Dollarcoin (DLC) SHA256/SHA256d Mining Pool Setup — Wallet & Mempool Aware
Because Dollarcoin 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 DLC mining pool: node/RPC, Stratum behavior, payouts, and public documentation.
DLC pool operations: shares are easy, payouts are the job
Standing up the Stratum gateway is the quick part. The real operational work for Dollarcoin is payment flow: a payout wallet accumulates UTXOs, transactions need fees, and miners expect timely, explainable payments.
- Payment workflow: define how often you pay, how you batch, and what you do when a transaction is delayed or stuck.
- Wallet hygiene: keep keys protected, backups automated, and recovery steps documented before you onboard miners.
- Mempool awareness: understand how your node relays and confirms pool payouts so you don’t accidentally create “unspendable” tiny outputs.
- Support readiness: publish troubleshooting that maps to real logs (invalid address, low difficulty shares, banned clients).
Choosing software for DLC: Yiimp vs Miningcore
DLC pools can run on standard SHA256 tooling. We focus on the engine that best supports your operational style: UI workflows and quick onboarding, or service separation and API integration.
- Yiimp-based: Good for a familiar miner dashboard; Yiimp setup guide is the usual choice when you want a classic pool website fast.
- Miningcore: Ideal when you want a clean backend and structured configuration; start with the Miningcore setup guide method and tune from there.
- Custom stack: Use a custom stack when you need specialized payment rules, custom reporting, or non-standard authentication.
As the pool grows, payout batching and wallet maintenance become continuous work. Plan for monitoring around transaction creation, broadcast, and confirmation.
DLC pool configuration: services, storage, and controls
- DLC node layer: daemon install, supervised services, and RPC limited to pool hosts only.
- Pool core + database: share/block tracking, retention controls, and backups sized to your pool’s share volume.
- Stratum endpoints: port roles, VarDiff (variable difficulty) targets, bans/limits, and miner docs tuned for support efficiency.
- Payout pipeline: wallet signing, batching, fee handling, and a chosen payout model (see payout schemes and how to choose SOLO vs PPLNS vs PROP).
- Website UI: miner dashboard pages that explain balances, pending payouts, and payment history clearly.
- Security hardening: firewalling, backups, secret rotation, and monitoring guidance (see security hardening).
We design DLC payout ops to be observable: you should be able to answer “why didn’t I get paid yet?” with a log line and a transaction ID, not guesswork.
DLC miner endpoint examples (and how to document them)
Keep miner docs consistent with your actual configuration. If you run multiple ports, describe what each one is for and who should use it.
stratum+tcp://POOL-DOMAIN:3333
stratum+ssl://POOL-DOMAIN:3443We recommend publishing a short “common errors” section so miners can fix configuration issues without opening tickets.
DLC-specific payout and fee-policy considerations
- Fee/relay policy: confirm how the DLC node relays payout transactions, then set batch behavior that confirms reliably.
- UTXO growth: design thresholds and batching to avoid creating endless tiny outputs over time.
- Recovery practice: run a wallet restore/rescan test before real balances accumulate.
DLC launch checklist (from empty wallet to first payment)
- DLC daemon synced and healthy; monitoring alerts on stalled tip and disk saturation.
- RPC firewalled and authenticated; wallet methods reachable only from pool services.
- Stratum ports validated with real miners; VarDiff stable and ban rules verified.
- Database backup and restore drill completed; share retention policies confirmed.
- Payout wallet funded for tests; batching creates valid transactions and broadcasts cleanly.
- Website shows balances and payments consistently; status indicators match actual state.
- Documentation includes endpoints, worker format, and a payments FAQ to reduce support overhead.
DLC pool build FAQ (operator-focused)
How do you keep DLC payouts from becoming a wallet-management mess?
We design batching and thresholds to keep the wallet healthy over time, and we add monitoring around transaction creation and confirmation so issues show up early.
Can you run a private DLC pool for a small mining group?
Yes. We can restrict registrations and Stratum access so the pool behaves like an internal service while still using the same payout accounting.
Do you tune DLC specifically for rented hashpower?
If you plan to accept marketplace miners, we create dedicated ports and stricter limits. That prevents reconnect storms from hurting normal miners.
What does VarDiff mean on a DLC pool?
VarDiff is variable difficulty: the pool adjusts share difficulty per miner to keep share submission rates predictable. We tune it so accounting stays stable.
What information do you need to begin a DLC setup?
Send your expected hashrate, your preferred engine, hosting details, and how you want to handle payouts (frequency, batching, and public UI needs).
