Haven (HVN)
Global Internet Money · CPU-only fair launch
Haven mainnet

Global Internet Money, mined by laptops.

Haven is a clean experiment in decentralised money. No premine, no special addresses, no VC allocation, and no dev fee. Anyone with a CPU can mine from block 1 under the same rules.

CPU-only PoW RandomX (Monero-style) No founders’ allocation No marketing wallet

This page takes its data directly from the live seed node via /api/hvn/status and /api/hvn/block/latest. Don’t trust, verify.

Fair-launch rules

Haven is designed to be boring, verifiable money. The rules are simple and enforced by code, not marketing slides:
  • No premine: circulating supply at launch is exactly 0 HVN.
  • No special addresses: there is no founders’, team or VC wallet baked into consensus.
  • No dev fee: miners keep 100% of the block reward.
  • No VC allocation or ICO: no token sale, no private round, and no discount deals.
  • No marketing wallet: any promotion is grassroots, not pre-funded from supply.

Technical spec

Ticker HVN
Total supply 21,000,000,000 HVN (hard cap)
Consensus Proof-of-Work, RandomX
Security model “One CPU, one vote” – ASIC & GPU-resistant
Target block time 10 seconds
Difficulty Retarget every block
Genesis Block 0 subsidy is provably unspendable; supply begins at block 1
Block reward 7,200 HVN at block 1, smooth emission
Implementation Full node & wallet in Rust, open-source

Create a wallet (non-custodial)

Haven wallets are non-custodial. You generate your seed locally and you are the only one who controls your keys.
  1. Download the wallet CLI (link will appear here once the first public binaries are published).
  2. Run the wallet on a trusted machine and generate a new wallet with a 24-word seed phrase.
  3. Write the seed on paper and store it safely offline. Anyone with the seed can spend your HVN.
  4. Use your HVN address (it will start with hvn1…) to receive mined coins or transfers.

Tip: you can later create a “view-only” wallet for everyday use and keep your spending keys offline.

Start mining Haven

Haven is CPU-only. If you have a laptop or spare desktop, you have hashpower.
  1. Sync a full node.
    Once binaries are public, you’ll be able to run something like:
    havend --peer hvngim.org:4000
  2. Enable mining on your node (integrated miner) or point a RandomX CPU miner to a community pool.
  3. Watch block rewards flow to your HVN address as your CPU finds valid blocks.

Community pools and a one-click CPU miner will be announced on X and Discord once they’re live.

Verify the launch

“Don’t trust, verify” is the whole point. You don’t need to believe any website or founder, including this one.
  • Audit the source: verify the code on GitHub once it is public.
  • Check block 0: query it via /api/hvn/block/latest or block-explorer tools to confirm its subsidy is unspendable.
  • Scan the chain: check there are no special founder, team or dev-fee outputs.
  • Verify emission: sum block rewards and confirm they converge to the advertised hard cap.

If you can run a node and a block explorer, you can prove Haven launched with zero spendable supply and no hidden allocations.

Downloads

Official binaries are published here. Always verify checksums before running.

Chain bootstrap

Miner (Linux x86_64)

sudo mkdir -p /opt/haven /var/lib/haven
sudo curl -fsSL https://hvngim.org/files/havend-linux-amd64 -o /opt/haven/havend
sudo chmod +x /opt/haven/havend
curl -fsSL https://hvngim.org/files/havend-linux-amd64.sha256
sha256sum /opt/haven/havend

Note: RandomX mining may not work under WSL2. For mining, use a real Linux host.

Node & Wallet bundles

Older builds remain available for compatibility, but the latest release is recommended.

Official HVN Node (havend) – Linux x86_64

Install (copy/paste) 
sudo mkdir -p /opt/haven
sudo curl -fsSL https://hvngim.org/files/havend-linux-amd64 -o /opt/haven/havend
sudo chmod +x /opt/haven/havend
curl -fsSL https://hvngim.org/files/havend-linux-amd64.sha256
sha256sum /opt/haven/havend
/opt/haven/havend --help | head
Note: WSL2 may crash RandomX with “Illegal instruction”. For mining, use a real Linux host (bare metal or full VM).

Node & CLI wallet (Linux x86_64)

✅ Latest (recommended)

hvn-node-linux-x64-v0.1.1.tar.gz
Includes updated havend, CLI tools, and correct RandomX settings.

SHA256: hvn-node-linux-x64-v0.1.1.tar.gz.sha256

Legacy (previous release)

hvn-node-linux-x64-v0.1.0.tar.gz
Older release kept for compatibility.
Contains hvn-node and CLI wallet tools.

CPU Miner – One-click (Linux x86_64)

hvn-oneclick-miner-linux-x64-v0.1.0.tar.gz
Unpack → run ./mine-haven.sh → paste your hvn1... address → mining starts.

Node + Wallet (Windows x86_64)

hvn-node-windows-x64-v0.1.0.zip
Extract → run hvn-node.exe --help.


Create a wallet

  1. Download the **Node/CLI** for your OS.
  2. Run on a trusted machine:
./hvn-node info --new-wallet
(coming soon – CLI wallet commands are being added)
  1. Wallet CLI (Linux x86_64)
    hvn-wallet-linux-x64-v0.1.0.tar.gz
    Non-custodial CLI wallet. Unpack, run ./hvn-wallet, and follow the prompts to create your hvn1... address.


Run a full node

./hvn-node \
  --data-dir ./data \
  --rpc-bind 0.0.0.0:5001 \
  --p2p-bind 0.0.0.0:4000 \
  --peer seed.hvngim.org:4000 \
  --coinbase-address hvn1YOURADDRESS
⚠️ Never run without --coinbase-address or rewards go to the default dev address.


Start mining

  1. Sync your node against the seed:
./hvn-node --peer seed.hvngim.org:4000 --coinbase-address hvn1YOU
  1. CPU mining begins automatically (1 CPU = 1 vote).
  2. Rewards go to hvn1YOURADDRESS.

One-click miner (recommended)

tar -xf hvn-oneclick-miner-linux-x64-v0.1.0.tar.gz
cd hvn-oneclick-miner-linux-x64-v0.1.0/
./mine-haven.sh
Works on any laptop/desktop CPU. No premine, no special addresses, no dev tax.
