P.S. The only viable solution is to build such a project on top of an existing secure immutable decentralized blockchain. Like a bitcoin side-chain that is merge mined by same bitcoin miners.
There may be other solutions like using a different algorithm other than PoW that I can not think of right now.
This was my original question - How could you use existing blockchains to provide a decentralized version of twitter? The
https://memo.cash/ mentioned above does this but poorly. I will look more into this option as I agree, this is probably the best option. If I found a blockchain that is secure and cheap to send transactions, maybe I could build a website that reads all transactions in said blockchain and replicates a twitter feed using the messages in each transaction. Could even require the beginning of the message to have a specific key to remove transactions not intended to send message.
If the problem is only cost of BCH transaction, you could reiimplement memo.cash protocol on different blockchain. The protocol specification is available on
