Metaverse is a blockchain platform that is being developed by the Chinese company ViewFin. Metaverse has a very ambitious scope and aims to combine a variety of blockchain functionalities in one comprehensive Blockchain-As-A-Service platform. They aim to build a smart contracts platform, similar to Ethereum or NEO, that will also enable users to register their digital identities and integrate real-world data.
Metaverse has three types of ledgers: asset ledgers, identity ledgers, and data feed ledgers. The platform can be used as an intermediary with real world data and also has a decentralized exchange where assets can be traded.
Metaverse is powered by the ETP token.

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.

Stratis provides a user friendly solution for developing a blockchain application. One of it's advantages is that it doesn't require learning a new coding language. It uses C# on the .Net framework. Stratis has become a popular platform for blockchain developers. The Cloud Stratis platform allows clients to deploy their dAPPS without having to maintain the network. It can create blockchain nodes for several blockchain, such as: Bitcoin, Ethereum, and Bitshares. The Stratis coin is the unit of currency on the Stratis blockchain, which has a Proof-of-Stake consensus mechanism.
