Massbit is a world-class economic incentive infrastructure blockchain to fulfill the dream of decentralization for decentralized finance and Web3 applications. Massbit mission is to become an innovative infrastructure to make DeFi and Web3 development easier, faster and cheaper. We first look to build decentralized APIs and cross-chain indexing. We work with small API providers and validators to form decentralized gateways. Some API providers we are currently working with only only utilize 20% of their capacities while validators or miners only do their work to earn rewards but waste other resources (data and apis). That gives them incentives to work with MassBit to earn more rewards and serve DeFi and Web3 apps avoid better and cheaper. as relying one single entity causes centralization problem and privacy concern. Blockchain indexing is essential to Defi and Web3 development. It does not make sense for every single Web3 developer to build the whole pipeline of running a node, getting, filtering the right data, indexing and serving the data. Because it not only takes a lot of time abut also takes lots of effort to build the pipeline stable and reliable. MassBit provides the infrastructure to index data of different blockchains like Substrate, Ethereum-compatible chains and especially fast blockchains like BSC, Matic and Solana. Developers only do 10% of the work as write the indexing logic to answer questions like "Top NFT last month of this smart contract". And we support indexing logic in different language (Rust, AssemblyScript, TypeScript).
