CypherBFT: The road to Web3 and AI integration

4 min readJun 9, 2024


Proof-of-Work (PoW), best known for its application in Bitcoin and other cryptocurrencies, is a consensus mechanism that involves solving complex mathematical problems, which require substantial computational resources. This process secures blockchain networks against attacks by making it economically unfeasible to gain control without significant investment in hardware and energy. Critics argue that PoW is inefficient and environmentally harmful due to its high energy consumption, leading to negative portrayals in the media and even outright bans in some countries.

However, PoW has also spurred technological advancements, particularly in the graphics card industry, essential for both cryptocurrency mining and AI development. For instance, companies like Nvidia have thrived by supplying the hardware needed for both sectors, indicating a convergence between PoW mining and AI technologies.

The key to integrating AI and Web3 using PoW lies in evolving the use of computational power from mere hash calculations to more productive applications like AI training. This evolution, from what we might call PoW 1.0 to PoW 2.0, suggests a transition towards utilizing the extensive PoW infrastructure for advancing AI technologies. This could mean redesigning PoW tasks to directly support AI processes, thereby not only maintaining network security but also contributing to AI research and development. This integration could leverage the distributed nature of blockchain technologies to decentralize AI computations, potentially leading to innovations in how AI is trained and implemented across various industries.

Classic PoW, a concept pioneered by Satoshi Nakamoto, entails repeatedly computing hash functions like SHA256 to find values that satisfy predefined criteria, a process known as mining difficulty. This mechanism, while energy-intensive — Bitcoin mining consumes five times the power of systems running AI models like ChatGPT — serves a critical function in securing blockchain networks. The high difficulty in generating a valid hash ensures security since these hashes are straightforward to verify but computationally expensive to produce.

Despite the considerable energy expenditure, traditional PoW has not been leveraged for purposes beyond maintaining blockchain integrity, leading to perceptions of wasted resources. However, the cryptographic hashing involved is crucial for network security.

Addressing this issue, Cypherium innovatively introduces dual-purpose use of the computational resources involved in PoW — an alternating system where nodes conduct hash mining and AI processing. This model leverages GPUs, which are less specialized than the ASICs used in Bitcoin mining, allowing the same hardware to be utilized for AI training. This approach not only enhances the efficiency of the resource use but also broadens the applicative landscape of PoW, merging blockchain security functions with productive AI computational tasks.

In Cypherium’s consensus mechanism, CypherBFT, a node can fulfill one of three distinct roles: a validator, which has the authority to approve transactions; a candidate, actively engaged in the mining process; and a non-validator, which primarily relays blockchain data. The computational effort needed for validating transactions is significantly less than what is required for executing the PoW tasks. Consequently, when a candidate node ascends to the role of a validator, much of its computational capacity becomes available for other purposes.

Leveraging this excess capacity, Cypherium employs virtualization technology to aggregate the computational resources of all its validator nodes. This collective power is then utilized as a virtual data center, dedicated to AI training. This innovative approach not only optimizes the use of computational resources within the blockchain network but also extends the utility of these resources beyond traditional blockchain tasks. By doing so, Cypherium effectively transforms the network’s distributed computational power into a valuable asset for more complex and resource-intensive applications such as AI, enhancing the overall efficiency and functionality of the blockchain system.

The lifecycle of a node in the Cypherium network proceeds as follows:

  1. Mining Initiation: A node, or mining rig, begins by engaging in the mining process.
  2. Becoming a Validator: Upon successfully completing a valid PoW, the node transitions into a validator role.
  3. Dual Functionality as Validator: As a validator, the node undertakes transaction processing alongside AI training. Both activities generate rewards in Cypherium’s native token, CPH. Additionally, users can rent the validator’s computational power using CPH, further leveraging the node’s capabilities.
  4. Term Completion and Transition: After serving its term as a validator, the node reverts to the mining stage, thereby repeating the cycle.

To ensure continuity and efficiency, the state of the AI computations is preserved within a virtual machine. This allows the AI processes to continue uninterrupted, even as the validator’s role is cycled out and its computational responsibilities are assumed by incoming validators. This system not only maximizes the use of computational resources across the network but also ensures seamless operational transitions, enhancing both the blockchain functionality and the AI training processes.

By integrating CypherBFT’s permissionless consensus mechanism with advanced cloud computing technologies, Cypherium has pioneered the use of PoW power for AI training without compromising blockchain security. This groundbreaking approach marks a significant milestone in blockchain and AI integration, ensuring robust network safety while redirecting computational resources previously deemed excessive towards productive AI development.

At the core of our vision is the belief that AI technology should be universally accessible, not confined within the walls of tech conglomerates. By democratizing AI computational power through PoW, we aim to level the playing field, enabling wider access to these transformative technologies.

Looking ahead, we aspire to evolve hash mining into a process primarily focused on AI training, thereby aligning blockchain incentives with broader technological advancement.
