How to mine Handshake (HNS)? (Blake3 Algorithm)

Mining Hardware Requirements

1. Handshake mining relies on the Blake3 hashing algorithm, which is highly optimized for CPU and GPU parallelism but favors CPUs with high single-thread performance and large cache hierarchies.

2. Modern x86-64 CPUs such as AMD Ryzen 7/9 or Intel Core i7/i9 series deliver competitive hashrates due to Blake3’s low memory latency sensitivity and efficient instruction-level parallelism.

3. GPUs are technically compatible but rarely used in practice because Blake3 does not benefit significantly from massive thread counts or VRAM bandwidth—unlike SHA-256 or Ethash.

4. ASICs for Blake3 remain scarce; no widely adopted, commercially available Handshake-specific ASIC miners exist as of current network conditions.

5. RAM requirements are modest—typically under 2 GB—and system stability depends more on thermal management and consistent clock speeds than raw capacity.

Software Setup Process

1. The official Handshake client hnsd must be installed alongside a compatible miner such as handshake-miner or community-maintained forks supporting Blake3.

2. Users compile the miner from source using Rust toolchain (rustc 1.70+), as prebuilt binaries are not officially distributed by the Handshake Foundation.

3. Configuration involves specifying the RPC endpoint of a local hnsd node, wallet address for payouts, and thread count aligned with CPU core availability.

4. A fully synced hnsd node is mandatory—not just headers, but full UTXO state—to validate candidate blocks and submit valid proofs-of-work.

5. Stratum proxy support is limited; most miners connect directly to localhost RPC, requiring proper authentication tokens generated via hnsd’s configuration file.

Network Consensus Mechanics

1. Handshake uses a Nakamoto-style PoW with dynamic difficulty adjustment every 2016 blocks, targeting ~10-minute block intervals.

2. Each block header includes a Blake3 hash of concatenated fields: version, previous block hash, merkle root, timestamp, bits, and nonce.

3. The target threshold is encoded in “bits” and recalculated based on observed time variance across the adjustment window—not arithmetic mean but median time past.

4. Block rewards began at 2,000 HNS per block and halve approximately every four years; the first halving occurred at block 1,051,200.

5. Transaction fees are optional and not required for inclusion, though miners may prioritize higher-fee transactions when constructing blocks.

Pool Mining Considerations

1. Centralized pools like HNSPool and HandyPool operate using custom stratum protocols adapted for Blake3’s fast hash iteration.

2. Payout models vary: some use Pay-Per-Share (PPS), others Propotional (PROP) or Pay-Per-Last-N-Shares (PPLNS), with minimum thresholds ranging from 0.1 to 5 HNS.

3. Pool operators maintain their own full nodes and verify all submitted shares against consensus rules before crediting miners.

4. Connection stability is critical—Blake3’s rapid hash rate means stale shares accumulate quickly if network latency exceeds 500ms.

5. No pool implements merged mining with Bitcoin or other chains, as Handshake’s design intentionally isolates its consensus layer from external dependencies.

Frequently Asked Questions

Q: Can I mine Handshake using a Raspberry Pi?A: Yes, but profitability is negligible. A Raspberry Pi 4 (8GB) achieves ~1.2 MH/s—orders of magnitude below break-even electricity cost thresholds on mainnet.

Q: Is GPU mining supported via OpenCL or CUDA?A: Blake3 implementations exist for both, yet no production-grade miner integrates them meaningfully. Hash efficiency drops sharply beyond ~16 parallel lanes on GPU due to memory coalescing overhead.

Q: Does Handshake support solo mining without a pool?A: Absolutely. Solo mining is fully functional provided the operator runs a synced hnsd node and configures the miner to submit directly to its RPC interface.

Q: Are there known vulnerabilities in Blake3 affecting Handshake mining security?A: Blake3 is cryptographically sound with no known collisions or preimage attacks. Its design eliminates weaknesses present in earlier Blake variants, and Handshake’s implementation follows RFC 9106 without modification.
