Hyperledger

Introduction

Hyperledger is a community that aims at developing systems based on blockchain, that are open source and are stable with their frameworks, libraries and tools. It consists of various distributed ledger frameworks. It defines modular architecture bringing high grade stability, reliability, security, flexibility and confidentiality and transparency for the systems that it is implemented on.
Established by linux foundation in 2015, it was built for the advancement in blockchain technology across all the industries.As it is a community, it focuses on encouraging a collaborative approach for developing blockchain technologies with open source standards. It supports the implementation of different complex components existing in the ecosystem.

Hyperledger Fabric:

Hyperledger fabric is one of the major frameworks of the hyperledger platform of blockchain technology.It uses smart contracts similar to other blockchain systems, through which the participants send consensus for the trigger of actions and while updating the blocks on the blockchain. The hyperledger fabric is private and permissioned in nature. That makes it different from others in the blockchain system.
Unlike permissionless blockchain networks, it doesn’t risk any unknown identities’ participation in the execution.
All the members of the hyperledger fabric network enrol through a trusted service provider called Membership Service Provider(MSP).
Various MSPs are supportive of hyperledger fabric and it offers various pluggable options. Ledger data can be stored in multiple formats through hyperledger fabric.

Hyperledger Indy:

Hyperledger Indy was evolved majorly to focus on securing the decentralised digital identity management. With the aid of Indy , identity owners have a choice of sharing their data or sharing of specific data, which is mostly personal and confidential.It is a public blockchain network, also called permissioned blockchain, which provides security features, keeping the privacy intact.

Hyperledger Sawtooth:

Sawtooth is a highly flexible blockchain platform. This open source modular platform uses consensus algorithms for implementation of transaction based updates. It mainly resolves the issues that raise under private blockchains.Sawtooth not just creates or broadcast events, it also helps applications to subscribe blockchain related events or
application specific events.It sends back the details of transaction execution to the clients without storing the data, hence promising security.

Hyperledger Besu:

Besu is a hyperledger blockchain project which operates on a public blockchain. It aims at building permission and public network applications, for the requisite projects.It can be executed on Ethereum public or private permissioned network. Hyperledger Besu however does not support key management due to its security concerns. Ethereum compatible wallets can be used for the same.

Hyperledger Aries:

Hyperledger Aries is mainly used for secure messaging for peer-peer interactions through various decentralized systems. It takes help from Hyperledger Ursa for security management. It is an infrastructure that provides a reusable toolkit that is highly interoperable, which mainly aims at transmitting and storing digital credentials and secret management.

Hyperledger Ursa:

Much sophisticated and decent cryptographic implementation is possible with the help of hyperledger Ursa.It focuses on making distributed ledger storage , comparatively safer and easier.It aims at utilising new cryptographic implementation along with the existing cryptographic libraries. Ursa allows blockchain developers to alter the cryptographic schemes with easy configuration changes. Instead of having separate cryptographic protocol for each project it is beneficial , collaborating on a shared library.
Security and cryptography experts come together for shared projects, making the best use of Ursa.

Hyperledger Features:

Hyperledger_icons1

Easy to understand and begin with:

Smart contract Programs can be coded in multiple languages instead of going for other custom languages and architectures, making it easier to work with.

Hyperledger_icons2

Permissioned and private:

A decentralized private network is always better than the public network with no or fake identity. Hyperledger creates a network that is permissioned and private and participants can be added only with authentic identification.

Hyperledger_icons3

Confidential architecture:

Only authentic peers get access to the data and not everyone can access it without permission. This maintains confidentiality at the highest level.

Pluggable options:

A one-size-fits-all approach is not always feasible. Hyperledger has multiple pluggable options that are used as per customization, ensuring customer engagement models run successfully.

Hyperledger aims at building technical communities of blockchain by providing neutral, open-source, customizable, community driven infrastructure.

Hyperledger smart contracts:

Hyperledger focuses on open source and open governance( decentralized) blockchain systems, with innovative and beneficial capabilities across all the sectors and industries.
Smart contracts are the programmable code that triggers an action when the consensus is given by all the peers of the network.
Hyperledger fabric smart contracts are different in a way, that they are written in chain code. This code is initiated by an external application , whenever it wants to interact with the blockchain ledger or wishes to add another block on the blockchain. Majorly chaincode interacts with the back-end compamonet, the database of the blockchain ledger and not the log of transactions happening.
Chain code can be developed in multiple programming languages hence it’s easier to start with implementing hyperledger for the blockchain system.

To conclude:

The hyperledger defines a strong capability to build the non-monetary , highly scalable and stable applications of blockchain, unlike most other blockchain platforms that aim at cryptocurrencies and token. It definitely avoids a lot of political challenges of maintaining globally consistent currency. Also, as it’s easier to work with, a lot of organisations are coming forward to work on hyperledger platforms to implement blockchain technology for their domain of service or product.
