Hewlett Packard's blockchain as a service platform, called Mission Critical Distributed Ledger Technology (DLT), allows its customers to run distributed ledger processes on an enterprise platform. HP developed this solution in conjunction with R3, and is now offering it as a BaaS option to their enterprise customers.

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.
