Fantom is developing a smart contract platform based on a directed acyclic graph (DAG). They hope to address the scalability issues of current decentralized platforms. Instead of a blockchain, Fantom's Lachesis Protocol uses a directed acyclic graph to confirm transactions asynchronously. This transaction history is immutable and cannot be modified. The platform's Opera Chain will consist of three layers: an application Layer, Opera Ware Layer, and Opera Core Layer. Fanotm issued an Ethereum-based token in 2018.

GoChain is building a blockchain focused on speed and scalability. GoChain's protocol uses a Proof-of-Reputation (PoR) consensus mechanism and will be powered by the GO coin. They hope to significantly improve transaction times and reduce fee with an architecture that will rely on nodes managed by large enterprises. Their marketing materials places a strong emphasis on energy efficiency and reducing the monopolizing influence of large mining operations that have reduced the decentralization of other networks.

ChainLink is developing the LINK Network, which will enable connected smart contracts. LINK will provide smart contracts with a variety of external data and access to APIs. ChainLink's goal is to solve the connectivity problem that plagues smart contract based systems, and discourages mass adoption. Many decentralized applications are unable to connect with important external data sources due to limitations involving their consensus protocols. The LINK network wants to connect their smart contracts with external systems and APIs by using secure middleware.
