What Is the Solana Gulf Stream? How It Differs From Traditional Mempool Architectures
- The mempool acts as a temporary storage area for unconfirmed transactions, allowing validators to process and confirm transactions based on gas fees.
- Solana, a high-performance blockchain, operates without a mempool, using the Solana Gulf Stream that forwards transaction messages to set validators.
- Solana's Gulf Stream ensures a network throughput of 65,000 can manage a 130,000 mempool, allowing for over 4,000 to 4,500 transactions per second.
- The Gulf Stream system in Solana requires transactions to include a recent blockhash, guaranteeing nonprocessed transactions do not linger.
- Solana's introduction of QUIC protocol improved communication between nodes, addressing challenges like data reliability during disruptions.
- Quic enables reliable data transmission with congestion control, session and flow control, enhancing Solana's network stability and resilience.
- Stake-weighted QoS on Solana prioritizes transaction packets based on validators' stakes, enhancing Sybil attack resistance and network performance.
- Solana and Ethereum differ in mempool architecture, with Solana pushing pending transactions to the leader and Ethereum dispersing transactions via gossip protocol.
- Ethereum relies on gas fees for transaction priority, while Solana has fixed base fees and the option for priority fees for faster execution.
- Solana's continuous block production differs from Ethereum's block intervals, impacting the processing of transactions and the occurrence of priority fees.
