The Solana blockchain uses an innovative Proof of History mechanism to confirm transactions that are recorded on the network. Solana is designed to separate the consensus process from the flow of transactions. This is done with a recursive, verifiable delay function that hashes incoming transactions, and recording information as a function of time. Every node on the Solana blockchain is assigned a cryptographic clock that enables the network to determine the time and ordering of transactions, without having to wait for consensus from other nodes. By separating the process of transaction verification from their recording, a higher throughput is achieved without sacrificing network security.

Hydrogen is a fintech company that develops API' for creating financial applications. They are developing the open-source Hydro blockchain platform that emphasizes identity management and security. The network is powered by the Ethereum-based HYDRO token.

HYCON is a blockchain platform powered by the Hyperconnected Coin. The decentralized platform has a Directed Acyclic Graph (DAG) architecture, and is focused on improving scalability and throughput. HYCON's SPECTRE consensus algorithm is designed to enable horizontal scalability, where several blocks can be added at the same time.
