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?
