Achain is creating a Blockchain-As-A-Service platform for DApp development. It is designed to make it easier for companies to create smart contract powered DApps. Achain has a delegated Proof-of-Stake (dPoS) consensus mechanism and is powered by the ACT coin. One of Achain's main advantages is that is easy to fork. Users can create an independent chain that can be customized. These independent chains can communicate with the main Achain platform with a value exchange protocol that connects them.

Ardor is a blockchain development platform that was created by Jelurida. The Ardor blockchain operates as a Blockchain-as-a-Service solution that can be implemented with minimal programming knowledge. Ardor's unique architecture separates the blockchain into parent and child blockchains. The parent blockchain only stores information that is directly related to maintaining the consensus of the overall network, with a Proof-of-Stake (PoS) mechanism. All other details related to smart contracts, including applications, governance mechanisms, and asset exchange, are stored on the child chains. This significantly limits the overall blockchain size, and also allows child chains to be used for specific purposes.
