| 1 | +# Tari Layer 2 (Ootle) - Frequently Asked Questions |
| 2 | + |
| 3 | +## General Questions |
| 4 | + |
| 5 | +### What is Tari? |
| 6 | +Tari is a blockchain platform designed specifically for digital assets like NFTs, loyalty points, in-game items, and credit card rewards. It's built to be scalable, secure, and easy to use. |
| 7 | + |
| 8 | +### What is Layer 2 (Ootle)? |
| 9 | +Layer 2, also called "Ootle," is Tari's smart contract platform where developers can build and deploy applications. It's where the magic happens - NFTs, tokens, games, and other digital asset applications run here. |
| 10 | + |
| 11 | +### What's the difference between Layer 1 and Layer 2? |
| 12 | +- **Layer 1 (Minotari)**: The base blockchain that provides security through mining. Uses XTM as currency. |
| 13 | +- **Layer 2 (Ootle)**: The smart contract layer where applications run. Uses XTR as currency for transactions. |
| 14 | + |
| 15 | +### What can I build on Tari Layer 2? |
| 16 | +You can build: |
| 17 | +- NFT collections and marketplaces |
| 18 | +- Custom tokens (fungible and non-fungible) |
| 19 | +- Gaming applications with in-game items |
| 20 | +- Digital collectibles |
| 21 | +- Loyalty and rewards programs |
| 22 | +- DeFi applications (exchanges, liquidity pools, lending) |
| 23 | +- Any application involving digital assets |
| 24 | + |
| 25 | +## Currency & Transactions |
| 26 | + |
| 27 | +### What currency does Layer 2 use? |
| 28 | +Layer 2 uses **XTR** (pronounced "X-T-R") as its native currency for paying transaction fees and interacting with smart contracts. |
| 29 | + |
| 30 | +### How do I get XTR? |
| 31 | +- **For Testing**: You can get free testnet XTR from the faucet in your wallet |
| 32 | +- **For Production**: XTR will be available through exchanges and can be bridged from Layer 1 |
| 33 | + |
| 34 | +### Are transactions private? |
| 35 | +Yes! Tari offers strong privacy by default: |
| 36 | +- Transaction amounts are hidden |
| 37 | +- User identities are protected |
| 38 | +- Only the parties involved can see transaction details |
| 39 | + |
| 40 | +### How fast are transactions? |
| 41 | +Transactions on Layer 2 are fast, typically confirming within seconds. The network is designed for high throughput and low latency. |
| 42 | + |
| 43 | +## Wallets & Accounts |
| 44 | + |
| 45 | +### What wallets can I use? |
| 46 | +- **Tari Wallet Daemon**: The official wallet with a web interface |
| 47 | +- **Tari Console Wallet**: Command-line wallet for advanced users |
| 48 | +- Mobile and desktop wallets are in development |
| 49 | + |
| 50 | +### How do I create an account? |
| 51 | +When you set up the Tari Wallet Daemon, it automatically creates a default account called "dev" for you. You can create additional accounts as needed. |
| 52 | + |
| 53 | +### Can I have multiple accounts? |
| 54 | +Yes! You can create multiple accounts within your wallet for different purposes or to organize your assets. |
| 55 | + |
| 56 | +### What's a component address vs a template address? |
| 57 | +- **Template address**: Like a blueprint - the reusable code for an application |
| 58 | +- **Component address**: Like a house built from that blueprint - an actual instance of the application |
| 59 | + |
| 60 | +## Development & Testing |
| 61 | + |
| 62 | +### How do I test my application? |
| 63 | +Tari provides the **Igor Testnet**, a live testing environment where: |
| 64 | +- You get free testnet XTR from the faucet |
| 65 | +- You can deploy and test your applications safely |
| 66 | +- No real money is at risk |
| 67 | + |
| 68 | +### Do I need to know blockchain programming? |
| 69 | +While blockchain knowledge helps, Tari is designed to be developer-friendly: |
| 70 | +- Use familiar languages (Rust for smart contracts, JavaScript for frontends) |
| 71 | +- Good documentation and examples |
| 72 | +- Active community support |
| 73 | + |
| 74 | +### Is there a local development environment? |
| 75 | +Yes! You can run a complete local network on your computer using the Tari Swarm Daemon, which gives you: |
| 76 | +- Full control over your test environment |
| 77 | +- No need for internet connectivity |
| 78 | +- Instant resets and testing |
| 79 | + |
| 80 | +## Smart Contracts & Templates |
| 81 | + |
| 82 | +### What's a "template"? |
| 83 | +A template is Tari's term for a smart contract. It's reusable code that defines how a digital asset or application works. Think of it as a blueprint. |
| 84 | + |
| 85 | +### What programming language are templates written in? |
| 86 | +Templates are written in **Rust** and compiled to WebAssembly (WASM). This makes them fast, secure, and portable. |
| 87 | + |
| 88 | +### Can I use existing templates? |
| 89 | +Yes! Many common templates are available: |
| 90 | +- Basic NFT templates |
| 91 | +- Fungible token templates |
| 92 | +- DEX (exchange) templates |
| 93 | +- You can use these as-is or customize them |
| 94 | + |
| 95 | +### What's the difference between deploying and instantiating? |
| 96 | +- **Deploying**: Publishing the template (blueprint) to the blockchain |
| 97 | +- **Instantiating**: Creating an actual working instance from that template (building from the blueprint) |
| 98 | + |
| 99 | +## Network & Infrastructure |
| 100 | + |
| 101 | +### What network should I use? |
| 102 | +- **Igor Testnet**: For testing and development (free testnet XTR available) |
| 103 | +- **Mainnet**: Coming soon for production applications |
| 104 | +- **LocalNet**: Your personal local network for development |
| 105 | + |
| 106 | +### What's a validator node? |
| 107 | +Validator nodes are computers that process transactions and maintain the network. They work together in committees to ensure everything runs smoothly and securely. |
| 108 | + |
| 109 | +### What's an indexer? |
| 110 | +An indexer is a service that helps you search and query blockchain data. It makes it easy to find transactions, check balances, and look up information about assets. |
| 111 | + |
| 112 | +### Is the network decentralized? |
| 113 | +Yes! Tari Layer 2 uses a committee-based consensus system where multiple validator nodes work together. No single entity controls the network. |
| 114 | + |
| 115 | +## Resources & Tokens |
| 116 | + |
| 117 | +### What are resources? |
| 118 | +Resources are digital assets on Tari - things like tokens, NFTs, or any other valuable digital items. They can be fungible (like coins) or non-fungible (like unique collectibles). |
| 119 | + |
| 120 | +### What's a vault? |
| 121 | +A vault is like a secure container in your account that holds your resources (tokens, NFTs, etc.). Each account has vaults for different types of assets. |
| 122 | + |
| 123 | +### What's a badge? |
| 124 | +Badges are special tokens that grant permissions or access rights. For example, an admin badge might let you mint new tokens or update settings. |
| 125 | + |
| 126 | +### Can I create my own token? |
| 127 | +Absolutely! Creating custom tokens is easy with Tari. You can create: |
| 128 | +- Fungible tokens (like coins) |
| 129 | +- Non-fungible tokens (unique items) |
| 130 | +- Tokens with custom rules and properties |
| 131 | + |
| 132 | +## Security & Permissions |
| 133 | + |
| 134 | +### How are permissions handled? |
| 135 | +Tari uses a flexible access control system: |
| 136 | +- You can set rules for who can call which functions |
| 137 | +- Use badges to grant special privileges |
| 138 | +- Define custom permission logic for your application |
| 139 | + |
| 140 | +### Is my data safe? |
| 141 | +Yes! Tari is built with security in mind: |
| 142 | +- Cryptographic protection of all data |
| 143 | +- Privacy by default |
| 144 | +- Battle-tested cryptography (Ristretto points, Pedersen commitments) |
| 145 | + |
| 146 | +### Can smart contracts be upgraded? |
| 147 | +Templates themselves are immutable once deployed, but you can design them to be upgradeable by including update functions protected by appropriate permissions. |
| 148 | + |
