VSC Network is currently being developed right now, funded by DHF. It aims to bridge EVM chains to Hive and one of the services is swapping other coins to Hive v.v.; it will use staked HBD as the basis of the Resource Credit for VSC network but I'm not sure if there will be additional incentive to that other than the 15% APR provided by Hive blockchain.
The other one, SpendHBD has been around for months now and it aims to facilitate circular economy by onboarding merchants to the platform and encourage them to accept HBD as payments for their products or services. This is what I'm excited about because it this becomes adopted by producers, merchants, shops, and consumers then we can have a strong use-case for HBD.
A few years ago, there was a group of Hive users that forked the chain and get rid of the downvote feature. They still exist today and there is an active community posting. Although the token’s value is low there are still active users posting.
There was a time when their platform was bombarded by spammers and I believe they fixed it by preventing the spam accounts from posting or commenting.
