Swing (SWING) Mining Pool Setup — SHA256/SHA256d Operator Runbook
Because Swing is mined with SHA256/SHA256d, it fits naturally into ASIC‑based pool operations. This guide walks through the practical pieces we deploy for a reliable SWING mining pool: node/RPC, Stratum behavior, payouts, and public documentation.
SWING pool prerequisites: confirm chain rules before you publish endpoints
Before you accept real miners, prove that the SWING daemon behaves predictably: consistent headers, stable mempool policy, and RPC calls that don’t change semantics across restarts. Pool outages often start as “the node looked fine” problems.
- Consensus confirmation: verify the chain’s proof-of-work settings and any edge cases (difficulty adjustment, checkpoints, or unusual scripts) using daemon docs and source references.
- RPC posture: keep wallet RPC private, log sensitive calls, and make sure the pool can degrade safely if RPC becomes unavailable.
- Reorg-safe accounting: design credit reversal and operator alerts so reorganizations don’t become manual spreadsheet incidents.
- Vardiff clarity: explain that variable difficulty adapts per worker and is tuned to control share rate and reduce stale submissions.
SWING pool stack: choose for observability and fail-safe behavior
SWING pools benefit from stacks that expose metrics cleanly. You want to see reject reasons, template refresh timing, and wallet errors without digging through unstructured logs.
- Yiimp deployment: quick portal and standard features. Use Yiimp setup guide then add strict monitoring and rollback procedures.
- Miningcore deployment: strong when you want explicit APIs and good telemetry. Start from Miningcore setup guide and wire metrics into your ops stack.
- Custom deployment: best when you need strict failover, multi-region Stratum edges, or custom authentication for miners.
If you anticipate high-latency miners, prefer a setup that can tolerate slow connections without stalling all workers.
SWING pool setup tasks (node → Stratum → payouts)
- Node builds: version management, service supervision, and a tested recovery path for reindex/rescan scenarios.
- RPC hardening: private interfaces, allowlists, and separate credentials per service so secrets can rotate without downtime.
- Stratum tuning: worker parsing, connection policies, and vardiff settings; vardiff here means per-worker share difficulty adjusts to maintain healthy share rates.
- Payout logic: batching, audit logs, and references to payout schemes plus the selection guide for SOLO vs PPLNS vs PROP.
- Operational visibility: status pages, alert routing, and clear indicators when payouts are paused due to chain issues.
- Security hardening: host/network controls, backups, and recommended practices from security hardening.
A stable SWING pool is one where your operational procedures are documented and tested—especially around payouts and chain events.
SWING miner quick-start: endpoints, workers, and passwords
Miners should not need to guess. Provide one worker format, and fail fast with a clear error message when the format is wrong.
stratum+tcp://POOL-DOMAIN:3333
stratum+ssl://POOL-DOMAIN:3443
username: SWING_WALLET_ADDRESS.worker-east
password: x
If you require passwords for account login or per-worker tokens, document that separately from the Stratum “password” field, which most ASICs treat as a free-form string.
SWING-specific reliability notes (reorgs, peers, upgrades)
- Peer quality: track inbound/outbound peers and add stable nodes if the default peer set is unreliable.
- Upgrade cadence: treat daemon upgrades as change-controlled events and keep a rollback plan ready.
- Reorg policy: define how many confirmations you require and how far back you will reverse credits; test the reversal path on staging.
SWING deployment checklist for production
- Sync at least one node fully and verify RPC stability across restarts; record known-good outputs for core calls.
- Restrict RPC networking and confirm the website layer cannot reach wallet methods.
- Start Stratum, connect one miner, and validate share acceptance and reject logging.
- Run a payout simulation and confirm that the wallet can construct the transaction under your intended batching policy.
- Add alerts for chain tip drift, wallet lock errors, payout job failures, and spikes in rejects/stales.
- Create and test the incident playbook: pause payouts, investigate, resume, and communicate status to miners.
- Go live gradually and widen limits only after you have real monitoring data.
Swing pool FAQ (engineering answers)
How do you confirm SWING is actually mineable with your pool stack?
You validate by building the daemon you will run, syncing it, and testing getblocktemplate/submitblock flows (or the equivalent your pool core uses). If templates or submissions behave oddly, you stop and investigate before publishing endpoints.
What is the recommended approach to reorgs for SWING payouts?
Use a confirmation buffer and make credits reversible. The pool must log block-to-round mappings so you can explain reversals without manual reconstruction.
Can SWING run with TLS-only Stratum?
Yes, if your miners support it and your TLS termination is sized correctly. TLS can reduce credential leakage on untrusted networks, but it adds CPU cost; monitor it.
Why do some miners show “low difficulty share” errors?
It usually means the pool’s expected difficulty is higher than the miner is submitting, often due to vardiff minimums or a worker connecting to the wrong port.
Do you provide documentation and status pages for SWING miners?
Yes. Clear docs and honest status indicators reduce support load and help miners self-diagnose connection and payout issues.
