proof-of-stake cryptos?
So might be hard to explain, but when they add more chains, you add to the number of TPS that the network can handle, but it doesn't require any more hashpower. With this scalability, the actual energy per transaction is actually very small. Which is how these things should be measured.
There's a site that compares Kadena with others and it performs very well against other PoW coins, and compares favourably with PoS chains.
Due to this, isn't it so that we need to compromise on security?
I don't believe so, you'd still need 51% of the hashpower... if this doesn't change then I don't think it would.

I think there was initially a belief that you could take over one of kadena's chains with 5.1% of the hashpower, and if you have more and more chains, this number decreases. However, each chain is secured (currently) by 3 other chains, and those chains in turn are each secured by 3 others. So this doesn't work out. You'd still need 51% of the network. But the network is designed to be more cost effective to mine than attack. So would see extremely unlikely.
