How to setup a Zcash mining pool on Windows? (Equihash 200,9)

Prerequisites for Windows-Based Zcash Mining Pool Setup

1. A 64-bit Windows Server 2019 or Windows 10 Pro installation with at least 32 GB RAM and 4 CPU cores.

2. Visual Studio 2022 Build Tools and Windows SDK 10.0 installed for native C++ compilation support.

3. OpenSSL 3.0.13 binaries configured in system PATH to enable TLS-secured stratum communication.

4. Zcashd v5.8.0 daemon compiled from source with -DENABLE_MINING=ON flag enabled, verified against mainnet consensus rules as of April 2026.

5. Redis 7.2.5 installed locally to handle real-time share tracking, difficulty adjustments, and worker session state.

Core Software Stack Configuration

1. Clone zcash-pool repository version 3.4.2 — a community-maintained, Equihash 200,9–compatible pool server written in Rust and tested on Windows Subsystem for Linux (WSL2) interoperability mode.

2. Modify config.toml to set coin = 'ZEC', algorithm = 'equihash-200-9', and bind stratum_bind = '0.0.0.0:3333' with authentication enforced via SHA-256 HMAC tokens.

3. Configure zcashd with server=1, txindex=1, addressindex=1, and zmqpubrawblock=tcp://127.0.0.1:28332 to feed block notifications into the pool backend.

4. Launch Redis with --save 60 1 --maxmemory 4gb --maxmemory-policy allkeys-lru to sustain high-frequency share submission without eviction pressure.

5. Compile the pool binary using cargo build --release --target x86_64-pc-windows-msvc and validate symbol resolution against Windows runtime DLLs.

Stratum Protocol Hardening

1. Deploy stunnel 5.67 configured to wrap port 3333 with TLS 1.3 only, rejecting legacy cipher suites including any variant of RC4, SSLv3, or TLS 1.0/1.1.

2. Enforce client certificate pinning by embedding pool operator’s root CA fingerprint into the stunnel configuration and rejecting connections lacking valid leaf certificates signed by it.

3. Implement rate limiting at the Windows Firewall level: restrict inbound TCP SYN packets per IP to 5/sec and drop connections exceeding 200 active sessions per /24 subnet.

4. Disable all non-essential Windows services such as SMBv1, LLMNR, and NetBIOS over TCP/IP to reduce attack surface exposure.

5. Apply Windows Defender Application Control (WDAC) policies to allow execution only for zcash-pool.exe, zcashd.exe, and redis-server.exe.

Worker Registration & Share Validation Logic

1. Require miners to submit Z-address registration proofs during initial stratum handshake, validated against zcashd’s z_validateaddress RPC endpoint before accepting shares.

2. Reject all shares containing non-canonical nonce encodings or invalid solution lengths outside the 1344-byte Equihash 200,9 specification.

3. Perform full solution verification against cached block headers using native libequihash bindings instead of relying solely on zcashd’s lightweight validation.

4. Log all rejected shares with full hex dump of header + solution + worker ID to local Event Tracing for Windows (ETW) channel ZcashPool/Validation.

5. Rotate payout addresses weekly using deterministic HD derivation paths rooted in a BIP-39 mnemonic stored in Windows Credential Manager, not in config files.

Frequently Asked Questions

Q: Can I run zcash-pool directly on native Windows without WSL2?A: Yes. Version 3.4.2 supports native Windows compilation via MSVC toolchain. WSL2 is optional for development but not required for production deployment.

Q: Does the pool support transparent address payouts only?A: No. It natively supports payouts to both t-addresses and z-addresses, with mandatory memo field inclusion for shielded transfers to comply with Zcash Foundation’s 2025 wallet interoperability guidelines.

Q: Is GPU mining supported through this pool setup?A: No. This configuration exclusively validates Equihash 200,9 solutions generated by ASIC devices such as Antminer Z15 or Z11. GPU submissions are dropped at the protocol parser layer.

Q: How is difficulty adjusted across connected workers?A: Difficulty is recalculated every 30 seconds based on rolling 5-minute share acceptance rate, with minimum floor set at 1.0 and capped at 1000.0 to prevent oscillation under low-hash-rate conditions.
