Multi-Layered Architecture

PreviousDesignNextThree Main Sets of Participants

FNCY blockchain provides the scalability and reuse of existing modules through a multi-layered architecture, and makes it easy to modify existing contracts using a smart contract architecture.

Multi-layered architecture consists of infrastructure, client interface execution engines, network protocols, and storage.

FNCY chain consists of the following layers :

  • API and Tooling: FNCY chain enriches the blockchain ecosystem by providing powerful and complete APIs and tools.

    • FNCY Scan: Provides real-time FNCY blockchain data and analysis of blocks, transactions, contracts, and accounts.

    • Governance/Staking App: Provides the ability for validators to easily propose, vote, and delegate.

    • APIs : Provides immediate and reliable NFT and Defi valuable information through RPC and Websocket.

  • Client Interface: Provides Web3 JSON-RPC with 100% compatibility with Ethereum network.

  • Governance Modules: Provides chain governance such as staking and slashing.

  • Execution Runtime: 100% EVM compatibility and smooth migration of existing Smart Contracts.

  • Consensus: The consensus method of FNCY chain is defined as Proof-of-Stake-Authority (POSA). The PoSA consensus algorithm is a hybrid mechanism between a Proof-of-Staking (PoS) consensus mechanism and a Proof-of-Authority (PoA) consensus mechanism.

  • Network Protocol: A protocol for P2P communication between a validator and node.

  • Storage & State: Provides key-value storage and Merkle Tree State, Tx & Block storage optimized for high capacity processing.
