Freicoin (FRC) SHA256/SHA256d Mining Pool Setup — Wallet Policy & Payout Safety
Freicoin uses SHA256/SHA256d mining, so a pool can accept ASIC hashrate. The operational challenge is wallet discipline: payouts must be repeatable, verifiable, and resilient to chain events.
FRC risk model: where pools usually fail
An FRC pool is exposed to two classes of problems: chain-level events (stale tips, reorgs, slow nodes) and wallet-level events (spends failing, stuck transactions, inconsistent fee selection). You avoid both by making behavior explicit and testable.
- Maturity handling: “Maturity” is the confirmation rule for when rewards can be spent; the pool must not pay out immature funds.
- Spend policy: Define how you select UTXOs, when you batch, and how you recover from a broadcast failure.
- Node redundancy: Keep the daemon stable and observable; a silent desync is more dangerous than an obvious crash.
- Ledger reconciliation: Ensure the pool’s internal ledger can be compared against on-chain data at any time.
FRC software path: choose the pool core you can maintain
For FRC, pick a pool stack that matches how you want to operate upgrades, monitoring, and wallet integration.
- Yiimp-based: Often chosen for a quick UI-first launch and a familiar pool website. See .
- Miningcore: Often chosen for a cleaner service boundary between Stratum, payouts, and the API/UI layer. See .
- Wallet-first customization: If wallet spend control is your priority, we can harden payout jobs and signing workflows regardless of which pool core you choose.
Treat payout jobs like payments infrastructure: logs, retries, and idempotency matter more than fancy dashboards.
FRC implementation plan (node, Stratum, payouts, UI)
- FRC node + RPC hardening: Install the daemon, confine RPC to a private interface, and confirm the required RPC methods for templates and block tracking.
- Share ingestion: Configure share processing and database indexes for your expected hashrate and share frequency.
- Stratum ports + limits: Expose a minimal port set, define timeouts, and tune vardiff for stable share arrival.
- Payout pipeline: Implement batching, threshold rules, and failure recovery; reference and .
- UI + operator views: Provide miner-facing stats and operator-only reconciliation views for FRC payouts and blocks.
- Security + backups: Harden hosts, rotate secrets, and test restores; see .
If you are running several SHA256 coins, we isolate FRC wallet keys and payout workers so a stuck transaction cannot stall other coins’ payout schedules.
FRC miner endpoints and how to document them
Your miner setup page for FRC should answer three questions: where to connect, what username to use, and what to do when the miner shows rejects.
stratum+tcp://POOL-DOMAIN:3333
stratum+ssl://POOL-DOMAIN:3443Consider a separate operator appendix for pool-side settings (vardiff targets, connection caps, and log locations).
FRC-specific wallet notes: spending rules and confirmations
- FRC confirmation policy: Document how many confirmations you require before crediting blocks and before spending rewards; then enforce that rule in code.
- FRC wallet key handling: Decide whether the hot wallet signs directly on the pool host or via a separate signing machine; both are possible, but you must choose intentionally.
- Fee and mempool behavior: If payouts stick unconfirmed, review daemon fee/relay settings and adjust batching or fee selection—always test on small amounts first.
FRC launch discipline checklist
- Run the FRC daemon under supervision (health checks + restart policy) and alert on sync lag immediately.
- Validate block crediting: found blocks, orphans, and reorg rollbacks should be reflected in balances without manual edits.
- Prove payout idempotency: re-run the same payout job after an injected failure and confirm it does not duplicate payments.
- Tune vardiff to keep share throughput steady while staying within DB capacity.
- Create clear miner docs with one canonical username format and one tested address example.
- Lock down RPC access and rotate secrets before you announce the FRC pool publicly.
- Back up wallet material and the accounting database; perform a full restore drill in staging.
FRC pool FAQs
What’s the safest default payout approach for an FRC pool?
Start conservatively: higher payout thresholds, batching, and strict confirmation rules. We then iterate based on real traffic and on-chain fee behavior.
How do you handle FRC block maturity in the payout engine?
We implement maturity gates so blocks are credited and spendable only after the configured confirmations. Orphans and reorgs trigger an automatic rollback path.
Can you separate the FRC hot wallet from the pool servers?
Yes. Many operators prefer signing outside the Stratum/web hosts. We can integrate a remote signing workflow while keeping the pool’s accounting consistent.
Do miners need special settings to mine FRC?
Miners generally use standard SHA256 Stratum URLs. The important part is the correct username/address format and stable difficulty behavior.
How do you diagnose stuck FRC payout transactions?
We inspect mempool acceptance, fee settings, and UTXO selection. The fix is usually batching/fee policy, not changing the pool core.
