I think we are going to see a lot of distributed and light mining solutions crop up and that in a more mature web3 ecosystem much of the mining will be done on end users' devices.
An example: imagine that the Evernote app mined EvernoteCoin (or FileCoin/Truebit/whatever Evernote is built on) in the background while you used the Evernote app.
The benefits of this are three-fold:
- Evernote wouldn't have to compete against other distributed networks for miners’ hash power.
- Both the security and throughput of the Evernote network would scale with the amount of Evernote users.
- It’s an alternative to the ad-supported model: mining would give Evernote users a way to automatically pay back their Evernote bill and get to use the service for “free".
The challenges are that:
- Data and battery are scarce on end user devices and mining could deplete both.
- Because most of the mining would be done by the main app client, this could be seen as more centralized.
- Before hitting a critical mass of users, a network with only a few desktop and mobile miners could be more easily susceptible to 51% attacks by miners with powerful machines.
There are solutions to the above, such as only mining on devices plugged in with full battery, letting the user toggle mining on/off, allowing traditional mining pools as well as mining on end user devices, etc.
I think we’ll start seeing this sooner rather than later. I am excited about it.
