Article first time published onWhat is smart contract in Hyperledger?
Hyperledger Fabric users often use the terms smart contract and chaincode interchangeably. In general, a smart contract defines the transaction logic that controls the lifecycle of a business object contained in the world state. It is then packaged into a chaincode which is then deployed to a blockchain network.
What is Hyperledger blockchain?
Hyperledger is an open source project created to support the development of blockchain-based distributed ledgers. Hyperledger consists of a collaborative effort to create the needed frameworks, standards, tools and libraries to build blockchains and related applications.
Which Hyperledger project is a benchmarking tool?

What consensus mechanism does Hyperledger use?
Hyperledger makes use of the permissioned voting-based consensus from the pool of other consensus named the lottery-based consensus. The operating assumption for Hyperledger developers is that business blockchain networks will operate in an environment of partial trust.
What is an advantage of public blockchain Nptel?
Provides secure and restricted access to the digital identity. Allows central authority to verify identity by sharing the identity data. Provides a logging mechanism to track access to the digital identity.
What is the role of msps in Hyperledger fabric Mcq?
Membership Service Provider (MSP) is a Hyperledger Fabric component that offers an abstraction of membership operations. In particular, an MSP abstracts away all cryptographic mechanisms and protocols behind issuing certificates, validating certificates, and user authentication.
