Highest average transactions per second at full blocks is what I'm looking for.

No vaporware.

Actual testnet results are preferable to theoretical estimates.

WBB - https://bitcointalk.org/index.php?topic=952619.0

can already hit 10k with ease, apparently double that is no issue.  allegedly more is possible depending on reliability.

rumor is 100k one day for them.

Any proof?
besides a locked Thread WBB??

That's a fantastic number, like x3 the Visa network at peak.

Yesterday there was an initial stresstest for IOTA, using 60 nodes distributed globally.
There were peaks of 110 confirmed transactions per second:

A larger stresstest is planned for today, the first one was only to make sure all data gathering scripts were working properly.
Note that most (all?) cryptos claiming huge amounts of TPS have never done a gobal stresstest with more than a handful nodes.

Well, most "scalable" projects are vaporware and it's just hype. For example segwit isn't scaling, just a tool that allows lightning network in the future (2-3-5years). The first project that will really "scale" above these jokes of 10-50-100tps is ethereum with raiden in bit over 1 month with raiden. It scales with the number of participants so at first it will only have thousands (tps) at most. But with more adoption and more participants it will be able to scale over 1mil tps.

@achimsmile 110 TPS is a joke for 2017 and above. Also, i assume that 110 is on chain right ?

On chain yes. But how come I haven't seen a single crypto achieving that on a public, globally distributed stresstest? Glad to be proven wrong.
In fact I agree with you, 110 really is not nearly enough, but as said, bigger stresstest today, I'll keep you updated.

Probably not vaporware (didn't find the sourcecode though?) , BUT this was a private stresstest on just two nodes, he'll have to actually prove that it scales on globally distributed nodes (latency, bad connections, package drop).
Centralized systems can acheive such an amount of tps quite easily, and two nodes doesn't really sound like decentralized to me.

i'd like to see some of these claims put to the test with actual extended usage. that's on top of being able to look at the code and actually being decentralised. many of them are likely to fall apart when battle tested or are talking bullshit.

there are at least a 100 topics on this subject which you can search for and find lists of alts after alts saying they have the highest speed of transactions.

but having faster transactions on its own is meaningless. instead you should ask
- how their network is doing? is there even nodes running by users (real decentralization) or is it a couple of nodes by a couple of services and mining pools.
- how is the orphan rate? and how is the risk of double spend!
- how is the hashrate distribution? is there any risk of different types of attacks.
- how big is their blockchain if you want to use their wallet, or run a full node at home. and how big is it going to be in a year, 2 or 8 years from now?

ask these questions and some more (that i can not remember right now) and you will end up concluding bitcoin is the only cryptocurrency with ability to handle TPS at whatever rate it currently is.

edit: a simple hint:
higher TPS > more transactions per second (each transaction takes space) > bigger blocks > blockchain size increasing at a much faster speed > storage problems
+
higher TPS > more number of transactions > more network traffic needed from nodes to propagate these transactions + more system resources needed to validate them
=
less running nodes, low network security and lots more in long run.

p.s. i'd genuinely love to see how any of these coins can handle a spam attack like bitcoin is experiencing.

All valid points, but I strongly disagree with your conclusion. It's been proven many times that Bitcoin can't handle enough TPS, there have been over 100k unconfirmed transactions recently, which is just not good enough.

Sadly all blockchains suffer from the limitation of transaction ordering. Off-chain is a solution, but will introduce new problems/complexity (trust, cost of opening payment channel etc.)

read my p.s. and that is a genuine interest of mine wanting to see how other altcoins can handle a spam attack as massive scale as bitcoin (100K tx) and as long as bitcoin (2-3 years).

and yeah, there is always going to be limitations and downsides in any system. nothing is perfect.

The solution seems to be to explore new ways of organizing decentralized ledgers, apart of using chains. Chains are serial, and Block 1 has to come before Block 2 (transaction ordering). It will always be a bottleneck. We have to parallelize the processing of transactions and get rid of transaction ordering to speed things up.

interesting, any examples i can check when i get some time?

Search for DAG (directed acyclic graph) and Tangle concepts.

ZEIT  20X  bitcoin's current Onchain Transaction Capacity.

Our price is extremely low until the ultra low inflation activates in the next month or so.

But you could probably buy $100 worth of ZEIT and have ~ same % of coins as the BTC spammers,

Feel free to hit ZEIT with a spam attack, take your best shot. :D

FYI:
Our Transaction fee is fixed and are all served in the order they appear in the mempool , none of that BTC shenanigans requiring higher fees.  ;)

FYI2:
No Limits on our Offchain Transaction Capacity,
reason being we will use multiple 3rd partys to do offchain , (No need for deadwit)
currently Cryptopia & NovaExchange you can send ZEIT offchain to another user on their exchanges,
it only comes back onchain when you withdraw from their exchanges.

todays EXP ... played with openledger ... aka BTS we can handle 1000s of TX/sec ... well it can't handle 1 market order ... maybe just f'bar UIX but still  none-functional, even for even a crypto nerd.

i have checked it out.
ZEIT  also has 2000X  bitcoin's current orphan rate.

the number of orphans created by ZEIT is about 1500 to 2000 blocks per day.

when price falls under 1 satoshi we no longer call it "extremely low" we call it dead coin.
no inflation change can save or change the price anymore.
current price is 0.6 satoshi!

spam attack on a network where blocks are empty is useless.
asking for more fee on a network that nobody uses is also useless. which means whether fee was 1 zeit or 1 trillion zeit that would have made no difference.

why would you even need offchain when your chain can handle it ;)
and FYI if we wanted to use third parties we would have used banks not cryptocurrencies.

In my opinion (which is result of my research) NEM is going to have highest TPS among blockchain cryptos and IOTA is going to have highest TPS in general.

The thousands of TPS on NEM will definitely happen on a privatised version, not necessarily the public chain.

Right now I seem to remember they said the public chain is limited to about 5 TPS. If the privatised upgrade is included it'll be high but maybe not stellar. I don't think it's very clear yet.

Yes, I agree with you. NEM (XEM) has very big potential. very good dev team.

Hmm,
No need to Lie,
our orphan rate can be viewed here.
https://chainz.cryptoid.info/zeit/#!extraction (https://chainz.cryptoid.info/zeit/#!extraction)

BTC average is 3 orphans per day,
Our average is ~180 per day
So ~60X the orphan rate not that 1500 to 2000 , you pulled out of your butt.

But we have that 180 Spread out over 2880 blocks per day.
Less than 6% of the total. No Big deal.  ;)





Marketcap bounces between $250,000 & $600,000 at the present time,
If near ½ million Dollars is dead, then call us Zampires , cause we will be here forever.
And that is with an inflation rate of 5% per year, when we move to .0005% per year , price has nowhere to go but up.




You're a little dim , you claimed a stress test is too much for ZEIT,
but you are afraid to try one. Fact is we do have 20X their ONCHAIN transaction capacity, we can handle 20X BTC onchain volume.
No matter what you think.



LOL, that is the Difference ,
ZEIT does not need Offchain transactions for capacity , we have plently of onchain capacity.
However when people use ZEIT for retail purchases (Gas Stations or Grocery Stores or Coffee houses),
they need transfer speeds of ~ 5 seconds which is only possible offchain , thru 3rd party systems such as exchanges or gift cards systems.

Banks with their fractional reserve lies are what is bad,
a payment system based on ZEIT that can not be counterfeit or manipulated like fiat is Good.

What happened to the Paypal 150tx/s and/or the VISA 2000tx/s scaling... am not hearing much about those levels in this thread...

Has anyone seen the tweets by Fuserleer, he has shown videos of 220ms confirmations, yes milliseconds, and that test network included UK, Denmark, and USA off the self nodes. This is what is coming down the turnpike in 2017.

200ms sounds physically impossible in a public decentralized network for a transaction to propagate through, not even talking about confirmation.

IRL there will be slow laggy nodes, badly connected nodes, nodes behind the great firewall etc.

That being said I wish Dan good luck with this, hope he releases something after all these years. Will definitely check it out then.

We're at 220tps at IOTA, public stresstest using 250 globally distributed nodes (with artificial latency and package drop). Next test to follow soon.
