Enterprise Ready Blockchain

Cypherium is a scalable and robust smart contract platform. Our design features a hybrid Proof-of-Work/PBFT 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.

About Us

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

As a result, slower, more centralized blockchain infrastructures have hindered the commercial adoption of distributed ledger technologies. By providing a truly decentralized, yet scalable infrastructure, together with an accessible and intuitive user interface, Cypherium lays a comprehensive foundation for developers to create groundbreaking apps, and looks towards the future of business, law, and enterprise solutions.

Cypherium is a highly scalable & permissionless blockchain platform, with a hybrid consensus mechanism that utilizes both proof-of-work and Byzantine fault tolerance.

Our software is designed to achieve commercialization viability through 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, we at Cypherium try to build on the valuable innovations of previous blockchains. Cypherium’s unique consensus mechanism provides unprecedented transaction throughput and contract execution time through PBFT, 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, but 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.

Our technology decouples these two processes into two distinct blockchains, improving the efficiency of both. An election chain chooses through Proof-of-Work leaders to write new blocks, and a transaction chain uses Practical Byzantine Fault Tolerance consensus to verify the transaction data within those blocks. Thus, building off Bitcoin-NG and ByzCoin protocols, the Cypherium blockchain is optimized for both on-chain scalability & permissionless mineability through this hybrid PBFT/ PoW consensus mechanism. Here’s what it looks like step-by-step:

The leader node (crown) proposes a block, waiting to be verified by validating nodes


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


The new block is then broadcast to all nodes


Honest nodes will reject messages from nodes without PoW


Cypherium hence 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.



Sybil attacks practically impossible


No waiting on transaction confirmation


Highly scalable thousands of transactions per second


No minimum fees for smart contract execution


No fixed block size faster, more adaptable transaction processing as the technology scales

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, like central-bank-issued digital currencies.

Virtual Machine

The Cypherium Virtual Machine revolutionizes smart contract technology. There are four notable innovations we make to the industry standard Ethereum Virtual Machine (EVM) that make this true:

Dalvik Architecture.

Instead of using EVM’s stack-based architecture, we use the register-based, Javascript Dalvik architecture that was created for the Android OS. It is more lightweight and able to run even on mobile devices.

Built-in safety checks.

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

Faster data types.

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

Fixed-point representation.

Fixed-point representation is part of what enable low-cost embedded chip-technology in payment cards, making it a crucial part of modern business transactions. EVM doesn’t have it, but now CVM does.
