This article briefly compares Hyperledger Fabric and. Ethereum from several aspects such as consensus and smart contacts. Keywords—Blockchain, smart contracts. Download scientific diagram | Comparison of ethereum and hyperledger from publication: The Development of Smart Contracts for Heterogeneous Blockchains.

Hyperledger Vs Ethereum : Comparison of Two Strong Blockchain Warriors


Ethereum was created to serve as a decentralized platform for public use, where all developers can contribute. On the other hand, Hyperledger is a private network which uses blockchain technology for enterprise use. Due to its modular architecture, it offers a higher degree of flexibility regarding its use and deployment. This type of architecture was designed to cater exclusively to enterprise blockchain applications.

Participants Ethereum is a public and permissionless network meaning that anyone is able to access, read or write information on the blockchain. In contrast, Hyperledger Fabric is a permissioned network, which means that only certain entities and nodes have access to participation. MSP is a part of the system which issues and validates certificates, and authentication.

Bearing in mind that both projects have different modes of participation, it leads to different ways in which consensus is reached. Private transaction between members Ethereum does not feature any option of issuing private transactions among its members. In this case, a ledger is called a channel and one can be opened to specific members. This means that certain contracts among parties can stay private while others remain transparent, depending on the channel used.

This feature is very important in enterprise scenarios, such as keeping transparency of internal business procedures and privacy of contractual agreements. Consensus Mechanism In Ethereum, consensus over all the transactions must be reached by all the network participants or nodes. This happens regardless of whether a node has participated in a particular transaction or not.

Ethereum has plans of later on switching to Proof of Stake. While Bitcoin may be qualified as a public blockchain that handles money transactions decentralized cryptocurrency. Ethereum and Hyperledger Fabric blockchains are much more than that. We call them blockchains 2. This means they can execute almost arbitrary Turing-complete code that was deployed into the blockchain a computer program of some sort.

So now using our stone metaphor, we have scripts that can be written into the stone and you can execute automatic actions that alter the stone or make calculations. What is Ethereum? Ethereum is a public blockchain created in by a smart guy called Vitalik Buterin. Those applications would comprise of smart contracts. Ethereum can be seen as a open-source platform that runs those smart contracts.

They will be executed exactly as programmed without any possibility of downtime, censorship, fraud or third-party interference. What is Hyperledger? Hyperledger is not a blockchain in itself. Hyperledger is an open-source project and a hub for many blockchain projects under the Linux Foundation umbrella. Some projects that reside under the Hyperledger umbrella are: Hyperledger Sawtooth: developed by Intel.

Uses a brand new consensus algorithm called Proof of Elapsed Time PoET which helps to build networks with a large number of nodes with a small CPU consumption footprint. Supports both permissioned and permissionless blockchain networks. Hyperledger Iroha: made by Japanese developers who originally created this solution for mobile use cases. Designed for simple creation and management of assets. Consists of new chain-based Byzantine Fault Tolerant consensus algorithm. Soon they will release iOS and Android support Hyperledger Indy: Was created to provide independent identity on distributed ledgers.

Private information is never stored in the ledger. With this solution, you will be in control of sharing your identity with others Hyperledger Burrow: is a permissioned blockchain node that executes Ethereum smart contracts code usually written in Solidity. You can specify an amount of gas needed to execute given contract.

To invoke a contract you need sufficient permissions, not coins or tokens. Provides high transaction throughput thanks to the proof-of-stake Tendermint consensus engine. Hyperledger Fabric: developed by IBM. Supports only permissioned networks.

Provides elastic architecture — different components can be plugged in or out to fit the use case. Then, hopefully, it will be easier to choose one over the other in certain blockchain applications. Permissioned blockchains vs public blockchain networks Ethereum is a public blockchain and permissionless network which means that it can be accessible to anyone for both read and write operations. On the other hand, Hyperledger Fabric is a private network aimed at solving problems specific to the enterprise landscape.

Fabric is a permissioned network. This means that only privileged entities and nodes can participate in this decentralized platform. MSP is a component that issues and validates certificates, and later handles user authentication. Private transaction between members In Ethereum there are no means to issue a private transaction between members.

Hyperledger Fabric can have multiple ledgers. A ledger here is called a channel. A channel can be available only to certain members. Certain contractual agreements should stay private. The one node that creates a valid block first will get the reward in the form of an incentive for honest transactions validation.

Nodes which create valid blocks and are rewarded for their work will get less and less rewards over time. This consensus algorithm requires a lot of CPU power. At some point in the not-so-distant future, Ethereum will migrate to a proof-of-stake consensus algorithm. In contrast to that, Hyperledger Fabric in its default setup uses a no consensus algorithm No-op. However, due to its pluggable architecture other consensus algorithms like Practical Byzantine Fault Tolerance can be configured.

Consensus is abstracted away in a component called Ordering Service. Hyperledger vs Ethereum: Cost of execution Every transaction in Ethereum cost some gas, which is the way in which computing resources CPU, storage are valued in Ethereum.

As the Ether value as against national currencies is fluctuating, the gas costs, if expressed as a fixed factor, would also fluctuate. This way computational costs could stay constant to some extent even with high Ether market volatility. This translates to the observation that every transaction invoked on the Ethereum Virtual Machine will cost some real money.

It brings many advantages as it grants its users the ability to make transactions directly with the clients, quickens the process of entering into the contract and lowers the costs of increasing the reliability of data.
