About HDD.Cash (HDD)

HDD.Cash is a new cryptocurrency based on the CPoC (Conditioned Proof of Capacity) and zk-SNARK protocol. HDD.Cash inherits the decentralized values of existing cryptocurrencies while providing an extra layer of privacy.

• Total Supply: 1,000,000,000 HDD

Features：

1. By adopting a storage-based consensus algorithm, miners no longer need to invest in the power-hungry and expensive equipment. CPOC allows everyone to mine through their hard disks at home. The optimized measures for hard disks allow a much lower retrieval cost. Compared to PoW algorithm, a capacity-based consensus is more cost-efficient and environmentally friendly. For miners, hard disk mining is cheaper and quieter.
2. PoC mitigates the advantage of ASIC devices, which resolves the core centralization problems faced by the current mainstream consensus. The ability to withstand ASIC allows ordinary storage devices (e.g., personal PC's hard disks) to participate equally in the network, obtain corresponding benefits, and reduce the threshold for the ordinary participants, which is in line with the ideology behind decentralization. CPoC has solved the problem of incentive mechanism in the traditional PoC. Miners who participated in the later stage can still obtain considerable benefits, which can ensure the sustainable development of the system.
3. Compared with the existing CPoC coins, HDD.Cash has added the zk- SNARK protocol, which can support private transactions while preserving the existing transaction model. Users can choose to initiate private transactions in order to ensure the validity of the transaction through zero-knowledge proof, under the circumstance of not exposing any private information of the transaction (including sender‘s address, receiver’s address, amount, etc.). By providing privacy, HDD.Cash is poised to support more application scenarios.

Thank you all for your support!
