How to mine
Select "Settings" -> "Options" from the menu bar.
Or use an external miner, such as cpuminer-heavycoin> ./minerd -a heavy -v 32 -o 192.168.0.120:7202 -O username:password
How to vote
Select "Settings" -> "Options" from the menu bar.
Or use the RPC interfacesetvote <vote> - set your block reward vote
getvote - get your current block reward vote
getmaxvote - get the maximum allowed vote for this phase
Or use the -v parameter to the Heavycoin cpuminer

Innovations and contributions
- HEFTY1 - a cryptographic hash function for ASIC-resistant proof-of-work with a small memory footprint
- Ultra-secure hashing - a secure strategy for using multiple cryptographic hash functions
- Temporal Retargeting - multipool protection that goes beyond Kimoto Gravity Well
- Decentralized Block Reward Voting - the mining schedule and money supply are democratically decided (total supply is still bounded to 128M)
Goals
- Achieve massive adoption as a major crypto-currency
- Provide long-term open source development, support and maintenance
- Promote a large-scale decentralized mining community
- Build a gigantic community of stakeholders from a diverse set backgrounds
- Promote the use of democratic processes in peer-to-peer systems using decentralized block reward voting
Specification
- ASIC-resistant: Introduces HEFTY1, a novel approach to ASIC-resistant proof-of-work
- Ultra-secure: combines SHA-256, Keccak-512, Grøestl-512, BLAKE-512 in a secure way
- Block time: 2 Min
- Retarget up: Every 5 blocks (max 100%)
- Retarget down: Every block (max 400%)
- Starting block reward: 0 (for first 100 blocks ~ 3.3 hours)
- Block reward: 1024 max (decentralized block reward voting)
- Total supply: 63M to 128M HVC (depending on decentralized block reward voting)
- Multipool protection:
Kimoto Gravity Well Temporal Retargeting - Premine: 1-2% (depending on total supply) for future development, support and maintenance
- Bounties: 1-2% (depending on total supply) for strategic direction and promoting of heavycoin
Core team
Heavycoin has a strong developer backing who are comitted to its success. Over time we hope the Heavycoin developer community will grow larger and our long-term goal is to form an open source Heavycoin Foundation for promoting and developing Heavycoin over many years to come.

Decentalized Block Reward Voting
Heavycoin introduces a new dynamic with decentralized block reward voting. Heavycoin is the first crypto-currency where the mining schedule and money supply are decided democratically by its user-base. This is achieved by allowing miners to participate in a fully decentralized cheat-proof voting process. The money supply still has a fixed upper-bound of 128M HVC.
Intially Heavycoin starts with a zero block reward. The very first miners will have the first opportunity to solve blocks and vote on what the first democratically selected block reward should be. The first 100 blocks (3.3 hours) will decide the starting block reward. From then on, block reward voting will continue, but the votes are counted and averaged every 3600 blocks (5 days).
How to voteHeavycoin is configured to mine and vote by default, with a default vote of 512 HVC. If you want to change your block reward vote then see the
"How to vote" and
"RPC voting" sections of our website (alternatively some information is provided below). When mining is enabled, every time you mine a block your wallet will automatically cast a block reward vote. The Heavycoin network automatically averages these votes every 5 days (3600 blocks) and sets the new block reward accordingly. The block reward is the average of all 3600 votes over the previous voting period rounded to the nearest integer.
Voting RPC interface:setvote <vote> - set your block reward vote
getvote - get your current block reward vote
getmaxvote - get the maximum allowed vote for this phase
getphase - get the current voting phase name (eg. "Mint", "Limit" or "Sustain")
getsupply - get the current money supply
getreward - get the current block reward
getmaxmoney - get the maximum possible money supply
