How to Use BetterHash for One-Click Mining? (Easy Start)

Understanding BetterHash Architecture

1. BetterHash separates the mining protocol logic from the block template construction, allowing miners to validate and modify block templates before submitting shares.

2. The protocol replaces the legacy stratum v1 handshake with a more flexible negotiation layer that supports dynamic job distribution and client-side coinbase control.

3. It introduces a standardized JSON-RPC interface for job delivery, eliminating hardcoded extranonce2 sizes and rigid difficulty adjustments.

4. Mining pools implementing BetterHash expose extended capabilities via the 'mining.configure' method during connection setup, signaling support for custom coinbase transactions.

5. Unlike traditional stratum, BetterHash does not require the pool to construct the entire block header — instead, it delegates partial responsibility to the miner’s software.

Setting Up Your Miner for One-Click Launch

1. Download a BetterHash-compatible miner such as BFGMiner 5.5.0+ or CGMiner 4.10.0+, both of which include native stratum v2/BetterHash extensions.

2. Install the miner binary and verify compatibility by running --version and checking for “stratum2” or “betterhash” in the feature list.

3. Configure your miner.conf file with pool URL using the stratum2+tcp:// prefix instead of stratum+tcp:// to enforce BetterHash mode.

4. Assign a wallet address directly in the configuration using the --coinbase-addr flag — this bypasses pool-side coinbase insertion and ensures on-chain attribution.

5. Launch the binary without additional CLI arguments if auto-detection is enabled; the miner will negotiate BetterHash parameters during initial handshake.

Verifying Protocol Handshake Success

1. Monitor console output for messages containing 'mining.configure', 'mining.set_version_bits', or 'mining.set_extranonce' — these indicate active BetterHash negotiation.

2. Check for absence of deprecated stratum v1 commands like 'mining.notify' with fixed extranonce1/2 fields — their omission confirms protocol upgrade.

3. Observe whether submitted shares include a full coinbase transaction hex rather than just a merkle branch — this is a definitive signature of BetterHash operation.

4. Use Wireshark with stratum2 filters to capture raw packets and confirm the presence of 'job_id', 'target', and 'coinbase_tx' keys in job objects.

Troubleshooting Common Connection Failures

1. If the miner falls back to stratum v1, verify that the pool supports BetterHash by consulting its documentation or testing against known endpoints like stratum2+tcp://btc.ss.pool:3333.

2. Authentication errors often stem from missing or malformed 'mining.authorize' payloads — ensure username includes worker ID suffix (e.g., “wallet.worker1”) and password is empty or “x”.

3. Stale job submissions may occur when system clock drift exceeds 30 seconds; synchronize time using ntpd or chrony before launching.

4. GPU miners sometimes fail to parse large coinbase transactions due to buffer limits — increase --max-buffer-size to 1048576 bytes if encountering truncated TX errors.

Frequently Asked Questions

Q: Does BetterHash require changes to my wallet software?A: No. Wallets remain unaffected. BetterHash operates at the mining protocol layer and only influences how coinbase outputs are constructed before block submission.

Q: Can I use BetterHash with merged mining setups?A: Yes. Merged mining configurations remain valid as long as the auxiliary chain’s stratum implementation supports the same negotiation extensions and job serialization format.

Q: Is there any difference in hashrate reporting between BetterHash and legacy stratum?A: Hashrate calculation remains identical. Share submission frequency and difficulty targets are preserved; only the content and structure of job objects change.

Q: Do I need to reconfigure my firewall for BetterHash?A: No. BetterHash uses the same TCP ports as standard stratum. No new inbound or outbound port rules are required beyond existing mining infrastructure allowances.
