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.

EvenCoin is a self-mining smart contract platform that is built on the Ethereum blockchain. EvenCoin is mined in parallel to even numbers of Ethereum blocks. The team behind EvenCoin are developing several decentralized projects that will use the self-mining protocol, including an exchange and a travel booking platform.

Ternio is developing a scalable blockchain framework called Lexicon. It was originally a fork of Hyperledger Fabric, and is designed to handle the high transactions rates that enterprise business clients need. Ternio's framework uses its Lexicon Blockchain as a data protocol, and the Stellar Blockchain as a payment protocol. Ternio will have a Byzantine Fault Tolerance (BFT) consensus mechanism. Ternio's marketing materials mention the benefits that their high performance, Lexicon blockchain can have in programmatic digital advertising, as well as a variety of other industries. Ternio also created the BlockCard; a crypto debit card that enables users to spend their cryptocurrency. Their network is currently powered by the Stellar-based TERN token.
