FAQs

What is Chromia and how does it work?

Chromia is a Layer-1 relational blockchain platform that uniquely integrates relational databases with blockchain technology. This allows for structured data storage in linked tables, a significant improvement over traditional list-based blockchains. The platform enables direct on-chain data querying, high-throughput transactions, and real-time data indexing. Its modular design supports dedicated application chains ("one chain per dapp"), offering customized fee structures where dApps can cover costs, providing a gas-free experience for end-users, and empowering the overall Chromia Ecosystem.

What problems does Chromia solve in Web3?

Chromia addresses the challenges of complex data management and scalability in Web3. Traditional blockchains struggle with storing and querying intricate data sets, leading to reliance on centralized solutions. Chromia's relational blockchain fixes this by making data natively queryable and indexable on-chain. It also aims to decentralize AI infrastructure by supporting on-chain vector databases and distributed AI inference, providing a transparent and secure environment for AI agents and applications, and enhancing the capabilities of smart contract platforms.

What are the main use cases for Chromia (chr)?

Chromia excels in use cases requiring advanced data handling, particularly in Artificial Intelligence (AI) and Gaming (GameFi). For AI, it facilitates on-chain vector databases, AI inference, and decentralized AI agents, providing a robust foundation for blockchain-powered AI. In Gaming, it enables complex on-chain game logic, enhanced NFTs, and flexible fee models, often eliminating gas fees for players. Additionally, Chromia serves as a powerful decentralized data layer for various dApps and enhances existing Ethereum Ecosystem projects, with the chr token being integral to its vibrant ecosystem.

How does Chromia's relational architecture improve scalability compared to monolithic blockchains?

Chromia enables horizontal scaling by allowing each dapp to run on its own subchain with dedicated resources. Unlike monolithic chains (e.g., Ethereum), this isolates traffic so high activity on one dapp doesn't congest the entire network. Subchains process transactions in parallel and anchor data to system chains, achieving throughput that scales linearly with added subchains. This contrasts with Layer-2 solutions like rollups, which still depend on base-layer limitations.

What security measures protect Chromia's token bridge against validator exploits?

Chromia's bridge employs a multi-layered security approach: 1) Time-delayed withdrawals with administrator review periods to flag suspicious transactions; 2) Slashing mechanisms that penalize malicious validators by seizing staked CHR; 3) Ongoing audits by firms like Quantstamp to patch vulnerabilities (e.g., preventing duplicate withdrawals during mass exits). Validators must maintain active stakes to participate, disincentivizing exit-scam attacks.

How does Rell's design benefit developers compared to Solidity?

Rell reduces development complexity through: 1) Type-safe compilation to SQL, eliminating reentrancy and overflow vulnerabilities common in Solidity; 2) 7x more concise syntax for data definitions with meta-programming templates; 3) Native relational queries enabling complex on-chain data operations without external indexing. This allows developers to build data-intensive dapps (e.g., gaming inventories) with fewer lines of code and integrated security checks.

Can Chromia support Ethereum-native dapps without full migration?

Yes, via Chromia's Ethereum Interoperability Framework (EIF). Developers can deploy Ethereum-compatible dapps as Layer-2 solutions on Chromia subchains while maintaining: 1) ERC-20 token compatibility through the Chromia Token Bridge; 2) Gas-free user interactions funded by developer hosting fees; 3) Real-time EVM state ingestion (Q3 2025 roadmap) for synchronized data access. This hybrid model allows projects to leverage Chromia's scalability while retaining Ethereum ecosystem integration.

What distinguishes Chromia's hosting model from traditional gas fee structures?

Chromia replaces volatile gas fees with predictable hosting fees: 1) Developers pay fixed monthly CHR based on resource allocation (CPU/memory/storage), similar to cloud services; 2) Users experience zero transaction costs for basic interactions, lowering adoption barriers; 3) Developers design custom revenue models (subscriptions, in-app purchases) without gas constraints. This enables freemium models impossible on gas-dependent chains and shifts operational costs from users to dapp operators.
