What is
The number of blocks added after a transaction, indicating how secure/final it is.
Each block added after your transaction is a confirmation. More confirmations mean higher security - an attacker would need to rewrite more blocks to reverse your transaction. For Ergo, 10+ confirmations (~20 minutes) is considered highly secure for large amounts.
Common questions about this topic
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.
Ergo supports a full ecosystem: trade on Spectrum DEX, use SigmaUSD stablecoin, mix transactions with ErgoMixer, collect NFTs on SkyHarbor, mine with GPUs, lend/borrow on DuckPools, bridge to other chains via Rosen, and build dApps with ErgoScript. It's a complete platform for decentralized finance and applications.
This is not financial advice. Ergo has strong fundamentals: fair launch (no VC dump risk), innovative technology (eUTXO, Sigma Protocols, NiPoPoWs), active development, and a cypherpunk ethos. It's a smaller market cap project with higher risk/reward than established chains. Research thoroughly, understand the technology, and never invest more than you can afford to lose.
Ergo NFTs are native tokens with quantity of 1, making each unique. Unlike Ethereum where NFTs need smart contracts, Ergo NFTs are first-class protocol citizens. Mint for minimal fees (~0.001 ERG), trade on SkyHarbor marketplace, and enjoy full eUTXO security. NFTs can include rich metadata and royalties.
