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 an exchange (Gate.io, KuCoin) or DEX (Spectrum). Make a test transaction. Then explore: try DeFi on Spectrum, check out NFTs, or dive into the technology if you're a builder.

How private is Ergo blockchain?

Ergo is not private by default like Monero, but offers powerful optional privacy tools. ErgoMixer provides non-interactive, non-custodial mixing. Sigma Protocols enable zero-knowledge proofs in smart contracts. Stealth addresses hide recipients. The key difference: Ergo's privacy is programmable - you choose when and how much to reveal.

What is storage rent on Ergo?

Storage rent is Ergo's solution to state bloat. Boxes (UTXOs) that remain unspent for 4+ years can have a small fee deducted by miners. This incentivizes cleaning up unused state, provides long-term miner revenue after emission ends, and keeps the blockchain sustainable. Lost coins eventually return to circulation instead of being locked forever.
