The main difference is that participation in the Loyalty Pool enables AdEx governance.
Thanks to snapshot.page, loyalty pool participants (ADX-LOYALTY holders) can vote on various proposals related to the development of AdEx, both the underlying protocol and the ad network on top of it.
Proposals will be submitted by the AdEx team and voted on by the community, and based on this signalling we’ll make decisions regarding the road ahead.
At this stage, proposal voting outcomes are not binding, unless explicitly marked as such.
This governance mechanism can be used to change the pool parameters, such as loyalty pool price-issuance steps, Validator Tom pool staking incentives, publisher and advertiser incentives, etc.
Additionally, unlike regular validator pools, the loyalty pool is tokenized. This means it wraps ADX in its own token (ADX-LOYALTY) that can be transferred, traded, locked for governance or otherwise interacted with, to take advantage of the vibrant DeFi ecosystem on Ethereum.
This token is essentially an interest-bearing ADX derivative, similar to the Yearn Finance vault system.
