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 had no pre-mine, no ICO, no VC allocation. 100% of ERG comes from mining. This means no insiders dumping on you, no VCs controlling governance, no foundation with majority stake. Fair launch creates genuine decentralization - the network belongs to miners and users, not early investors seeking exit liquidity.
MEV (Maximal Extractable Value) is profit extracted by reordering, inserting, or censoring transactions - think front-running and sandwich attacks. Ergo's eUTXO model provides structural MEV resistance: transactions reference specific boxes (UTXOs), making reordering attacks much harder. There's no shared global state to exploit like in account-based chains.
SigmaUSD is Ergo's algorithmic stablecoin, pegged to USD and backed by ERG reserves. It uses the AgeUSD protocol: users mint SigUSD by depositing ERG, while SigRSV holders provide reserve backing and absorb volatility. The reserve ratio (400-800%) ensures stability. No centralized issuer, no bank accounts - pure crypto collateral.
