It is only an issue in the first place because of bitcoin's purposely meniscule throughput. Monero's throughput adapts while bitcoin cash has 32x the max blocksize.
Algorand looks like a promising proof of stake altcoin in my opinion.
I agree, and I can't believe more people haven't mentioned it here. I am not going to rehash what anyone can read at the linked site, but it seems like an absolutely great project, and seems to be flying under everyone's radar.
If you said 2+2=4 and I said I don't agree, that doesn't change reality
Basically all (hardly even an exaggeration!) other cryptocurrencies are attempting to improve upon the throughput issue. Solana is a particularly prominent one with 50k/s
I'm interested in how all these other chains deal with people writing tons of junk transactions per second to bloat up the chain.
Having a transaction fee de-incentivizes most people who want to do this
Every junk transaction costs them money
From what I’ve seen they don’t
NANO actually just went through a pretty big spam attack and it crippled the network for awhile, but they supposedly came up with a pretty novel solution in the latest version. I haven't dug into it yet though. But NANO is fee-less, so it is (was?) more prone to these types of attacks. Having a fee increases the cost of a spam attack.
I don't know about other chains, but for ethereum you get money for destroying/freeing up block space. This is how the Chi gas tokens work: they write 0s to the chain when gas is cheap and destroy the blocks when gas is expensive.
I looked into it and Solana requires "Validator" nodes to be specially blessed by them to get rewards for running their software, so this isn't particularly de-centralized.
