Glossary
20 terms
API
Application Programming Interface. A defined set of rules allowing software to communicate. Cerulea exposes REST APIs for external tools and workflows to interact with deployed systems.
WASM
WebAssembly. A binary instruction format enabling high-performance code execution in a sandboxed environment. Cerulea uses WASM as the runtime for smart contracts and modules.
EVM
Ethereum Virtual Machine. The execution environment used by Ethereum and compatible blockchains. Cerulea's Public L1 supports EVM compatibility, meaning Solidity contracts can run with minimal modification.
RPC
Remote Procedure Call. A protocol allowing external programs to request operations from a blockchain node. How wallets, applications, and backends submit transactions and query state.
PoS
Proof-of-Stake. A consensus mechanism where validators are selected based on staked collateral. Cerulea's Public L1 uses PoS for validator selection and network security.
Validator
A node in a blockchain network responsible for verifying transactions and adding new blocks. On Public L1, selected via PoS. On Private Chains, enterprise-selected.
Genesis Parameters
The initial configuration values that define how a blockchain network starts, including validator set, token distribution, and governance settings. Cerulea generates these automatically from Studio configuration.
Governance
The on-chain mechanism through which changes to a live blockchain system are proposed, voted on, and executed. In Cerulea, the only pathway for modifying a deployed system after launch.
Slashing
A penalty mechanism that reduces a validator's staked tokens for misbehavior such as double-signing or excessive downtime. Slashing conditions are configured during system setup.
Epoch
A fixed period after which validator sets are updated, rewards distributed, and governance checkpoints may occur. Epoch length is configured as part of the system's consensus parameters.
dApp
Decentralized Application. An application running on a blockchain rather than a centralized server, interacting with smart contracts without a single point of control.
IPFS
InterPlanetary File System. A peer-to-peer file storage protocol addressing files by content rather than location. Cerulea's storage integrations include IPFS-based providers for decentralized asset persistence.
Smart Contract
Self-executing code on a blockchain that enforces agreed-upon rules when predefined conditions are met. Cerulea provisions smart contract execution without requiring users to write contract code.
Oracle
A service providing verified real-world data to smart contracts, bridging on-chain logic and off-chain information such as price feeds or event data.
SLA
Service Level Agreement. A formal commitment defining expected service levels including uptime guarantees. For Private Chain deployments, the enterprise is responsible for maintaining SLAs on validator infrastructure.
Interoperability
The ability of different blockchain networks to communicate and transfer assets or data. Cerulea supports configurable cross-chain interoperability through message passing and asset bridging protocols.
No-Code
An approach enabling functional systems to be built through visual configuration rather than writing source code. Cerulea is fully no-code: every aspect of a blockchain deployment is configured, not programmed.
Blue-Green Deployment
An upgrade strategy where two identical environments run in parallel. Traffic shifts from old (blue) to new (green) at a precise moment, enabling near-zero downtime.
Canary Deployment
An upgrade strategy where a new version rolls out to a small subset of nodes first. If issues are detected, the rollout halts before broader impact occurs.
Data Sovereignty
The principle that data is subject to the laws and governance of the organization controlling it. Cerulea's Private Chain architecture is designed to preserve full enterprise data sovereignty.
