Your first steps with Scash

Watch the Linux illustration

This recording uses Scash 2.0.0 on an isolated Linux test chain with no funds or internet peers. It illustrates wallet creation, the synchronization screen and an offline CPU miner test. It does not show a mainnet sync completing or a mining payout. The same sequence helps explain Windows and Mac setup; menus and available packages differ.

1. Choose software for your computer

The node contains the wallet; cpuminer-scash is a separate program. These archived releases are the reference versions used in this guide: Scash 2.0.0 / Core 27.0.0 and cpuminer-scash 3.0.9, checked 22 September 2026. Check maintenance status and release notes before installing.

Node release and checksums · Miner release and checksums

Compare the downloaded file’s SHA-256 digest with the publisher’s release notes or SHA256SUMS. Replace FILE with the actual filename; a matching digest confirms file consistency, not software safety.

Linux:       sha256sum FILE
macOS:       shasum -a 256 FILE
PowerShell:  Get-FileHash .\FILE -Algorithm SHA256

2. Create and back up a wallet

1. Open the Scash graphical node and use its normal mainnet settings. The video’s regression-test mode is only for demonstration; do not use its test addresses for real funds.
2. Choose File → Create Wallet, name it and enable encryption. Keep the passphrase offline. If recording your own guide, pause capture while entering private material.
3. Use File → Backup Wallet and save a copy to offline storage. Test restoration from a copy before funding the wallet.
4. Open Receive and create a dedicated mining address. Keep the entire address intact when copying it to your miner or pool settings.

3. Check synchronization before solo mining

Leave the node running while it downloads and verifies the chain. Sync time depends on storage, CPU, connection and peers; the short video does not represent the wait. Check the synchronization indicator and peer connections. In Window → Console, run:

getblockchaininfo
getconnectioncount

For mainnet, confirm chain is main, initialblockdownload is false, blocks has caught up with headers, and the latest block is reasonably current against an independent explorer. A peer count of zero or an old tip needs investigation. The disconnected test chain shown in the video is not ready for mainnet mining.

4. Start small, then confirm accepted work

First try the miner’s offline benchmark. It needs no wallet credentials or pool and earns no rewards. These examples use two threads and 5,000 hashes per thread; stop with Ctrl+C if the system becomes too hot or unresponsive.

# Linux / compatible macOS miner
./minerd --benchmark --nonces=5000 -t 2

# Windows PowerShell
.\minerd.exe --benchmark --nonces=5000 -t 2

For pool mining, choose a SCASH-compatible pool, review its fees and minimum payout, and copy its current endpoint, TLS requirements and wallet/worker format. Replace every placeholder below with that pool’s documented values. A local node is not required to request pool work, although your wallet node needs to sync to show current balances.

./minerd --url=stratum+tcps://POOL_HOST:PORT --user=WALLET_WORKER --pass=POOL_PASSWORD -t 2

On Windows replace ./minerd with .\minerd.exe. Use the pool’s documented protocol; do not disable certificate verification to bypass a connection error. Confirm accepted shares in both the miner and pool dashboard. A hashrate alone does not prove the pool accepted your work.

In cpuminer-scash 3.0.9, use --nonces=5000 with an equals sign. The spaced form --nonces 5000 crashed in our Linux test before mining started; the equals-sign form ran successfully.

5. Measure electricity use

Use a wall meter for the whole computer. Record five minutes at idle, then average a stable mining interval of at least ten minutes after warm-up. Keep screen, peripherals and background work consistent. CPU package sensors do not measure whole-system electricity. Without a wall meter, report power as not measured.

Example only: 120 W × 8 hours ÷ 1,000 = 0.96 kWh. At €0.30/kWh, that is €0.288. This is arithmetic, not a measured Scash result or a profit estimate.

If something does not work

No peers / sync stays still

Check your internet connection, clock, firewall and software’s network selection. Ask the community for currently maintained node guidance; avoid copying unknown peer addresses from direct messages.

Program will not start

Confirm operating system, architecture and checksum. Read the exact error. Do not globally disable antivirus or operating-system protection to run a download.

Rejected shares / authentication error

Recheck the pool’s current endpoint and login format. Solo-node RPC credentials and pool credentials serve different purposes.

Hot or sluggish computer

Stop mining, check cooling and reduce threads before trying again. Stay within the CPU manufacturer’s temperature and power limits.
