ConsenSys & Amazon Web Services Partner To Build Kaleido Business Blockchain Project

AWS Partners with Ethereum Developer Consensys to Build Enterprise-Grade ‘Kaleido' Platform

Cloud computing giant Amazon Web Services (AWS) has announced a partnership with Ethereum design studio Consensys. The partnership is founded on the goal of making enterprise blockchains easier and faster to deploy.

AWS and Consensys announced the partnership on Tuesday at Consensus 2018 in New York City.

The first product of the partnership has already been revealed. AWS and Consensys have combined to build a business blockchain cloud service called Kaleido. Kaleido aims to optimize the onboarding process for enterprise consortium customers – something that’s a major challenge in the space – while simplifying the operation of private blockchain networks.

Amazon Web Services, however, is careful to maintain that the platform is “protocol-agnostic”. AWS doesn’t plan to exclusively support Kaleido. It also plans to continue supporting major enterprise-grade blockchain platforms like Hyperledger’s Sawtooth and R3’s Corda platforms.

It’s no secret that AWS is interested in blockchain technology. We first heard about AWS’s interest in blockchain technology in 2016 when the company announced it was exploring the possibility of working with blockchain startups by offering dedicated technical support and infrastructure for the firms involved.

More recently, AWS announced a new service this past April to provide out-of-the-box blockchain networks based on the Ethereum network and Hyperledger Fabric protocol.

Despite AWS’s previous involvement within the blockchain technology space, their partnership with Consensys is a big deal. As our friends at explained,

“The unit of Amazon has aligned itself with one of the most influential organizations in the Ethereum community.”

Coindesk later cited AWS’s global technical lead for the partnership program, Matt Yanchyshyn, who said,

“We have been following Ethereum closely as it’s what many of our customers have been exploring, especially for enterprise use cases….Working with Consensys will allow us to further understand customer needs and help accelerate their blockchain efforts.”

It’s also not the first time Consensys has tried to launch an Ethereum platform in the cloud. Back in 2015, at Ethereum DevCon 1, the company announced a Microsoft Azure-based Ethereum platform in the cloud. With Kaleido, however, Consensys aims to take the concept further than ever before.

How Does Kaleido Work?

Kaleido allows users to switch between several consensus algorithms, then choose between two packages:

Geth:This is the most popular client for the Ethereum blockchain app platform.

Quorum:This is the enterprise version of Ethereum developed by JPMorgan Chase.

Kaleido will offer a shared IT approach that will allow the platform to deal with changes like defining a new version of a smart contract, among other tasks.

Plus, the platform offers a “state relay” between a private chain (like a chain setup by a group of enterprises) and a public blockchain. This will help enterprises connect their private blockchains to the Ethereum mainnet – something firms are increasingly demanding yet struggling to accomplish.

This state relay system allows users to configure a time interval and, based on the time interval, Kaleido will aggregate together hashes and write those up to the mainnet on the public blockchain. This makes the public blockchain a ledger of last resort – say, if an arbitrator needs to verify data at an independent source.

What Problems Will Kaleido Solve?

Why do we need a platform like Kaliedo? The platform is designed to solve a number of problems facing enterprise users as they seek to integrate with the Ethereum blockchain, including:

  • Enterprises who want to participate in any shared blockchain infrastructure face an array of physical networking and performance challenges regarding how they connect their respective data centers
  • Enterprise users often struggle to onboard members, making it difficult to manage participation in a blockchain consortium
  • The onboarding process can take weeks, although a public cloud can significantly reduce that time
  • Cryptography, consensus algorithms, and governance all add extra layers of complexity to the situation


The partnership between Amazon Web Services and Consensys already appears to be leading to bright things. Stay tuned for more information about the Kaleido platform as it continues to be actively developed.
