What is HDDcoin?

HDDcoin is an eco-friendly decentralization blockchain based on the Proof of Space and Time (PoST) consensus. It maintains network robustness, in line with Satoshi Nakamoto’s principles.

Miners and Mining in Bitcoin terms is synonymous with Farmers and Farming in HDDcoin terms.

Farming HDDcoin does not consume significant amounts of electricity, and utilizes hard drive space, instead of specialized computing hardware that most Proof of Work (PoW) consensus blockchains have come to demand. Moreover, since electrical energy costs for running hard drives is very minimal, due to this low cost of entry, HDDcoin will remain more decentralized and fair, and thus more secure than any Proof of Stake cryptocurrency.

HDDcoin uses the powerful and secure Chialisp language for Smart Contracts, and supports digital money, global payments and applications.

HDDcoin core values include green cryptocurrency, long term value, building for the future, strength in community, and maintaining a huge team to ensure long term development.

The goal of HDDcoin is to reshape the global financial system through the power of the blockchain technology, powered by thousands of nodes maintained by the community, and with transparency and a commitment to the environment — thereby taking control from any central entity, person or organization, and giving that control back to the community.

What is Co-farming plots?

HDDcoin uses the same plot format as Chia™ who pioneered the Proof of Space Time consensus, allowing you to farm plots created for Chia™ or other blockchains using the same plot format for the HDDcoin blockchain.

Plots are storage space allocated on your Hard Disk Drives for farming.

Sharing the same plots to secure multiple Proof of Space Time blockchains is called co-farming and is another way that HDDcoin is eco-friendly, there is no need to generate plots for HDDcoin specifically, your existing Chia™ work right out of the box.

Why pre-farm HDD?

3.5 Million HDD coins were minted at the very start of the blockchain and put in the developers wallet. Their use is to support the blockchain’s success, development and survival.

HDD coins from the wallet will be used to cover various costs to maintain the blockchain including the following:

  • The HDDcoin blockchain requires special powerful computers called Timelords.
  • Marketing to attract and maintain participation in the blockchain.
  • Exchange listings & liquidity pools (Decentralized Finance).
  • Developer grants to build out Smart Contracts, and tools for the blockchain.
