About the Team

XRPHD Team

XRPHD is the team behind XHD, a hard drive mining cryptocurrency built on Conditioned Proof of Capacity (CPOC). Our network includes the blockchain protocol, the full node wallet, and the mining software. XHD trades under the ticker XHD.

About XHD Project and Network

XHD rewards miners based on committed hard drive capacity. Miners plot data to local drives and compete for block rewards through CPOC consensus. No GPU or ASIC hardware is required.

Marcus Vance

Founder & Project Lead

Marcus brings over 12 years in crypto and decentralized finance to the table. As the co-founder of the network, his primary area of responsibility is the strategic roadmap and core protocol architecture. His most concrete contribution to the project was designing the specific Shabal256 adaptations for our CPOC mechanism.

David Chen

Lead Developer

David is a senior software engineer with a deep background in C++ and cryptography. Leading the XHD developers team, his specific focus area is network consensus and node security. In 2021, he successfully authored and executed the major protocol update that prevented 51% attacks on low-capacity plots.

Elena Rostova

Wallet & Mining Engineer

Elena’s engineering background lies in database management and local hardware optimization. She is responsible for wallet sync speeds, plot file access, and overall miner performance. Her standout technical contribution was rewriting the disk-read algorithm in 2023, which reduced plotting time by 30% for high-capacity HDDs.

Julian Hayes

Technical Writer

With a strong editorial background in Web3, Julian manages our strict editorial policy and project documentation. He is responsible for translating complex CPOC concepts into accessible user guides and release notes. This ensures our mission of open-source transparency is met with every software update.

SJ

Sarah Jenkins

Community & Support

Sarah has extensive experience managing tech communities. She handles direct support for miners and wallet users facing sync or plotting issues. She runs our social channels, coordinates community feedback, and bridges the gap between users and the dev team.

Development

Our team maintains the full node wallet, the CPOC consensus layer, and the mining software across Windows, macOS, and Linux. Currently, we are focused on wallet sync speed, address handling, and plot file read performance.

XHD uses the Shabal256 algorithm for plot file generation. Plotting runs on local hard drives. During mining, the software reads plotted data from disk and submits deadline calculations to the network for each block round.

Project History

October 23, 2019

BitMart opened the XHD token sale. The sale asset was priced against BHD with a hard cap of 500,000 USDT. BitMart confirmed the 90,000,000,000 XHD total supply at launch.

October 24, 2019

The XHD/BHD trading pair went live on BitMart.

March 15, 2021

The team released the v.2.0 Full Node Wallet, drastically reducing initial blockchain sync times for new miners.

August 10, 2023

Deployment of the advanced Plotting Software GUI, making HDD mining accessible to non-technical users.

January 12, 2026

Expanded our community outreach, releasing updated technical documentation to support cross-border decentralized payments.

XRPHD is Open Source

We believe in total transparency. Wallet binaries, technical documentation, and our full release history have always been public. Currently, our core development team is migrating our repositories from centralized platforms to a decentralized, self-hosted Git environment to ensure absolute censorship resistance. During this infrastructure upgrade, release packages, changelogs, and source code archives are available upon request via our support email.
