Public Ethereum Tether

Pin State Proofs From Your Private Chain to Public Ethereum Networks

Kaleido’s public Ethereum tether helps increase the immutability of your blockchain networks by pinning your Kaleido chain to the Public Ethereum network.

What it

Public Ethereum Tether


What it is

Pin state proofs from your private chain to public Ethereum networks for ultimate immutability.

Pinning your Kaleido chain to the Public Ethereum network gives you history re-write protection from thousands of public Ethereum nodes, while retaining the privacy of a private chain. The Kaleido Public Ethereum Tether pins your Kaleido chain by writing immutable checkpoint block hashes at regular intervals, with individual signatures from your nodes.

You also have the option to pin your Kaleido chain to a Rinkeby Testnet to test your smart contract solutions without paying fees.

Public Pinning Made Easy

The Kaleido Public Tether service supports sending the state hash reports to the Ethereum MainNet, or for testing purposes, one of the test networks where free Ethers can be acquired.

Full Control of Your Account, Keys and Ether Balance

Once you fund your Kaleido Ethereum public account, you supply the Ethereum account used by the service via a secured workflow, and maintain full control of the private signing key. As a result, you can manage the account in exactly the same way as with a regular cryptocurrency wallet.

Configurable Reports and Flexible Transaction Intervals

You can freely control the service to start and stop sending the state hash reports, and change the interval of sending reports, based on the business needs and to accommodate transaction volume fluctuation. For example, if you need high transaction throughput, you’ll want to tether every hour, and when fewer transactions are necessary, you can reduce your transaction intervals to daily.

Hyperledger Fabric at a glance


Built for permissioned networks


Data isolation and strict governance enabled by Hyperledger Fabric certificate authority

Transaction Flow

Unique Execute-Order-Commit endorsement model where transactions are initially executed on a set of peers while ordering service handles packaging and delivery.

Consensus Algorithms

Consensus protocols such as Solo, Practical Byzantine Fault Tolerance (PBFT), Raft or Kafka (to be able to use several ordering nodes) can be plugged in.

Smart Contract Language

Go, Java, Node.js

What Is Hyperledger Fabric?

Since launching in 2015, Hyperledger Fabric has been a top choice for enterprises looking to build apps on permissioned blockchain networks. The modular architecture is capable of powering large-scale applications that require enterprise-grade data security.

The ability to protect certain details of peer transactions has made Hyperledger Fabric a go-to protocol for industries like financial services, supply chains, and the insurance industry. It works for complex use cases that involve personally identifiable information and proprietary business data.

Hyperledger Fabric is one of the many protocol choices available on Kaleido. With a full suite of plug and play services, flexible cloud deployment options, and powerful APIs, Kaleido is the easiest way to run a Fabric network anywhere.

Benefits of Hyperledger Fabric

Hyperledger Fabric is an open source project designed to handle enterprise-grade use cases. A key differentiator is its quick transaction throughput. Developers choose to build applications with Hyperledger Fabric because of its modularity. It’s flexible, allowing for more innovation and optimization regardless of industry. Other benefits include scalability and security, key pillars of any enterprise application.

Better performance

One click is all it takes to deploy Ethereum nodes in the Unlike other private networks that require every peer to execute transactions and maintain a full ledger, Hyperledger Fabric allows for more delineation of roles among members

Open source

Part of the Hyperledger project of the Linux Foundation, the architecture of Hyperledger Fabric allows for scale and performance

Permissioned network

Developers can build subnets or channels to keep certain transactions and data private while maintaining a shared ledger

Our Hyperledger Fabric Expertise

Jim Zhang is the Co-Founder and Head of Protocol Engineering of Kaleido. He has been involved in the permissioned blockchain space since early 2016, starting with the development of Hyperledger Fabric 1.0 as a committer and responsible for the node.js SDK and the node.js chaincode engine. Jim was also the creator of the Fabric connection profile which is a critical component for various client SDKs to function.

How it works

How it Works

The Public Ethereum Tether is an environmental utility service that allows for synchronized views of the chain, designated via a block hash, to be signed by each node and periodically (based on a specified configuration) relayed to a public Ethereum network. This subsequently creates an irrefutable state proof of the private network at that point in time.

Counter against collusion and add assurances to the historical finality of confirmed transactions by appending collectively signed state proofs of a private Kaleido chain to a public Ethereum network.

The public Ethereum blockchain network, a.k.a the “MainNet,” is a highly secure system to store immutable data. Thanks to the large number of fully decentralized nodes (20,000+) operating on the network and its proof of work consensus implementation, it is very improbable to revert a confirmed transaction.

This makes Ethereum MainNet the ideal place to store the root hash of a permissioned blockchain state so that any attempt to rewrite historical data (such as by a compromised or malicious participant) in the blockchain or its state database will be readily detectable.

The main benefit to considering state pinning stems from the fact that permissioned blockchains are more susceptible to collusion than Ethereum MainNet, due to the much smaller number of “signing” nodes whose digital signatures on blocks are used to provide immutability.

Web3 Use Cases
Run Better on Kaleido

Hyperledger Fabric is a private blockchain that allows developers to create subnets, or channels, meaning that certain proprietary or personal information can remain confidential. This makes Fabric a protocol of choice for industries like financial services, insurance, and supply chain management.

Supply Chains

Hyperledger Fabric networks can increase transparency and traceability of transactions within the network. This transparency can be used to monitor real-time location data, limit fraud and counterfeit goods, and track ESG efforts.

Digital Assets

Complex multi-party business networks built on Fabric can easily tokenize assets, transact instantly, share data, and eliminate cumbersome paperwork as financial business flows are automated.


Moving insurance transactions to blockchain can eliminate fraud, automate claim processing, and digitize legacy systems. Hyperledger Fabric also allows stakeholders to automate Know Your Customer (KYC) processes via smart contracts.
