Rotate Signers

Scale IBFT Consensus Algorithm for Broader Participation

The rotate signers service optimizes environments running IBFT consensus and lets you run more than 16 signing nodes within environments.

What it is

Rotate Signers Service

The rotate signers service is an inclusion and optimization service for environments running IBFT consensus. Kaleido caps the active signers limit at 16 to ensure the stability and performance of the algorithm, and as such this service allows for environments with more than 16 signing nodes to achieve equitable participation in the voting and block signing processes. For environments with 16 or fewer signing nodes, the active signer count can be lowered to optimize the algorithm’s threads while still maintaining maximum byzantine fault tolerance.

Choose and Assign the Number of Current Active Signers

This can be trimmed down to maximize efficiency of the algorithm while still maintaining the highest degree of byzantine fault tolerance.

Manage the Number of Signers to be Added and Removed in Each Batch

Multiple signers can be batched into each rotation interval as a way to offer more consistent participation. Alternatively, the rotation pool can be set at the lowest threshold of 1 as a way to offer more prolonged periods of participation.

Set the Rotation Interval Specified in Minutes

Environmental administrators can configure this interval in accordance with agreed upon network mandates. The minimum interval is 5 minutes.

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. Key differentiators are its quick transaction throughput and its modularity, allowing for more innovation and optimization regardless of industry use cases. Other benefits include scalability and security, key pillars of any enterprise application.

Modular & Pluggable

Hyperledger Fabric is a modular blockchain framework that allows you to plug in different components, such as consensus algorithms and membership services, and tailor networks to your needs

Open source

Part of the Hyperledger project of the Linux Foundation, Hyperledger Fabric is an open source protocol that allows the enterprise to build custom applications and limit vendor risks

Security

With a high level of security for enterprise users, Fabric uses a permissioned network to prevent unauthorized access

Benefits of Quorum

Quorum is a blockchain protocol specially designed for use in a private blockchain network, where there is only a single member owning all the nodes or a consortium blockchain network where multiple members each own a portion of the network.

Scalability

Quorum is designed to be highly scalable, with low transaction latencies and the ability to support a higher number of transactions per second than other blockchain protocols. This makes it well-suited for use in high-volume applications.

Security

Quorum includes a number of security features that are designed to protect sensitive or proprietary data, like private transactions that allow network participants to transact without revealing the details of their transactions to the rest of the network.

Flexibility

Quorum is based on the Ethereum protocol and can support a wide range of decentralized applications and smart contracts. It is also highly modular and customizable so that it can be tailored to the needs of specific use cases.

Gas-free transactions

There is no cost required to submit transactions to a Quorum network, unlike Ethereum, which requires the payment of high and unpredictable gas fees to submit transactions.

How it works

How it Works

When using the Istanbul BFT consensus algorithm alongside either the Quorum or Pantheon node clients, the upper benchmark of actively participating signers is capped by Kaleido at 16 in order to ensure stability and performance of your blockchain network. If the number of active signers were to exceed the logical limit, the algorithm would become overstrained due to an untenable number of threads and render your chain unusable. By enforcing a signer limit, Kaleido safeguards against overwhelming traffic that would otherwise suffocate the environment.

However, as a consortium begins to scale and the number of participants in a network exceeds the upper bounds of permitted active signing nodes, there needs to be a mechanism to provide equitable participation in the consensus algorithm’s voting process. For example, imagine a Kaleido environment with 30 nodes all belonging to different organizations where all of whom desired to be signing nodes.

Organizations participating in coopetition-style networks will undoubtedly want, and likely need, to play a part in the signing of blocks and validation of the chain. The rotate signers service exists to accommodate this mandate by allowing one or more nodes to be added and withdrawn from the active signing pool in configurable intervals.

Set the rotation interval specified in minutes

Environmental administrators can configure this interval in accordance with agreed upon network mandates. The minimum interval is 5 minutes. Take an environment with 5 signing nodes, 4 active signers, a batch of 1 and an interval of 5 minutes. This means that each node would only spend 5 minutes during a 25 minute window as a non-singer.

Enterprise 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.

Insurance

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.
