what's Casper Network?

Casper Network is a Proof-of-Stake Layer-1 blockchain optimized for security, decentralization, and scalability, solving the blockchain trilemma. Launched in 2021, it supports tokenized real-world assets with upgradable smart contracts, protocol-level access control, and native parallel execution of multiple virtual machines (VMs) like WASM, eliminating the need for rollups or Layer-2 solutions for diverse applications. The network employs Zug Consensus, a deterministic protocol delivering instant finality essential for financial transactions, regulated assets, and enterprise workflows. Developer-friendly with Rust and WebAssembly support, plus SDKs in JavaScript and other languages, it emphasizes energy efficiency, on-chain governance, and seamless integration into enterprise IT architectures.

Casper Network mainnet upgraded to v2.2.0 on March 23, 2026.
