Solana vs Stellar

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.

Stellar is a payments‑focused blockchain that uses the Stellar Consensus Protocol (SCP), a federated Byzantine agreement where each node chooses its own quorum slices. Anchors issue fiat‑backed tokens, and Stellar’s built‑in DEX offers path payments that can hop through multiple assets in a single transaction. The 2023 Soroban upgrade added WebAssembly smart contracts, enabling on‑chain AMMs, lending and other DeFi primitives.
