Many application stacks interact with a backend server using a request- response pattern. smart-contracts, however, require a diﬀerent architecture when used as an application backend.
One solution is to emit events from the contract after a request.
A DApp then subscribes to new blocks and checks for any events from the contract, applying updates accordingly.
Write a blog post showing how to build a DApp with a smart-contract backend on a CENNZnet blockchain.
## Expected Outcome
It should show the “emit event and watch” pattern. Additional bonus points for additional architectures or solutions.
Feel free to review our documentation and Github repos to get started:
It should use the CENNZnet js SDK in the DApp.
The smart-contract should compile and deploy on a CENNZnet blockchain.
