What Is Hyperledger Fabric?

Since launching in 2015, Hyperledger Fabric has been a top choice for enterprises looking to build apps on permissioned blockchain networks. The modular architecture is capable of powering large-scale applications that require enterprise-grade data security.

The ability to protect certain details of peer transactions has made Hyperledger Fabric a go-to protocol for industries like financial services, supply chains, and the insurance industry. It works for complex use cases that involve personally identifiable information and proprietary business data.

Hyperledger Fabric is one of the many protocol choices available on Kaleido. With a full suite of plug and play services, flexible cloud deployment options, and powerful APIs, Kaleido is the easiest way to run a Fabric network anywhere.

Benefits of Hyperledger Fabric

Hyperledger Fabric is an open source project designed to handle enterprise-grade use cases. Key differentiators are its quick transaction throughput and its modularity, allowing for more innovation and optimization regardless of industry use cases. Other benefits include scalability and security, key pillars of any enterprise application.

Modular & Pluggable

Hyperledger Fabric is a modular blockchain framework that allows you to plug in different components, such as consensus algorithms and membership services, and tailor networks to your needs

Open source

Part of the Hyperledger project of the Linux Foundation, Hyperledger Fabric is an open source protocol that allows the enterprise to build custom applications and limit vendor risks

Security

With a high level of security for enterprise users, Fabric uses a permissioned network to prevent unauthorized access

Benefits of Quorum

Quorum is a blockchain protocol specially designed for use in a private blockchain network, where there is only a single member owning all the nodes or a consortium blockchain network where multiple members each own a portion of the network.

Scalability

Quorum is designed to be highly scalable, with low transaction latencies and the ability to support a higher number of transactions per second than other blockchain protocols. This makes it well-suited for use in high-volume applications.

Security

Quorum includes a number of security features that are designed to protect sensitive or proprietary data, like private transactions that allow network participants to transact without revealing the details of their transactions to the rest of the network.

Flexibility

Quorum is based on the Ethereum protocol and can support a wide range of decentralized applications and smart contracts. It is also highly modular and customizable so that it can be tailored to the needs of specific use cases.

Gas-free transactions

There is no cost required to submit transactions to a Quorum network, unlike Ethereum, which requires the payment of high and unpredictable gas fees to submit transactions.

How it works

How it Works

The Kaleido Block Explorer is an environment-specific console that provides realtime and historical snapshots of the blockchain.

It can be leveraged for both high-level analytics (e.g. chain height, commonly called contracts, transaction rate, etc.) and more granular insights (e.g. block contents, transaction hashes, sending accounts, etc.).

Search Bar

Use the search bar to jump directly to a specific subset of the ledger. The search bar accepts three valid inputs:

  • Block Number: The number of the desired block for inspection. For example, enter 0 to see the contents of the chain’s genesis block. Bear in mind that the Kaleido consensus mechanisms may cut blocks regardless of transaction presence (PoA and IBFT output multiple blocks in a minute). As a result, if you are operating in an environment with low transaction throughput and running PoA or IBFT consensus, a large allotment of blocks will be devoid of transactions.
  • Contract Address: callable address of an Ethereum smart contract deployed within the environment.
  • Transaction Hash: The ID of a specific transaction. A transaction implies that byte code has been executed by the EVM. These include deployments of smart contracts and subsequent invocations.

Blocks

By default, the Block Explorer home screen displays the 25 most recent blocks on the chain. As mentioned above, blocks are minted in accordance with the consensus protocol’s system configuration and do not necessarily contain transactions. Click the block number to see the contents of a specific block. 

Transactions

Transactions are listed chronologically with the most recent transaction at the top of the list. The transaction table exposes truncated values for transaction hash and the sending account. Additionally, if the transaction is a smart contract deployment, it is denoted with a 'New Contract Created' tag.

Enterprise Use Cases
Run Better on Kaleido

Hyperledger Fabric is a private blockchain that allows developers to create subnets, or channels, meaning that certain proprietary or personal information can remain confidential. This makes Fabric a protocol of choice for industries like financial services, insurance, and supply chain management.

Supply Chains

Hyperledger Fabric networks can increase transparency and traceability of transactions within the network. This transparency can be used to monitor real-time location data, limit fraud and counterfeit goods, and track ESG efforts.

Digital Assets

Complex multi-party business networks built on Fabric can easily tokenize assets, transact instantly, share data, and eliminate cumbersome paperwork as financial business flows are automated.

Insurance

Moving insurance transactions to blockchain can eliminate fraud, automate claim processing, and digitize legacy systems. Hyperledger Fabric also allows stakeholders to automate Know Your Customer (KYC) processes via smart contracts.

Common Questions about Block Explorers

What is a block explorer?

A block explorer is a tool that makes it possible to see realtime and historical blockchain data. Block explorers can be leveraged for both high-level analytics on things like chain height, transaction throughput, and smart contract usage, as well as granular insights into things like block contents, specific transactions, and transacting addresses. This makes block explorers a useful tool for monitoring and analyzing blockchains.

How do block explorers work?

Block explorers work by connecting to a specific blockchain and downloading a copy of the blockchain's transaction and block data. The block explorer then indexes this data and makes it searchable and easily accessible to users through a web interface.

When a transaction is made on a blockchain, it is broadcast to the network and included in a block along with other transactions. Each block is then added to the end of the blockchain in a linear, chronological order. The block explorer maintains a copy of the entire blockchain, which allows it to display the transaction and block data to users in real-time as new blocks are added.

Block explorers use various techniques to keep their copy of the blockchain up to date, such as using APIs provided by the blockchain network or subscribing to transaction and block data feeds. Some block explorers also allow users to query the blockchain using specialized search tools, such as by searching for a specific transaction or block by its hash or by looking up the balance of a particular address on the blockchain.

Who uses block explorers?

Block explorers are used by a wide variety of people, including:

  1. Blockchain developers: developers who are working on building applications or services on top of a blockchain use block explorers to monitor their application's performance.
  2. Blockchain users: individual users of blockchain networks use block explorers to track the movement of their tokens and verify the status of their transactions.
  3. Blockchain network administrators: network administrators use block explorers to track the usage of their blockchain network, analyzing trends and highlighting issues.
