mmm.. I don't think this is a matter of one development team which is better than the other - though IoTeX can count on a team extremely well balanced among Research Scientists (so far 10+), top tier engineers from Google, Facebook, Uber, Intel, Bosch, and experienced ecosystem builders (check out the curriculum of Jing Sun, she led 40+ investments in blockchain, security, and IoT!).

Rather, I think it's a matter of design: IOTA may have a huge development team, but if they have to spend all of their energy in trying to overcome the IOTA limitations due to it's DAG design trying to adapt it to IoT, then all that "development power" is just wasted. IoTeX has a very clear design, where each and every aspect required by most IoT applications is taken into accound in advance using proven technologies and innovating those where it's required. Innovations happen thanks a very solid academic background of the Ph.Ds and Research scientists who are part of the team, through the common Academic Paper Publication and Scientific community review process.

I think this is a very solid and promising approach that, according to the roadmap, will give its results very soon. Indeed in August they just launched their partnerships program online and have partners with real-world applications ready to be developed ranging from health-tracking IoT devices to IoT-collected data marketplace, to Smart Home devices. All of them leveraging the unique IoTeX full privacy feature, smart contracts and Instant consensus.

Honestly guys, I think this is really going to revolutionize the IoT industry on next year.

User zimne above posted the whitepaper and other papers links, I’ve read them (well, I could only understand 10% of the Yellow Paper and DKSAP-IoT Paper as they are all about mathematics and cryptography innovations, but the whitepaper which is still an academic paper itself can be read if you have intermediate  engineering/math education).

Let’s take the full-privacy algorithm which IoTeX provides (and improved over the Monero algorithms by making them lightweight and capable of running on low power devices): I think apart of (legal)e-commerce and few other applications, most IoT uses wil require full privacy. Think even to the basic E-Charger application of IOTA: how hard it would be for people who knows your car id on the Iota network (say the car manufacturer or your husband/wife) to track the places you have been to?

I do not know how many of those interested in the intersection of the blockchain with the Internet of Things have actually noticed the IoTeX project (www.iotex.io). While the only noteworthy project in the sector still remains IOTA, it is undeniable that it'is still far from being a network that can be used in production due to the highly unknown technologies it is based on and all the hard work the IOTA team has to go through before they come to a stable and features-full product suitable for real-world use.

On the other side, the IoTeX team, made up of over 10 scientists researchers, plus numerous engineers from giants such as Google, Facebook, Uber, Bosch, etc., has not only designed the perfect blockchain to act as the infrastructure for the future IoT, but they are promptly releasing excelent and working code, following a though roadmap that will lead to the Mainnet Alpha already by the end of 2018 (mainnet preview expected by the end of October, and Testnet Beta by end of this month).

The IoTeX blockchain is designed to be operational right from day one, and is the only one to provide unlimited scalability (through subchains and crosschain communication), high transactions volume that grows together with the blockchain, instant transactions, total privacy (covering sender, recipient and transaction amount), proprietary lightweight encryption algorithms optimized for running on embedded devices, smart contracts, and much more.

In line with what the Team anticipated in June, just a few weeks befor the beta test release (expected by end of August), the team's strategic partnerships publication has just started: a few days ago the first strategic partnership was announced (https:/[Suspicious link removed]/41nllyjnrR) with Lineable (https://www.lineable.net/), a Korean company that works together with the local giant SK Telecom and with the Korean police, for the production of at least 1,000,000 devices tracing the health of Alzheimer's patients, that will use the IoTeX blockchain for communication and data transfer!

Once the mainnet has been released, IoTeX will in fact be the only blockchain which is actually working for IoT devices, and which provides all the fundamental features required by the Internet of things: massive scalability, high transaction volume, instant transactions, total privacy, smart contracts and low power devices support.

I highly suggest anyone to look into this project!

Well, my favourite one is IoTeX (www.iotex.io | www.t.me/iotexgroup): the team is too good to be true, and after only three months from token issuance the mainnet preview is expected for October 31st.

I agree that there are no active IoT mainnets except IOTA, and that makes things even more interesting: even IOTA, after one (or two I'm not sure) years of development still could not overcome many limitation due to the Tangle design (like an "innovation in blockchain innovation") which could take still years before it finds it's role into the distributed networks space.

If IoTeX will deliver, I think very soon we will have the first IoT blockchain actually working: they provide:
- unlimited tps,
- massive scalability,
- instant tx confirmation,
- full privacy,
- subchains to compartimentize different devices classes/manufacturers/applications,
- lightweight cryptography to run privacy even on embedded devices...
- smart contracts

all of this is in testnet already, to be delivered in mainnet-preview by October 31, developed by a team of PhDs, expert engineers coming from Facebook, Google, Uber, and Bosh, and many other top level members.

Honestly, I see that like the IoT leaders with a ready working blockchain very soon.  

Well, I didn't say I did a comparison, I said that I'm currently doing it, and that's the reason why I'm asking these questions.


I checked out your link, so based on what I can read there IOTA was not designed with privacy in mind, and research is ongoing to find a solution to implement some level of privacy, at leat transactions mixing, but that's made difficult basically because the missing "consensus/mining" concept of IOTA does not allow such feature development.

So I think we can safely say IOTA is missing a privacy feature at the moment and adding it, even a partial privacy implementation, is made complicated by the initial IOTA design.

What about transactions speed? Can anyone provide numbers on how fast transactions are getting confirmed on average, and how the confirmation speed is expected to change in a real IoT scenario where billions of devices are connected and transacting?

Is this the official Announcement thread?

I'm currently comparing other IoT projects to IOTA, and it seems to me that IOTA really lacks critical features.

One of these is privacy: I mean, how can IOTA ever become the infrastructure of IoT if it can't guarantee privacy? Connecting IoT devices to a global network means sharing very personal informations, possibly more than what we share now on socials by means of our smartphones. What about our home devices? And health data?

Also I've been left to the status of IOTA in October 2017: at that time the wallet was having huge problems connecting and transactions didn't go through. How is the transaction time at the moment? Is it like 2 minutes as someone wrote above? If so, how do you expect IOTA to support IoT transactions? In IoT scenarios, embedded devices are expected to react relatively quickly to changes in the environment (think of house doors closing when I leave my apartment... 2 minutes looks like enough time for a thief to make it into my house).

There are excellent blockchain solutions popping up out there, look at IoTex: is IOTA going to be up to it? Honestly, I don't think so.

I'd like to bring this recent project (IoTeX) to your attention: does anybody know about them?

I'm carefully following them since April, and honestly I can't find one single reason why this project shouldn't become the IoT leader in one or two years.

I mean, they really carefully designed the perfect blockchain for the IoT, and they are delivering what they promised so quickly, so accurately, AND in the complete silence  

Among other features, they designed:

Subchains
This allows to compartimentize different categories of IoT devices into the most suitable blockchain architecture for each of them: indeed no single blockchain design can fit any application. Besides that, this "blockchain-in-blockchain" design allows to infinitely scale the blockchain: because no single network can manage tens of billions nodes connected, nor most IoT nodes are able to work on such a huge blockchain. For example, autonomous cars can live into their own subchain, and they need to store and validate only those transactions related to their subchain while, thanks to crosschain communication and instant transactions finality, they can still interact with any other device on any subchain almost real-time!

Crosschain communication & Instant finality
Crosschain communication, together with the instant finality feature of their consensus mechanism (i.e. each transaction is final on the first confirmation) allows for any device to communicate almost instantly with any other device, even if it's in a different subchain.

Full privacy
The IoTeX blockchain supports full privacy (like the one implemented in Monero, where both the sender, the receiver and the value of the transactions are cripted), but the team improved it to make the algorithm lightweight enough to be implemented on embedded IoT devices. This not only allows privacy for the IoT (which is a killer feature, and no other IoT blockchain implemented), but depending on the subchain owner, he can decide if he wants this privacy feature to be enabled for his subchain or not.

Roll-DPoS: more democratic, scalable, secure version of EOS DPoS consensus
The consensus mechanism is based on the EOS DPoS, because of the high throughput required for IoT but, as we know, IoT requres huge scalability which in IoTeX is obtained through subchains. The consensus mechanism is supposed to support this scalability (and the instant finality of transactions) as well, and the EOS DPoS is definitely not enough. The in-house Roll-DPoS consensus from IoTeX allows the network to auto-scale accordingly with subchains: the bigger the number and size of the subchains, the bigger the pool of delegates that will be used for the consensus (i.e. not a small and fixed number like in EOS). Therefore, the Roll-DPoS improves on the centralization problem of EOS, allowing also for more security throug an advanced additional random mechanism to select which delegates, among the ones in the pool, will run the consensus at each round.

There so much more about IoTex to say that, after only 4 months from token issuance, it would require to write a book! One thing among all: this project is getting developed by the best team I'm aware of in crypto!

So, what do you think about them, and about the others IoT blockchains? Is there any that can compare?
