# Transaction Speed and Scalability
- #Sui: Processes up to 120,000 transactions per second (TPS) with a transaction finality of 390 milliseconds. Its unique object-based model and parallel processing enable high scalability.
- #Sol:Handles up to 65,000 TPS with a transaction finality of 2-12 seconds. Its Proof-of-History (PoH) consensus mechanism and sharding technique, Firedancer, aim to increase scalability.
# Consensus Mechanism
- Sui: Utilizes a Delegated Proof-of-Stake (DPoS) consensus mechanism with dual consensus protocols, Narwhal and Bullshark, for parallel execution and improved scalability.
- Solana: Employs a Proof-of-Stake (PoS) consensus mechanism with PoH, allowing for fast transaction processing and low fees.
# Ecosystem and Adoption
- Sui: Has a smaller ecosystem with around 90 DApps and 1 million active wallets. It's focused on Asian markets and Web3 gaming.
- Solana: Boasts a larger ecosystem with over 334 DApps and 5 million active wallets. It's focused on US markets, payments, DeFi, and institutional use cases.
# Development and Funding
- Sui: Developed by Mysten Labs, founded by ex-Facebook developers, with $336 million in funding.
- Solana: Developed by Solana Labs, founded by Anatoly Yakovenko, with $314 million in funding.
