In this note, we will understand how to systematically set up our own hyperledger fabric network at the component level rather than actually configuring the network. We will understand some of the things and steps to take up for the setup of the entire system. Each organization set up a membership service provider (MSP) and …

There are a set of entities in the distributed fabric network, and each entity must be associated with a unique identity. These identities can be issued by Fabric Certificate Authority (Fabric-CA) or an external CA, and the Membership Service Provider (MSP) manages these identities across the entire network. The identities are issued by the CA, …

In the enterprise world, organizations can be considered legal entities which manage businesses. These organizations are recognized with identities, and these identities are valid across the fabric blockchain network. Each organization defines the following entities: Membership services provider (MSP): Manages users, peers, and administrator identities. Administrator(s): Manages peers, chaincode, etc. Users: Initiate transactions. Peers: Manage …

Fabric Certificate Authority (Fabric-CA) issues the identity to users, peers, ordering service nodes, and all the other components, which requires identity across the network. There are many ways to implement the certificate authority, and one of the ways is a Fabric-CA, and another way is called IDE mixer. The fabric CA is attached to the …

The high-level role and responsibility of the client application are to compose a transaction request and submits it to the peer nodes. Peer nodes send the endorsements asynchronously. After receiving sufficient endorsements that satisfy the endorsement policy, it submits the transaction to the ordering service. In the end, it receives the acknowledgment from the peer …

Peer is a special kind of node responsible for endorsement, verification, and adding a new block into the ledger. Each peer can connect to one or more channels, and these channels are completely disjoint from each other. It means one channel’s information will not mix with another channel and has its own ledger and blockchain, …

The same set of peer nodes such as endorsers and committers can be part of multiple blockchain ledgers, and this is achieved using the channels. The channels provide transaction privacy among the different ledgers. Multiple parallel blockchain services can be executed and managed for better utilization of hardware resources and scalability of the entire network …

The ordering service packages transactions into blocks and to be delivered to all the peers across the network, and the communication with the service is via channels. The ordering service and its configuration has to be included in the geneses block of the blockchain. There are different configuration options for the ordering service include: SOLO, …

This note will compare the transaction flow approach followed in Hyperledger Fabric Blockchain Platform compared to traditional Blockchain Platform such as Bitcoin. In the Hyperledger Fabric Blockchain Platform, transaction flow happens in the following order. It starts with the endorsement of transactions by the endorsing peers, followed by collecting individual transactions from the different clients …
