ParkByte (PKB) SHA256/SHA256d Pool Setup — Legacy-Chain Playbook
Older SHA256 chains often fail at the boring parts: compiling a working daemon, staying synced, and keeping the wallet responsive. This guide covers how we launch a ParkByte (PKB) SHA256/SHA256d pool with a focus on deterministic node behavior and recoverable operations.
ParkByte pool setup for a legacy chain: keep it deterministic
PKB-style legacy coins tend to have older dependencies, slower sync behavior, and wallets that dislike heavy RPC usage. The operator goal is to make the node predictable: stable service restarts, repeatable bootstrap, and a payout flow that doesn’t depend on fragile manual steps.
- Daemon provenance: Identify the canonical source/build and pin versions so your pool can be reproduced after a crash or migration.
- Sync strategy: Plan for initial sync time and disk usage; keep a tested reindex path for corruption scenarios.
- Wallet load control: Limit RPC concurrency and batch payouts to avoid wallet lockups during peak share processing.
- Documentation clarity: Legacy chains attract inconsistent miner configs; publish strict worker rules and reject reasons.
PKB stack choice: minimize moving parts
For PKB, simpler is often better. Choose a stack you can fully observe and rebuild quickly when the inevitable node maintenance event occurs.
- Yiimp-based: Works when you want a classic pool site; keep dependencies pinned and document deployment steps. See Yiimp setup guide.
- Miningcore: Works when you prefer a modern service model and want clean separation of components. See Miningcore setup guide.
- Custom approach: Useful when the PKB daemon needs special handling for template generation or wallet RPC quirks.
We throttle wallet RPC calls and implement payout batching so the wallet isn’t hammered every minute. We also document recovery steps (backup, rescan, reindex) so operators can restore without improvising.
PKB pool setup scope (build through payouts)
- PKB node build: Compile/install, dependency pinning, sync validation, and service hardening.
- Data and backups: DB configuration plus on-disk node data backups with verification restores.
- Stratum services: Ports, timeouts, VarDiff (variable difficulty), and ban rules suitable for ASIC traffic.
- Payout pipeline: Batching policy, threshold rules, and safe re-run behavior. See payout schemes and SOLO vs PPLNS vs PROP.
- UI and reporting: Miner stats with reject breakdowns and payment history suitable for audits.
- Security and ops: Private RPC, limited SSH access, and monitoring alerts. See security hardening.
If PKB requires special Berkeley DB handling or specific wallet.dat formats, we document that explicitly and keep the required packages pinned to avoid “works on one server” failures.
PKB miner connection strings and documentation tips
Use the standard endpoint format and keep worker naming strict. For legacy coins, “garbage input” from miners is common; validation saves your operators.
stratum+tcp://POOL-DOMAIN:3333
stratum+ssl://POOL-DOMAIN:3443We publish a short list of common misconfigurations (bad address, invalid worker suffix, proxy settings) to reduce support load.
ParkByte-specific notes: legacy daemon and wallet handling
- Build dependencies and reproducibility: Older daemons may require specific compiler and library versions. We capture the build steps and package versions so you can rebuild later.
- Bootstrap and reindex planning: Have a tested reindex procedure and enough disk IO headroom; corruption recovery should be routine, not a crisis.
- Wallet performance under batching: Test sendmany behavior with realistic batch sizes; tune payout cadence so payments confirm without overwhelming the wallet.
PKB go-live list
- Daemon build process documented and reproducible on a clean server.
- Initial sync completed and reindex procedure tested once before going public.
- RPC access isolated; wallet backups taken and verified by restore.
- Stratum validated under burst traffic; ban logic confirms expected behavior.
- VarDiff tuned for both small test miners and high-hash ASICs.
- Payout batching tested with real small payments and a simulated failure restart.
- Miner documentation published with strict input rules and reject explanations.
ParkByte pool Q&A
Can you help compile and run a legacy PKB daemon reliably?
Yes. We pin dependencies, produce repeatable build steps, and set up restart-safe services so the node behaves predictably across reboots.
How do you prevent the PKB wallet from locking up during payouts?
We batch payments, limit RPC concurrency, and monitor wallet RPC latency. If latency rises, payouts can be paused automatically or manually without losing accounting state.
Do you support a small private PKB pool for a single farm?
Yes. Private pools are common for legacy chains. We can restrict Stratum by IP/VPN and keep the UI minimal while still producing auditable payout records.
What if the chain needs frequent reindex or rescan operations?
We plan for it. The runbook includes reindex/rescan steps, expected resource usage, and alerts that indicate when indexing drift is happening.
What information helps you scope a PKB pool setup?
Expected miner count/hashrate, desired payout model, hosting environment, and whether you want a public website UI or an internal dashboard only.
