Global-Scale Sustainable Blockchain Fabric

ResilientDB is a permissioned blockchain fabric, which easily allows its users to set up a blockchain application.

ResilientDB helps to lay down a client-server architecture where all the servers are a replica of each other. Each client sends its transaction (or a set of transactions) to a specific replica --> primary. The primary replica takes client transactions and runs a consensus protocol among all the replicas. This process ensures that each replica executes the client transactions in the same order.

At present, we employ the PBFT protocol by Castro and Liskov [1998] to achieve consensus among the replicas. We have also designed several efficient BFT protocols (under peer-review), which are not open-source.

The key components of any blockchain application are: clients, replicas, chain, cryptographic constructs, and consensus. ResilientDB is a permissioned blockchain fabric, and hence, its design differs from the crypto-currencies such as Bitcoin and Ethereum. Unlike Bitcoin, where each miner solves a computationally expensive puzzle, and each miner needs some incentives to work, ResilientDB does not have such a requirement. ResilientDB runs the PBFT consensus protocol, which only requires message exchange among the participating replicas, to ensure each replica has an identical state.
