The document discusses the differences between Hyperledger and Ethereum, two leading blockchain platforms with distinct use cases and target audiences. Hyperledger is designed for private networks and business applications, while Ethereum serves public decentralized applications using smart contracts. It highlights key distinctions in purpose, confidentiality, consensus mechanisms, and programming languages relevant to professionals considering blockchain certifications.

Hyperledger Vs Ethereum: A Dubious Choice
The year 2018 is just a few months away from coming to an end. It has been a
year popular for things like matcha to sriracha and all things sparkly, and of course
Blockchain. The concept of blockchain technology has taken over every little
space of our lives in some way or the other.

Hence, the rise in demand for Blockchain qualified professionals is also increasing
steadily. This means that there is a surge in certifications in the blockchain space
but the confusion whether one should get qualified in Hyperledger or Ethereum
lingers on. Hyperledger and Ethereum are two of the leading platforms of the
blockchain. Though both are platforms of the blockchain, they’re significantly
different in their use cases and applications.
To understand the differences between these two platforms we need to look at
their definitions and what they imply.

What is Hyperledger?
Hyperledger is an open source development project to benefit an ecosystem of
Hyperledger based solution providers and users. It is focused on blockchain
related use cases that work under a variety of industrial sectors. It is an open
source banner project hosted by the Linux Foundation.

It has multiple frameworks under it.
· Hyperledger Fabric
· Hyperledger Sawtooth
· Hyperledger Iroha
· Hyperledger Indy
· Hyperledger Burrow
Hyperledger Fabric was initially contributed by Digital Asset and IBM. It uses Go or
Java as a programming language, and consensus can be reached in a variety of
ways.

What is Ethereum?
Ethereum is an open source platform that allows developers to build and deploy
decentralized applications using smart contracts which are programmed in the
Solidity language. It is a public blockchain network with its own built-in
cryptocurrency called Ether. Ethereum’s public nature makes it a natural fit for
developers.

Hyperledger vs Ethereum
The most crucial difference between Hyperledger and Ethereum is the way they
are designed and their target audience. Ethereum is targeted towards applications
that are distributed in nature with EVM, smart contract and a public blockchain. On
the other hand, Hyperledger targets businesses wanting to improvise their process
with the aid of blockchain technology. It has a very modular architecture and
provides a lot of flexibility concerning the components you want to integrate or not.

Hyperledger Ethereum
Purpose A private network where read/write access depends on
permission.
A public network where all the peers have
the read/write access.
Confident

It has scope for private transactions and limited
accessibility with encryption keys.
It is transparent with each transaction
visible to all the peers.

It does not have mining. Instead, there is a Pluggable
Consensus Algorithm called the Practical Byzantine
Fault Tolerance (PBFT).
It establishes the consensus mechanism
through mining based on the Proof of

Chaincodes are written in Golang. Smart Contracts are usually written in

Tokens One can create custom tokens via chaincode. One can create custom tokens via Coin
API.
Transacti There are no transaction fees to be paid. A transaction fee must be paid using the

As you can see, the two platforms are not only different in their purpose but also in
consensus mechanism. In Ethereum all the nodes (network participants) are
required to reach consensus over all the transactions. For this purpose, the mining
is based on Proof of Work (PoW.) Whereas Hyperledger allows nodes to choose
between No-op, i.e. no consensus is required instead there is an agreement
protocol called Practical Byzantine Fault Tolerance (PBFT) where two or more
parties can agree on a key in such a way that both influence the outcome. This
way Hyperledger provides greater scalability and privacy.

Moreover, the programming language for both of them is different as well. While
Hyperledger chaincodes are written in the Golang (which was developed by
Google), smart contracts are written in Solidity.
Currently, Ethereum is a more mature platform, functioning since July 2015.
Hyperledger, on the other hand, was launched in July 2017, yet it has picked up its
areas of business quite quickly. Both of them serve a different purpose; hence one
should think through before getting a certification. Industries looking for Blockchain
solutions also have to examine carefully as to which platform suits their needs.
