Proof of History (PoH)
The Solana network uses a PoH consensus. Using PoH allows the Solana network to create a historical record that proves an event has occurred at a specific moment in time. PoH uses a cryptographically secure function written so that output cannot be predicted from the input, and must be properly executed to generate the output.
Better Transaction Speeds
In reality, Solana is taking advantage of Ethereum’s slower network. Solana achieves such efficient transaction speeds by utilizing a centralized network, which comes with a concerning level of risk for its users as mentioned above.
The Solana network uses a Tower Byzantine fault-tolerant (BFT), which removes the need for nodes to communicate with each other in real-time, and the result is improved efficiency. Currently, the Solana network can process approximately 50,000 transactions per second (TPS).
In addition to quicker transaction speeds, Solana is known for its enhanced scalability. The Solana network is scalable at its core level, meaning it does not require layer-two solutions to increase scalability.
The technology behind the Solana network breaks down data into smaller chunks, making it easy to transfer it across the network. Another technology called Sealevel also helps the processing of transactions across GPUs and SSDs, both of these combined result in an efficient blockchain network.
