Solana vs Starknet

Solana combines Proof‑of‑History, Turbine block propagation and Gulf Stream forwarding to achieve throughput exceeding 50 000 TPS with 400 ms block times. The 2024 Firedancer client written in C++ reduced validator CPU requirements and added parallel pipeline execution. Solana Pay and the Saga phone SDK illustrate the project’s push toward consumer‑grade web3 applications.

Starknet is a STARK‑based validity rollup where smart contracts are written in Cairo and executed off‑chain, with succinct proofs verified on Ethereum. The 2024 Madara sequencer supports parallel execution, and the ‘Quantum Leap’ upgrade reduced L1 calldata by 30 %. STRK token launched in February 2025, enabling slot auctions for sequencer decentralization roadmap.
