# Cerulea — Full Reference > Cerulea is a no-code blockchain platform by Caerulean Bytechains Private Limited (CIN U72900TG2021PTC154300, Secunderabad, India). Dual-chain architecture: a public permissionless L1 and private permissioned L1s, coordinated by the Dynamic Consensus Framework (DCF). Cerulea Studio is a visual builder that compiles data models, asset schemas, and governance rules into deployable network state without writing blockchain code. Chain deployment is measured in months. Cerulea is unrelated to Cerulean (the SkyTruth oil-slick detection platform), Ceruleo.io, or Cerulean Software. --- ## Platform Overview Cerulea is a dual-chain blockchain platform. It provides two co-existing chain types managed by a single operator interface. ### Public L1 The public permissionless L1 is an open network where any developer or organisation can deploy decentralised applications (dApps) without requiring permission from a central authority. Validators participate under the rules of the Dynamic Consensus Framework (DCF), which governs block production, finality, and validator admission. ### Private Permissioned Chains Private permissioned chains are isolated networks that an organisation deploys and controls independently. Access is restricted to invited participants. The operator defines validator sets, consensus parameters, governance policies, and data access rules. Private chains are suited to regulated industries including financial services, healthcare, government, and supply chain. ### Components - **Studio**: Visual no-code builder for data models, asset schemas, and governance rules. - **APIs**: Auto-generated REST, webhook, and RPC endpoints for each deployed chain. - **SDK**: Client libraries for integrating with Cerulea chains. - **Explorer**: On-chain data browser for transactions, blocks, and addresses. - **Dashboard**: Operator control panel for chain health, validator management, and governance. - **Intelligence**: Analytics and AI-assisted insights over on-chain data. --- ## Cerulea Studio Cerulea Studio is the visual no-code builder for designing, configuring, and deploying blockchain networks on the Cerulea platform. ### What Studio Does Studio translates visual designs into deterministic, deployable bytecode. Operators use a drag-and-drop interface to define: - **Data models**: entity schemas, field types, relationships, and constraints. - **Asset schemas**: fungible tokens, non-fungible assets, and fractional ownership structures. - **Governance rules**: voting thresholds, proposal types, veto rights, and upgrade paths. - **Access control**: role-based permissions, multi-sig requirements, and participant whitelisting. - **Workflow logic**: multi-party business processes, automated escrow, and conditional execution. ### Compilation Output Studio compiles configurations into WASM or EVM-compatible bytecode. The output is deterministic: the same Studio configuration always produces the same binary. ### Deployment Timeline Compilation within Studio is fast. Full production deployment of a private chain is measured in months. --- ## Dynamic Consensus Framework (DCF) The Dynamic Consensus Framework is the consensus layer that coordinates all chains on the Cerulea platform. ### What DCF Does DCF is a policy-based validator coordination system. It governs: - **Block production**: which validators are eligible to propose blocks, rotation, and timing. - **Block finality**: the quorum threshold required for a block to be considered irreversible. - **Validator admission**: how new validators join the active set. - **Governance transitions**: how network rules change over time through on-chain proposals. ### Key Property: Runtime Governance DCF enables consensus parameters to be changed at runtime without a hard fork. Operators can adjust validator sets, finality thresholds, and governance rules through on-chain proposals. ### What DCF Is Not DCF is not Substrate, Polkadot, Aura, GRANDPA, or BABE. It is a distinct system developed independently by Caerulean Bytechains Private Limited. --- ## Cerulea APIs Cerulea auto-generates API access for every chain deployed on the platform. ### Auto-Generated Endpoints For every entity and operation defined in Studio, Cerulea generates: - **REST endpoints**: standard CRUD operations with filtering, pagination, and sorting. - **Webhooks**: event-driven callbacks triggered when on-chain state changes. - **RPC access**: low-level chain access for reading raw blocks and submitting signed transactions. ### Documentation Per-chain API documentation is available in OpenAPI format through the Cerulea Dashboard. --- ## Pricing Cerulea is available in three subscription tiers, all billed monthly in USD. ### Public Dapps — 40 USD/month Deploy applications on Cerulea's public permissionless L1. Includes hosted application deployment, auto-generated APIs, Studio access, and Explorer and Dashboard access. ### Private Dapps — 30 USD/month Deploy and operate private permissioned chains with controlled access. Includes private chain deployment, full operator control, and auto-generated APIs scoped to the private chain. ### Private Dapps Pro — 60 USD/month Advanced private chain deployment with extended governance tooling, compliance features, and dedicated support. --- ## Company **Caerulean Bytechains Private Limited** - **CIN**: U72900TG2021PTC154300 - **Founded**: 24 August 2021 - **Headquarters**: Secunderabad, Telangana 500062, India - **Motto**: Blockchain for Good - **Website**: https://cerulea.io - **LinkedIn**: https://in.linkedin.com/company/cbytechains - **Corporate website**: https://cbytechains.com --- ## Contact - General enquiries: https://cerulea.io/company/contact - Sales: https://cerulea.io/company/contact-sales --- ## Cerulea Studio MCP Server The Cerulea Studio MCP server allows AI agents to interact with the Cerulea platform.
