Nano is finally delivering confirmation under a second again after fully rolled out v21.3 to be spam-tolerant.

Dealing with spam in decentralized network, while maintaining almost instant confirmation and feeless is very, very difficult.

Some says one of these factors gotta give, all three can't exist the same time.

It has to be at least on of these: centralized, slow or fees.

It helps me get a better understanding of spams in a decentralized network that spams will always exist. You can't equate spams the way like you do with a centralized system like emails. Emails can eradicate spams, if the email providers can't, that's more about the provider lacked of ability. In a decentralized world, you will have spam as long as you feeless. Nano just working to be a spam-tolerant but not spam-resistant. Tolerant of it so it doesn't affect the rest of network for legit transaction.

I have a very small bag of Nano. But their goal is truly admirable. It's hard and might not work. But I want a crypto that tries to solve it, not in a sandbox environment but in a actual real world mainnet.
