Pebble IoT Prototyping board is an interesting example of a Blockchain "Hardware Oracle": it's designed by IoTeX in partnership with Nordic Semiconductors and works in combination with the IoTeX Blockchain by providing a "trusted, verifiable view" of it's surrounding environment:

It provides:

- Temperature, Humidity, Barometric Pressure
- Air Quality (VOCs)
- GPS location
- 3-Axis accelerometer data
- 3-Axis gyroscope data
- Ambient light measurement

it signs and sends the signed data to either an MQTT server or to the blockchain directly, such that both the data and the data source can be verified by anyone through the signature.

As it's equipped with secure hardware onboard to securely generate and hold the private key, this represents a valid, innovative design for building "Trusted Oracles".

There is also an idea-thon going on! (you can win prizes up to 200$ or a Ucam (another blockchain-enabled product available on Amazon!)

Reading real-world data from a smart contract is a well-known problem: the consequences of introducing non-blockchain (i.e. "non-trusted") data into the blockchain for dApps to "react" to real-world events are severe, potentially resulting in the cancelation of most of the benefits that blockchain can provide, especially "immutability" of data.

This is a fascinating field of research, known as the "Blockchain Oracle problem": the problem of designing an "oracle" that acts as a bridge between the real-world and the blockchain, taking care of "digesting" the real-world data, make sure that it is trusted, verifiable, and tamper-proof, then make it available to dApps: Chainlink approach is one way to tackle this problem, but one more interesting approach is with "secure hardware".

One such type of device is going to be released soon by IoTeX (an IoT-Blockchain project), and they are launching this interesting "Idea-thon" where you can think of possible applications of these IoT secure devices, that are well-suited to send data to be used by blockchain applications that can really "closing the trust gaps in the real world" as they say.

I think this is an interesting competition, the prizes are not high but initiative is really interesting:

Cos’ è IoTeX?
IoTeX è l’infrastruttura blockchain auto-scalabile e incentrata sulla privacy fper l’Internet of Things (IoT). Il team globale IoTeX è formato da ricercatori in Crittografia, Sistemi Distribuiti, e Machine Learning, ingegneri di alto livello, ed esperti creatori di ecosistemi. IoTeX IoTeX sta sviluppando al suo interno varie innovazioni per spingere in avanti la frontiera della blockchain 3.0, che includono una architettura blockchain-in-blockchain per i dispositivi IoT eterogenei, un meccanismo di consenso Roll-DPoS super veloce, e algoritmi leggeri per la salvaguardia della privacy. IoTeX sta portando il coordinamento dei dispositivi autonomi alla portata delle masse, “collegando il mondo fisico, blocco per blocco”.

Hi! Yes, the way you described it is mostly correct! I would only add that the Blockchains-in-Blockchain architecture is one aspect which allows IoTeX to scale, the other fundamental aspect is the Roll-DPoS consensus linking together the subchains, and when the network grows (i.e. more subchains get added) Roll-DPoS  kinda "replicate" itself into multiple consensus groups each of which manages the consensus of different subchains in parallel, thus increasing the TPS.


Well, the development is going on at a very fast pace! Right yesterday the Mainnet Preview code has been released, an a first implementation of Subchains + Corsschain transactions has been showed.

Hi! Thank you for your interest in IoTeX!

I assume you mean the demo video of the latest Testnet Beta release on the website, right?

About applications well, Internet of Things itself has unlimited applications, and blockchain seems to be the right technology to make it finally real.

Hello Anivika, thank you for you interest in IoTeX!
Not sure what comparison chart you are referring to (maybe you can post the link for me to check?). The IoTeX blockchain development is progressing at a very fast pace, and all the deadlines on the (very strict!) roadmap have been respected so far. The IoTeX Testnet Beta has just been released on August 29th, please check it out: all the relevant links are on the homepage here www.iotex.io. You will be able to test the web wallet 1.0 and even try the first smart contracts implementation!

Please let us know your thoughts! And feel free to ask if any doubts arise!

Hello Mi chael! Thank you for your support!

Please feel free to check out our Testnet and sen us your feedback!

Go to the website for the links => https://iotex.io

Hello! Thank you for supporting the IoTeX Project!

Please stay tuned for the Testnet Beta Release today, less than 15 hours left!!

Hello Dayattaufik!
Thank you for your support!
IoTeX aims to become the “obvious” choice for any IoT manufacturer or DApps developer who requires a blockchain to deliver his products/services.

To do so it requires hard and constant work on the technology in the first place. Industry ready blockchain solution is higly required in the IoT space, where the manufacturer can easily setup his own subchain with those features that best suit his devices such as full privacy or high transactions throughput, or smart contracts. Also, partnering with companies that will actually develop their products on IoTeX, bringing real value to the project, is critical.

For this reason, the IoTeX team is fully committed at this moment to deliver the technology, within a very strict roadmap, to quickly reach a “ready to use” mainnet, and at the same time the partnership program has just started: 7 partnerships have been achieved during August, both with blockchain security expert companies, and with companies ready to develop their products on the IoTeX network ranging from bike sharing devices to medical tracking devices to wearable devices.

We believe the IoT industry requires a solid and reliable blockchain, which can really solve the scalability problem without sacrificing full privacy, instant transactions and smart contracts, and also as flexible to be applicable to most IoT scenarios. And we believe these goals can be achieved with proven blockchain technologies already existing, plus working on innovative solutions that allow them to scale to billions nodes and be lightweight enough to be run by low power devices even providing full privacy, and fast enough to enable low latency demanding scenarios.
