Hello @nhamnhinhanh! We appreciate your being here :)
Steemit is a blogging website that uses the Steem blockchain to reward publishers. But luckily it doesn't end here. Steem is capable of so much more than blogging.
- Busy.org is a social network based on the Steem blockchain.
- D.Tube is a video platform built on top of the Steem blockchain and the IPFS peer-to-peer network.
- Utopian.io is rewarding contributions to Open Source projects.
- SteemStack.net is a discussion board build on top of the Steem blockchain.
Have a good time and see you around!
