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.

Algorand is a Boston based company that is developing a blockchain network with a Pure Proof of Stake (PPoS) consensus mechanism. Algorand's decentralized platform is designed to enable faster transaction times and remove some of the technical barriers of creating scalable DApps. Algorand was founded by Silvio Micali, a pioneer in the field of cryptography.

Aergo is developing an SQL based smart contract platform that will allow developers to more easily share data and create DApps. Their platform will combine elements of public and private blockchain architectures and will have a hybrid BFT/dPoS consensus mechanism. The ERGO Hub will serve as a blockchain hosting service that will allow users to test and deploy their own blockchains. Their network is currently powered by the Etherem-based AERGO token.
