Hello!
I have created a simple one-file blockchain-based chat — Waves Wall.
The wall displays messages from last transactions.
You can send Your message by typing it in input box and pressing the Enter key.
You can change amount (0.001 - min).
Operations are performed by the client.
Don’t forget to install Waves Keeper 
Feel free to create issues and pull requests.
The project, including all technical details, will be described soon.

Works great, cool!
reading the attechment make sense for bussiness. 1000 tx = 1 waves. work on gui it is not a huge revenue but anyway
You should add alert requesting to install keeper to the site
Thanks) I thought about it
update: waveskeeper check added
I’ve changed update procedure) now it first check last tx then update if needed
Update
Send button and chars counter added.
Link in messages leads to tx now.
Do you need pinned message? Last message with more than the minimum amount (0.1 for example)
Now it works with Payments API.
You can use it without Waves Keeper (or with it)
Should I add the server part, which will make requests to the blockchain and send data to the client during updates?

You can change amount)
waves .001 fee for sending to the wall can be lowered?

min amount is 0.001 waves now
it’s possible to send messages from mobile devices
Is there a version of this that uses testnet only?
