The Ultimate Guide to Consensus in Hyperledger Fabric

Consensus in Hyperledger Fabric The consensus in Hyperledger Fabric network is a process where the nodes in the network provide a guaranteed ordering of the transaction and validating those block of transactions that need to be committed to the ledger. Consensus must ensure the following in the network Consensus in Hyperledger Fabric Consists of Three Aspects That Includes: Endorsement Ordering Validatio The fabric is built on a pluggable architecture such that developers can configure their deployment with the consensus module that best suits their needs. The initial release package will offer two consensus implementations for users to select from: 1) No-op (consensus ignored); and 2) Batch PBFT

The fabric is built on a pluggable architecture such that developers can configure their deployment with the consensus module that best suits their needs. The initial release package will offer three consensus implementations for users to select from: 1) No-op (consensus ignored); and 2) Batch PBFT Hyperledger Fabric V1 Architecture ●Ledgeris a tamperproof record of transactions replicated across nodes in the network -A blockchain is a decentralized and distributed digital ledger ●Chaincodeis a program that typically handles business logic agreed to by members of the network, so it may be considered as a smart contrac Hyperledger Fabric is intended as a foundation for developing applications or solutions with a modular architecture. Hyperledger Fabric allows components, such as consensus and membership services, to be plug-and-play. Its modular and versatile design satisfies a broad range of industry use cases. It offers a unique approach to consensus that enables performance at scale while preserving privacy

Kafka-based consensus (ordering service) poses a viable fault-tolerant solution for Hyperlуdger Fabric to be used in a production-grade network. Since version 1.4.1, the Fabric introduced the Raft ordering service. With this option, you get a distributed fault-tolerant service, which is easier to set up and maintain The consensus can be at a ledger level (all nodes have to agree) or transaction level (only the transacting nodes have to agree) In case of Hyperledger, consensus is at transaction level, meaning not all nodes need to engage in the consensus mechanism. Only the two transacting parties can engage and arrive at a consensus. Detailed technical explanation of PBFT (practical byzantine fault tolerance) based Hyperledger Fabric consensus is explained in this link Hyperledger Fabric: A Distributed Operating System for Permissioned Blockchains EuroSys '18, April 23-26, 2018, Porto, Portugal •An ordering service atomically broadcasts state updates to peers and establishes consensus on the order of transactions The architecture of Hyperledger Fabric factors out consensus into its own component — the orderer service. This is an unusual feature because it means Fabric can support different consensus.. Hyperledger Fabric has been designed to allow network starters to choose a consensus mechanism that best represents the relationships that exist between participants. As with privacy, there is a spectrum of needs; from networks that are highly structured in their relationships to those that are more peer-to-peer

In this tutorial, you will create a Hyperledger Fabric network that leverages the Hedera Consensus Service Fabric plug-in to use Hedera Hashgraph as the ordering service via the first-network sample. The HCS Hyperledger Fabric network will be composed of two organizations. Each organization will host two peer nodes. The two organizations will privately communicate and transact within a Hyperledger Fabric channel The Consensus Service proof-of-concept use case is providing custom Hyperledger Fabric networks with decentralized consensus on the validity and order of blockchain transactions without the need to configure a RAFT1 or Kafka2 ordering service. Additional use cases include, but are not limited to, financial markets, matching engines (like those used in Uber or AirBnb), or supply chain negotiations (e.g., several competing factories bidding on parts from several competing parts suppliers)

In reality, Hyperledger Fabric consensus is actually a flexible model. Additionally, it comes with a wide range of consensus algorithms, pluggable options, multiple ledger formats, and many more. As you can see, you can customize this platform to a great extent duces some background on blockchain, consensus protocols and Hyperledger Fabric. In Section 3 we provide a high level view of Fabric's new BFT Ordering Service Node, describing the main inter-nal components and their relation to the library.

Consensus Algorithm Which Consensus Algorithm is used in the fabric? The fabric is built on a pluggable architecture such that developers can configure their deployment with the consensus module. Hyperledger Fabric uses a new execute-order-validate architecture, which lets transactions execute before the blockchain reaches consensus on their place in the chain, as illustrated in Figure 2. Figure 2: The transaction flow in Hyperledger Fabric, in which transactions are executed and endorsed first, before ordering them and validating that they do not conflic On the other hand, consensus entails more than just responding on transaction execution, and this distinction is underscored in Hyperledger Fabric by its central position in the whole transaction pipeline, from request and approval to ordering, verification, and pledge. In a word, the consensus is the total authentication of the accuracy of a group of transactions that make up a block Hyperledger fabric uses two types of the consensus protocol. one is Byzantine protocol and another one is crash fault tolerance. As of modular architecture, it uses them as for the problem in the blockchain network. Thus achieve more reliability to the blockchain network It helps with the BFT development as well, since it gives us a chance to hook into Fabric a leader-based consensus protocol and carry those lessons over when writing the BFT plugin. The design document goes over everything we'll need to do in order to make Raft a consensus option for Fabric

Kafka is probably a great thing to happen to the Hyperledger Fabric, due to its high performance. Multiple orderers use Kafka for being in sync, Kafka isn't an orderer in itself. It just connects two orderers with a stream. Even though it supports crash tolerance, it does not offer protection against malicious nodes in the network. An SBFT based solution can help avoid this problem but is yet to be implemented in the Fabric framework. The issue can be tracke In Hyperledger Fabric, consensus is made up of three distinct steps: Transaction endorsement; Ordering; Validation and commitment; Channels allow organizations to utilize the same network, while maintaining separation between multiple blockchains. Only the members of the channel on which the transaction was performed can see the specifics of the transaction. LevelDB vs. CouchDB: LevelDB is the. application which uses BFT consensus. The best variant of BFT is Practical Byzantine F ault tolerance (PBFT). Hyperledger fabric with deterministic transactions can run on the top of PBFT . This paper focuses on a survey of various consensus mechanisms and makes a comparative study of Hyperledger fabric and E thereum Hyperledger Fabric achieves consensus in a different way. It relies on a backend service (known as the ordering service) that intermediates the messages between senders and receivers. This backend service will ensure that all receivers will see messages in same order - it follows that if all receivers see messages in same order, they will perform the same actions/commits etc Hyperledger Fabric Consensus Algorithm at Present - Solo; In reality, the Hyperledger fabric consensus algorithm Solo is mostly a developer's favorite algorithm for experimenting. Furthermore, it only includes a single node and definitely not suitable for production scenarios. Kafka; Kafka is not a Byzantine Fault Tolerant but a crash fault-tolerance consensus algorithm. Here, the leader.
