transactions in parallel, which delivers better performance than serial

execution, and double-spending is prevented by Sawtooth.

5 . To solve supply chain challenges, Hyperledger Grid is designed as

Hyperledger’s supply-chain solution. Grid is an ecosystem of

frameworks, libraries, and technologies that allow developers to choose

appropriate components for building specific business models and is not

a Blockchain framework or an application. A grid feature is the shared

capability of distributed ledgers for cross-industry supply chain solutions

that uphold the best industry practices and standards to boost the

development process providing reference implementations of supply

chain-based data types, smart contract-based business logic, and data

models.

Hyperledger tools/modules

The auxiliary software used for deploying and maintaining blockchains,

examining the data on the ledgers, as well as the tools to design, prototype, and

extend blockchain networks are the Hyperledger tools/ modules:

1. A set of predefined use cases leveraged by a blockchain tool that lets you

compute the performance of specific blockchain implementation that

generates reports on different performance factors, including resource

utilization, transaction latency, and transactions per second (TPS) is

Hyperledger Caliper hosted by the Linux Foundation.

2. Developed for the blockchain ecosystem is an on-demand “as-a-service”

deployment model called Hyperledger Cello, a toolkit that provides a

multi-tenant chain service that works on top of multiple infrastructures,

including container platforms and virtual machines reducing the efforts

required to build, maintain, and terminate blockchains is a blockchain

module.

3 . Designed to develop user-driven Web applications, a blockchain module

used for viewing, deploying, invoking/ querying blocks, network

information, transaction data, chaincodes, and other relevant data stored

in a blockchain ledger is called Hyperledger Explorer.

4. Designed to make blockchain applications and smart contracts more

seamless and convenient, a development framework and toolkit called

Hyperledger Composer provides business-focused abstractions, sample
