What is
Difficulty Adjustment Algorithm (DAA)?
The mechanism that adjusts mining difficulty to maintain consistent block times. Ergo adjusts difficulty every epoch to target ~2 minute blocks.
The Difficulty Adjustment Algorithm (DAA) automatically adjusts how hard it is to mine blocks based on network hash rate changes. When more miners join, difficulty increases to maintain target block times; when miners leave, difficulty decreases. Ergo uses a sophisticated DAA that adjusts every epoch (1024 blocks) to maintain approximately 2-minute block intervals. This ensures consistent transaction throughput and predictable confirmation times regardless of how much mining power is on the network.
Key Points
- Automatically adjusts mining difficulty
- Maintains consistent ~2 minute block times
- Adjusts every epoch (1024 blocks)
- Responds to hash rate changes
- Ensures predictable confirmation times
- Prevents blocks from being too fast or slow

Technical Details
Ergo's DAA calculates the average block time over the previous epoch and adjusts difficulty proportionally. If blocks were mined faster than 2 minutes on average, difficulty increases; if slower, it decreases. The algorithm smooths adjustments to prevent oscillation. This differs from Bitcoin's 2-week adjustment period, making Ergo more responsive to hash rate changes while avoiding instability.

Common questions about this topic
How to get started with Ergo?
Start by getting a wallet (Nautilus for browser, Terminus for mobile). Back up your seed phrase securely offline. Get some ERG from a current exchange or verified venue, then make a small test transaction. After that, explore NFTs, mining, DeFi references, or the developer stack if you're a builder.

What can I do with Ergo?
Ergo supports a broad ecosystem: use SigmaUSD, explore historical and current DeFi references, mix transactions with ErgoMixer where lawful, collect NFTs, mine with GPUs, bridge to other chains via Rosen, and build dApps with ErgoScript. Always verify current project status before sending funds to a third-party app.

How to provide liquidity on Ergo?
Providing liquidity on Ergo depends on the current active DEX or AMM venue. In general, you deposit equal value of two assets into a pool, receive LP tokens representing your share, and earn a portion of trading fees. Spectrum Finance is historical/frozen since February 2024, so verify the active venue, contracts, liquidity depth, and withdrawal process before depositing funds.

What is Autolykos and how does it work?
Autolykos is Ergo's memory-hard Proof-of-Work algorithm designed for GPU mining. It requires significant RAM (currently ~2.5GB), making ASIC development uneconomical. Autolykos v2 (current version) allows pool mining while maintaining ASIC resistance. The algorithm promotes decentralization by keeping mining accessible to consumer hardware.
