Will outsourcing POW ever be an issue?

Of course not all IoT devices can do proof of work. First of all, all IoT devices is a huge variation of devices. For that generalization this question can simply be answered with a no. Especially ...

Will outsourcing POW ever be an issue?

PoW can be quite heavy on the resources of IoT devices, But I believe that we can expect dedicated cheap IC's (chips) in the future to counter that. If you run multiple small devices a "hub" for those ...

Will outsourcing POW ever be an issue?

JINN is planned to be a $1 (or otherwise extremely affordable) chip designed for taking care of PoW -- keeping in mind that PoW doesn't become more difficult over time, JINN should theoretically be ...

Possibility of installing IOTA on a micro-controller?

It is feasible to use the microcontroller as an IOTA wallet. For example, you can store your IOTA seed on the flash, generate addresses from it, generate sign transactions. One option to get started ...

How are taxes paid in the future if finally my car pays for parking?

Interesting topic for the protocol. Currently I think it would be suitable if you use the messages for it. You have then just to include tax rate etc. You can also use encryption for it. Iotas masked ...

Multi seeds or multi addresses for sensors

As https://iotasupport.com/how-addresses-are-used-in-IOTA.shtml explains: The generated addresses are part of a sequence of one time(!) keys generated from a single seed. Using multiple addresses of ...

How to install IOTA in a small device supports LoraWAN?

LoraWAN is a protocol for data-transfer (not a device). It's a very low level protocol, specially designed for low power devices. AFAIK, LoraWAN is designed in such a way that a small device can send ...

Possibility of installing IOTA on a micro-controller?

Working on it: https://github.com/embedded-iota/iota-c-light-wallet (on my own fork. Will push it to embedded iota when it works fine.) The address generation works. I work currently on the transfer, ...

How to Securely Outsource Proof of Work Calculation?

The outsourcing of POW for light clients is already default. The attachToTangle command on the IRI does the POW and all public nodes (e.g. http://iota.bitfinex.com:80) manually deactivated it because ...

What is the lower limit of energy usage for an IOTA transaction?

A low min value can only be given as an averaged value, since finding the nonce (pow) is a statistical process. Energy consumption for this pow process depends on how effective your cpu is working (...

How will IoT devices know the state of the network?

Tip selection and PoW are completely different things, which do not necessarily have to happen at the same point. Tip selection performs MCMC on the tangle to find two transactions (or rather their ...
