, will build a Web3 open social metaverse ecology that will serve 1 billion people.

 After careful consideration, the Chain World team finally decided to build on the Binance Smart Chain, a relatively new but very popular and cost-effective public chain based on BSC smart contract. Binance Smart Chain (BSC) is an Ethereum-compatible blockchain that offers the same smart contract functionality but with lower transaction fees; one of the main benefits of Binance Smart Chain is that it can provide users with lightning-fast processing transactions; additionally, BSC has certain innovations in the consensus algorithm. It uses a consensus algorithm called PoSA (Proof of Stake Authority) that combines the functions of the Delegated Proof of Stake (DPoS) and the Proof of Authority (PoA) mechanisms. The second-level block time can establish a high-speed infrastructure for the DeFi protocol on a network of validating nodes. Overall, Binance Smart Chain BSC is an excellent choice for Chain World.

 Chain World's architecture incorporates several technical features of Binance Smart Chain BSC, such as an iteratively updated smart contract system, an acceptance gateway that supports multi-chain and asset riveting, an improved DPoS consensus mechanism, an efficient chain network and high-speed contract virtualization machine, multi-chain connection and transaction verification mechanism to prevent BP/developer from cheating, asset circulation platform that supports t Each technical link and organization has a strong target and logic gene, and many modular and transformed technical solutions or mechanisms are proposed on this basis.
