Finality is sub-second. Max TPS is hard to say, but it's scalable. Currently, it's probably in the 100s per sec.
How does it prevents spam ?
It's basically a prioritization system. Here's one relevant link to how it works: https://forum.nano.org/t/election-scheduler-and-prioritization-revamp/1837
So it prioritizes accounts that are not spamming the network
I'm not sure how their implementation will handle against a massive coordinated attack, but it's been working perfectly for me and my customers. It's consistently been the fastest and most responsive transacting crypto, imo
Thinking about the difference with HTR: they use pow for transactions to prevent spam and are also feeless and instant. Wondering how nano is safer and better to use
That's the other crypto I was excited about using. But, ultimately, it doesn't provide any advantage on the transacting aspects of nano. However, for other use-cases, I guess Hathor would work too, and both could co-exist? But from a transactional point of view, nano is basically close to the ideal. Adding in pow aspect, nano smart-contracts, etc. Would be a compromise on the original idea for more use-case that is not the focus of a transacting crypto.
It prioritizes incoming transactions based on amount of nano and last transaction time. So if there is an overflow of transactions, the low amount spam hitting every second will be just discarded. This approach actually prevented the last spam attack happened last spring. Nano devs also implemented some extra options which allow every node owner set parameters in order to quickly react to any future spam issues. As I know the wallet creation uses POW to prevent such spam as well. Think of emails. You can send email to everyone for free and you are not bothered with spam too much. Moreover the v23 optimization increases the transaction throughput dramatically, so such spam atack will go through the nodes without any hassle.
So I'll just have to send more than what is considered low ammount to spam the network? What's the throughput that's able to deal with spam without even noticing it
I have a question. Why would anyone choose to be paid in nano or any other crypto if it's volatile? Isn't a stable coin with feeless and speedy transactions even more interesting than this?
If I paid people in any other crypto, there would be more overhead and eventual losses due to accumulation of fees. A stable coin that's feeless and fast doesn't exist. In fact, you're basically describing nano if it were backed and pegged to an underlying asset.
Not just amount is considered. The time between the current and the last transaction plays a big role too.
How come? What is the parameter here?
