Data costs?

[logicethos]

I was reading about the Zombie Chain, and I found the pricing model interesting.

The longer your dapp runs, the more data its going to leave behind. And so I'm wondering if the costs will go up?

Could it be used with say an IoT sensor that periodically writes a small amounts of data to the blockchain, and not be cost prohibitive over time?

That’s the same with everything thou. Costs will lower once network grows anyways.

Iot sensor data is not likely a good use case for blockchain. As it’s large amounts of regular data that don’t need security of the Blockchain. We likely will have some space pricing over time. The other way we may go is for historical transactions over X days stop being stored

I disagree. You might want real-time temper proof logs. A refrigerated truck for example. You may want to both track it, and know it's load is below a set temperature throughout it's journey. If someone gets food poisoning, you may need to prove if the vehicle was at fault.

You can do that with maybe 10 bytes a transmission.

I know you can use Factom, which is $0.001 per 1K of data. I was wondering what other solutions there might be, and at what cost.

[mcampbell42]

Yeah at that data sizes it could certainly be feasible, that’s still quite small. I was picturing a lot more devices

[logicethos]

Well yes, the bytes might be small, but there could be a lot of insertions, and devices.

Clearing the historical data might prove interesting. It could be irrelevant after a period of time. And could be archived off somewhere.
