Unobtanium (UNO) SHA256 Mining Pool Setup — Reliability and Payout Integrity
UNO can be operated with the same core building blocks as other SHA256-family coins, but the pool still has to be defensible: consistent accounting, careful payout gating, and monitoring that catches node or wallet drift before miners do.
UNO pool operations: from share submission to payouts
In a UNO pool, Stratum is the miner-facing layer, but correctness lives underneath: the daemon must produce valid block templates, the pool must track shares deterministically, and the wallet must only spend outputs that are actually spendable. “Works on my server” is not enough—operators need repeatable behavior across restarts and upgrades.
- Access model: choose whether miners authenticate via accounts, static tokens, or a private allowlist—each choice changes abuse controls and support workload.
- Maturity handling: respect coinbase maturity (confirmations required before mined outputs can be spent) and build payout holds around it.
- Wallet hygiene: plan how you manage UTXOs and change outputs so payout batching does not degrade over time.
- Stratum tuning: use varDiff (variable difficulty) and reasonable limits so both small rigs and large farms submit steady shares without overloading the server.
UNO stack decision: classic Yiimp portal vs API-led Miningcore
A UNO pool can be launched fast, but you will feel the stack choice later when you need audits, upgrades, or custom payout behavior. We pick the platform based on operational clarity: how you observe it, recover it, and explain it to miners.
- Yiimp-based: good if you want an integrated website/portal quickly; follow the Yiimp setup guide and then apply UNO-specific wallet and monitoring rules.
- Miningcore: a service-oriented layout that is easy to automate; see the Miningcore setup guide if you prefer API-driven operations.
- Custom stack: useful for bespoke accounting/reporting, unusual authentication, or complex multi-server topologies.
Do not enable automatic payouts on day one. Start with manual payout approvals while you verify maturity rules, fee behavior, and accounting outputs against what the wallet reports over several rounds.
Hardening steps we apply for UNO stability
- UNO daemon layer: build/install, RPC protection, wallet configuration, and monitoring for sync drift, reindex events, and peer health.
- Share accounting: database sizing, share retention choices, and deterministic round calculations that survive restarts.
- Stratum endpoints: port strategy, vardiff calibration, miner compatibility testing, and clear documentation for worker naming.
- Payout gating: confirmation policy, batching rules, fee strategy, and safeguards. See the SOLO vs PPLNS vs PROP explainer to choose a payout model that matches your risk tolerance.
- Portal UX: a clean UNO landing page, miner dashboards, worker-level visibility, and transparency pages that reduce disputes.
- Security + recovery: network controls, secrets management, restore drills, and operational guidance from the security hardening page.
If you run UNO beside other SHA256 coins, we isolate payout state per coin and document the failure domains so one chain’s wallet issue does not pause payments for the entire pool.
UNO stratum endpoints and example connect strings
Keep UNO miner docs simple: show two endpoints (plain and TLS if offered), define the username format, and specify whether you accept worker suffixes. A small “invalid share” troubleshooting section saves hours of support time.
stratum+tcp://POOL-DOMAIN:3333
stratum+ssl://POOL-DOMAIN:3443We can generate a UNO-specific quick-start that maps common ASIC UI fields to your exact endpoints and worker convention.
UNO trust and settlement considerations for operators
- Confirmations policy: publish how many confirmations you require for blocks and payouts, and enforce it consistently. This reduces reorg-driven disputes.
- Wallet UTXO management: batch payouts in a way that keeps UTXO count sane; otherwise wallet operations can slow and make payouts unpredictable.
- Reorg response plan: decide how you detect reorganizations, when you pause payouts, and how you reconcile rounds when a block becomes orphaned.
UNO commissioning checklist before you announce
- UNO node and wallet services are stable across restarts; reindex/rescan procedures are documented.
- RPC is private-only, authenticated, and monitored for unexpected callers or rate spikes.
- Stratum is tested with multiple miner stacks; bans and limits do not penalize normal reconnect patterns.
- Round accounting is verified by replaying share data and confirming deterministic results.
- Payout logic is validated with manual approvals and then small automated batches after maturity holds.
- Backups are tested by restoring to a clean host and replaying at least one full payout cycle.
- Public pool docs cover: connect strings, worker format, payout model, and confirmations policy.
UNO pool FAQ for engineering and support
How do you choose UNO payout thresholds without burning fees?
We model payout frequency against transaction size and fee behavior observed on the chain. The safe approach is to start conservative, measure confirmation performance, and adjust thresholds while keeping miner communication clear.
If the UNO daemon needs a reindex, do we lose round history?
Round history lives in the pool database. A reindex affects the node’s view of chain data, so you pause payouts during the maintenance window and reconcile block status afterward using your recorded rounds.
How do you prevent double-paying when the wallet rescans?
By treating payouts as an auditable ledger: every batch is recorded, balances are reconciled against wallet outputs, and automated payouts stay disabled until post-rescan checks pass.
Can you run a private UNO pool with per-miner limits?
Yes. Access control can be account-based or allowlist-based, and you can enforce connection or hashrate policies at the Stratum layer depending on the behavior you need.
What documentation reduces UNO support tickets the most?
A single page that shows endpoints, username format, expected hashrate display delay, and a short list of common reject reasons (stale, low difficulty, unauthorized).
