Other than proof of stake I've heard of two validation systems:
1. Proof of space and/or time:
https://en.wikipedia.org/wiki/Proof_of_space#:~:text=A%20proof%20of%20space-time,keeping%20the%20reserved%20space%20unchanged.&text=It%20is%20related%20to%20a,tradeoff%20between%20space%20and%20time https://en.wikipedia.org/wiki/Proof_of_space#:~:text=A%20pro....
2. Proof of authority:

Not sure either makes a huge difference
- skerit 5y agoHelium network's proof of coverage is also interesting.
- CuriousCosmic 5y agoProof of Authority is extraordinarily useful but it's not inherently complex by any means (really it's just the old school consensus problems). I'd argue though that Proof of Authority definitely is the most useful outside of Proof of Stake and the slowly maturing Proof of Useful Work consensus systems. It's simplistic but it perfectly covers the needs of a lot of government systems.
- noxer 5y agoBefore these and even before PoS there was FBA consensus which is the true successor of PoW designed by ex-BTC devs who saw the problems with PoW and actually came up with something better rather than just replacing the worst part of PoW with something else.
