Mine CYNC from your PC
CoinCync uses RandomX — a CPU-only proof-of-work designed so that anyone with a regular computer can secure the network. No GPUs, no ASICs, no warehouse. The chain is more decentralized when more home machines mine; that’s the whole point of the algorithm.
You will need
- Any modern computer (Windows, Linux, or macOS)
- A CoinCync wallet address starting with
tCYNC...to receive rewards (create a wallet if you don’t have one) - A few minutes
You do not need a GPU, special hardware, or any kind of exchange account.
Quick start
All testnet binaries are published as a single GitHub release at
v1.0.2-testnet
along with SHA256SUMS.txt. Verify after download with
sha256sum -c SHA256SUMS.txt.
Windows
Download the node binary:
Open PowerShell in the folder where you saved them and run:
# Start a node (leave this window running)
.\coincync-node.exe --network testnet
# In a second window, start mining (replace tCYNC… with your address)
.\coincync-rig.exe run-solo --node http://127.0.0.1:28081 `
--address tCYNC3Z6jt428m... --threads 4 --tui
The --tui flag opens a live ratatui dashboard (stats bar +
scrolling log). Press q or Esc to quit.

macOS
The macOS-native build is not yet published; build from source for
Apple Silicon (see Build from source). Reproducible
build environment is documented in
docs/operations/REPRODUCIBLE_BUILDS.md.
What success looks like
The miner prints scrolling tracing-style output:
2026-05-02T19:00:01Z INFO miner: ✓ BLOCK FOUND at height 753!
2026-05-02T19:00:03Z INFO chain h=753 tip_age=2s diff=302 peers=8 synced=true
2026-05-02T19:00:18Z INFO miner: ✓ BLOCK FOUND at height 754!
Each BLOCK FOUND line means your machine just produced a block. The
mining reward (currently ~50 CYNC per block) goes to the address
you passed in --address.
Where NOT to run a miner
Most cloud and dedicated-server providers prohibit mining, including DigitalOcean, AWS, GCP, Azure, Cloudflare, Hetzner, OVH, and Vultr. Trying to mine on those services will get your account suspended.
The right places to run a CoinCync miner are:
- Your home computer
- A spare machine you own (mini-PC, Pi 5, old laptop)
- A box you’ve put in colocation (you own the hardware, the provider only rents space and bandwidth)
This is fine — RandomX is designed to run efficiently on the kind of CPU you already have. A modest desktop will mine just as well as a purpose-built rig.
How much will I earn?
Testnet CYNC has no monetary value. Treat mining rewards as a way to verify your wallet works, send transactions, and stress-test the network. Mainnet launch is targeted for October 2026; testnet mining is preparation, not income.
Stopping the miner
Press Ctrl+C in the miner window. The node keeps running until you
stop it the same way. Restart either at any time — your chain state
and wallet are saved on disk and pick up where they left off.
What if I’m the only miner?
If everyone running CoinCync stops mining, the chain stops producing blocks. The chain doesn’t break — it just sits at the current tip until someone resumes. This makes mining inherently a community activity. The more home miners, the more resilient the network. That’s exactly the architecture we want.
