I built an open social protocol where every interaction is a bitcoin transaction:
- Posts, replies, reposts
- Follows & unfollows
- Profile updates
It's called OP_RETURN Social (ORS)
Try the reference client for free here: https://opreturn.social
- All interactions are published to testnet (Mutinynet)
- Optionally pay to publish posts you want to preserve to Mainnet
Free transactions will be shown by a gray box icon, instead of an orange one.
ORS is "BIP-110 compatible" by concatenating 80 byte OP_RETURN outputs from multiple transactions. The cost to do this is negligible.
OP_RETURN is a provenly-prunable way to embed arbitrary data in bitcoin without bloating the UTXO set. Any ORS post FUNDS the network.
I think there are some fun things to be explored, especially around WoT & reputation, to both reduce spam and create quality feeds. I also plan to add notifications, reactions, and search next.
Everything is open source - If you're interested about the protocol, you can learn more about it ORS here: https://ors.dev - try building your own client!
