Enterprise-Ready Blockchain

Cypherium is a highly scalable and robust smart contract platform. Our hybrid design features a joint Proof-of-Work (PoW) and HotStuff (Also adopted by Facebook's Libra) consensus mechanism that can achieve thousands of transactions per second without sacrificing decentralization. Cypherium also implements a Turing-complete virtual machine for smart contracts that runs on Java, the most widely-utilized and reliable programming language in the world. This enables us to democratize the development of smart contracts and lower the barrier to blockchain adoption for existing enterprise.

About Us

At Cypherium, we're focused on addressing the key shortcomings of existing public blockchain infrastructures, where scalability seems to come at the cost of decentralization in every corner of the ecosystem.

As a result, slower, more centralized blockchain infrastructures have hindered the commercial adoption of distributed ledger technologies. By providing a truly decentralized and scalable framework, combined with an accessible and intuitive user interface, Cypherium lays a comprehensive foundation for developers to create groundbreaking apps capable of transforming the future of business, law, and enterprise solutions. Using a hybrid consensus mechanism that utilizes both Proof-of-Work and HotStuff, our software is designed to achieve commercialization viability by maximizing both decentralization and scalability without sacrificing one for the other. Unlike many second- and third-generation blockchains that abandon Satoshi Nakamoto’s original permissionless, trustless consensus mechanism, Cypherium is built on the valuable innovations of previous blockchains. The platform’s unique consensus mechanism provides unprecedented transaction throughput and contract execution time through HotStuff, while leveraging an ASIC-resistant PoW system that maintains a thoroughly decentralized node election.

How It Works

Dual Chain Structure & Hybrid Consensus

Mining in traditional Proof-of-Work protocols like Bitcoin takes on two related yet distinct functions. First, mining involves electing a leader who is responsible for generating the newest block. The second function consists of verifying the transaction data that exists within the block body. However, there is nothing inherently beneficial about using a single process to complete both of these actions.

Cypherium’s technology separates these two processes into two distinct blockchains in order to improve the efficiency of both. An election chain chooses Proof-of-Work leaders to write new blocks, while a transaction chain uses HotStuff consensus to verify the transaction data within those blocks. Building off Bitcoin-NG and ByzCoin protocols, the Cypherium blockchain is optimized for both on-chain scalability & permissionless mineability through this hybrid approach to consensus.

The leader node (crown) proposes a block and waits to be verified by validating nodes.


If 2/3 of the quorum is reached, the block is accepted into the blockchain.


Following its acceptance, the new block is then broadcasted to all nodes.


Honest, verified nodes will then reject all messages from nodes without PoW.


Cypherium achieves unprecedented scalability by electing the voting committee to separate PoW from the transaction verification process, with bandwidth limited only by the capacity of the individual nodes and latency limited only by the propagation time of the network.



Reduced security threats.  With sophisticated technology in place, the likelihood of Sybil and 51% attacks becomes nearly impossible.


Less waiting.  By utilizing dual action blockchains, users no longer need to wait on transaction confirmation.


Highly scalable.  Cypherium’s joint PoW and HotStuff consensus mechanism enables thousands of transactions per second, making the platform uniquely suited for enterprise.


No minimum fees for smart contracts.  Having eliminated price minimums, businesses of all size can benefit from using the platform.


No fixed block size.  Faster, more adaptable transaction processing allows the technology to scale.

Multi-Level Governance Protocol

Cypherium’s governance is composed of multiple layers, where protocol-level governance and application-level governance are separated. While the protocol layer is decentralized, it has the capacity to support centralized application layers suitable for situations that might require such measures, such as central-bank-issued digital currencies.

Virtual Machine

The Cypherium Virtual Machine revolutionizes smart contract technology with four notable innovations that improve the industry standard for Ethereum Virtual Machine (EVM):

Dalvik Architecture.

Instead of using the existing stack-based architecture, we use the register-based Java Dalvik architecture that was created for the Android OS, which is more lightweight and able to run on mobile devices.

Built-in safety checks.

Cypherium performs Safemath safety checks at the virtual machine level, so vulnerabilities commonly found in EVM can be detected by CVM.

Faster data types.

All EVM data types are based on 256-bit words. The Cypherium Virtual Machine supports native 64-bit integers, which is exponentially faster than EVM.

Fixed-point representation.

Fixed-point representation is part of what enables low-cost, embedded chip-technology in payment cards, which is a crucial part of modern business transactions. Where traditional EVMs lack this technology, CVM does not.

More Features

Distributed Version Control

Upgrading all nodes through the distributed protocol. This serves as the foundation of an adequate governance model.

Duo Sandboxs

With dual sandboxes that are custom made for smart contracts, Cypherium offers one environment for testing and another for deployment to ensure high-level platform security.

Schnorr Signature

Implemented as ED-25519, Cypherium’s digital signature mechanism is faster, smaller, and more reliable than Bitcoin's ECC algorithm.
