Donu (DONU) SHA256/SHA256d Mining Pool Setup — Conservative, Testable Rollout
A Donu pool on SHA256/SHA256d succeeds when the “boring” parts are correct: synced nodes, predictable difficulty behavior, and safe payouts. Below is our operator‑focused checklist for launching and maintaining a DONU pool.
DONU pool setup: control drift and keep configs testable
Donu pool deployments go smoothly when you treat everything as a pinned artifact: daemon version, config files, database migrations, and Stratum policy. That makes troubleshooting repeatable and reduces the risk of “it changed overnight.”
- Version control: pin your DONU daemon build and document upgrade steps so the pool doesn’t drift silently.
- Access boundaries: isolate wallet RPC from the public internet and separate operator actions from automated services.
- Share validation: make rejects explainable (bad worker format, invalid address, stale work) to cut support time.
- Launch discipline: start private, prove payouts, then widen access as monitoring proves stable.
DONU pool software selection (Yiimp, Miningcore, or custom)
We can run DONU on Yiimp or Miningcore, but we choose based on the operational workflow you want. The best engine is the one you can maintain without surprises.
- Yiimp-based: A practical choice when you want a ready-made website; the Yiimp setup guide path is common for UI-heavy pools.
- Miningcore: Works well when you prefer an API-first backend; begin from the Miningcore setup guide layout and harden for production.
- Custom stack: Choose custom when you need special miner authorization, bespoke accounting, or multi-region Stratum gateways.
If DONU upgrades are frequent, build an upgrade lane: staging node, staging stratum, and a rollback plan. Production should never be your test environment.
DONU deployment scope: nodes, Stratum, database, UI
- DONU node layer: installation/build, supervised services, and RPC locked to the pool network.
- Pool core + database: share accounting, block tracking, and retention configured for your expected share rate.
- Stratum endpoints: ports, VarDiff (variable difficulty) bounds, bans/limits, and miner docs aligned to your worker rules.
- Payout pipeline: wallet signing workflow and payout scheme decisioning (see payout schemes and how to choose SOLO vs PPLNS vs PROP).
- Website UI: a branded DONU landing page and dashboard whose numbers match the ledger.
- Security hardening: backups, secrets, monitoring, and incident notes aligned to the hardening guide (see security hardening).
For DONU we emphasize reproducibility: if you redeploy from scratch, you should get the same behavior and the same accounting outcomes.
DONU miner connection strings and onboarding pattern
Keep onboarding simple. Publish the minimum endpoints and show a single “known-good” example configuration for common ASIC stacks.
stratum+tcp://POOL-DOMAIN:3333
stratum+ssl://POOL-DOMAIN:3443We recommend documenting what your pool considers a valid worker name and how it maps to account tracking, so miners don’t invent formats that break payouts.
DONU coin-integration checks: RPC, wallet, and crediting rules
- RPC compatibility: confirm the DONU daemon supports the template/submission calls your engine uses, then lock versions.
- Wallet security: decide how signing happens, where keys live, and how you recover from a wallet database issue.
- Fork response: monitor chain events that invalidate templates and document operator steps for recovery.
DONU production checklist (what to verify before inviting miners)
- DONU node synced and stable; monitoring alerts on stalled tip and peer loss.
- RPC isolated and authenticated; wallet functions accessible only to the payout service.
- Stratum ports tested with multiple miners; VarDiff and bans behave under reconnect tests.
- Database backups verified with a restore; share retention and pruning validated.
- Payout cycle rehearsed with small-value payments and reconciliation against balances.
- Public docs ready: endpoints, worker format, and a short troubleshooting section.
- Staged launch plan prepared with rollback steps and operator on-call notes.
DONU pool FAQ for implementers
Do you pin specific DONU daemon versions for pool stability?
Yes. We treat the daemon as a dependency that must be versioned. We document upgrade steps and test upgrades in staging before touching production.
Can you deploy DONU as a private pool with restricted access?
Yes. We can limit registrations, restrict Stratum by IP, and keep payout operations operator-controlled until you’re ready to open it up.
How do you validate DONU share crediting is correct?
We run controlled tests: submit shares, confirm ledger entries, then execute a payout cycle and reconcile the wallet transactions against recorded balances.
What does VarDiff do for DONU miners?
VarDiff adjusts per-miner share difficulty so submissions stay within a predictable rate. That stabilizes database load and makes stats less noisy.
What do you need to start a DONU pool build?
Share your target pool type, hashrate expectations, preferred engine, and whether you want ongoing monitoring and maintenance after launch.
