Elrond - 36,000 TPS on 16 shards - comment from admin in their official Telegram group dated by 4th of July 2019
Matic - 6,000 - 10,000 TPS in closed environment, and a single sidechain is theoretically capable of up to 65K TPS - comment from admin in their official Telegram group dated by 1st of July 2019
Zilliqa - 2,828 TPS on testnets, with shards, 2400 nodes - comment from admin in their official Telegram group dated by 4th of July 2019
EOS - centralized, but 9,179 TPS according to this article dated by 05.12.2018: https://medium.com/@cryptolions/new-maximum-eosio-tps-demonstrated-in-jungle-testnet-9179-15a485f2e79
Radix - 1,417,786 TPS (https://twitter.com/radixdlt/status/1146423706958344194) on ~1200 nodes spread across the world.
Good statistics collected,,, but I am now thinking, if only there was a rating site that tested out all of these networks and blockchains to see if TPS was really true. I agree, speed is not everything but it is something. It will not be a problem for a long time anymore after Bitcoin gets the Lightning Network to be adopted too.
Should mention Waves as well right?
Exactly. These tests have to be:
1) verifiable
2) non-laboratory (nodes have to be located on different continents)
3) with full signature verification (not like other projects usually do: Hashgraph didn't verify signatures, for instance - that's written in their whitepaper)
4) transaction size should be the same as it will be on main net - definitely more than >100 bytes.
Radix achieves all:
1) this test is verifiable (you can repeat it: https://www.radixdlt.com/post/test-method-part2/), it was replayed many times already and every time you could see ~1M tps. Also these tests are done using Bitcoin transactions database, so everyone can check any Bitcoin address during a test.
2) it was done on >1000 nodes in 17 cities around the world - decentralized.
3) it did full signature verification
4) average transactions size = 1 KByte
Speed/scalability is not just "something", it's a real issue with current blockchains/DAGs. You can't and you won't have mass adoption until this problem is solved. You need billions of people/devices to work simultaneously. If you want WeChat, WhatsApp, payment rails (like VISA, Alipay etc.), IoT devices to work all on top of the same ledger, it needs to be really scalable, without bottlenecks, permissionless and secure. Something which solves the Scalability trilemma. That is Radix.
Lignting Network will help Bitcoin a little, but its blockchain will still be a bottleneck. Think about it youself - when millions of people will open/close channels in LN, everytime there will be a record/transaction to the blockchain, which can't settle more than 7 txs per second. So it will work only until it hits a limit.
Ideally transactions need to be done on-chain. You simply don't need 2nd layer solutions if you have scalable tech.
Waves doesn't solve a scalability problem.
