"Ardor is an evolution of the Nxt software that addresses issues of blockchain bloat, scalability and versatility. Ardor is being designed as a complete ecosystem where multiple players can interact with each other without needing to go outside the platform. Ardor solves the problem of having to store and process large amounts of non-essential long term data in the blockchain, by separating the tokens providing blockchain security from those used for regular transactions."
What we don't like:
To be a successful platform, you need companies running child chains on your network. Ardor has some interesting features. However it’s difficult to see a migration from Ethereum. Ardor may pick up a niche market such as messaging platforms based on the blockchain.
What we like:
Ardor is an evolution of the Nxt blockchain platform. Nxt came out in 2014 since then blockchain technology has improved drastically. It’s wise for the Nxt team, the company Jelurida, to continue to upgrade their product as new tech emerges. A unique features on the Ardor platform is gas being paid in the child chain currency. The forging process on the Nxt chain is also unique. The more tokens you hold the more you receive from forging.
