Yiimp Mining Pool Setup for SHA256 Coins — Production Deployment Guide
This page is for operators deploying Yiimp as a service, not as a weekend experiment. The focus is reproducible builds, locked-down wallet/RPC access, Stratum stability under mixed traffic, and a handover runbook you can actually use.
When Yiimp is the right hammer
Yiimp is a solid choice when you want an integrated portal + payout engine and you are comfortable operating a LEMP-style stack with a MySQL-backed share database. It shines for operators who value a familiar miner UI and quick iteration on coin additions or pool branding.
If you are building a very large public pool with multiple Stratum gateways, strict SLA requirements, or heavy customization in accounting, you may still use Yiimp—but you should treat it as a starting point and plan for additional engineering around isolation, observability, and deployment automation.
If you’re comparing platforms, read Yiimp vs Miningcore (SHA256) and then choose based on your operating model, not forum opinions.
Planning the Yiimp footprint: servers, storage, and network
- Compute layout: separate Stratum entrypoints from wallet/RPC where possible; keep the blast radius small if a public-facing host is abused.
- Storage strategy: plan disk IO for share writes and database growth; retention and indexing are operations decisions, not afterthoughts.
- Network posture: assume hostile traffic if the pool is public: firewall defaults, DDoS-aware routing, and explicit rate limits at the edge.
- Storage: the database grows over time; plan disk + backups from day one.
If the pool accepts connections from the public internet, treat every exposed port as an attack surface. Build with least privilege, isolate wallet RPC, and instrument the system so you can see failure modes quickly.
Yiimp build scope: Stratum, portal, payouts, observability
- Stratum policy: ports, varDiff (variable difficulty), banning rules, and compatibility tests across ASIC firmwares and proxies.
- Daemon and wallet layer: node deployment, RPC hardening, and safe handling of pool-controlled funds and payout batching.
- Database and accounting: share retention, round calculations, and backup/restore drills that preserve payout integrity.
- Portal and UX: miner dashboards, worker charts, API endpoints, and status pages that reduce support load.
- Monitoring and alerts: metrics for stale shares, rejected blocks, daemon drift, and database health—plus actionable alert thresholds.
Example: Stratum connection strings (what miners see)
Your pool will typically advertise connection strings like:
stratum+tcp://your-domain.com:3333
stratum+tcp://your-domain.com:443 (TLS/alternative port)Exact ports and TLS termination depend on your edge design. We document the final endpoints, worker format, and any port-tier guidance for farms vs rental hashpower.
Failure modes we engineer around in Yiimp
- Rejected blocks: often caused by daemon misconfiguration, stale templates, or incorrect time/peer state. We instrument template generation and submission so root causes are visible.
- Share-accounting drift: typically a database or service restart issue. We ensure deterministic round accounting and verify it via replay tests.
- Wallet surprises: rescans, stuck transactions, or immature spends can break payouts. We build payout holds and provide a manual approval path.
- Undocumented changes: pools break after “small tweaks.” We keep configs versioned and provide a change procedure with validation steps.
- No incident plan: operators need a playbook for DDoS events, daemon reindex, and database recovery. We provide runbooks and drills.
Runbook and handover deliverables
- Runbook: restart/upgrade steps, log locations, and “what to check first” flows for the most common incidents.
- Secrets and access: credential rotation guidance, least-privilege access lists, and a break-glass procedure.
- Backup plan: database backup schedule, restore test steps, and recovery time expectations.
- Validation checklist: post-change tests that confirm Stratum accepts shares, blocks submit correctly, and payouts are safe.

Yiimp setup FAQ for SHA256 pool operators
Can Yiimp run a single-coin SHA256 pool without multi-coin clutter?
Yes. Yiimp can be deployed for one coin with a streamlined portal. We remove unused pages and configure only the services you need for that one chain.
Do you deploy Yiimp behind a reverse proxy or dedicated Stratum gateway?
In production, yes. We typically place web assets behind a reverse proxy and put Stratum behind a gateway layer so you can apply rate limits, TLS termination, and DDoS controls without touching the wallet hosts.
How do you tune varDiff for ASIC farms versus rental hashpower in Yiimp?
We separate port tiers and tune varDiff (variable difficulty) targets so farms submit steady shares while rental-style clients don’t flood the server with tiny shares or reconnect loops.
What backup strategy works for Yiimp databases and shares?
We back up MySQL with tested restore procedures and define retention so share tables don’t grow forever. The goal is being able to restore the pool and still explain payouts.
Why do some pools show 'rejected blocks' even when miners seem fine?
Common causes are stale templates, time drift, bad peers, or misconfigured daemons. We log template generation and submission paths so you can distinguish miner issues from node issues.
Do you keep wallet RPC off the Stratum server?
Whenever practical, yes. Wallet RPC is a high-risk interface, so we isolate it, restrict network access, and keep secrets out of the web/Stratum tier.
Can you migrate an existing Yiimp installation to new hardware?
Yes. We treat migration as a controlled cutover: clone databases with verification, preserve configs and secrets, validate endpoints, and then switch DNS/ports once the new stack is proven.
Is a one-click Yiimp install script safe for production?
Install scripts can speed up a lab build, but production requires review: pinned versions, hardened configs, monitored services, and a recovery plan. We can start from a script and then productionize the result.
