Which cryptocurrencies reward useful computation?

Here's my list so far

Storage sharing

Storj - centralized, but pays out in crypto

Siacoin - Fully decentralized storage

Filecoin - Decentralized storage, but requires a lot of resources to participate.

Arweave - Decentralized permanent storage

BTFS - Bittorrent file system, effectively get paid for pinning IPFS files

Network sharing

Mysterium - Get paid by acting as a VPN provider / exit node

NKN - Seems somewhat abandoned, relay network traffic

Utopia - Relay network traffic

PKT cash - Currently bandwidth hard POW, aims to transition to becoming a mesh vpn

Helium - LoRaWAN to internet gateway

Nodle - Bluetooth low energy to internet message relay

Subsidised compute - contributions to existing volunteer compute projects

Curecoin - Get paid for participating in folding@home

Banano - Get paid for participating in folding@home

Gridcoin - Get paid to participate in BOINC projects

Decentralised compute - Providing your computing power directly

Flux - Decentralised cloud compute, fixed node sizes. Requires a fair bit of collateral compared to the amount of earnings

Akash - Runs on kubernetes, can allocate any amount of resources

Golem - Primarily GPU compute focused

Are there any projects that I've missed, or any categories that I missed?
