Starknet launches development tool SN Stack

Ethereum Layer 2 project Starknet launched the development tool SN Stack to support developers in creating independent application chains (Appchain). SN Stack includes Starknet OS (blockchain operating system), CairoVM (smart contract execution), Blockifier (block building), and cryptographic proof and verification tools. SN Stack provides three different versions to meet different development needs: Madara, which provides a flexible open source modular framework; Dojo, a platform optimized for games and advanced on-chain applications; StarkWare Sequencer, which provides Starknet's entire infrastructure for dapps that require high performance.
