Hydraledger (HYD) SHA256/SHA256d Mining Pool Setup — Indexing & Accurate Stats
Hydraledger pool operators typically spend more time on data plumbing than on Stratum itself. HYD uses SHA256/SHA256d mining, so the hard part is making stats, blocks, and payouts match what the chain reports—especially as the database grows.
HYD data correctness: make the dashboard match the chain
A HYD pool succeeds when miners can independently verify what they see: hashrate, shares, found blocks, and payments. That requires fast block/transaction lookup, consistent indexing, and a payout ledger that can be reconciled without guesswork.
- Indexing strategy: Decide what needs to be queryable (blocks, txs, addresses) and enable the node/indexers accordingly.
- Retention policy: Plan how much share history you keep and how you archive it so queries remain fast.
- Reconciliation: Build a repeatable report that ties pool balances to on-chain payouts.
- Operational observability: Track node tip, DB performance, and job latency; data drift is a reliability problem.
HYD stack choice for long-term maintainability
For HYD, the stack decision is as much about data access patterns as it is about Stratum performance.
- Yiimp-based: Works well when you want a classic UI quickly, but you must size DB and indexes for growth; see .
- Miningcore: Works well when you want a clean API for stats and can separate services cleanly; see .
- Indexing add-ons: If you need heavier explorer queries, we can add dedicated indexers and keep Stratum services isolated.
A beautiful dashboard is useless if it’s slow or inconsistent—optimize queries and indexing before you optimize CSS.
HYD build scope: nodes, indexing, payouts, and UI
- HYD node + RPC exposure control: Install the daemon, restrict RPC, and add health checks that include block/tx lookup performance.
- Share DB design: Index the hot paths (shares, workers, rounds) and define retention so growth stays predictable.
- Stratum endpoints: Set ports, timeouts, and vardiff behavior; define varDiff (variable difficulty) once in docs so miners understand changes.
- Payout reconciliation: Generate payout exports and reconciliation views; reference and .
- Explorer-style views: Surface blocks/txs in the UI using node RPC (or an indexer) so miners can click through and validate.
- Security + maintenance: Harden hosts, rotate keys, and monitor; see .
HYD can run alongside other SHA256 coins, but database isolation is key: each coin’s share history grows differently, so keep schemas and retention knobs separate.
HYD miner endpoints and minimal docs
For HYD, publish endpoints and one username example, then link to a page explaining where miners can verify blocks and payments in the UI.
stratum+tcp://POOL-DOMAIN:3333
stratum+ssl://POOL-DOMAIN:3443If you operate an API-only pool, keep the same information available as a simple JSON endpoint for automation.
HYD data notes: explorer lookups and retention planning
- HYD block/tx lookup performance: Test `getblock`/`getrawtransaction` (or equivalents) under load; slow lookups will make your UI feel broken even when mining is fine.
- Retention and archiving plan: Decide how long to keep share details and how to roll old data into aggregates without losing auditability.
- Payout export format: Define a stable export (CSV/JSON) for HYD payouts so you can reconcile deposits, support tickets, and accounting quickly.
HYD launch checklist for accurate reporting
- Benchmark HYD block/tx lookup calls and add alerts when latency rises.
- Size the database for share volume and enable indexes before miners arrive.
- Verify that dashboard totals reconcile against payout exports and on-chain transactions.
- Test Stratum ports with real miners and confirm difficulty updates behave as documented.
- Run a low-value payout test and ensure the UI links to verifiable chain data.
- Set backup + restore drills for both DB and wallet material, then document the procedure.
- Add monitoring for tip lag, DB slow queries, and API error rates so data drift is caught early.
HYD pool FAQs
Why does a HYD pool need indexing and “explorer-style” lookups?
Miners trust pools that are verifiable. Fast block/tx lookup lets the UI show evidence for found blocks and payments instead of vague totals.
Can you keep HYD share history without the database growing forever?
Yes. We define retention and aggregation policies so you keep auditability while controlling storage growth.
Do HYD miners need special connection settings?
Most miners just need the correct URL and username format. The pool-side work is making difficulty updates and stats consistent.
What’s the best way to reconcile HYD payouts?
Use a stable payout export and link every payment batch to its on-chain transaction(s). We build reports that make disputes easy to resolve.
Can HYD run in the same infrastructure as other SHA256 coins?
Yes, with isolation: separate wallets, separate schemas, and independent payout workers prevent one coin’s data load from affecting another.
