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.

ProximaX is developing a NEM-based platform with several on-chain and off-chain protocols. At its core, ProximaX is based on the NEM blockchain, and is designed to be an all-in-one platform for developing DApps. The platform has several parallel layers that are intended to provide decentralized storage, messaging, streaming, and content delivery services. The network is powered by the NEM-based XPX token. ProximaX intends on using a hybrid consensus mechanism for validating value transfers on these layers. Consensus will be driven with a combination of Proof-of-Importance (PoI), Proof-of-Storage (PoSt), and Proof-of-Bandwidth (PoB).

Aeternity is a smart contract driven blockchain platform that aims to integrate real world data and improve the overall performance of smart contracts. Aeternity has a hybrid consensus algorithm that combines PoW for verifying transactions, and PoS for governance purposes. The platform is based on a system of state channels that allow users to interact privately with each other and record this information off-chain.
