Common questions about this topic
Building DeFi on Ergo starts with understanding the eUTXO model and ErgoScript. Unlike account-based chains, Ergo's box model provides deterministic execution, no MEV by design, and predictable gas costs. Use Oracle Pools for price feeds, and leverage existing patterns from Spectrum Finance and SigmaUSD.
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.
NiPoPoWs (Non-Interactive Proofs of Proof-of-Work) are cryptographic proofs that compress blockchain history. Instead of downloading gigabytes of blocks, light clients can verify the chain with just kilobytes of data. This enables true trustless light wallets, efficient cross-chain bridges, and sidechains - all without trusting third parties.
Rosen Bridge is Ergo's cross-chain bridge protocol for trustless asset transfers between blockchains. It connects Ergo with Cardano, Bitcoin (Runes), and Dogecoin. Unlike centralized bridges, Rosen uses a decentralized watcher network and multi-sig security. Bring assets to Ergo's DeFi ecosystem or move ERG to other chains.
