What is
ErgoScript?
ErgoScript — язык смарт‑контрактов Ergo, задающий условия расходования боксов в eUTXO‑модели и поддерживающий встроенные криптопримитивы.
ErgoScript описывает условия, при которых бокс может быть потрачен. Контракты проверяются узлами при валидации транзакции и часто строятся вокруг проверки структуры входов/выходов и данных в регистрах. Встроенные криптографические примитивы (включая Sigma‑протоколы) позволяют создавать сильные условия, включая приватные сценарии.
Key Points
- Условия расходования боксов (eUTXO)
- Проверка контекста транзакции и данных в регистрах
- Встроенные криптографические примитивы
- Хорошо подходит для детерминированных финансовых протоколов
Use Cases
1
DEX, пулы ликвидности и свопы
2
Алгоритмические стейблкоины и кредитные протоколы
3
Приватные условия на Sigma‑протоколах
4
Мультисиг и сложные правила расходования
Technical Details
ErgoScript compiles to ErgoTree, a typed abstract syntax tree evaluated by nodes. Key constructs include: `SELF` (current box), `INPUTS`/`OUTPUTS` (transaction boxes), `CONTEXT` (block info), and Sigma propositions (`proveDlog`, `proveDHTuple`). Scripts return Boolean or SigmaProp values.

Frequently Asked Questions
Questions about ErgoScript
Common questions about this topic
What is ErgoScript and how does it work?
ErgoScript is Ergo's smart contract language - a Scala-based, functional language that compiles to ErgoTree for on-chain execution. Unlike Solidity, ErgoScript is not Turing-complete by design, ensuring predictable execution costs and easier formal verification. It's powerful enough for complex DeFi yet safe enough to audit.

Technology
Is Ergo a good investment?
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.

What can I do with Ergo?
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.

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.
