BIE Node

High-performance L1 blockchain node for the BIE Network, featuring a native DEX with perpetuals and spot trading.

Overview

BIE Node is the core blockchain infrastructure powering the BIE Network. Built in Rust for maximum performance and reliability, it implements:

• BFT Consensus: Byzantine Fault Tolerant consensus mechanism for finality
• Native DEX: Central Limit Order Book (CLOB) engine with sub-millisecond matching
• EVM Compatibility: Full Ethereum Virtual Machine support
• Perpetuals Trading: Native derivatives with up to 50x leverage
• Oracle Integration: On-chain price feeds for derivatives
