Just read last week's update which contains lot of interesting things like communication with external API's and smart contract execution, and active nodes recognition. It is really hard to say what you liked the most as everything is same important. INS's price are looking good at the same time as markets are overall looking good. A journey towards independence having own chain will make it highly desirable project.
Are they looking to switch over to the own chain? Ethereum is not ready for mass adoption and I would not be surprised if projects want to switch. However, i do not believe that INS actually need high TPS throughput. Maybe a bit higher than current Ethereum network, but not much higher. I believe that layer 1 on Ethereum will be enough for them. Don't you think so?
If I'm not mistaken I've heard they will have their own blockchain and will switch from ethereum to their own blockchain.
