HashmonkeyCoin is a Monero-based privacy coin fork with HMNY branding, custom network parameters, and a community-first roadmap. This repository is not affiliated with the Monero Project.

- Mainnet is prepared but not launched: no public seeds; mining requires
--allow-mainnet-mining. - Testnet is for public testing. Public seed:
seednode.hashmonkeys.cloud(P2P 48080, RPC 48081). See TESTNET-GUIDE.md.

Fork notice: HashmonkeyCoin is based on the Monero Project. Upstream copyright and license terms in source files are retained.
Build order: hashmonkey-core first, then hashmonkey-gui. Most users should use GitHub Releases instead of compiling. See TESTNET-GUIDE.md for download, testnet, and build instructions.
HMNY uses the same Monero-style emission curve as the upstream core (smooth reward decay + permanent tail emission). There is no founder premine, no ICO allocation, and no hidden genesis payout—only standard block rewards paid to miners (and fees).
| Topic | HMNY (mainnet parameters) |
|---|---|
| Premine / dev allocation | None — genesis block follows the normal Cryptonote genesis layout; coins enter circulation only via block rewards |
| Smallest unit | 1 atomic unit = 10⁻¹² HMNY (COIN = 10¹² atomic units per 1 HMNY) |
| Display decimals | 12 |
| Block time (v2+) | ~2 minutes (DIFFICULTY_TARGET_V2 = 120s) |
| Proof-of-work | RandomX (CPU-oriented, Monero-compatible) |
| First minable block reward | ~35.18 HMNY (height 1+, empty already_generated_coins) |
| Tail emission (per block) | 0.6 HMNY per block (~0.3 HMNY/minute) |
| Main emission phase | Smooth curve until tail; ~18.1M HMNY mined before the reward floor (~2.13M blocks at 2 min/block) |
| Hard cap in code | MONEY_SUPPLY uses the Monero formula constant (UINT64_MAX in cryptonote_config.h)—rewards taper via the emission function, not a Bitcoin-style halving schedule |
| Fees | Transaction fees go to the miner of the block (same as Monero) |
- Genesis (height 0) — establishes the chain; no large pre-allocated community/treasury balance in protocol config.
- Mining rewards — each block pays
get_block_reward()fromcryptonote_basic_impl.cpp(smooth decay, then tail). - Tail phase — after the main curve, every block pays at least 0.6 HMNY forever (incentivizes long-term miners and network security).
- Treasury / community fund (future) — not embedded in the current chain rules; any Phase 2 treasury would need a transparent, community-approved mechanism (see roadmap), separate from a silent premine.
Testnet HMNY has no monetary value and uses separate network IDs, ports, and genesis nonce. Consensus rules mirror mainnet (same hardfork heights in hashmonkey-core/src/hardforks/hardforks.cpp; RandomX from block 12). Testnet is for development, wallet testing, and public trials only. Mainnet is not launched yet (--allow-mainnet-mining is required until public launch).
Hardforks: HMNY does not follow Monero’s historical fork calendar. See TESTNET-GUIDE.md — Hardfork schedule (HMNY) and hashmonkey-core/README-HMNY.md. After a consensus schedule change in a new release, wipe local testnet chain data (~/.hashmonkeycoin/testnet on Linux, %ProgramData%\hashmonkeycoin\testnet on Windows) and sync again from seednode.hashmonkeys.cloud.
Emission constants: hashmonkey-core/src/cryptonote_config.h (EMISSION_SPEED_FACTOR_PER_MINUTE, FINAL_SUBSIDY_PER_MINUTE, DIFFICULTY_TARGET_V2, COIN). Reward logic: hashmonkey-core/src/cryptonote_basic/cryptonote_basic_impl.cpp → get_block_reward().
Prebuilt binaries: v0.2.5-testnet (Windows zip + Linux tarball + SHA256SUMS.txt) · all releases.
New users: TESTNET-GUIDE.md (download, wallet wizard, pool mining, troubleshooting).
Developers: same guide — Build from source and hashmonkey-core/README-HMNY.md / hashmonkey-gui/README-HMNY.md.
- Renamed binaries:
hashmonkeyd,hashmonkey-wallet-cli,hashmonkey-wallet-gui - Custom
NETWORK_ID, ports, and address prefixes - GUI defaults to testnet; mainnet mining gated behind
--allow-mainnet-mining - Wallet restore height
0on fresh HMNY chains (no Monero block-height estimator) - Solo mining works without waiting for a peer on genesis chains
- HashmonkeyCoin branding; Monero update checks disabled in
hashmonkeyd

Goals: Fork and customize the HMNY blockchain core; configure RandomX; build seed nodes and bootstrap infrastructure; launch community channels; begin public testnet mining.
Deliverables: HMNY daemon, CLI wallet, public GitHub repository, seed nodes, testnet explorer, faucet, initial documentation, community Discord/Telegram, website integration with HashMonkeys.cloud.
Technical focus: RandomX optimization, network stability, fair launch preparation, difficulty tuning, anti-spam and peer protections, lightweight syncing research.
Community: Public testnet participation, miner onboarding, bug testing, transparent updates, early node operator incentives.
Goals: Public HMNY mainnet launch; community-first mining; decentralized node infrastructure; sustainable treasury.
Launch principles: No ICO, no VC allocation, no hidden premine, transparent treasury, public mining from launch.
Deliverables: Mainnet release, GUI desktop wallet, Linux/Windows miners, community pools, network monitoring, explorer redundancy, bootstrap tools.
Treasury (transparent, community-reported) may fund global node expansion, server scaling, redundancy, DDoS mitigation, bandwidth, backups, monitoring, and ecosystem tools.
Community incentives: Early miner rewards, node operator recognition, events, mining competitions, governance preparation.
Vision: Passive, intelligent mining for everyday users and gamers—idle hardware contributes without disrupting normal PC use.
Deliverables: One-click mining launcher; idle mining mode (pause during gaming/streaming/heavy load); smart auto-throttle (CPU temp, load, apps); CPU/GPU resource management; mobile wallet and miner monitoring.
Vision: Evolve beyond traditional mining into decentralized compute powered by community hardware.
Exploration: AI inference, distributed rendering, edge compute, game server hosting, community cloud, distributed storage, compute marketplace.
Deliverables: Compute contribution framework, node reputation, reliability scoring, resource allocation, developer APIs.
Goals: Long-term sustainability, transparent governance, community-driven funding.
Deliverables: Governance portal, treasury dashboard, proposals, voting, public infrastructure reporting, ecosystem grants.
Long-term objective: A decentralized mining ecosystem, gamer-friendly idle compute network, community-owned infrastructure, and a scalable platform for distributed participation.
