What technology stack does Solana software use?
Solana's highly efficient blockchain is made up of five fundamental breakthroughs: A Clock Before Consensus: Proof of History Nodes in a distributed network cannot trust the timestamp on messages received from other nodes, making it difficult to agree on the order in which events occur in a distributed network. By establishing a cryptographically safe source of time, Proof of History (PoH) is used to overcome this issue. It is a high-frequency Verifiable Delay Function (VDF) that takes a certain number of steps to evaluate yet provides a unique result that is publicly verifiable and can be verified. Nodes can generate the next block without aligning themselves with the entire network because they can trust the date and sequence of messages they've received. Consensus costs are reduced as a result of this. Turbine: A Protocol for Block Propagation A separate but linked protocol, Turbine, is used by Solana to transmit blocks (share blocks between validators)....
