How to mine Aeternity (AE)? (Cuckoo Cycle Guide)

Understanding Aeternity Mining Mechanics

1. Aeternity employs the Cuckoo Cycle algorithm, a memory-hard proof-of-work scheme designed to resist ASIC dominance and promote GPU-based decentralization.

2. The Cuckoo Cycle relies on finding cycles in sparse bipartite graphs, requiring large amounts of RAM for efficient graph traversal rather than raw computational throughput.

3. Unlike SHA-256 or Ethash, Cuckoo Cycle’s memory access patterns are irregular and non-cache-friendly, making optimization difficult for specialized hardware.

4. Aeternity’s implementation uses Cuckoo29 for mainnet, meaning miners must find cycles of length 29 in a graph with 2²⁹ edges — a threshold balancing security and accessibility.

5. Block time remains fixed at approximately 2.5 minutes, and difficulty adjusts every 100 blocks based on observed solve times across the network.

Hardware Requirements and Optimization

1. Minimum viable GPUs include NVIDIA GTX 1060 (6GB) or AMD RX 570 (4GB), though performance scales significantly with higher bandwidth and VRAM capacity.

2. System RAM must exceed 4 GB, but 8 GB or more is strongly recommended to avoid swapping during graph generation phases.

3. CPU selection matters less than memory bandwidth; modern dual-channel DDR4 systems outperform older quad-channel DDR3 setups due to latency-sensitive graph hashing steps.

4. Overclocking VRAM yields measurable gains—especially on GDDR6 cards—but core clock boosts offer diminishing returns beyond 10% increase.

5. Linux distributions such as Ubuntu 22.04 LTS provide better driver stability and lower background process interference compared to Windows for sustained mining sessions.

Setting Up the Mining Environment

1. Download the official Aeternity node software from the GitHub repository maintained by the Aeternity Foundation, ensuring verification via PGP-signed release tags.

2. Compile the cuckoopow library separately using Rust nightly toolchain, as prebuilt binaries may lack support for newer GPU architectures.

3. Configure the ae_mining.conf file with accurate pool endpoint, wallet address, and device-specific parameters like --cuda-devices or --opencl-platform.

4. Launch the miner binary with elevated memory locking privileges (mlockall) to prevent OS-level page swapping that disrupts cycle detection timing.

5. Monitor hashrate stability through the built-in JSON-RPC interface, polling /v2/mining/status at regular intervals to detect stalling or invalid share submissions.

Pool Selection and Reward Distribution

1. Major pools such as aepool.io and ae.hashvault.pro enforce strict identity verification for payout addresses to comply with anti-money laundering protocols embedded in Aeternity’s transaction layer.

2. Pools operate on PPLNS (Pay Per Last N Shares) models where N typically spans 200–500 shares, reducing variance without enabling pool hopping exploitation.

3. Each submitted solution undergoes cryptographic validation by the pool server before inclusion in the candidate block template, verifying both cycle correctness and nonce alignment.

4. Transaction fees collected in mined blocks are distributed proportionally among contributors alongside base block rewards, increasing effective yield during high-network-activity periods.

5. Pool-side difficulty adjustments occur every 30 seconds, dynamically scaling target thresholds to maintain consistent submission rates across heterogeneous hardware fleets.

Frequently Asked Questions

Q: Can I mine Aeternity using CPUs only?Yes, Cuckoo Cycle supports CPU mining, but hashrates remain below 1 sol/s on even high-end Threadripper systems—making it economically unviable without subsidized electricity.

Q: Does Aeternity support merged mining with other cryptocurrencies?No, Aeternity does not implement merged mining capabilities; its consensus layer operates independently and requires dedicated Cuckoo Cycle solutions.

Q: Why do my shares get rejected by the pool despite stable hashrate?Rejected shares often stem from clock drift between miner and pool servers, outdated stratum protocol versions, or misconfigured --coinbase-addr parameters that mismatch registered wallet identifiers.

Q: Is there a minimum payout threshold for AE rewards?Most pools enforce thresholds between 0.5 AE and 2.0 AE, enforced at the wallet level rather than network level, meaning balances below this amount accumulate until the condition is satisfied.
