Abelian’s Hybrid Proof-of-Work: A New Security Paradigm

In a rapidly evolving blockchain landscape, Abelian distinguishes itself through a forward-looking approach to decentralization, security, and technological resilience. Following the successful Aconcagua Fork, Abelian introduced a Hybrid Proof-of-Work (PoW) model powered by two quantum-resistant mining algorithms: ABEL-ETHash and ABEL-Nakamoto.

‍

At block height 464,000, Abelian completed a major network upgrade that strengthened security, enhanced decentralization, and increased technical versatility, all while establishing a robust foundation for future scalability and innovation. For a deeper technical overview of this milestone and its broader implications, we encourage readers to explore our detailed analysis in – Abelian Completes Major Network Upgrade at Block Height 464,000. 

‍

As the Abelian ecosystem continues to grow, so does the collective contribution of our global community. With that in mind, we believe it is essential to provide clarity around our hybrid PoW design, the role of each mining algorithm, and our long-term commitment to decentralization.

‍

Furthermore, we invite hardware engineers and enthusiasts interested in building their own mining machines to explore the complete source code and detailed information about the ABEL-Nakamoto algorithm, available here: ABEL-Nakamoto Source Code.

‍

This Q&A aims to unpack these topics in greater depth, explaining not only how the system works, but why these design choices matter for the future of quantum-resistant blockchain infrastructure.

‍

Q1: What is the current state of the Abelian network following the Aconcagua Fork?

The Abelian network now operates with two quantum-resistant Proof-of-Work (PoW) mining algorithms: ABEL-ETHash and ABEL-Nakamoto. The consensus protocol dynamically balances the two algorithms, with approximately half of all blocks mined using ABEL-ETHash and the other half using ABEL-Nakamoto.

‍

Q2: What are Abelian’s goals regarding decentralization and security?
From day one, Abelian has been committed to maximizing both decentralization and security. Our vision is to build a network that is not only technically resilient, but also community-driven. We seek to empower participants to collectively build, scale, and safeguard the ecosystem, ensuring that governance, validation, and innovation remain widely distributed rather than concentrated in a few hands.

‍

Q3: How are the two algorithms designed for different types of hardware?
ABEL-ETHash is designed to be GPU-friendly. While CPUs can technically participate in mining, GPUs significantly outperform them, often by more than 100x. Due to its architectural design, FPGAs and ASICs are not economically efficient for this algorithm.

ABEL-Nakamoto, by contrast, is purpose-built for FPGA and ASIC mining. It is optimized for high-performance, dedicated hardware, making it the preferred path for large-scale, energy-efficient, and industrial-grade mining operations.

‍

Q4: What is the significance of the FPGA engineering stage?
Abelian has now entered the FPGA engineering phase, marking a critical milestone in our Proof-of-Work roadmap. The ABEL-Nakamoto algorithm has already been publicly released and has been operating in a live network environment, demonstrating its real-world viability.

However, this FPGA stage should be understood as an “engineering hosting phase” rather than the final destination. It serves as a crucial bridge between experimental deployment and full-scale ASIC industrialization.

‍

Q5: Does the FPGA phase represent the end of development?
No — quite the opposite. Historically, across major Proof-of-Work networks, the FPGA phase has consistently functioned as a transitional stage leading toward ASIC adoption. Without a clear progression beyond FPGA, miners would lack long-term visibility into network security, capital investment, and decentralization strategy. For Abelian, the FPGA phase is a strategic stepping stone, not the endpoint.

‍

Q6: Is the FPGA phase meant to be temporary or a long-term solution?
Our FPGA and ASIC research and development efforts focus exclusively on ABEL-Nakamoto mining. By open-sourcing the ABEL-Nakamoto code, we aim to invite and encourage the broader community, including hardware engineers, researchers, and manufacturers, to contribute to the development of next-generation, quantum-resistant mining infrastructure. These hardware initiatives do not apply to the ABEL-ETHash algorithm, which remains GPU-centric.

‍

Q7: Could the ABEL-Nakamoto algorithm change in the future?
ABEL-Nakamoto was successfully deployed during the Aconcagua Fork and represents a quantum-resistant evolution of Bitcoin’s original Proof-of-Work design. Existing Bitcoin mining hardware is not compatible with ABEL-Nakamoto, and there are no plans to change this incompatibility. Any future modification to the ABEL-Nakamoto algorithm would require a formal hard fork, which would only be considered under exceptional technical or security circumstances.

‍

Q8: How does the project team view its role in computing power moving forward?
We remain firmly committed to decentralization. The Abelian team does not seek to control or dominate network computing power — instead, our goal is the opposite. Our mining roadmap is intentionally structured to encourage broad community participation, ensuring that computational power is widely distributed rather than concentrated within the core team. We aim to create an ecosystem where individuals and independent miners can meaningfully contribute to network security while being fairly rewarded in ABEL for their efforts.

‍

Q9: How is the ABEL-ETHash algorithm currently supported by the community?
Today, ABEL-ETHash mining is largely powered by independent community miners. GPU contributors are actively participating from 32 countries worldwide, reflecting the truly global and decentralized nature of the network. This level of distributed participation underscores both the accessibility of ABEL-ETHash and the strength of Abelian’s grassroots mining community.

‍

Looking ahead, Abelian remains steadfast in its mission to build a secure, resilient, and decentralized ecosystem driven by its community. The achievements of the Aconcagua Fork and the implementation of our hybrid Proof-of-Work model mark only the beginning of this journey.

‍

We invite our community to stay engaged — explore our technical resources, follow our research updates, and read our blogs to understand where the network is heading. Your involvement plays a critical role in shaping Abelian’s future. Together, we will continue to strengthen the foundation of ABEL mining and build a sustainable, long-term ecosystem for the quantum-resistant era.
