The Hyperledger Project Executive Director, Brian Behlendorf has maintained from the inception of the project that it’s just wrong to view the Hyperledger and Ethereum communities as competitive. Ethereum is a public blockchain that allows anyone to join the network, by mining or running a node. On the other hand, Hyperledger is beneficial blockchain framework that is focusing on bringing the benefits of blockchain technology to businesses in a controlled manner. Let’s take a look at some of the critical differences between the two blockchains and see how combining the two can accomplish tasks that were previously impossible.

Ethereum V/S Hyperledger Fabric
All blockchains are not created the same. Public blockchains such as Bitcoin and
Ethereum are decentralized ledgers that anyone in the world can access and use
for transferring digital assets. However, there is a price to pay for the decentralized
processing of transactions in the form of slow transactions and a large number of
wasteful computations.

On the other hand, a private blockchain created using the Hyperledger Fabric
gives limited access to trusted users, typically those who were involved in the
creation of the private blockchain. As a result, such blockchains have much higher
throughput and therefore can perform different order of magnitudes better than
public blockchains.

The best of both worlds : Hyperledger Burrow
Burrow is a permissioned smart contract machine developed by Monax which
executes Ethereum Virtual Machine (EVM) smart contract code on a permissioned
virtual machine such as Hyperledger. Ethereum smart contracts are typically
written in Solidity or Viper and would require no modification to be deployed on the
Burrow smart contract machine.

Monax CEO Casey Kuhlman claims that Burrow provides a modular blockchain
client such as Fabric with an intelligent contract interpreter that can handle EVM
code. Burrow relies on three main components to execute the EVM smart contract
code: the consensus engine, the interpreter and the application engine.

Together, these components bring permissions to Ethereum Blockchain and
before running any code, make sure that necessary permissions have been
granted. Such a combination is useful as it can give public blockchains the
security and reliability of the Ethereum public blockchain without the additional
overheads.

How to deploy EVM smart contracts on Burrow?
Before you’re ready to deploy your smart contract code on Hyperledger, there are
a few prerequisites that you must get out of the way. They include signing up for
IBM cloud and setting up the IBM cloud command line interface. You would also
require docker and Kubectl.

Once you have the basics set up, you need to access the IBM Cloud Dashboard
and sign in. After that, you need to go to the IBM Container Service and create a
Cluster. After the cluster is set up, you need to find its worker nodes and save their
public IP address as it will be required later. You are now ready to interact with
your cluster using Kubectl.

Now, deploying the EVM smart contract to the Fabric VM requires the following
four steps:
· Clone the container service repository. It can be done by running the given
command in your working directory.
– $ git clone
https://github.com/SaifRehman/fabric-evm-ibm-container-servi
ce.git
·

Navigate to the container service directory which contains the scripts required to
deploy the EVM code.
– $ cd fabric-evm–ibm-container-service
· Navigate to script folder.
– $ cd cs-offerings/scripts
12

· Deploy to Fabric with an EVM plugin to the IBM Container Service.
– $ ./create_all.sh
This runs the Ethereum Virtual Machine on Fabric using IBM’s container service
which can now be used to execute any of the smart contract code written in
solidity or viper.
